Retail & Consumer Goods: Pricing and Promotional Strategy Cases

Pricing and promotional strategy cases represent roughly 25% of all retail and consumer goods engagements at top consulting firms. These cases test whether you can connect pricing decisions to margin impact, customer behavior, and competitive dynamics — skills that separate strong candidates from average ones.

Why Pricing Cases Dominate Retail Consulting

Retail operates on thin margins — typically 2–5% net margin for grocers and 8–12% for specialty retailers. A 1% improvement in pricing realization often delivers more profit impact than a 3% increase in volume. This is why consulting firms dedicate entire practice areas to retail pricing, and why interviewers love testing candidates on these dynamics.

Based on our analysis of 800+ consulting case interviews, retail pricing cases cluster around three scenarios: everyday pricing architecture, promotional effectiveness, and markdown optimization. Each requires a distinct analytical approach.

The Retail Pricing Strategy Spectrum

Every retailer positions somewhere on the pricing spectrum between Everyday Low Price (EDLP) and High-Low pricing. Understanding where your case client sits — and whether they should shift — is the first analytical step.

The strategic decision framework for evaluating pricing architecture:

Trade Spend and Promotional Effectiveness

In consumer goods, manufacturers spend 15–25% of gross revenue on trade promotions — the second-largest line item after cost of goods sold. In our experience working with CPG clients, roughly 40–60% of this spending generates negative ROI. This makes trade spend optimization one of the highest-impact areas for consulting engagements.

Key Metrics for Promotional Analysis

When you encounter a promotional effectiveness case, structure your analysis around these metrics:

The Promotion P&L Framework

For any promotional case, build a promotion-level P&L:

1. Gross uplift volume — total additional units sold during the promotion window
2. Subtract cannibalization — volume shifted from adjacent products in the portfolio
3. Subtract pull-forward — demand borrowed from future periods (measure by post-promotion dip)
4. Net incremental volume — true new demand generated
5. Apply net margin per unit — not gross margin, since promotions often carry additional costs (displays, advertising, logistics)
6. Compare to total promotion investment — trade funding + retailer markdown + incremental supply chain cost

Markdown Optimization Cases

Markdown cases typically involve a retailer sitting on excess inventory — seasonal merchandise, end-of-life products, or slow-moving SKUs. The analytical challenge is balancing sell-through speed against margin preservation.

Based on our analysis, retailers that implement data-driven markdown optimization typically recover 200–400 basis points of annual gross margin versus rules-based approaches (e.g., “take 30% off after 8 weeks”).

Markdown Decision Framework

Structure markdown cases around three variables:

• Remaining shelf life — weeks until the product becomes unsellable or the selling season ends
• Current sell-through rate — weekly units sold at current price point
• Price elasticity at markdown — how much volume accelerates at each price reduction tier

The optimal markdown cadence maximizes total margin dollars across remaining inventory, not margin percentage on any single unit.

How to Structure a Retail Pricing Case

When you receive a retail pricing case in an interview, apply this structured approach:

1. Clarify the objective — is the client trying to grow revenue, protect margin, respond to a competitor, or liquidate inventory?
2. Map the competitive context — where does the client sit on the EDLP-to-High/Low spectrum relative to key competitors?
3. Segment the assortment — not all products deserve the same pricing logic; separate known-value items (KVIs), traffic drivers, and margin builders
4. Quantify price elasticity — even rough estimates of volume sensitivity matter for structuring recommendations
5. Build the economic model — connect pricing changes to margin impact using contribution margin analysis
6. Pressure-test with competitive response — will competitors match? How quickly?

Common Pitfalls in Retail Pricing Cases

In our experience coaching candidates, these errors appear repeatedly:

• Ignoring cross-elasticity — a price cut on Coca-Cola affects Pepsi volumes in the same store; always consider portfolio effects
• Treating margin percentage as the objective — retailers care about margin dollars per linear foot of shelf space, not percentage
• Forgetting the shopper mission — a price-sensitive grocery trip differs from a convenience purchase; context determines elasticity
• Assuming uniform elasticity — premium shoppers and value shoppers respond differently to the same percentage discount
• Neglecting supplier economics — in many retail categories, the manufacturer funds 50–70% of promotional discounts

Key Takeaways

• Retail pricing cases test your ability to connect pricing decisions to overall margin impact — not just unit economics
• The EDLP vs. High-Low spectrum is your first diagnostic tool; determine where the client sits and whether their position is sustainable
• Trade spend represents 15–25% of CPG gross revenue, with 40–60% generating negative ROI — this is a massive optimization opportunity
• Always decompose promotional lift into gross uplift, cannibalization, pull-forward, and true incrementality
• Markdown optimization is about maximizing total margin dollars across remaining inventory, not protecting margin rate
• Structure pricing cases by clarifying the objective, mapping competition, segmenting the assortment, and building an economic model
