Fee Calculators
Every marketplace and payment processor takes a cut before a sale reaches your bank account — a referral fee, a fulfillment fee, a processing fee, sometimes all three stacked on one order. These calculators break each fee out by line item, cite the platform's own published rate, and show the number that's actually yours.
Informational only, not professional advice. Every calculator states its scope and sources — check the methodology section on each tool page.
