About Us

NetFeeCalc helps online sellers and independent workers understand the gap between gross revenue and the money they keep. We publish calculators and worked examples for marketplace fees, payment processing, and profit margins.

Start with an order you know

Use the Seller Fee Calculator to estimate proceeds using your own fee rate and costs. For Etsy orders, use our standard fee calculator and compare attributed advertising charges with the Offsite Ads calculator.

How to read our estimates

Our guides identify the inputs, explain the fee basis, and link to official platform policies where applicable. Example inputs are illustrative. Match the country, currency, and account terms to your situation before comparing your estimate with a payout statement.

Sources and corrections

Platform rules can change. If a source or result appears out of date, send the page address and the relevant official policy through our contact page. See how we disclose commercial relationships in our Terms of Service & Disclosure.
