Marketplace Pricing Calculator

By the CalcMundi team · Updated October 22, 2026 · Formulas checked against standard financial math

Enter your cost, shipping and the marketplace fees to find the price that gives you the margin you want.

How it is calculated

Price = (cost + shipping + fixed fee) ÷ (1 − referral fee − taxes − ads − margin). That way, your margin is on the selling price after every fee.

Fees change by platform, category and plan. Check the current numbers in your seller account.

Example

A product that costs $12, with $5 of shipping, a 15% fee and a $0.30 fixed fee: to keep a 20% margin, sell it for $26.62, for a profit of about $5.32 per sale.

Frequently asked questions

Should I include returns?

Yes, if you have them. Add the average cost of returns per sale to the shipping field.
