Online Shop Fee and Profit Calculator (Multi-Platform)

For makers, small brands and resellers who sell on more than one channel and want to know which one actually pays.

Fee Settings holds editable presets for 7 platforms: Etsy, Shopify Basic, Amazon Professional and Individual, eBay, TikTok Shop and your own website with Stripe. Each row lists the marketplace or referral %, minimum fee, processing % and fixed fee, per-order and small-order fees, per-item fees, ads or affiliate fees and the monthly plan, with its source and the date it was checked (2026-11-09). Fees change and differ by category and country, so every value is an input you can update, and the workbook says so: verify current fees before you rely on them.

On Compare, enter one product's price, the shipping you charge and your costs: every platform's fees, payout, profit per order, margin, break-even price and the price for your target margin appear side by side, ranked. Price Finder shows the price you need on each platform for 0% to 40% margins. List up to 300 SKUs on Products, each on its platform, and the Dashboard totals monthly revenue, fees, fees % and profit by platform, flags loss-making SKUs and shows your top sellers by profit.

Included: worked-example and blank workbooks (6 sheets, 4,040 formulas) and a 5-page quick-start guide (US Letter and A4) with the fee presets and sources, a worked example, how every fee is calculated and pricing tips.

Fee figures are estimates, not guarantees. General information, not financial or tax advice.
