01What a pricing case is really asking
Pricing cases come in four shapes. Spot which one you have in the first minute, because each starts in a different place.
In every shape, price is a lever on profit, not the goal. A price that maximises revenue or market share can still lose money, so every pricing answer should end on profit.
02The three anchors: floor, reference, ceiling
Price sits in a range. Three anchors define it, and naming all three is what separates a structured answer from a guess.
- Cost floor. Variable cost per unit is the hard floor in the short run: below it, every sale loses money. Over time, price must also cover fixed costs.
- Competitor reference. What the customer would pay for the next best alternative, adjusted for how much better or worse you are.
- Customer value ceiling. The most a customer would rationally pay: the value your product creates for them. Above it, nobody buys.
Cost tells you whether a price is viable. Customer value tells you what's possible. Competitors tell you where in that range customers will compare you. Cost should never set the price on its own: cost-plus pricing ignores what customers would happily pay.
Weak
I'd look at our costs, add a healthy margin of about 30%, and check that the result is in line with competitors.
Strong
I'd treat price as a range. Our variable cost sets the floor. The value the product creates for the customer sets the ceiling: what they save or gain compared with their next best option. Competitors' prices show where customers will compare us. Then I'd test a few prices inside that range on volume and profit. I'd start with customer value, because for a new product that's where the upside is.
Why: Cost-plus leaves money on the table when a product is worth far more than it costs, and prices you out when it's worth less. The strong answer uses all three anchors, ends on profit rather than price, and says where to start and why.
03Value-based pricing and willingness to pay
The ceiling comes from economic value to the customer: what they pay today for their next best option, plus the value of everything you do better, minus anything you do worse.
Differences can be negative: a missing feature or a switching cost lowers the ceiling.
In B2B you can usually put a number on the difference: hours saved, failures avoided, energy cut. In B2C, value is partly emotional, so you lean more on what customers say and do.
Don't price at the ceiling. Leave the customer a reason to switch: if you take all the value, they're indifferent, and switching costs effort and carries risk. Splitting the value of your advantage with the customer is a sensible starting point, then adjust for how proven and visible that advantage is.
Segment as you go. Different customers get different value, so a single price leaves money on the table with some and loses others. That's the case for tiers, versions and volume discounts.
04Elasticity and the volume a price change needs
Price elasticity is the percentage change in volume for a 1% change in price. At -2, a 10% price cut lifts volume by about 20%. Demand is more elastic when there are close substitutes, when the product is a big share of the customer's spend and when switching is easy.
Elasticity alone won't tell you whether a price change pays. Margin decides. Ask: how much must volume rise to make up for the margin we give away on every unit we already sell?
New unit margin = old margin minus the cut. Use $ per unit or % of price, not a mix.
A product sells at $100 with a $60 variable cost, so its unit margin is $40. Cut the price 10% to $90 and the margin falls to $30. Volume must rise by $10 ÷ $30 = 33% just to keep contribution flat.
Price rises work the same way in reverse: volume can fall by rise ÷ (old margin + rise) before profit drops. At a 20% margin, a 10% rise survives losing a third of the volume, while a 10% cut needs volume to double. At low margins, cuts are expensive and rises are surprisingly safe.
Check yourself
A product sells for $80 and costs $60 a unit to make. The client wants to cut the price by 10%. Roughly how much must volume rise to keep contribution flat?
05Launch pricing: skimming or penetration
For a new product the question is often the path as well as the price. Skimming launches high and comes down over time. Penetration launches low to win share fast.

The anchors are the same. What changes is who decides, how value is shown and how the price is actually paid.
07Worked example: pricing a new sensor
Worked example
A failure-prediction sensor for factory pumps
The prompt. Our client makes industrial pumps and is launching a sensor that predicts pump failures. What should it charge, and should it accept the sales team's push to launch at $1,000?
1. Cost floor
Each sensor costs $400 to make and install. Launch fixed costs, mainly sales and support staff, are $5m a year. So $400 is the floor, and we need enough volume above it to cover the $5m.
2. Competitor reference
Factories today fit a basic vibration monitor at $500 a pump. That's the next best alternative, so customers will compare us with $500.
3. Customer value ceiling
Our sensor catches failures the basic monitor misses. Over its life it prevents one extra failure per pump on average, and a failure costs the factory $1,500 in repairs and lost output. Value to the customer = $500 + $1,500 = $2,000: the ceiling.
4. Pick a price
The range is $400 to $2,000. We split the $1,500 of extra value with the customer: $500 + $750 = $1,250. The customer is still $750 better off than with the basic monitor, and our unit margin is $1,250 - $400 = $850, or 68%.
At $1,250 we break even at $5m ÷ $850 ≈ 5,900 sensors a year. The plan is 10,000, which gives $8.5m of contribution and $3.5m of profit.
5. Test the price cut
Sales wants $1,000, a 20% cut. The unit margin falls from $850 to $600, so volume must rise by $250 ÷ $600 ≈ 42%, to about 14,200 sensors, just to match today's profit.
Sales expects 12,000 sensors: 20% more volume for a 20% cut. Even if that's right, profit falls by $1.3m. Recommend $1,250, with volume discounts for large fleets rather than a lower list price.
Cheat sheet
The lines worth rereading the night before.
- 1Price is a range: variable cost is the floor, customer value is the ceiling, competitors place you inside it.
- 2Customer value = next best alternative's price + the value of your differences. Price below it so customers gain from switching.
- 3Never price on cost alone. Cost tells you whether a price is viable, not what it should be.
- 4Volume needed for a price cut = cut ÷ new unit margin. At a 40% margin, a 10% cut needs 33% more volume.
- 5Low margins make cuts expensive and rises safe. Do the maths before saying 'volume will go up'.
- 6Ask whether competitors will match. A matched cut gives you the lower margin without the volume.
- 7Skim when you're differentiated and protected; go for penetration when share, scale or network effects pay.
- 8In B2B, check the gap between list price and pocket price before touching the list price.

Questions candidates ask
What is the pricing framework for case interviews?
Set price as a range with three anchors: your variable cost is the floor, the value to the customer is the ceiling, and competitors' prices show where customers will compare you. Then test candidate prices on volume and profit, not revenue.
How do you work out the volume needed to justify a price cut?
Divide the price cut by the new unit margin. A product at $100 with a $60 variable cost has a $40 margin; a $10 cut leaves $30, so volume must rise by $10 ÷ $30 = 33% to keep contribution flat.
What is value-based pricing?
Pricing from what a product is worth to the customer rather than what it costs you. Start from the price of the customer's next best alternative, add the value of your advantages, subtract your disadvantages, and price below that ceiling so the customer gains from switching.
When should a company use penetration pricing instead of skimming?
When winning share early pays off later: price-sensitive buyers, strong scale economies, network effects, or a race to lock in customers before rivals arrive. Skimming suits a differentiated, protected product with buyers keen to pay more early.
