How to price a product when fees are a percentage of the price
Most pricing mistakes in online selling come from one assumption: that you can add the margin you want on top of your costs. It works in a shop where the only cost is the product. Online, marketplaces take a commission on the selling price, payment providers take a percentage of what the buyer pays, and advertising is usually measured as a share of revenue. Every one of those grows when you raise the price.
So the right question is not “cost plus how much?” but “at what price is my target margin left after everything?”. The calculator answers that directly. It separates the costs that stay the same whatever you charge (product, packaging, postage, fixed fees per order) from the charges that move with the price, and solves for the price that leaves your target.
Three prices every seller should know
- Break-even price: the floor. Below it each sale loses money.
- Minimum acceptable price: break-even plus the smallest margin you will accept. Useful for discounts, coupons and repricing rules.
- Target price: the price that leaves your target margin or your target profit per unit.
Already have a price? Type it in to see profit, margin and markup at that price, and how much of what the buyer pays goes to tax, fees and costs. Then enter competitor prices below the calculator, or use a marketplace-specific calculator with that platform's fee structure.
