Stop guessing what you keep on a sale.

This spreadsheet shows a seller what they actually take home on Amazon FBA, Etsy, Shopify and TikTok Shop - and what they must charge to hit the profit they want.

WHAT IT GIVES YOU

• Every fee on its own line, never one vague “fees” total
• Effective fee rate: all fees as a share of what the buyer paid. Almost always higher than the headline percentage
• Break-even price: below it, you lose money on every order
• The price you must charge for your target margin, or for a flat target profit per order
• The most you can spend on ads per order and still hold that margin, plus your break-even ROAS
• Three worked examples, so you see it working before you type in your own numbers

BUILT TO BE TRUSTED

• Every rate comes from the platform’s own official fee page, with the URL and date read, on the FEES tab
• No rate is buried inside a formula: when fees change you edit one cell
• One-page START HERE guide in plain English
• Works in Excel and Google Sheets. No macros, no add-ons, no “update links” prompts
• Returns handled the cautious way, and the sheet says so

WHO IT IS FOR
US, UK and EU sellers on Amazon FBA, Etsy, Shopify and TikTok Shop.

One honest note: Amazon’s FBA fulfilment fee depends on size, weight, price band and season, so the sheet asks for your own per-unit figure instead of guessing. Everything else is pre-filled.
