How to work out your profit on a sale
- Pick your marketplace to load its typical fees, or choose Custom.
- Enter your sale price, any shipping you charge the buyer, what the item cost you, your actual postage and any other costs.
- Adjust the fee fields if your category or plan differs. Your net profit, margin and return update instantly.
How marketplace fees usually work
Most selling platforms take a cut in up to three parts: a marketplace fee (a percentage of what the buyer pays), a payment processing fee (another percentage, sometimes bundled into the first), and a fixed fee per order or per listing. Many platforms charge their percentage on the total the buyer pays — including the shipping you charge — which is why the shipping toggle matters.
Which figures does each preset use?
- eBay — a final value fee on the order total plus a small per-order fee. Payment processing is bundled into that percentage.
- Etsy — a transaction fee, a separate payment processing percentage and fixed fee, and a small per-listing fee.
- Depop — no marketplace selling fee on US sales; you mainly pay payment processing.
- Mercari — a selling fee plus payment processing.
- Poshmark — a flat fee on small orders and a percentage above a threshold; the preset uses the percentage, so check small orders manually.
- Vinted — the buyer pays the buyer-protection fee, so the seller typically keeps the full price.
Margin vs. return on cost
Profit margin is your net profit as a percentage of what the buyer pays — useful for comparing sales of different sizes. Return on cost is your net profit divided by what you spent (item, shipping and other costs) — useful when you buy to resell. The break-even price is the sale price at which profit would be zero, given your current costs and fees.
