Flip-Profit Calculator for Resellers
A flip-profit calculator nets a single resale flip honestly — after the platform's fee, shipping, and the cost of goods. Because the sale price isn't the profit: the thrift-store price plus supplies plus a share of your sourcing miles is the real cost, and a flip that looked great can be thin. Enter what it cost, what it sold for, the fee, and the shipping, and this reseller profit calculator returns your true net profit, ROI, and margin. Use it right here in your browser, or download the spreadsheet to keep.
Flip-Profit Calculator
Example flip shown — edit any fieldThis is one flip on one platform — no inventory list, no per-platform comparison, no cost-of-goods rollup, and nothing saved (the full workbook does all of that). Pre-filled with an illustrative example; replace every figure with your own, and use each platform's current fee. A budgeting aid, not tax, accounting, or legal advice.

What it does
- Builds the true cost of goods on one item — what you paid, plus supplies, plus a fair share of your sourcing mileage.
- Applies the platform's fee (percentage plus any flat per-order fee) to the item and the shipping you charge.
- Returns the net profit, the ROI on the money you tied up, and the margin — for one flip on one platform.
- Runs entirely in your browser — nothing is sent anywhere, and nothing is saved.
Own it, don't rent it
Want every flip, not just one?
This free tool nets one flip on one platform. The full workbook runs the whole operation — an inventory & profit log that tracks every item from buy to sale, per-platform fee profiles, a sourcing-trip mileage log, a performance view of which platforms and categories pay, and a dashboard with a 1099-K reconciliation, in one connected spreadsheet (Excel, Google Sheets, or LibreOffice) plus four guides.
A one-time purchase you keep and reuse on every flip — the structured workbook between a blank spreadsheet and a rented monthly reseller app.
A business and record-keeping aid, not tax, accounting, or legal advice. Every figure is illustrative — platform fees change and tax rules differ by place and year, so enter your own current numbers. Not affiliated with or endorsed by any marketplace. Free to use; please don't resell or redistribute.
