Pricing Cases: Four Questions to Ask Before Any Framework

Pricing cases look simple. The prompt says something like "our client sells a product for $20; should it raise the price?" and the temptation is to reach for a formula: unit cost plus a margin, or "what do competitors charge?" Both of those are inputs, not answers. Candidates who stop at either one usually have not thought about the one thing that decides a pricing question, which is how customers will behave.

Strong candidates slow down for a minute and ask a few questions that determine which analysis matters. This post lays out four of them, the three standard approaches to setting a price and when each fits, a worked example that shows revenue and profit side by side, and the mistakes interviewers see most.

Why pricing cases trip people up

A price change moves two things at once. It changes what you earn on each unit, and it changes how many units you sell. Candidates usually analyze one of those and forget the other. The second reason is that the volume response cannot be computed from the prompt. It is a judgment about customers, so your answer will be graded on how clearly you state your assumptions and how you would test them.

The four questions

1. What is the objective?

Maximizing profit is the default, not the only possibility. A company entering a market may want share. A premium brand may be protecting its positioning. A business with excess inventory may want to clear it, and one facing a new entrant may be trying to keep customers. The objective changes the right price, so ask: "Is the goal to maximize profit, to grow share, or something else, and over what time horizon?"

2. Who are the customers, and how do they differ in willingness to pay?

Customers are not one number. Business buyers and consumers, heavy users and occasional ones, people who compare prices and people who pay for convenience, one region and another: each group may value the product differently. Ask: "Are there distinct customer segments, and does the client charge them differently today?" The answer tells you where there may be room to raise price, and where demand is likely to be most sensitive.

3. What do cost, competitors, and customer value say?

These give you three anchors:

• The cost floor. Variable cost per unit. Below it, each sale loses money, unless there is a strategic reason to accept that.
• Competitor anchors. What comparable products and substitutes cost. These are the prices your customers compare against.
• The value ceiling. What the product is worth to the customer: time saved, revenue earned, or the cost of the next-best alternative. Above this, they do not buy.

The price usually sits between the floor and the ceiling, and where it sits depends on how differentiated the product is. Ask: "Do we know the unit cost, the main competitors' prices, and any evidence on how customers value the product?"

4. What happens next?

A price change triggers responses. Some customers leave or buy less. Some trade down to a cheaper product in the client's own range, which is cannibalization. Competitors may match or ignore the move. The price can also change perception: a rise can signal quality or break trust, and customers often anchor on the old price. Ask: "How have customers responded to past price changes, and how have competitors reacted?"

Three ways to set a price

Cost-plus

Add a margin to unit cost. It is simple, it is designed so that each sale covers its allocated costs at planned volume, and it is common where costs are transparent or customers expect it, such as custom work. But it ignores customers entirely. It can leave money on the table when customers would pay more, and it can price you out when they would not. Use cost as a floor, not an answer.

Competitor-based

Match, undercut, or price at a premium to rivals. It reflects what customers compare against and fits products that are close to interchangeable. It assumes the offerings are similar, it says nothing about your own value, and a policy of always undercutting invites a price war.

Value-based

Price in proportion to the value delivered to the customer. It can capture the most, and it suits differentiated products and business customers whose return on the purchase can be measured. It is also the hardest to do, because you need real insight into what customers gain. In an interview, you can propose how you would estimate it, such as customer interviews or a comparison with the cost of the alternative.

In practice the three work together: cost as the floor, competitors as the reference, value as the ceiling. The objective from question one decides where in that range you aim.

Segmentation

If customers differ in willingness to pay, a single price either loses the high-value customers' surplus or loses the price-sensitive ones entirely. Segmenting charges different groups different prices through versions (basic and premium), timing (early-purchase or off-peak pricing), volume discounts, or channel. It works when the groups genuinely differ, when you can keep them apart so that high-value buyers cannot simply take the cheaper option, and when the differences will not feel unfair.

Worked example: a 10 percent price increase

Build the before and after, and compute profit, not just revenue:

The arithmetic: before, revenue is 100,000 × $20 = $2,000,000; variable cost is 100,000 × $12 = $1,200,000; contribution is $800,000, or $8 a bag. After, volume is 92,000 bags at $22, so revenue is $2,024,000; variable cost is 92,000 × $12 = $1,104,000; contribution is $920,000, or $10 a bag. Fixed costs do not change, so profit goes from $800,000 − $500,000 = $300,000 to $920,000 − $500,000 = $420,000.

Look at what a revenue-only analysis would have said: revenue is up barely more than one percent, which sounds like a wash. Profit is up 40 percent, because the bags you no longer sell also carry costs you no longer pay. That gap is the point of the exercise.

Turn it into a decision rule

The 8 percent is the sales team's guess. Rather than defend it, compute how much volume the company could lose before the price rise stops paying. At the new price the contribution per bag is $10. To match today's $800,000 of contribution, the company needs $800,000 / $10 = 80,000 bags, a 20 percent drop from 100,000. As a shortcut: the break-even volume loss equals the price increase divided by the price increase plus the contribution margin. Here the contribution margin is $8 / $20 = 40 percent, so the figure is 10 / (10 + 40) = 20 percent.

Compare the two numbers: the forecast loss is 8 percent and the break-even loss is 20 percent, so there are 12 percentage points of cushion. Put another way, an 8 percent volume loss on a 10 percent price rise is an implied price elasticity of about −0.8; demand that inelastic is why revenue rises. The break-even loss of 20 percent corresponds to an elasticity of −2.0. The direction of the rule is worth noticing as well. The higher the margin, the less volume loss a price rise can absorb, because each lost unit costs more contribution. At an 80 percent contribution margin, the same 10 percent increase breaks even at a loss of 10 / (10 + 80), about 11 percent.

What changes for a new product

With no sales history, the same four questions apply, but you lean harder on the anchors. Competitor prices and the value to the customer matter more, and cost tells you the floor. Propose a way to test: a limited launch, customer conversations, or a few price points in different markets. The market entry post covers where pricing fits in an entry case.

Common mistakes

• Defaulting to cost-plus and stopping. It ignores two of the three anchors and says nothing about how customers will react.
• Analyzing revenue instead of profit. As the example shows, the two can tell different stories.
• Ignoring the volume response. Treating demand as fixed makes every price rise look like free money.
• Treating all customers as one. A single average hides the segments that matter.
• Using the wrong cost. For a volume decision, use variable cost. Fixed costs do not change when volume does.
• No decision rule. "It depends on how customers react" is true and useless. "It pays up to a 20 percent volume loss" is something you can act on.

The price-times-volume decomposition above is the same logic as the revenue branch of a profitability tree. If that structure is still fuzzy, the full profitability walkthrough shows it applied to a case from prompt to recommendation.
