Marketplace Fee & Profit Calculator
Model your own percentage and fixed marketplace fees to estimate per-sale costs and profit, find a target selling price, or compare two fee structures.
Use this calculator to estimate marketplace selling costs and profit using the fees that apply to your own platform, category and account.
Marketplace fees vary by platform, region, category and service level. Enter the fee percentages and fixed charges you want to model rather than relying on preset fee schedules.
The starting numbers are illustrative assumptions, not a platform fee schedule. Use the same currency for every amount; the dollar sign is generic and no currency conversion is performed. Blank optional costs and fees are treated as zero.
Calculations run locally in your browser. Your financial inputs are not saved.

About this calculator
How marketplace fees affect profit
Marketplace profitability depends on both percentage-based fees and fixed costs. Lower-priced products can be especially affected by fixed per-sale charges.
- This calculator estimates contribution profit per sale. It does not include income tax, overhead or other business-wide costs unless you enter them.
- Marketplace fee structures change frequently. Verify the fees that apply to your platform and category.
Taxes and marketplace remittance
Sales taxes collected from buyers and marketplace tax-remittance rules vary by jurisdiction and platform and are not included unless you enter them as a cost elsewhere.
Manual planning estimates, not accounting or tax advice. The dollar sign is generic; use one currency throughout. No marketplace connections, transaction imports or saved financial data are used.
