Price is the fastest lever a business has, and the one most companies handle worst. This deck starts with the simplest question, what a price has to sit between, and builds toward the tactics interviewers actually test: tiers, bundles, discounts, launch pricing, and price wars. You’ll do a little arithmetic along the way, because a pricing answer is only convincing when you can show what a few points of price do to profit. Nothing here assumes you’ve ever priced anything before. By the end you should be able to take a pricing case, find the real constraint, and defend a recommendation with a number behind it.

What is a price actually doing for a business, and what sets the floor and the ceiling it has to sit between?
Price sits between a cost floor and a customer-value ceiling, and it decides how the gap gets split.
Price is the mechanism that turns the value a company creates into money it actually keeps. Below your cost per unit you lose money on every sale, so cost is the floor. Above what the customer believes the product is worth to them, they simply walk away, so their perceived value is the ceiling. Everything in between is negotiable space, and where you land in it decides how much of the created value the company captures and how much the customer walks off with. Most pricing work is an argument about that split.

Two people buy the same $4 coffee at Kestrel Roasters. Your engagement manager says one of them would happily have paid $7. What is willingness to pay, and why does it vary so much between customers?
Willingness to pay is the most a customer would hand over before walking away, and it varies by person.
Willingness to pay is the highest price a particular customer would still say yes to. It differs from person to person because people differ in income, in how urgently they need the thing, in what alternatives they know about, and in how much they care about the brand or the convenience. A single posted price therefore leaves money on the table with the eager buyers and prices out the reluctant ones. Almost every advanced pricing tactic is an attempt to charge each customer closer to their own number.
Card 3 of 16
A client asks how you would even go about setting a price for a new product. What are the three classic approaches, and which one would you push them toward?
Cost-plus prices off your costs, competitor-based off rivals, value-based off what the buyer gains.
Cost-plus takes your cost per unit and adds a fixed markup, so the price is really a statement about your own factory. Competitor-based sets price relative to what rivals charge, which keeps you in the running but hands your pricing decision to someone else. Value-based starts from what the product is worth to the customer, measured against the next-best alternative they would otherwise buy. Value-based is the one to defend in an interview, because it is the only approach that looks at the person actually paying.
Card 4 of 16
Cost-plus pricing is the weakest of the three approaches, yet it is everywhere. Why do so many companies use it, and what goes wrong when demand softens?
Cost-plus is easy and defensible, but it ignores the customer and can spiral once volume drops.
Companies use it because the cost data already sits in their own systems, the markup is easy to justify to a board, and it feels fair. The trouble is that it ignores the customer entirely, so it underprices things people love and overprices things they don’t. It also feeds a spiral: when volume falls, fixed costs like rent and salaries spread over fewer units, the unit cost rises, the formula demands a higher price, and volume falls again. Interviewers like that failure mode because it tests whether you understand fixed costs.
Card 5 of 16
Your partner claims a 1% price increase beats a 1% volume increase. Ardleigh Cycles sells 100 units at $100, with $60 of variable cost a unit and $3,000 of fixed costs. Show her the math.
A point of price falls straight to profit, while a point of volume drags its variable cost along with it.
Start with the baseline: 100 units at $100 is $10,000 of revenue, less $6,000 of variable cost, the $60 a unit you only incur when you actually make one, and less $3,000 of fixed cost, leaving $1,000 of profit. Raise price 1% and the extra $100 lands entirely in profit, which becomes $1,100, a 10% gain. Sell 1% more units instead and you collect $100 more but spend $60 more, so profit is $1,040, only a 4% gain. Price is the sharpest lever a business has, which is why it draws so much consulting attention.
Card 6 of 16
What is price discrimination, and how does a company charge different customers different prices for essentially the same thing without causing an uproar?
Charge different buyers different prices by fencing them apart with something they cannot easily fake.
Price discrimination means selling the same or a nearly identical product at different prices to different buyers, so each one pays closer to their own willingness to pay. It only works if you can build a fence the customer can’t simply step over: a student or senior ID, a country, an advance-purchase deadline, a midweek rather than weekend booking. The fence has to line up with willingness to pay and be hard to fake, and it has to feel fair, which is why age and timing are tolerated while obvious personal targeting usually is not.
Card 7 of 16
Talbridge Software keeps arguing about which single price is right. Someone suggests offering three plans instead. What is versioning, and what makes a good-better-best ladder actually work?
Tiers let customers sort themselves by value, so each one pays closer to their own number.
Versioning means deliberately selling several versions of the same underlying product at different prices, so customers sort themselves instead of you guessing. It works when the differences between tiers track what different buyers genuinely value, things like seats, capacity, support speed, or warranty length. The top tier often earns its keep less by selling than by making the middle tier look reasonable, and the cheapest tier catches price-sensitive buyers who would otherwise buy nothing. Draw the lines wrong and everyone buys the cheapest plan.

Norwood Media sells a news subscription and a puzzle app separately. Some readers care about news, others about puzzles. Why might selling both together for one price make more money than selling them apart?
Bundling smooths out differing tastes, so one price can capture both customers instead of one each.
Suppose one reader would pay $8 for news and $2 for puzzles, while another would pay $3 for news and $7 for puzzles. Priced separately, news at $8 and puzzles at $7 each sell to only one reader, for $15 in total. Bundle the two at $10 and both readers buy, for $20, because their combined willingness to pay is similar even though their tastes point in opposite directions. Bundling wins when tastes vary that way and the extra component costs almost nothing to deliver. Unbundle when one piece is strong enough to sell alone.

Ashcombe Devices is launching something nobody else sells yet. Should it come in low to grab the market, or start high and walk the price down? Make the case for each.
Skim high when early buyers will pay a premium, penetrate low when scale and lock-in decide the winner.
Price skimming starts high to harvest the buyers who want the product most, then steps down over time to reach each next layer of demand. Penetration pricing starts low to win share fast, betting that volume brings lower unit costs, habit, or network effects that make the position hard to attack later. Skimming suits real differentiation, patent protection, and slow-moving rivals. Penetration suits markets where scale drives cost down or customers rarely switch once signed up. Skimming invites entrants, and penetration can leave you unable to raise price later.
Card 10 of 16
A client’s head of retail insists on ending every price in .99 and printing a crossed-out “was” price on the shelf tag. How much of that is real, and how much is folklore?
Buyers judge a price against a reference point, so framing matters, but it can’t rescue a weak offer.
People rarely judge a price on its own. They compare it against a reference point, whatever they last paid, what sits beside it on the shelf, or the crossed-out figure on the tag, and that comparison drives whether the price feels fair. Charm pricing, the .99 ending, does show measurable effects in some categories, but the size varies a lot across products and studies, and it can cheapen a premium brand. Treat framing as a small, testable adjustment on top of a price set from customer value, not a substitute for it.
Card 11 of 16
Sales at Pallant Paper wants a 10% discount to hit the quarter-end target. Gross margin is 40%. How much extra volume does that discount have to generate just to break even on profit?
A 10% discount on a 40% margin needs 33% more volume just to stand still.
Take a $100 sale carrying $60 of variable cost, so $40 of contribution, the money left after the costs that move with each unit. Discount 10% and you collect $90 while the cost stays $60, so contribution drops to $30, a quarter of it gone. To earn the same total contribution you now need $40 divided by $30 of volume, which is 33% more units. The thinner the margin the worse this gets, which is why pricing teams fence discounts to buyers who genuinely wouldn’t have bought otherwise.
Card 12 of 16
What’s the difference between subscription and usage-based pricing, and what does each one do to the customer’s decision and the seller's revenue?
Subscriptions buy predictability, usage pricing ties what a customer pays to what they actually consume.
A subscription charges a recurring fee for access, so the customer pays the same whether they use the product once a month or constantly, and the seller gets revenue that is easy to forecast as long as churn stays low. Usage-based pricing charges per unit consumed, per gigabyte, per call, per hour, so the bill tracks the value the customer draws. Usage pricing lowers the barrier to starting and grows with a successful account, but it makes forecasting harder. Many companies now blend the two, a platform fee plus metered usage on top.

Two hardware chains on the same highway keep undercutting each other until neither one makes money. Why do price wars start so easily, and why is winning one so hard?
Cutting looks smart for each rival on its own, and everyone ends up poorer with the same market shares.
With few players and similar products, cutting price looks like the better move whichever way your rival goes: if they hold, you take volume, and if they cut, you cannot afford to be the expensive one. So both cut, both keep roughly the share they started with, and both earn less, which is the classic prisoner’s dilemma shape. Price is also the easiest move for a rival to see and copy within days, unlike a product improvement. Winning takes a durable cost advantage the other side simply can’t match.

Riversedge Tools hasn’t raised prices in six years and its input costs are up 20%. The CEO is terrified of losing customers. How would you get an increase through, and how would you test it first?
Raise price narrowly first, give customers a reason and a cheaper option, then measure what you lose.
Start where you have the most room: products with few substitutes, customers who buy on service rather than price, and segments where your price has drifted furthest below what the product is worth. Test rather than announce, by raising price in a few regions or accounts and watching volume against comparable ones you left alone. Give customers a reason they can repeat, a real input cost or a genuine improvement, and a cheaper stripped-down option so leaving is not the only response. Then check whether the volume lost was worth less than the margin gained.

Your team pulls Holloway Ceramics’ invoices and finds the average customer pays 22% below list. The VP calls it a pricing leak. What is a pocket price waterfall, and what would you look for in it?
Pocket price is what’s left after every discount and term, and it is rarely close to list price.
List price is the number on the price sheet. Subtract the negotiated discount and you get invoice price, then subtract everything that comes off after the invoice, volume rebates, early-payment terms, freight, co-op marketing allowances, returns, and what’s left is the pocket price, the cash the company genuinely keeps. The waterfall lays those steps out one at a time so you can see where the money went. Nearly every waterfall shows similar customers paying wildly different pocket prices for no defensible reason, and closing that spread is often the fastest margin win available.

Brackwell Instruments can cut price 15% to win a distributor that would add 40% to volume, or hold price and stay a premium niche brand. Gross margin is 45%. How do you advise them?
Test whether the volume clears the margin hurdle, then ask what the low price does to everything else.
Run the arithmetic first. On $100 with $55 of variable cost, contribution is $45, and a 15% cut leaves $85 against the same $55, or $30, so you’d need 50% more volume to break even against the 40% on offer. That alone says no, and the strategic case is worse: a price that low leaks to existing customers and resets what the market thinks the product is worth. I’d counter with a fenced offer, a stripped-down model or a volume rebate, that gives the distributor a lower price without repricing the flagship.
