How to pick the right calculator
Start with where the money comes from. If you sell on a marketplace, use that platform's calculator: the Etsy fee calculator, eBay fee calculator, or Amazon FBA calculator. If you get paid by card or invoice, use the PayPal, Stripe, or Square fee calculator.
Not sure where to sell? Marketplace Profit Compare ranks the same product across Etsy, eBay, Amazon, TikTok Shop, and Shopify. For pricing in general, the profit margin and markup calculators work for any business.
About these tools
Are Bussnizz calculators free?
Yes. Every calculator and browser-based PDF tool is free, with no account and no limit on how often you use it.
How accurate are the platform fee calculators?
They use each platform's published fee schedule, and every page shows the date the rates were last reviewed. Results are estimates: promotions, categories, taxes, and account terms can change your actual charges.
Can I change the fees a calculator uses?
Yes. Open Assumptions and rates on any seller calculator to edit percentages and fixed fees to match your own account.
Do the calculators work outside the US?
Yes. Choose your country in the top bar to switch currency. The Etsy calculator also has country presets for processing and regulatory fees.
