Why use Sellerkeeps
Every fee in one place. A sale loses money in more than one way: the percentage, the fixed fee, shipping, ads and payment processing. Each calculator lists them all so you can see where the money goes.
Work backwards from your profit. Enter the profit or margin you want and get the lowest price that reaches it, plus the break-even price below which you lose money.
Rates you can check. Each page says when its rates were checked and links to the platform’s own fee page.
Questions people ask
Is Sellerkeeps free?
Yes. Every calculator is free to use, with no signup and no limits.
Where do the fee rates come from?
From each platform’s own published US fee page. Every calculator page states the date the rates were last checked and links to the source.
Is anything I enter sent to a server?
No. The calculators run in your browser, and the prices and costs you type in stay on your device.
Are the results exact?
They are estimates based on the standard published rates. Your account can differ, for example through negotiated rates, other currencies or fees that are not listed, so treat the result as a close guide.
