Your price is a brand decision wearing a finance costume.

Most brands set price by opening a spreadsheet. Take the unit cost, add a margin someone found in a sector report, round it to something that looks confident, and check it against the nearest competitor's website. The process feels rigorous. It produces a number that is defensible in a meeting and indefensible anywhere else.

The problem is not the arithmetic. It is the order of operations. Price is the last thing the customer meets, and it undoes everything the other decisions worked to build.

Price is the loudest thing you say

Positioning is subtle. A customer can read a manifesto, disagree with it, and buy anyway. Price is not subtle. It is a sentence, in a currency, that anyone can understand without knowing anything about the brand.

And it is permanent in a way that copy is not. A line of advertising can be changed on Tuesday. A price, once customers have seen it, is a reference point that every future price is measured against — including the ones you would rather charge.

A discount does not teach a customer the product was worth more. It teaches them it was not.

This is why price is a positioning decision that happens to be expressed in money. Set it before the positioning and you will find yourself adjusting one to fit the other, which is how brands end up expensive for reasons they cannot articulate.

Why cost-plus fails in a specific way

The spreadsheet is not stupid. It does one thing well: it guarantees you do not lose money on the unit. The failure is what it cannot see.

It cannot see the second purchase. A customer who tried you at a discount, waited for the discount to come back, and bought at full price is worth considerably more than the margin you gave away, and the spreadsheet will never show you that trade, because it happens a year later and in a different report.

It also cannot see the substitution. Raise the price to a competitor's level and you have not become that competitor. You have simply joined the set of things your customer chose between, and price is the only thing they will compare.

What actually helps

Three things, in this order, and the order is the point.

• Name the alternative you are competing with. Not the obvious rival — the thing the customer would otherwise spend the money on. Often a different category entirely. Price is read against whatever it is placed beside.
• Decide what you are refusing to be. A cheaper version of you is not a neutral option, it is a position, and it is the one most brands cannot afford.
• Set the price once the positioning is arguable. If two people in the room would describe the brand differently, the price will be a compromise between two different products. Fix the description first.

Then build the model underneath it — unit economics, channel margin, the volume the price requires to clear the fixed costs. That work still matters. It is just not a decision about what the brand is.

When to break the rules

Under-costing is legitimate in three situations, and they have something in common: they are buying a position, not a margin.

Entering a market where you need to establish a reference point. Launching a format you have to explain. A range that deliberately ladders from one entry point. In each case the discount is doing a job that advertising would otherwise do more expensively.

What is not legitimate is a permanent low price justified as a marketing budget. That is a margin decision wearing a strategy costume, and it is the mirror image of the mistake this started with.
