Selling on platforms like Etsy, Amazon, or eBay gives you instant access to millions of buyers, but their complex fee structures can quickly drain your profits if you aren't careful. The Marketplace Fee Calculator takes the guesswork out of platform selling by calculating exactly how much you get to keep after all platform cuts are taken.
The calculator applies standard platform fee logic: it subtracts the percentage-based referral fee (which varies by category) and any fixed transaction fees (like a $0.30 payment processing fee) from your total selling price. This reveals your true net payout and your adjusted profit margin. By factoring in your original cost of goods, you can see if selling a particular item on a specific marketplace is actually worth your time, or if the fees are eating too much into your bottom line.
Marketplaces charge you for the privilege of accessing their customer base. These fees often include a percentage-based referral fee (usually 8-15%) plus payment processing fees (usually 2.9% + $0.30). These fees come directly out of your gross profit, which significantly lowers your final adjusted margin.
Many sellers use a strategy called 'channel pricing,' where they set slightly higher prices on marketplaces like Amazon or Etsy to offset the fees, while keeping prices lower on their direct-to-consumer website to encourage direct sales.
Most marketplaces calculate their payment processing fee on the total transaction amount, which includes the item price, shipping costs, and often the sales tax paid by the buyer. This means you are slightly penalized for charging high shipping rates.
