Main tools
What can you calculate?
Global Seller Fees helps online sellers estimate payment processing fees, marketplace charges, tax-rate scenarios, reverse fees, and net profit. Calculators are browser-based and show the assumptions used for each estimate.
Choose the right calculator
- PayPal
Use when pricing invoices, checkout payments, or reverse-calculating a target received amount after PayPal-style fees.

Use when estimating online card processing under the shown US limited assumption or your own custom Stripe rate.
- Etsy
Use when product cost, shipping cost, listing fees, payment processing, and transaction fees affect margin.

- VAT/GST/Sales Tax
Use only to separate tax-exclusive and tax-inclusive amounts from a rate you already checked.
- Platform comparison
Use for side-by-side estimates under the same sale assumptions, not as a platform recommendation.

Why inputs stay private
Calculator inputs run in the browser. No login is required, and you do not need to enter names, email addresses, tax IDs, bank details, order IDs, or customer information. The inputs are browser-only calculation state and are not intentionally sent to a server, analytics event, URL, cookie, localStorage, or sessionStorage.
