Two companies sell a nearly identical component. The first prices it the way it prices everything: cost plus 40%. Its cost is $60, so the price is $84. The second charges $130 for the same function and outsells the first. The sales team is convinced the market is irrational. It is not. The first company let its cost accountant set its pricing strategy, and its cost is the single input its customer cares least about.
The core insight
The price a customer will pay has almost nothing to do with what the product cost you to make. It has to do with what the product is worth to them, and what their alternatives cost.
Cost-plus pricing ignores both. It takes your internal cost, a number that reflects your efficiency, your scale and your supplier relationships, and marks it up by a habitual percentage. The customer sees none of that and values none of it. They compare your price to the value they get and the next best option they have. Your cost is invisible to them and irrelevant to their decision.
This creates two failures that run in opposite directions. When your cost is low, cost-plus leaves money on the table: you price at $84 into a market that would have paid $130, and hand the difference away on every unit. When your cost is high, usually because you are less efficient than a competitor, cost-plus prices you out: you mark up an inflated cost, land above what the market will bear, and then blame the market. In both cases the problem is the same. You anchored the price to the wrong number.
"Your cost tells you the lowest price you can afford to accept. It tells you nothing about the highest price you can command."
The framework: the three price anchors
Every price sits between three reference points, and a good price is set by considering all three. Cost-plus uses only the first.
-
1The floor is your cost.
The lowest price you can accept without losing money on the unit. It sets a boundary, nothing more. It tells you what you cannot go below. It says nothing about what you can charge.
-
2The ceiling is the value to the customer.
What the product is worth to the buyer: what it earns them, saves them, or what their next best alternative costs. It sets the highest price the market will bear. This is the number cost-plus never asks about, and it is the one that actually determines the price.
-
3The position is where you sit between floor and ceiling.
Set by your differentiation and the competition. A genuinely better or better-positioned product sits near the ceiling. A commodity in a crowded market sits near the floor.
The component run through all three
| Anchor | Value | What it tells you |
|---|---|---|
| Floor, your cost | $60 | Do not price below this |
| Ceiling, customer value | $150 | The most the market will bear |
| Competitor position | $130 | Where a strong rival sits |
| Cost-plus price | $84 | Anchored to the wrong number |
Cost-plus produced $84 by looking only at the floor. The competitor, pricing off the ceiling and their position, charges $130 and captures $70 of margin per unit against your $24. They are not overcharging. You are undercharging, by refusing to look above the floor. The $46 gap between your price and theirs is not the market being irrational. It is the price of anchoring to your cost.
Why experienced managers get this wrong
-
1They treat cost as information about value.
It is not. Cost tells you about your operation. Value tells you about the customer. Cost-plus quietly assumes the two are related, and they usually are not. A cheap-to-make product can be enormously valuable, and an expensive one can be worth little.
-
2They apply a uniform markup across different products.
The same 40% goes on everything, regardless of how differentiated or valuable each product is. The undifferentiated commodities end up overpriced and the genuinely valuable products end up underpriced, which is exactly backwards.
-
3They mistake cost-plus for fairness.
Cost-plus feels defensible: it is transparent, it is even-handed, nobody can accuse you of gouging. That comfort is why it survives. But fairness to your own cost structure is not the same as a price that reflects value, and the market does not reward the gesture.
-
4They blame the market when high cost prices them out.
When an inefficient cost base pushes the cost-plus price above the ceiling, the instinct is to conclude the market is too cheap. The real message is that the cost is too high. Cost-plus hides your inefficiency inside your price and calls it a pricing problem.
Putting it to work tomorrow
- Estimate the ceiling before you set the price. For each significant product, ask what it is actually worth to the customer: the economic value it delivers, or the cost of their next best alternative. This is harder than reading your cost sheet, which is precisely why most companies skip it and precisely why doing it is an advantage.
- Use cost as the floor, not the anchor. Keep your cost. You need it to know where you cannot go. Then set the price by working down from the ceiling and your position, not up from the floor.
- Reprice your most differentiated products first. The products where your value most exceeds your cost are where cost-plus is leaving the most money on the table. That is where a value-based reprice pays off fastest. The value-based price calculator sizes that gap for one product in a few seconds.
Cost-plus is genuinely appropriate in a few settings: true commodities with no differentiation and transparent markets, where price is set externally and value equals the going rate, and cost-plus contracts where the pricing method is the agreement itself. And value-based pricing is not a licence to charge anything: the ceiling is real and customers walk when you exceed it. Estimating value is also imperfect and requires judgment. The point is not that cost is useless. It is that cost is the floor, and a price set only from the floor is a price that never asked the real question.
The principle worth keeping
Cost-plus pricing is the confession that you only ever asked the first question.
"The margin you are missing lives entirely in the second."
