Why is "Treating the textbook '1% price to +11.1% operating profit' as a rule of thumb at every elasticity" a common mistake when using the Manufacturer P&L Sensitivity?

Symptom: The annual plan promised a 5% list lift on a -1.8 elasticity SKU and forecast a contribution lift of more than 50%, five times the textbook 11.1%. Actual landed at +2.4% versus base. The CFO challenged the math, the planning team blamed the model, and the credibility of the entire RGM cycle was undermined by a missing elasticity assumption. Fix: **The +11.1% rule assumes inelastic demand and a different profit denominator.** At FMCG-realistic elasticities a 1% price lift delivers about +1.1% of brand contribution at -1.5, +0.7% at -1.8, and a small loss at -2.5, nowhere near 11.1%. Use the calculator's actual scenario response, not the textbook headline. Price and terms together do not reach the bar either, and they do not even beat price on its own. On this SKU, +3% price with -2pp trade terms lifts brand contribution about 1.9%, and +5% with -2pp about 2.2%. Moving list price alone and leaving the terms where they are gets you +2.6%. Reaching EXCELLENT takes a premium mix shift and a cut to the promotional calendar, and it is those two that make it affordable to give the buyer terms rather than claw them back, which is the walk Step 7 makes.

Why is "Modeling levers in isolation when interaction effects dominate" a common mistake when using the Manufacturer P&L Sensitivity?

Symptom: The trade plan moved Price up 3%, Trade Terms up 2pp, Promo Depth up 5pp, and Premium Mix up 5pp simultaneously. The two positive single-lever readings, +1.8% for the price and +2.4% for the mix, were the ones quoted in the approval; the 2pp of terms (-2.6% on its own) and the 5 points of depth (-4.8%) were waved through as customer investment. The combined scenario landed at -2.9%, CONCERNING, with Promo Intensity tipping into HEAVY. Note that the four readings do not simply add up, and they rarely do: the terms and the deal plan are both supplier money in the same customer margin, so the retailer's response answers to the two together rather than to each in turn. Fix: **Test combined moves as a single scenario before approving the trade plan.** The Tool's lever interactions are non-linear and asymmetric. A price lift shrinks the volume a mix gain lands on. A trade-terms cut lifts the net price your remaining volume earns and costs distribution at the same time, and a deeper promo raises the gross-to-net rate on every unit. Use the calculator to model the full simultaneous combination rather than the sum of the single-lever lifts, and read the negative levers as carefully as the positive ones.

Why is "Pursuing volume recovery with price cuts on elastic SKUs" a common mistake when using the Manufacturer P&L Sensitivity?

Symptom: The brand lost 4 share points over two quarters and the response was a -5% price cut as a defensive move. Brand contribution dropped 5.4% in the next quarter. Sales blamed retailer execution, but the math was fundamental: at -1.8 elasticity and 42.1% margin per unit (the Margin Safety reading), the break-even elasticity for a 5% cut is roughly -2.7. The brand was less elastic than threshold; the cut destroyed contribution mathematically. Fix: **Compute Break-Even Elasticity before any defensive price cut.** Required volume gain = the price cut divided by (margin per unit as % of net price, minus the price cut). The break-even elasticity is that gain divided by the cut. At 42.1% Margin Safety and a -5% cut, the formula yields a 13.5% required volume gain, so the break-even elasticity threshold is roughly -2.7. Any actual elasticity less elastic than -2.7 means the cut destroys contribution. Cross-reference with the **/tools/break-even-calculator** Tool for the full Break-Even Elasticity diagnostic. Defensive responses on elastic SKUs usually need to come through a shallower deal plan or a premium-mix lift rather than a price cut. They rarely come through clawing trade terms back, because the on-invoice share of those terms reaches the shelf and puts your own ticket up.

Why is "Assuming a cost rise can be passed straight through on price" a common mistake when using the Manufacturer P&L Sensitivity?

Symptom: Procurement signaled a 5% COGS inflation and the plan responded with a +5% list price one-for-one pass-through. The customer accepted the list move. The next quarter, brand contribution landed -4.7% versus base, because the 9% volume loss from the elasticity response took back most of what the price gain had recovered. Fix: **One-for-one pass-through does not cover a cost shock at the default elasticity.** A 5% COGS shock with +5% price still leaves brand contribution 4.7% below base on the default biscuit SKU. No price-only setting gets it back either: the best is +7.9% list, still 4.2% down. Reaching for the customer's terms line buys almost nothing. A +5% list move with -2pp of trade-terms recovery takes you from 4.7% down to **4.6% down**, one tenth of a point, because what you collect on the invoice the retailer puts back on the shelf ticket. Trimming the deal plan on top peaks at -5pp and 4.0% down before it turns around on you. The combination that does clear it runs the other way: **+8% list, four points of terms given to the buyer, +6pp of premium mix, and the calendar cut hard (depth -12pp, frequency -15pp)**, which lands 1.4% above base. Fund the customer properly and take the money out of your own promotional calendar, rather than trying to take it out of their margin.

Why is "Settling for a HEALTHY contribution band when EXCELLENT is reachable" a common mistake when using the Manufacturer P&L Sensitivity?

Symptom: The annual plan landed at +0.6% brand contribution versus base (two points of terms recovered, nothing else), all four health bands green or amber, and the operating committee signed off on it. The same SKU was capable of **+8.0%**, worth **$176,736** against base and **$164,567** against the plan that was signed. Nobody proposed it, because it starts by giving the buyer money: +4.5% list, four points of structural terms handed over, six points of premium mix, the deal calendar cut twelve points of depth and ten of frequency, and $100,000 put behind the brand. Note what is doing the work on that list, because it is the lever the meeting treats as untouchable. The two calendar cuts are worth nine points of brand contribution between them. Without them the give-back is unaffordable and the whole plan sits at -1.7%. That plan also grows net sales 1.0%, which is the condition it is built to: more profit on a shrinking business reads better on one tile and loses the room. Fix: **A scenario in the HEALTHY band, 0 to +8%, is acceptable and unremarkable. EXCELLENT is what justifies the planning effort.** A scenario in the HEALTHY band (0 to +8% brand contribution lift) is acceptable but unremarkable. EXCELLENT (at or above +8%) is the band that justifies the planning effort. Run combined-lever scenarios systematically: every annual plan should test (a) base, (b) cost-recovery if applicable, (c) margin-expansion play, (d) deal-plan retune, (e) premium-mix lift, (f) full combined. The CFO test: does the recommendation sit in EXCELLENT on Contribution Health while keeping the other three health bands in green or yellow? If not, you are leaving margin on the table.

Guided walkthrough

Explore the tool, from setup to common mistakes

Five short sections explain the scenario, what each control does, how to read the output, and the mistakes to avoid. Open whichever helps. The tool above works without them.

5.1Scenario setup

The starting SKU, market, and assumptions the model makes.

You are the Commercial Director at a mainstream FMCG biscuit manufacturer running the annual planning cycle for CrunchField Original 300g. Regular list price $4.29, 2 million units annual volume. Cost structure: COGS $1.72/unit, outbound distribution $0.34/unit, fixed cost $800K/year. Gross‑to‑net totals 17% of gross sales: 5% on‑invoice, 3.5% off‑invoice rebate and 2.5% other terms are the three rates you negotiate once a year, and the deal plan (20% off on 30% of volume) costs another 6%. There is no premium variant in the mix yet; the premium pack bills at 1.4x list and costs 1.15x to make, and the Premium Mix Shift lever moves volume toward it. Price elasticity sits at -1.8, a planning placeholder rather than a measurement; change it to whatever your own brand has measured, because every result below moves with it.

The current scenario is on track to land $3.00M in annual contribution at a 51.7% gross margin and 42.1% contribution margin, which leaves $2.20M of brand contribution once the fixed block comes off. That last line is the one the Contribution Health band grades. All four health bands read healthy. Now Marketing wants a 3% list lift, Procurement is signaling 5% COGS inflation on cocoa and packaging, the customer is pushing for 2pp more trade investment, and the brand team wants to shift 10pp of mix to premium. Your job: model every move and combination, see which scenarios beat base and which destroy it, then bring a single decision recommendation to the operating committee that the CFO will sign off on.

Your objective

Use the calculator to find which combination of pricing, cost, trade, promo and mix moves lifts brand contribution by at least 8% versus base (the EXCELLENT line on Contribution Health). The other three health bands have to stay healthy or better. Then test the textbook pricing rule of thumb against the actual elasticity-driven response on this SKU. A list-price move on its own will not get you there. Clawing structural terms back will not either: it peaks under two points and is losing money by four. The reason is that the on-invoice share comes off the retailer's bill, so they put the item up on the shelf to recover it. The last stretch comes from the deal calendar and the premium mix, and those two are what make it affordable to give the buyer terms rather than take them.

Key assumptions

The calculator models a single SKU at a single channel in isolation. No portfolio cannibalization across pack sizes, no competitive promo overlap, no halo to non‑promo packs. Cross‑SKU effects sit in PPA Lesson 2 Pack Roles and TPO Lesson 2 Source‑of‑Volume.
Price elasticity is fixed at -1.8 for the default scenario. That is a common planning placeholder rather than a finding about any brand. Elasticity differs hugely by market, category, shopper, product and occasion: general averages exist and the real range around them is much wider and entirely context‑specific. Adjust the field in the Product & Pricing panel to whatever your own brand measured. Published bands put value SKUs nearer -2.5 to -3.5 and premium SKUs nearer -0.8 to -1.4, and they overlap.
The four health bands are this calculator's own calibration for a mainstream FMCG line, not a measured industry standard. GTN Discipline turns at 15%, 22% and 28% of gross sales. Margin Safety turns at 50%, 35% and 20% of net price. Promo Intensity scores depth plus half of frequency and turns at 25, 40 and 55. Contribution Health turns at +8%, 0 and -5% on brand contribution. Read them as one consistent yardstick across your scenarios rather than as a verdict on your own category.
Future levers are deltas from the base case, not absolute values. A +5% Price Change means the new list is 5% above the editable base price, not 5% in absolute terms. Trade Terms changes apply proportionally across the three structural lines (on‑invoice, off‑invoice, other), preserving their relative shape. Promotional investment is not one of them; it answers to the two deal‑plan controls.
The contribution line here is gross profit less outbound distribution. Fixed costs come off below it, on the Brand Contribution line, and promotional money is already deducted inside gross‑to‑net, so it never lands twice. The 1%-price‑to‑11.1%-operating‑profit textbook rule assumes no volume loss and a much thinner profit denominator than this SKU has. Freeze volume completely here and the same move is worth +3.2%; run it at the default -1.8 elasticity and it lifts brand contribution by roughly +0.7% (contribution by about half a percent). So the denominator explains about three quarters of the gap to the textbook bar and elasticity explains the rest. The Tool teaches this explicitly.

5.2Controls & toggles

Every input the calculator exposes, its range, and what it changes.

Control	Range	Default	What it changes
Price Change	-20% to +20% in half-point steps	0% (base)	List price change. Drives volume response through the elasticity field (default -1.8). It carries no extra cost of goods, so the part of each EXTRA list dollar that survives the gross-to-net skim, about 83 cents at the base rates, reaches contribution before the volume offset. An ordinary list dollar of volume reaches contribution at about 35 cents, because it arrives with a pack behind it. Price carries more raw leverage than any other lever before volume answers back, and it loses that leverage fast as elasticity moves past -2.0; at -2.5 a 1% rise already loses money.
COGS Change	-15% to +20% in half-point steps	0% (base)	Input cost inflation or deflation, applied to the COGS-per-unit field. On the classic no-volume-loss benchmark, taking 1% out of what a unit costs you delivers about 70% of the operating-profit impact of a 1% price lift. In this calculator, where the price lift also sheds volume at -1.8 elasticity, the cost cut comes out ahead: $34,400 against $15,907. A 5% cost shock on its own takes brand contribution down 7.8%.
Trade Terms	-8pp to +8pp in half-point steps	0pp (11.0% structural, 17.0% total)	Change in the three structural terms you negotiate once a year (% of gross sales), applied proportionally across on-invoice, off-invoice and other. Promotional money is not in here; it answers to the two deal-plan controls. Negative means structural renegotiation of terms; positive means more trade investment. That money is holding listings, facings and feature slots, so taking it back costs volume, and it costs more per point the more you take. It also sits partly on the retailer's invoice, so a claw-back raises their cost and they re-mark the shelf, which costs you volume a second time through the shopper. Taking 2pp out of the 17% total is a typical margin-expansion play and costs about 5.0% of volume; adding 2pp is a typical customer-investment ask.
Promo Depth	-20pp to +15pp in half-point steps	0pp (base 20%)	Discount percentage off shelf when on promotion. Deeper sells more, and each extra point sells less than the point before while costing the same, so there is a best depth and it is shallower than the base. Above 25% absolute, reference prices erode by 2 to 5% per event and the Tool fires a warning. Drives the Promo Investment line directly in the P&L cascade.
Promo Frequency	-20pp to +20pp in half-point steps	0pp (base 30%)	Percentage of volume sold on deal. The more of it goes out on deal, the less a deal feels like one, so every event lifts less. Above 50%, consumers anchor to the deal price as the new normal. Combined with depth, drives the Promo Intensity band via the depth + frequency/2 composite score. Score 25 to 40 = MODERATE, 40 to 55 = HEAVY, at or above 55 = EXCESSIVE.
Brand Investment	$0 to $500,000 in $10,000 steps	$0 (base)	Advertising, display, feature and activation you fund yourself for the year instead of handing the buyer a discount. It sells more units at the price you already charge, so both of you earn on every extra pack: $100,000 puts 70,000 units through the till and $144,893 onto the retailer's gross margin. It costs real cash below gross profit, beside your other marketing cost, so it leaves realization and margin per unit where they were. Each further $100,000 buys about half the volume the one before it did, so there is a best setting rather than an end of the slider: standing alone it is $50,000, worth $11,536. On the recommended plan it is the step that turns +7.5% into +8.0%, and Contribution Health from HEALTHY into EXCELLENT. A $50,000 cheque crosses that band higher, at +8.2%, and the plan still writes $100,000, because the bigger cheque is what carries net sales over the plan's own +1% floor: $50,000 leaves net sales 0.4% down and $100,000 puts it 1.0% up.
Volume Adjustment	-20% to +20% in half-point steps	0% (base)	Non-price volume effects: distribution gains or losses, range expansion, competitive dynamics, category growth or decline. Captures everything elasticity does not. Multiplies the post-elasticity volume.
Premium Mix Shift	0pp to +30pp in half-point steps	0pp (base 0%)	Move volume from the mainstream pack toward the premium one, which carries the premium price multiplier (default 1.4x) and premium COGS multiplier (default 1.15x). Only the shoppers who follow the pack up pay the premium price, and the ones who move first are the ones who wanted to anyway, so the rate falls as you push harder and the rest of the volume walks. A +10pp shift on the default scenario lifts brand contribution by roughly 2.1% and costs 70,000 units; the lift peaks near +7pp and is negative by +15pp.

5.3Step-by-step exploration

7-step guided exploration of the scenario.

Read the default state to anchor the base case
The calculator initializes at all eight levers set to zero. Read the right‑side outputs. Base Contribution $3.00M, Net Sales $7.12M, Gross Margin 51.7%, Contribution Margin 42.1%, Volume 2M units, and Brand Contribution $2.20M once the $800K fixed block comes off. The four health bands: Contribution Health HEALTHY (+0%, and it grades the Brand Contribution line), GTN Discipline HEALTHY (17.0% of gross sales), Promo Intensity MODERATE (score 35), Margin Safety HEALTHY (42.1% unit margin). All four sit in the middle of their bands. Base case is healthy but unremarkable. Anything you do from here either lifts or destroys this $2.20M floor.
Expected outcome: Default Contribution **$3.00M** and Brand Contribution **$2.20M**, all 4 health bands at the cyan / amber middle. The P&L Comparison table shows base column populated and Future column identical (all deltas zero). The Contribution Bridge shows Base and Future at the same height with no movement on the six effect bars. This is your reference state.
Test the +1% price textbook rule against actual elasticity
Drag Price Change to +1.0%. Watch Volume drop to about 1.96M units (down 1.8% from base, exactly the elasticity multiplier). Read Contribution: about $3.02M, up roughly half a percent, and Brand Contribution up the same $16K, which is +0.7% on the smaller base the Contribution Health band grades. The textbook 'every 1% of price is worth +11.1% of operating profit' sets a bar this SKU never reaches, and elasticity is only part of the reason. Freeze volume completely and the same move is still worth just +3.2%. The benchmark divides by an operating profit running near 9% of sales, while brand contribution here is 25.7% of gross sales. Your trade terms also take 17% of the list rise on the way through, so a 1% move adds 0.83% of gross sales to a much fatter number. Elasticity then carries that +3.2% down to +0.7%. The denominator explains about three quarters of the gap and the volume loss explains the rest, which is why 'we are not getting our 11%' is usually a question about your margin structure rather than about your shoppers. Edit the elasticity field and repeat the same 1% move: at -1.5 it is worth about +1.1%, and at -2.5 it already loses money.
Expected outcome: Contribution rises from **$3.00M to about $3.02M** (delta about +$16K, **+0.7%** on Brand Contribution). Volume drops from 2M to about 1.96M units. Contribution Health stays **HEALTHY** (between 0 and +8% band). The Contribution Bridge shows a positive Price bar partially offset by a negative Volume bar, with the Mix, COGS, Trade Terms, and Promo bars all flat at zero because no other lever moved. Before quoting the +11.1% headline in a plan, work out what your own operating margin makes it worth.
Pair +5% price with -2pp trade terms and see how far price and terms get
Reset all levers. Drag Price Change to +5%, then drag Trade Terms to -2pp. New GTN total: 15.0% of gross sales (still HEALTHY band). Volume drops to about 1.72M, down 13.8% from base, and it is worth splitting that number because the two halves are different animals. The price move takes 9% through elasticity. The two points of terms take another 5.3% of what is left, and they do it twice over. Part of that money was holding distribution. The rest of it was coming off the retailer's bill, so taking it back raises what they pay and they re‑mark the shelf to recover it. The shopper meets a pack that went up on your list price and went up again on their ticket. Read Contribution: about $3.05M, up 1.6%, and Brand Contribution $2.25M, up 2.2%. HEALTHY band. This is the classic margin‑expansion play, and pulling both levers together lands four tenths of a point below the best you could do on price alone (+2.6% at +6.7% list), and below a plain +5% with the terms left where they were (+2.4%). Adding the claw‑back to a price rise makes the plan worse here, because both halves of it reach the shopper. Hold that against Step 7, where six points of premium mix earns almost the same money for a quarter of the volume.
Expected outcome: Contribution **$3.05M, +1.6%**; Brand Contribution **$2.25M, +2.2%**. Contribution Health **HEALTHY**. GTN Discipline **HEALTHY** (15.0%). Margin Safety improves to 46.2% (still HEALTHY). The Contribution Bridge shows a positive Price bar and a positive Trade Terms bar, swamped by a negative Volume bar much larger than Step 2 showed, with Mix, COGS, and Promo flat. Note the pair for comparison rather than for the plan: Step 7 builds the recommendation the other way round, by giving terms away instead of taking them.
Test the volume-recovery play and find the break-even elasticity
Reset all levers. Drag Price Change to -5%, the size of cut a brand reaches for when it is losing share. Volume rises to about 2.18M (up 9% from base on -1.8 elasticity, before any non‑price volume bonus). Read Contribution: about $2.88M, down 3.9%, and Brand Contribution $2.08M, down 5.4%. CRITICAL band. The price cut destroys contribution because elasticity is less elastic than the break‑even threshold. Break‑Even Elasticity uses the variable margin per unit as a share of net price, which is what the Margin Safety band reads, 42.1% at default (the same 42.1% the Contribution Margin tile shows, because both are struck before fixed costs). At a -5% price cut and 42.1% Margin Safety, the formula yields a 13.5% required volume gain, so the threshold elasticity is roughly -2.7. Anything more elastic than -2.7 self‑funds the cut. At -1.8 you are less elastic than threshold, so volume‑recovery on this SKU is not viable through pricing alone.
Expected outcome: Contribution **$2.88M, -3.9%**; Brand Contribution **$2.08M, -5.4%**. Contribution Health **CRITICAL**. The 'Scenario reduces contribution' warning fires below the lever panel. The Contribution Bridge shows a large negative Price effect, a large positive Volume effect, but the volume gain does not cover the price loss because the unit margin shrinks. Cross-reference with the **/tools/break-even-calculator** Tool for the BESC diagnostic on this scenario.
Run the COGS pass-through math on a 5% input cost shock
Reset all levers. Drag COGS Change to +5% (cocoa, packaging, energy inflation). Read Contribution: $2.83M, down 5.7%, and Brand Contribution $2.03M, down 7.8%. CRITICAL. Now add Price Change at +5% to test one‑for‑one pass‑through. Brand Contribution: about $2.10M, down 4.7%. CONCERNING band, partial recovery. The price lift recovers about 3 of the 7.8 points and the 9% volume loss eats the rest. Keep dragging Price and you will not get back to base: the best price‑only setting the slider will take is +8%, and it still reads 4.2% down. Now do the thing the room will ask for, which is to find the money on the customer. Add Trade Terms at -2pp on top of the +5% price. Brand Contribution moves from -4.7% to -4.6%. One tenth of one point, for two points of a structural rate you will spend the whole meeting defending, because what you collected on the invoice the retailer put back on the shelf. Try the deal plan next and it is a similar story: trimming Promo Depth peaks at -5pp and -4.0%, then turns around, reaching -9.0% at the floor with the calendar switched off. Even the mix only reaches -2.3% at its best six points. Nothing in the conventional kit closes a five percent cost shock on a SKU this elastic. What does close it is the shape of Step 7's recommendation, applied harder: +8% price, four points of terms GIVEN to the buyer, +6pp mix, Promo Depth -12pp and Frequency -15pp. That reads +1.4% and HEALTHY, above where you started before the cost went up. Watch it on the way, because the middle of that walk is ugly: giving the terms takes you to -10.0% and CRITICAL before the calendar cut turns it around.
Expected outcome: +5% COGS alone: Brand Contribution **-7.8%, CRITICAL**. Plus +5% price: **-4.7%, CONCERNING**. Adding Trade Terms at -2pp buys one tenth of a point, **-4.6%**, because the claw-back comes back at you through the shelf. Trimming Promo Depth peaks at -5pp and **-4.0%** before turning around to -9.0% at the floor. Six points of Premium Mix reaches **-2.3%** and no further. The plan that clears it is **+8% price, +4pp terms given, +6pp mix, depth -12pp, frequency -15pp**, at **+1.4% and HEALTHY**, and $50K of Brand Investment on top takes it to +2.0%. The lesson to carry into Step 7: on an elastic SKU a cost shock is not recovered from the customer's terms line, it is recovered by funding the customer properly and taking the money out of your own promotional calendar instead.
Spring the promo escalation trap and watch three health bands go red
Reset all levers. Drag Promo Depth to +15pp (total depth now 35%). Volume rises 2.0% and Brand Contribution reads about $1.87M, down 15.2% versus base, CRITICAL. The 'Promo depth above 25%' warning fires and Promo Intensity moves to HEAVY (score 50). Now drag Promo Frequency to +20pp (total frequency now 50%). Volume is up 4.5% and Brand Contribution reads about $1.31M, down 40.7% versus base, CRITICAL. Promo Intensity score = 35 + 25 = 60, which trips the EXCESSIVE band. GTN Discipline reads 28.5% and goes BLOATED, because the deal plan sits inside gross‑to‑net and now costs 17.5% of gross sales on its own, and Margin Safety drops to 32.8%, THIN. Half your volume on deal at 35% off buys about a twentieth more volume and destroys two fifths of brand contribution. Watch the volume line especially: the deeper the calendar goes, the less each extra point of discount buys, because the deal price is becoming the price shoppers expect to pay. This is the scenario associated with reference‑price erosion of 2 to 5% per event that tends to stick.
Expected outcome: +15pp depth alone: Brand Contribution **-15.2%, CRITICAL** (Contribution $2.67M, -11.2%), Promo Intensity **HEAVY** (score 50), GTN 21.5% and still HEALTHY. +15pp depth + +20pp freq: Brand Contribution **-40.7%, CRITICAL** (Contribution $2.11M, -29.8%), Promo Intensity **EXCESSIVE** (score 60), GTN Discipline **BLOATED** (28.5%), Margin Safety **THIN** (32.8%). Two warnings fire: the depth-above-25% warning and the contribution-loss warning. Frequency lands exactly on the 50% line, and the over-half-on-deal flag needs it to go past 50, so that one stays quiet. Cross-reference with **/tools/promo-mechanic-selector** (Tool #11) which shows that visibility-led mechanics outperform price-cut mechanics at every depth above 10%.
Build the plan, and find out the money was in the calendar all along
Reset all levers. Drag Premium Mix Shift to +10pp. Read the Volume tile before the Contribution one: 1.93M units, so 70,000 have gone, because you asked for ten points of premium mix and only the shoppers who follow the pack up pay the premium price. Brand Contribution reads about $2.25M, up 2.1%, HEALTHY. Walk the slider from 0 to 30 and the lift peaks near +7pp at about +2.6%, and is negative by +15pp. Six points is the setting that survives sitting next to everything else, so use that. Now the move most teams reach for first, and it is worth being wrong about early. Take Trade Terms to -4pp on its own, clawing four points of structural money back out of the buyer. Brand Contribution reads $2.19M, down 0.6%, CONCERNING, and the Volume tile reads 1.79M. You collected the money and it cost you more than it paid, because a claw‑back raises the invoice the retailer pays, they re‑mark the shelf on their new cost, and the shopper answers that higher price at your elasticity. Walk the slider and the whole claw‑back range is poor: -1.5pp is the best of a bad set at +0.6%, worth $12,489, and every point past about three turns it negative. So build the plan the other way round. Put Price Change at +4.5% and Brand Contribution reads $2.25M, up 2.3%. Now give the buyer four points: Trade Terms to +4pp. Brand Contribution falls to $2.11M, down 4.2%, CONCERNING, which is what the gesture costs before anything pays for it, and the reason nobody volunteers it. Add the six points of mix and you are at $2.16M, still 1.7% down. Everything so far has lost you money. Now cut the calendar. Promo Depth to -12pp takes you to $2.35M, up 6.8%, and Promo Frequency to -10pp takes you to $2.37M, up 7.5%, with Promo Intensity falling from MODERATE at 35 to LIGHT at 18. Two lever moves swung the plan by nine points of brand contribution. That money was sitting in a promotional calendar that was buying units you were largely selling anyway, rather than in the terms line everybody was arguing about. Finally, Brand Investment at $100K: $2.38M, up 8.0%, EXCELLENT, on 1.89M units. The cheque buys back volume at the rate both sides already charge, so it is the part of the plan the buyer has no reason to argue with. Why the plan stops at 4.5% and $100,000, because the sliders will tempt you past both. It is built to grow net sales by at least a point as well as profit, and that condition is what fixes the two settings. Take price to +7% and brand contribution reads +8.6%, better than the +8.0% here, with net sales down 1.4%. Drop the cheque to $60,000 and it earns $4,581 more and leaves net sales flat. Walk price and the cheque over their whole ranges and the best pair with no condition at all is +7.5% on a $60,000 cheque, worth $194,417, with net sales down 2.9%. Every one of those is more profit on a smaller business, and that is the plan an operating committee sends back, so hold net sales at +1% and +4.5% with $100,000 is the best pair there is.
Expected outcome: +10pp premium mix alone: Brand Contribution **$2.25M, +2.1%, HEALTHY**, Volume 1.93M, peaking near +7pp at +2.6%. Terms at -4pp alone: **$2.19M, -0.6%, CONCERNING**, Volume 1.79M, and the best claw-back anywhere on the slider is only -1.5pp at **+0.6%**. Building the other way: +4.5% price alone **+2.3%**; giving 4 points of terms takes it to **-4.2% CONCERNING**; adding +6pp mix reaches **-1.7%**; cutting Promo Depth 12 points reaches **+6.8%**; cutting Promo Frequency 10 points reaches **+7.5%** with Promo Intensity **LIGHT** (18). $100K of Brand Investment closes it at **$2.38M, +8.0%, EXCELLENT** on 1.89M units, with GTN Discipline **HEALTHY** (16.6%), Margin Safety **HEALTHY** (45.6%) and zero red bands. The recommendation to the operating committee: 'Take 4.5% on list price, give the buyer four points of structural terms, shift six points of mix to the premium pack, cut promotional depth by twelve points and frequency by ten, and put $100,000 behind the brand. Brand contribution is up $176,736, or 8.0%. Net sales are up 1.0%, and the retailer is $246,911 better off on their net margin.' Every figure on that line is the model's. Rehearse the giveaway clause before the meeting, because it is the one that draws the question. Four points of terms costs $174,288 standing on its own, and it is affordable only because the calendar cut paid for it. The plan is also built to grow net sales by at least a point, which is what holds price at 4.5% and the cheque at $100,000: +7% price reads **+8.6%** on net sales **down 1.4%**, and a $60,000 cheque earns **$4,581 more** on flat net sales. Both are more profit on a smaller business.

5.4Reading the output

Every KPI, the formula behind it, and how to interpret a positive or negative value.

KPI	Formula	How to read it
Contribution	Gross Profit minus Outbound Distribution ($0.34 a unit here, and it is only half of what variable cost means: cost of goods is the other half)	The headline number every commercial committee anchors to, struck before the $800K fixed block. The Brand Contribution tile beside it is the same number after fixed costs, and it is the line the 4-band Contribution Health readout grades, so its percentage moves are larger than the Contribution tile's on the same dollar change. Negative delta versus base means the scenario destroyed value. EXCELLENT at or above +8% lift; HEALTHY 0 to +8% is acceptable but unremarkable; CONCERNING -5 to 0% is recoverable; CRITICAL below -5% is value destruction.
Gross Margin %	Gross Profit / Net Sales x 100	The buyer's reading of your underlying cost economics. At the default 51.7%, struck before outbound distribution (the $0.34 a unit sits below it), the ratio moves with three things: cost of goods, the trade rates that set net sales, and the premium mix. A 5% cost shock takes it to 49.3%; taking 2 points of terms out lifts it to 52.8%. Compare it only with figures struck on the same basis, because a published margin that carries distribution inside cost of goods sits several points lower for the same business.
Net Price per Unit	Net Sales / Total Volume	The realization number every customer P&L review fights over. At default $3.56 against the $4.29 list price, you are realizing 83.0% of gross. Taking one point of structural terms back is worth $85,800 on the gross-to-net line, and two separate things then happen to the volume. The buyer withdraws support, because that point was holding listings and facings. And the on-invoice share of it comes off their bill, so their cost goes up and they re-mark the item, $5.99 to $6.02. Between them, volume falls 2.4% and net sales fall $89,879, while brand contribution rises only $10,548, because the units that stopped selling took their cost of goods and distribution with them. A 1% list-price rise is not the same trade. Your trade terms deduct 17% of it before you see it, so even with every shopper standing still it is worth $71,214, and at this tool's -1.8 elasticity enough of them walk that net sales fall $58,253 instead. On brand contribution the list rise is the better of the two here, $15,907 against $10,548, which is the opposite of what most planning meetings assume. Work both lines, and stop assuming the gross-to-net one is the cheap place to find money. Cross-reference with the Gross-to-Net Waterfall Tool for the full 5-layer cascade diagnostic.
Health bands	4 string-banded composites: Contribution Health (brand contribution delta vs base), GTN Discipline (% of gross sales), Promo Intensity (depth + freq/2), Margin Safety (unit margin / net price)	Each one reads on a 4-band scale calibrated to this calculator's mainstream FMCG yardstick. Read all four together. Two greens and two yellows means a healthy scenario with watch items. Any red means the scenario fails on one underlying dimension regardless of contribution headline. The CFO test: would the scenario survive if any single one of these was the only number on the table? If yes, the scenario is balanced. If no, the contribution lift is being bought from an underlying weakness somewhere else.
Volume	Annual Volume x (1 + price elasticity x price change %) x (1 + volume adjustment %), then the deal plan, trade terms and mix responses move it further	Volume is downstream of the price elasticity field, not a direct input. A +5% price change at -1.8 elasticity yields about -9% volume. The Volume Adjustment lever multiplies on top, so a +5% price plus +3% Volume Adjustment yields about -6% net volume. Use Volume Adjustment for non-price effects only: distribution gains, competitive dynamics, range expansion. Do not use it as a fudge factor to back out an elasticity assumption.

Read the right side of the calculator as a stack of three layers. Headline KPIs at the top tell you whether the scenario lifted or destroyed contribution and by how much. Health bands below tell you whether the lift is real (greens across the board) or borrowed from a weakness (a red somewhere). P&L Comparison Table below that lets you walk every line of the cascade and pinpoint where the delta came from.

The Contribution Bridge chart shows a floating waterfall from Base to Future contribution across six effect bars. The Price bar is the list move on base volume, net of the trade and promo rates that ride on list price. The Mix bar is the premium‑mix shift, and the Volume bar is the elasticity‑induced volume change at the true marginal contribution per unit. The COGS bar is the input‑cost lever on future volume, the Trade Terms bar is the terms‑rate change on future gross sales, and the Promo bar is the depth and frequency change on future gross sales. The bars telescope from Base to Future with no residual, so every dollar of the change lands in the bar of the lever that caused it. The Price Sensitivity chart on the right shows contribution and volume across the full -15% to +15% price‑change range with all other levers held at the current settings, so you can see whether you are close to the break‑even elasticity or well clear of it.

Use the Tool before you go to a customer JBP, an annual planning committee, or a finance review. Anchor every move proposed to a health‑band reading and a contribution delta. The committee will challenge the assumption (elasticity, COGS shock, mix shift) far more than the math, which is what the editable base case is for.

5.55 common mistakes to avoid

Diagnostic patterns that catch the most common misuse of this calculator.

Mistake 1Treating the textbook '1% price to +11.1% operating profit' as a rule of thumb at every elasticity
Symptom: The annual plan promised a 5% list lift on a -1.8 elasticity SKU and forecast a contribution lift of more than 50%, five times the textbook 11.1%. Actual landed at +2.4% versus base. The CFO challenged the math, the planning team blamed the model, and the credibility of the entire RGM cycle was undermined by a missing elasticity assumption.
Fix: **The +11.1% rule assumes inelastic demand and a different profit denominator.** At FMCG-realistic elasticities a 1% price lift delivers about +1.1% of brand contribution at -1.5, +0.7% at -1.8, and a small loss at -2.5, nowhere near 11.1%. Use the calculator's actual scenario response, not the textbook headline. Price and terms together do not reach the bar either, and they do not even beat price on its own. On this SKU, +3% price with -2pp trade terms lifts brand contribution about 1.9%, and +5% with -2pp about 2.2%. Moving list price alone and leaving the terms where they are gets you +2.6%. Reaching EXCELLENT takes a premium mix shift and a cut to the promotional calendar, and it is those two that make it affordable to give the buyer terms rather than claw them back, which is the walk Step 7 makes.
Mistake 2Modeling levers in isolation when interaction effects dominate
Symptom: The trade plan moved Price up 3%, Trade Terms up 2pp, Promo Depth up 5pp, and Premium Mix up 5pp simultaneously. The two positive single-lever readings, +1.8% for the price and +2.4% for the mix, were the ones quoted in the approval; the 2pp of terms (-2.6% on its own) and the 5 points of depth (-4.8%) were waved through as customer investment. The combined scenario landed at -2.9%, CONCERNING, with Promo Intensity tipping into HEAVY. Note that the four readings do not simply add up, and they rarely do: the terms and the deal plan are both supplier money in the same customer margin, so the retailer's response answers to the two together rather than to each in turn.
Fix: **Test combined moves as a single scenario before approving the trade plan.** The Tool's lever interactions are non-linear and asymmetric. A price lift shrinks the volume a mix gain lands on. A trade-terms cut lifts the net price your remaining volume earns and costs distribution at the same time, and a deeper promo raises the gross-to-net rate on every unit. Use the calculator to model the full simultaneous combination rather than the sum of the single-lever lifts, and read the negative levers as carefully as the positive ones.
Mistake 3Pursuing volume recovery with price cuts on elastic SKUs
Symptom: The brand lost 4 share points over two quarters and the response was a -5% price cut as a defensive move. Brand contribution dropped 5.4% in the next quarter. Sales blamed retailer execution, but the math was fundamental: at -1.8 elasticity and 42.1% margin per unit (the Margin Safety reading), the break-even elasticity for a 5% cut is roughly -2.7. The brand was less elastic than threshold; the cut destroyed contribution mathematically.
Fix: **Compute Break-Even Elasticity before any defensive price cut.** Required volume gain = the price cut divided by (margin per unit as % of net price, minus the price cut). The break-even elasticity is that gain divided by the cut. At 42.1% Margin Safety and a -5% cut, the formula yields a 13.5% required volume gain, so the break-even elasticity threshold is roughly -2.7. Any actual elasticity less elastic than -2.7 means the cut destroys contribution. Cross-reference with the **/tools/break-even-calculator** Tool for the full Break-Even Elasticity diagnostic. Defensive responses on elastic SKUs usually need to come through a shallower deal plan or a premium-mix lift rather than a price cut. They rarely come through clawing trade terms back, because the on-invoice share of those terms reaches the shelf and puts your own ticket up.
Mistake 4Assuming a cost rise can be passed straight through on price
Symptom: Procurement signaled a 5% COGS inflation and the plan responded with a +5% list price one-for-one pass-through. The customer accepted the list move. The next quarter, brand contribution landed -4.7% versus base, because the 9% volume loss from the elasticity response took back most of what the price gain had recovered.
Fix: **One-for-one pass-through does not cover a cost shock at the default elasticity.** A 5% COGS shock with +5% price still leaves brand contribution 4.7% below base on the default biscuit SKU. No price-only setting gets it back either: the best is +7.9% list, still 4.2% down. Reaching for the customer's terms line buys almost nothing. A +5% list move with -2pp of trade-terms recovery takes you from 4.7% down to **4.6% down**, one tenth of a point, because what you collect on the invoice the retailer puts back on the shelf ticket. Trimming the deal plan on top peaks at -5pp and 4.0% down before it turns around on you. The combination that does clear it runs the other way: **+8% list, four points of terms given to the buyer, +6pp of premium mix, and the calendar cut hard (depth -12pp, frequency -15pp)**, which lands 1.4% above base. Fund the customer properly and take the money out of your own promotional calendar, rather than trying to take it out of their margin.
Mistake 5Settling for a HEALTHY contribution band when EXCELLENT is reachable
Symptom: The annual plan landed at +0.6% brand contribution versus base (two points of terms recovered, nothing else), all four health bands green or amber, and the operating committee signed off on it. The same SKU was capable of **+8.0%**, worth **$176,736** against base and **$164,567** against the plan that was signed. Nobody proposed it, because it starts by giving the buyer money: +4.5% list, four points of structural terms handed over, six points of premium mix, the deal calendar cut twelve points of depth and ten of frequency, and $100,000 put behind the brand. Note what is doing the work on that list, because it is the lever the meeting treats as untouchable. The two calendar cuts are worth nine points of brand contribution between them. Without them the give-back is unaffordable and the whole plan sits at -1.7%. That plan also grows net sales 1.0%, which is the condition it is built to: more profit on a shrinking business reads better on one tile and loses the room.
Fix: **A scenario in the HEALTHY band, 0 to +8%, is acceptable and unremarkable. EXCELLENT is what justifies the planning effort.** A scenario in the HEALTHY band (0 to +8% brand contribution lift) is acceptable but unremarkable. EXCELLENT (at or above +8%) is the band that justifies the planning effort. Run combined-lever scenarios systematically: every annual plan should test (a) base, (b) cost-recovery if applicable, (c) margin-expansion play, (d) deal-plan retune, (e) premium-mix lift, (f) full combined. The CFO test: does the recommendation sit in EXCELLENT on Contribution Health while keeping the other three health bands in green or yellow? If not, you are leaving margin on the table.
