What's in the file
- Know where an item nets the most before you list it
- Fees, payout, profit, margin and breakeven for five marketplaces from one set of inputs (Profit Calculator)
- Every fee dated, with its official source (Platform Fee Settings)
- Start Here, Setup and Help tabs
A formula-only Google Sheet with no scripts or add-ons, and no connection to your marketplace accounts. You type one item's numbers, and the fees, profit and breakeven price fill in for all five marketplaces side by side. Fees verified as of October 31, 2026.
Who it's for
- You sell on more than one marketplace and want to know where an item nets the most
- You want the fee math done without building the spreadsheet yourself
- You are not ready to track inventory and sales yet (the Tracker does that)
