Charging What It Costs You Is the Least Sensible Way to Set a Price
Cost plus pricing is simple, defensible and widely used. It also anchors the price to a number the customer does not care about, which usually leaves money uncollected.
The Two Approaches
Cost plus pricing starts with what the product costs to produce and adds a target margin. A component costing 60 dollars with a 40 percent markup is priced at 84. Value based pricing starts from what the product is worth to the buyer and prices as a share of that value, with cost serving only as a floor below which the sale is not worth making.
Cost plus is far more common, and the reasons are practical rather than analytical. Cost is a number the company already has. Value to a customer is a number it has to go and estimate.
Cost tells you the lowest price you can accept. It tells you nothing at all about the highest price you could get.
Why Cost Plus Persists
It is easy to compute, it is easy to defend in a negotiation, it guarantees a margin on every sale if the cost figure is right, and it feels fair to both sides. In genuinely commoditised markets, where the product is interchangeable and the customer can compare identical offerings, it also gets close to the right answer, because competition has already pushed price toward cost.
Those conditions are narrower than the method usage suggests.
The Two Failures
Cost plus fails in both directions, and both failures are invisible from inside the company.
Underpricing valuable products. A cheap to produce component that saves a customer 50,000 dollars a year in downtime is priced at 84 dollars because it cost 60 to make. The customer accepts instantly, every time, and the sales team reports strong performance. Nothing in the internal reporting reveals that the product could have been priced at several times the level.
Overpricing expensive ones. A product that was costly to develop gets a price that reflects that spending. The customer does not care what it cost to develop. If the value delivered is below the price, it does not sell, and the company concludes the market is difficult rather than that the price was anchored to a sunk cost.
| Situation | Cost plus result | What is missed |
|---|---|---|
| Low cost, high value | Priced too low | Margin left on the table |
| High cost, low value | Priced too high | Product does not sell |
| True commodity | Roughly correct | Little, competition sets it |
The Circularity Problem
There is a structural flaw in cost plus that gets little attention. Unit cost depends on volume, because fixed costs spread across units. Volume depends on price. Price, under cost plus, depends on unit cost.
The loop runs the wrong way. If volume falls, unit cost rises, so the formula raises price, which reduces volume further. This is a documented failure pattern in businesses with high fixed costs, and it accelerates decline exactly when the correct response would have been to hold or cut price to defend volume.
Estimating Value Without Guessing
The objection to value based pricing is that customer value is unknowable. It is harder to measure than cost, but it is not unknowable, and industrial pricing teams estimate it routinely.
The usual anchor is the next best alternative. If a customer solves the problem today with a competing product at 200 dollars, and the new product saves an additional 300 dollars in labour, the economic value is 500. The price sits between the alternative and the total value, with the split determined by competitive pressure and negotiating position.
This requires talking to customers about their economics rather than only about features, which is a sales capability many organisations do not have.
Where Cost Still Belongs
None of this makes cost irrelevant. Cost defines the walk away point. A price below avoidable cost loses money on every unit and cannot be fixed by volume. Cost is also what determines whether a value based price is worth pursuing at all.
The distinction is that cost sets the floor and value sets the ceiling. Cost plus collapses the two into one number and then treats the floor as though it were the answer.
The Bottom Line
Cost plus pricing survives because it is administratively convenient, not because it produces good prices. It systematically underprices products that deliver disproportionate value, overprices those that do not, and contains a circularity that raises prices into falling demand. Cost belongs in a pricing decision as a floor. What the customer would otherwise have paid to solve the problem belongs there as the ceiling, and the difference between those two numbers is where the actual pricing decision lives.
