All Platform Fee Calculators
10 free calculators to compare seller fees across marketplaces and payment processors. Know exactly what you'll earn before you sell.
Why platform fees matter
Marketplace fees can turn a profitable sale into a break-even order if you only look at the customer price. These calculators estimate the money left after common platform, payment processing, and selling fees so you can set prices, compare channels, or decide whether a discount still leaves enough margin.
How to use the results
Start with the sale amount, then compare the net earnings across the platform you actually use. Treat the result as an estimate, because platforms can change rates, promotions, seller tiers, and payment rules. For business planning, add shipping, refunds, ad spend, packaging, and taxes separately before deciding your final price.

A platform fee calculator focuses on the charges that are predictable from the sale amount: commission percentages, payment processing percentages, flat transaction fees, and common platform fees. It does not replace bookkeeping software or tax advice, but it does give sellers a quick way to check whether a listing price, freelance quote, or marketplace order still makes sense after the platform takes its share.
Before using a result for pricing, compare it with your own seller dashboard and include the costs the platform cannot know: shipping labels, packaging, returns, ads, discounts, taxes, and currency conversion. Those extra costs often decide whether the sale is actually profitable.
