Price Elasticity of Demand
Understanding how price sensitivity determines whether a price change makes or loses money
A 1% price rise lifts profit more than three times as much as a 1% volume gain.
Of every lever a commercial team can pull, price drops to the bottom line hardest. Across a 2,463‑company benchmark (Marn and Rosiello), a 1% rise in realized price lifts operating profit by about 11%, before a single unit of volume moves. The same 1% found in variable cost is worth less, a 1% volume gain less still, and a 1% cut in fixed cost least of all. Price stays top and fixed cost stays bottom whatever your cost structure, though the middle two swap over once gross margin passes 50%, where a point of volume starts to beat a point of variable cost. Depending on that structure the profit swing runs from roughly 7% to 15%.
That leverage cuts both ways. For a brand on a 42% margin, a 1% price cut has to pull back about 2.4% more volume just to stand still, and demand rarely delivers it. Losing customers is easier than winning them back, so a cut wins less volume than the matching rise gave away. A price rise often pays where the mirror‑image cut would only lose money.
One number decides which way any move breaks: price elasticity of demand, the percent of volume you give up for each 1% you add to price. It is not a fixed constant. It bends with the price point you sit at, the size of the move, and even its direction. The concept cards below take it apart, and the sandbox lets you feel it.
What a 1% improvement in each lever does to operating profit
Price is the strongest lever by a wide margin. Averages across the same 2,463-company benchmark. Your own figures move with your cost structure: price stays top and fixed cost stays bottom, but volume overtakes variable cost once gross margin passes 50%.
Price Elasticity of Demand
Price elasticity of demand is the percent change in volume for each 1% change in price. An elasticity of -2.0 means a 1% rise costs you 2% of your volume. Whether the move helps or hurts turns on where that number sits against 1.0: above 1.0 the brand is elastic and a price rise shrinks revenue, below 1.0 it is inelastic and a rise grows revenue. Revenue is only half the story, though, because the profit outcome turns on your margin, so even an elastic brand can make money on a price rise.
E = percent change in volume / percent change in priceAcross more than 1,800 published estimates, the average brand-level elasticity is about -2.6 (Bijmolt and van Heerde): the typical branded product loses 2.6% of volume for a 1% price rise. That average hides a sevenfold spread, from about -0.5 on household essentials to -3.5 on soft drinks. Your job is to know where your brand sits, and to remember that demand moves asymmetrically: a price rise loses more volume than an equal cut wins back. How that volume swing lands on the bottom line is the work of the Integrated RGM.
What you'll take away
Price is the highest‑leverage line on your P&L. A 1% rise in realized price adds more operating profit than a 1% volume gain or a 1% cost cut, by a wide margin.
Price elasticity is the one number that decides whether a move pays: the percent of volume you give up for each 1% you add to price.
Judge a price move on profit, not revenue. A rise can shrink turnover and still grow the bottom line, because your margin sets the outcome.
Demand is asymmetric. A price cut rarely wins back the volume an equal rise gave away, so a rise is usually the safer move.
Elasticity is not one fixed number. It shifts with the price level, the size of the move, its direction, and the demand model you fit.
Master these pricing concepts before exploring the simulator
22 concepts- Purpose
- Simulate how price sensitivity (elasticity) determines whether a price change makes or loses money for a biscuit brand.
- How to use
- Set elasticity and pass-through on the left panel, then drag the price slider to see volume, revenue, and gross-profit curves respond in real time. Take your scenario to the AI Strategist strip below for live commentary.
- What to watch
- On the default log-linear model there is no revenue peak to hunt for. Revenue slides down as price rises whenever elasticity sits past -1.0, and at exactly -1.0, with full pass-through, it flattens out completely. Gross profit is the curve with a peak, and at the opening cost, elasticity and pass-through it lands on $6.05. That peak is conditional, which is the part most people miss: it exists only while your elasticity is past -1.0, and it slides off the top of the chart as you walk elasticity back toward -1.0 or drop pass-through below about 76%. Switch the model to Linear and revenue finally traces the classic inverted U, peaking below the profit peak by exactly half your unit cost. This is the core insight Lesson 8 builds on.
Controls
CrunchField 300g, Hero SKU
Flagship biscuit SKU. Base price $4.29, unit cost $2.49, volume 2.00M units/month, a gross margin of 42.0%. At roughly $103M in annual revenue, this is a top-tier performer. The kind of SKU where a 1% price decision is worth seven figures a year.
The shelf price consumers see. Higher prices increase margin per unit but risk losing price-sensitive shoppers.
How sensitive demand is to the price shoppers see on shelf. The default -1.7 matches the CPG working ceiling for established brands; most brands with meaningful equity sit in the -0.8 to -2.0 zone. Slide toward -2.62 to stress-test against the meta-analytic average, or to -3.5 to model a value product with many close substitutes. Anything shallower than -1.0 and your brand has no profit-maximizing price at all, which the Optimal price overlay will show you. See the Calibrating Your Elasticity Estimate concept card for the reference points every pricing manager should know.

How much of your wholesale price change reaches the shelf? 100% = full pass-through.
How much input costs have risen, applied in one shot to today's $2.49 unit cost (new cost = $2.49 x (1 + rate)). The presets trace the 2021 to 2026 story: 3% a normal year, 6% the CFO's cost-recovery case, 8% steeper, 15% a 2022-style shock, 25% the documented worst case for a food manufacturer. Inflation on its own moves no volume, so watch the margin and profit tiles, not the volume tile, until you change price.
Demand, Revenue and Gross Profit
Volume reads off the left axis, revenue and gross profit off the right. On the log-linear model revenue never turns over: it slides down when demand is elastic, sits dead flat at exactly -1.0, and climbs when demand is inelastic. Gross profit is the curve with a peak, but only while |E| is above 1. Walk the elasticity slider up toward -1.0 and watch that peak slide right and off the chart.

The Elasticity Reality Check
You are the pricing manager for CrunchField, an established biscuit brand with 12% category share. Your 200g pack sells at $3.49 with weekly volume of 48,000 units. The CFO wants a cost-recovery price increase, but your sales director warns of volume loss. You have scanner data and need to use elasticity analysis, grounded in strategic pricing principles, to determine whether the increase will help or hurt the P&L.
CrunchField raised its price from $3.49 to $3.69 and weekly volume dropped from 48,000 to 43,200 units. What is the point elasticity of demand (to one decimal place)?
You now know that elasticity tells you how much volume a price change costs you. The question your CFO and your sales director actually need answered is the next one: how much volume can you afford to lose before the move destroys gross profit? That threshold has a name, the Break-Even Volume Change, and the elasticity sitting exactly on it is the Break-Even Elasticity. Read it in the direction you are moving, because the test flips. On a price RISE the move pays when your demand is shallower than the break-even, since you keep enough of the volume to bank the extra margin. On a price CUT it pays only when your demand is steeper than the break-even, because a cut has to buy back the margin it gave away, and only genuinely elastic demand delivers enough volume to do that. Getting that direction backwards is how a pricing committee talks itself into a discount that loses money for a year before anyone notices. You will lean on this test more than almost any other number in the course. Next up: the math behind it.
