Selling Price Calculator
Enter your cost and target, get the price: solve for gross margin, for contribution margin after real fees, or for a profit amount per order, with the formula and its numbers shown.

Decision numbers
"Contribution profit" here means revenue minus product cost minus the costs you entered above, and nothing else. It is not net profit: returns, packaging, tax, wages, rent and overhead are not included unless you typed them in.

Internal math keeps full precision; only displayed amounts are rounded, half-up, at the currency's decimal places.
The price that survives its own fees
The classic mistake in pricing for marketplaces: solve the price for a 30% margin, then watch the platform take 15% of that bigger price and land you at 19%. Percentage fees are self-referential, so the correct price comes from algebra, not addition. Pick the contribution basis above, enter your fee rate and per-order costs, and the solver returns the price whose after-fee margin is actually the number you asked for, then proves it in the results below. The "Show the math" panel displays the formula with your values substituted, so you can put it in a spreadsheet and get the same answer.
Selling price FAQ
How do I calculate a selling price from a target margin?
For gross margin: price = cost / (1 - margin). A $60 product priced for a 40% margin sells at $100. This is the formula most calculators stop at, and it silently ignores every fee you pay. This calculator makes that explicit: the gross basis is labeled "ignores fees by definition", and a second basis solves the price that hits your margin AFTER percentage and fixed selling costs.
How does pricing after fees actually work?
Percentage fees scale with the price you are solving for, which is why you cannot just add them afterward. The solver uses P = (C + F) / (1 - r - m): C is product cost per order, F your fixed per-order costs, r the percentage fee rate, m the target contribution margin. Raising the price to cover a percentage fee raises the fee too, and this formula accounts for that feedback exactly. The solved price is verified against the same engine that displays your results.
Why does the calculator reject my target sometimes?
Because some targets are mathematically impossible. If your percentage fees are 15% and you ask for a 90% contribution margin, fees plus target claim 105% of every unit of revenue, leaving less than nothing for the product. The calculator rejects r + m of 100% or more with an explanation instead of returning a negative price or a silently wrong one.
Should I price from cost or from the market?
Both, in that order. Cost-plus pricing, which this tool automates, sets your floor: below it you lose money on every sale, and the break-even output makes that floor explicit. The market sets your ceiling: what customers compare you against. Price between the two based on positioning. A calculator can only give you the floor with certainty, and pretending otherwise would be marketing, not math.
