Payments & Fees Calculators for Freelancers and Businesses

Payment processors and tax authorities each take a slice of every transaction, and the percentages add up faster than most invoices reveal. A 2.9% Stripe fee here, a 30¢ fixed charge there, a 20% VAT on top, and suddenly the headline rate you quoted is not the cash that lands in your account. These calculators surface those costs in plain numbers — before you send the invoice, not after.

Whether you're a freelancer setting an hourly rate that survives processor cuts and self-employment tax, or a SaaS founder deciding which payment provider to default to at checkout, this category has the fee-by-fee math. Everything runs locally in your browser, with the formulas shown beside each result so you can verify the logic against the provider's own pricing page.
