How the math works
Price = cost ÷ (1 minus fee% minus target margin%). It is the price at which, after the platform fee, your net margin equals your goal.
Profit = price minus fee minus cost. Markup = profit ÷ cost.
How to price for a target margin
Most sellers price by adding a markup to cost, then discover the platform fee quietly ate their margin. Pricing the other way, from the margin you want, avoids that. You decide the net margin to keep, account for the fee, and solve for the price.
Because the platform fee is charged on the selling price (not the cost), you can't just add the fee to a cost-plus price; the math has to solve for price so margin holds after the fee. This calculator does that.
If the fee percentage plus your target margin reaches 100%, there is no price that works. Lower the target first.
Frequently asked questions
How is the recommended price calculated?
Price = cost ÷ (1 minus fee% minus target margin%). This guarantees that after the platform fee, your net margin equals the target you entered.
Why can't I just add my margin to the cost?
Because the platform fee is taken from the selling price, not the cost. Adding margin to cost ignores the fee and leaves you short of your goal.
What margin should I target?
Many ecommerce sellers target 30 to 45% net so there is room for ads, discounts and returns. Thinner categories run lower.
