Stop guessing what a sale will leave you. Type the price and your costs and see what you keep.

What’s inside:
• Profit Calculator: pick a platform, type the sale price, item cost and shipping. Get your fees, net profit, margin and ROI.
• Side-by-side table: the same item on every platform in your fee table.
• Max Buy Price: type what an item should sell for and the profit you want. Get the most you can pay.
• Fee Table you can edit, pre-filled for eBay, Poshmark, Mercari, Depop, Vinted, Facebook Marketplace and Whatnot.
• Quick-start guide.

How it works: download right after checkout, open in Excel or Google Sheets, type in the yellow cells and read the answer.

Good to know: works in Excel 2019 or newer, Microsoft 365 and Google Sheets. The fee rates are starting points from published 2026 fee guides. Platforms change them and they vary by category, country and seller level, so check the platform’s own fee page and edit the table. Not affiliated with any marketplace. Results depend on what you enter, with no profit promise.
