Pricing found the optimal price for one pack. PPA begins where Pricing ends: real portfolios have many packs, many tiers, and many channels. The Zone of Indifference (plus or minus 1 to 5%) from Lesson 8 is the reason tiers must differ by at least 5% in NSV/kg to register as distinct; the -2.62 meta-mean elasticity from Lesson 1 is the reason a small mix shift upward translates to disproportionate operating profit. Every PPA lesson will reuse these calibrations, starting with price tiers, which are the structural skeleton of every category.

The Hook

The core tier holds 50% of volume. The premium tier holds 2%. Guess which one is growing.

A leading frozen foods company's internal price tier analysis revealed a category where the Core tier (price index 95-105) held 50% of volume but was declining at -0.5% per year. Meanwhile, the Super Value tier (<85 index) was growing at +4.0% and the Upper Core/Better tier (105-115) at +8.0%. The entire competitive landscape was shifting underneath them, and they only saw it when they mapped the tier structure. Every PPA decision starts with understanding which price tiers exist, how big they are, and where the growth is moving.

Upper Core tier annual growth+8.0%
Volume Share %Value Share %
1.2%0.5%1.8%8.0%3.2%

The price tier ladder shows volume share and growth rate by tier. The core tier holds the most volume, but the upper tiers are growing fastest. That's where the margin opportunity lives.

Key Concept

Price Tier Architecture: The Category's Hidden Structure

A price tier ladder, built on RSP/kg indexing with the core tier as baseline (index 100), reveals the structural reality of any category. A common industry framework uses five tiers: Super Value (<85), Good/Value (85-95), Core (95-105), Upper Core/Better (105-115), and Premium (>115). Volume share tells you where consumers are; value share tells you where the money is.

In one company's analysis, the Upper Core tier held only 10% of volume but was growing at +8.0%, faster than any other tier. Without tier mapping, they would have missed both the threat and the opportunity. The 5Cs landscape assessment begins here, with price tier structure as the category's diagnostic foundation.

The Sandbox
How this sandbox works
Purpose
See how shifting volume across five price tiers drives blended portfolio margin and value share. The core mechanic behind premiumisation versus the value trap.
How to use
Drag tier volume sliders to allocate share across Economy, Mainstream, Mid-Premium, Premium, and Super-Premium; other tiers rebalance automatically. Click a tier name to inspect its price, margin, and value contribution.
What to watch
Blended margin and value share rarely move in proportion to volume. Small shifts from Mainstream to Mid-Premium often pay back far more than equal shifts elsewhere. Find where the portfolio actually earns its money.

Frozen Category Tier Strategy

You are the RGM analyst at a major frozen food company reviewing the price tier landscape. Internal data shows five tiers (Super Value, Good/Value, Core, Upper Core/Better, Premium/Best) with distinct growth trajectories and market share concentrations. The commercial director wants a tier strategy recommendation for next year's planning cycle. Use the tier benchmarks and your understanding of price indexing to answer these questions.

Your frozen food category has five price tiers indexed to the Core tier (RSP/kg index 100). The data shows: Super Value (<85 index) holds 30% volume and is growing at +4.0%. Core (95-105) holds 50% volume but is declining at -0.5%. Upper Core/Better (105-115) holds 10% volume and is growing at +8.0%. What is the most strategically important finding?

The Bridge

Tiers Are the Skeleton. Pack Roles Are the Muscle.

This lesson mapped the structural terrain of a category: the 5-tier landscape, RSP/kg indexing, tier growth trajectories, the Zone of Indifference floor (plus or minus 5% minimum gap) from Pricing Lesson 8, the Van Westendorp PSM validation step from Lesson 3, and the White Space Value Formula for sizing tier entry. You now know where volume sits, where value concentrates, and why the same 5% mix shift from Core to Upper Core is worth roughly the same operating profit as a 1% price increase on the whole portfolio. The 8.7% operating profit leverage from Lesson 2 is captured through NSV/kg rather than shelf price.

Here is what tier analysis alone cannot answer: within the Core tier, which pack is fighting what battle? A 10-piece fish-fingers pack at RSP/kg index 88 and a 15-piece at index 100 both sit in "Core" but they perform very different strategic jobs. The first recruits constrained shoppers at an affordable total price; the second is the weekly household repeat purchase. Assigning the wrong job to a pack, or leaving a job unfilled, is a portfolio error that no amount of pricing optimisation can compensate for.

The four pack roles each play a distinct part. Entry (RSP/kg index around 120 or above, absolute price under the affordability threshold), Routine (index 100, the anchor baseline), Upsize (index 70-85, rewards loyalty with per-kg savings), and Upscale(index >120 on per-kg, premium format). Each has its own target shopper segment (the Constrained / Cautious / Unrestricted framework you met in the 5Cs concept card), its own promotional intensity rule, and its own margin contribution profile. The Pack Roles Health Check is the single most diagnostic tool in PPA. That is next.
