2026 Marketplace Seller Fee Calculator
Etsy, eBay, Amazon, Poshmark, Depop & more — see your real net payout
A marketplace seller fee calculator shows the exact amount a platform like Etsy, eBay, Amazon, or Poshmark deducts from a sale before it reaches your bank account. Marketplace fees typically run 6.5%–20% of the sale price depending on the platform, on top of payment processing fees of 2.6%–3%. This tool computes your net payout and true profit after fees, shipping costs, product cost, and ad spend — then ranks every major platform side by side for the same sale.
How Marketplace Fees Are Calculated
Most marketplaces charge fees in layers: a transaction/commission fee (a percentage of the sale), a payment processing fee (percentage plus a flat amount per order), and sometimes a flat listing fee per item. The fee base is usually the total amount the buyer pays, including shipping — not just the item price.
| Platform | 2026 Fee Structure |
|---|---|
| Etsy | 6.5% + 3% + $0.25 + $0.20 listing |
| eBay | 13.25% + $0.30 (most categories) |
| Amazon | 15% referral fee (varies by category) |
| Poshmark | 20% (flat $2.95 under $15) |
| Stripe / Square (own store) | ~2.9% + $0.30 |
Example: A $45 item with $6.50 shipping sold on Etsy generates $51.50 in total charges. Etsy's combined fee rate of roughly 9.75% plus $0.45 in flat fees comes to about $5.47, leaving a net payout of $46.03 before subtracting your product cost and shipping expense.
⚠️ Expert Pro-Tip
Fees are charged on shipping too — so "free shipping" isn't free. When you build shipping cost into the item price and offer "free shipping," the marketplace still takes its cut of that inflated item price, meaning you effectively pay fees on your own shipping cost twice: once when it's baked into the price, and again structurally since fee rates apply to the full charge. Price deliberately — test whether charging shipping separately or building it in nets you more after fees for your specific price point and platform.
