Pricing cases: three ways to price, and how to choose one out loud

Cost-plus, competitor-based and value-based are not a ranking. The case is won by picking the method the situation actually supports and putting a number behind it. Worked dialogue and a drill.

The short version
  • Cost is the floor, competitors are the anchor, value is the ceiling. Touch the first two in a clause each and spend the case on the one that binds.
  • Value-based pricing without a number is a slogan. Turn the buyer's saving into money per year and over the life of the product.
  • Subtract what the seller gives up before taking a share of it. A product that removes a consumable you sell can raise the unit price and lower lifetime profit at the same time.
  • Always attach the volume consequence. The break-even volume loss turns an argument into a threshold.

There are three ways to set a price. What does it cost us and what margin do we want. What do competitors charge. What is it worth to the buyer.

Most candidates have heard that the third one is the sophisticated answer, so they say "value-based" early and confidently and then cannot produce a number for the value. That is worse than starting with cost, because it looks like vocabulary rather than analysis.

The three methods are not a ranking. They are three lenses. A strong answer touches the floor and the anchor in a clause each, spends the case on the one that actually binds, and does the arithmetic for that one.

Pick the method from the situation

Cost-plus is a floor, not a price. It tells you what you cannot go below without losing money on every unit, which is genuinely useful and takes ten seconds. It tends to be the answer only where you have no other lever, which mostly means commodities, regulated pricing and cost-plus contracts.

Competitor-based is the right anchor when the product is substitutable and the buyer can see the alternatives side by side. It is also the right anchor when you are entering someone else's market, because your price is a message about where you intend to sit.

Value-based is the right method when you can name what the buyer gets in money. If the product saves a customer a measurable amount, or earns them a measurable amount, the price can be set as a share of that. If you cannot quantify the value, you do not have value-based pricing, you have an opinion.

Name the floor and the anchor in a clause each, then say which one binds and why it binds here. "Cost gives me a floor and competitors give me an anchor, but the number that decides this is what the maintenance event is worth to the customer, because that is a cost they already budget for" takes eight seconds and is about this product. What loses the room is announcing the three as a method and then working through them in order, which is the framework move in a different costume.

Value-based pricing needs a number

This is the step candidates skip. The value to the buyer has to become an amount, and there are only a few honest routes to it.

What they pay today. For a replacement product, the incumbent's total cost of ownership is the reference. Not just its price, but the labor, downtime and consumables around it. Check who collects that spend before you count it as value you can charge for. If the consumable the new product eliminates is your own revenue, you are not creating value worth a third of, you are moving money from one of your lines to another and asking to be paid for the trip.

What they earn or save. If the product raises throughput 10 percent, the value is 10 percent of the margin on that throughput, per year, for as long as it lasts.

What the next best alternative costs. Including doing nothing, which is always an option and is often free.

Then set the price as a share of that value, and say the share out loud. A third is a useful working default rather than a rule: it leaves the customer an obvious reason to buy and it is easy to defend as a starting position you would adjust. Push higher when switching costs are high or the alternative is genuinely poor, lower when the buyer has real options or the benefit arrives slowly. What is not defensible is capturing 90 percent, which is arithmetically possible and commercially fictional.

What this sounds like

InterviewerOur client makes industrial water filtration systems. They have developed a new unit that lasts twice as long as the current one before the filter has to be replaced. What should they charge for it?
CandidateThe thing that makes this specific is that we are not selling a better machine in the abstract, we are selling the removal of a maintenance event that the customer currently budgets for and we currently bill for. So cost gives me a floor and competitors give me an anchor, but the number that decides this is what that maintenance event is worth to the customer and what it is worth to us. Before I size either, what does the current unit sell for, and what does the customer spend on replacement filters?
InterviewerThe current unit sells for 10,000 dollars. Customers replace filters twice a year at 1,000 dollars each, plus roughly half a day of maintenance labor per replacement.
CandidateLet me say what I expect before calculating. If we halve the replacement frequency, the customer saves one filter and one maintenance visit a year. The filter is 1,000 and the labor is half a day, so the annual saving should land somewhere near 1,300, and over a unit life of, say, seven years that is roughly 9,000 undiscounted. I will assume a seven-year life and a fully loaded maintenance day of 600, and I would want both checked. Shall I run it?
InterviewerGo ahead.
CandidateOne filter at 1,000 plus half a day at 600, so 300, gives 1,300 a year. Times seven years is 9,100. Discounting roughly, call the present value about 7,200.
InterviewerSo what do you charge?
CandidateBefore I answer that, I want to check one thing, because I think it changes the answer. Those filters are our revenue. We are not just saving the customer 1,300 a year, we are giving up 1,000 a year of our own filter sales per unit. Do we know the margin on a filter?
InterviewerGood question. Filters run at about 70 percent contribution margin.
CandidateThen let me do the arithmetic that decides this. We lose one filter a year at 1,000 of revenue and 70 percent margin, so 700 a year of our own profit, for seven years. That is 4,900 undiscounted, and applying the same rough factor I used on the customer side, call it 3,900 today. So the bar is not zero, it is a price increase above 3,900. A third of the customer value was about 2,400. Half was about 3,600. Both of those leave us worse off than doing nothing.
InterviewerSo the product is a mistake?
CandidateNot necessarily, but it cannot be priced off customer value alone. Three ways out, and I would want to test them in this order. Price it around 14,500, which clears the 3,900 with a little left over, and accept that we are asking for a 45 percent premium and will lose some volume. Keep the filter economics instead by making the longer-life filter proprietary and priced higher, so we sell one at 1,800 rather than two at 1,000, which costs us only 140 a year of margin instead of 700 and leaves the customer better off too. Or treat it as a defensive launch, price it near 13,000, and accept slightly lower lifetime profit per unit because a competitor will bring this to market anyway and we would rather cannibalize ourselves.
InterviewerWhich would you recommend?
CandidateThe second, and priced concretely: the unit at 11,500 and the proprietary filter at 1,800. The unit uplift of 1,500 more than covers the 775 of filter margin we give up over the life, so we are ahead per unit, and the customer still saves about 500 a year against their 2,600 today, so the sale stays easy. That last part matters because it is the option with almost no volume risk. At 14,500 I would want to know our unit cost and our break-even volume before committing, and at a 45 percent price rise on a 40 percent contribution margin we could only afford to lose about half our volume before it stops paying, which sounds like a lot until you remember procurement has to approve the increase.
InterviewerAnd what would stop you?
CandidateTwo facts. Whether the filter can actually be made proprietary, which is an engineering and legal question rather than a pricing one. And what the closest competitor charges for a comparable unit, because if they are already at 13,000 then our 10,000 was underpriced to begin with and the whole conversation changes. What I would not do is take the 12,400 that a naive value calculation produces, because that number quietly assumes our own consumable revenue is free.

That dialogue is worth reading twice, because the naive value answer and the right answer are different. Capturing a third of the value the customer receives is the standard opening move, and here it destroys profit, since a large part of that value is money the client was collecting themselves. The candidate found it by asking what the price change breaks elsewhere before naming a price rather than after.

The volume question you cannot skip

A price is only half a decision. The other half is what happens to volume.

You do not need a formal elasticity to handle this in a case. You need to ask the question and reason about direction and rough magnitude. If we raise price 10 percent and lose 5 percent of volume, at a 40 percent contribution margin we are clearly better off. If we lose 25 percent of volume, we are not. Contribution margin is the one to use here, not operating margin, because the fixed costs do not move with the units you lose.

The break-even volume loss is the number worth computing, because it turns an argument into a threshold. Work it in money per unit, not in margin percentages. Take a 100 unit at a 40 percent contribution margin, so 40 of contribution. A 10 percent price rise adds 10 to the price and nothing to the cost, so contribution goes from 40 to 50. Profit holds as long as 50 times the surviving volume beats 40 times the old volume, and 40 divided by 50 is 80 percent. So: "we can afford to lose up to 20 percent of unit volume before this stops being worth it, and I would be surprised if a 10 percent increase cost us that much."

That single calculation, offered unprompted, does more for you than any amount of naming the three methods.

Where candidates lose these

Saying value-based and stopping. The word is not the analysis. If no number follows within a minute, it reads as a memorized answer.

Forgetting the floor. Even in a value-based case, know the unit cost. An interviewer who asks "what if the customer negotiates hard" is asking where your floor is.

Ignoring the installed base. A price change applies to existing customers too, and their reaction is usually a bigger number than the new-customer effect.

Missing the profit-pool shift. As in the dialogue above, a product that removes a consumable can raise the unit price and lower lifetime profit at the same time. Ask what else the customer stops buying, and ask it before you name a price rather than after.

No segmentation. One price for all buyers is rarely optimal and rarely necessary. If different customers get different value, saying so and proposing two tiers is a stronger answer than one perfectly optimized number.

A last word on the three lenses. They are a checklist for your own thinking, not a thing to recite. Announcing "I will apply cost-plus, competitor-based and value-based pricing" is the framework-naming move that costs you the room. Use them silently, then say the one that binds and why.

Drill this

Ten minutes, out loud, on any product in front of you.

  1. Minute 1: name which lens binds here and why, in one sentence about this product. Do not list all three out loud.
  2. Minutes 2 to 4: build the value number. What does the buyer pay today, what do they save or earn, what is the alternative. Land on an annual figure and a lifetime figure, stating each assumption as an assumption.
  3. Minute 5: before choosing a price, ask what the seller loses. Any service, consumable or upgrade revenue this product removes comes off the value before you take a share of it.
  4. Minutes 6 to 7: choose a capture share, say it out loud, and defend why not more.
  5. Minute 8: compute the break-even volume loss at that price.
  6. Minutes 9 to 10: name one more thing the price change breaks elsewhere in the business.

Step three is the one to force, and it is the step that changes the answer in the dialogue above. Most pricing answers stop at what the customer gains and never subtract what the seller gives up.

Frequently asked questions

Is value-based pricing always the right answer?

No. It works when the value is measurable, which tends to be easier in business-to-business than for undifferentiated consumer goods. Claiming it without a number is worse than a clean competitor-based answer with one.

How do I choose the capture share?

Say it explicitly and justify it rather than searching for a correct figure. A third is a common working default because it leaves the buyer a clear reason to switch, not because it is a law. Push higher when switching costs are high or the alternative is poor, lower when the buyer has real options or the benefit arrives slowly. And subtract any revenue you lose before applying the share at all.

Do I need to know elasticity formulas?

No. You need the break-even volume loss, which is arithmetic on margin and price change, and you need to reason about whether the real loss is likely to be above or below it. That is the same explain before you calculate habit applied to pricing.

What about cost-plus, is it ever the answer?

In commodities, regulated pricing and cost-plus contracts, it often is. Elsewhere treat it as the floor. Saying "cost gives us the floor" in one clause shows you know what it is for without spending the case there.

What if raising the price is right but the client cannot execute it?

Then the answer is a sequence rather than a number. Segment first and raise on the least price-sensitive group, or move the increase into the next product cycle where it reads as a new price rather than a rise. A recommendation that names the constraint and works around it beats one that ignores it.
