Marketplace fees
What is a marketplace fee calculator?
A marketplace fee calculator shows what you keep from a sale after each marketplace takes its fees, so you can compare Poshmark, Mercari, eBay, Depop, Whatnot, Etsy and Grailed before you list. Type a sale price and what the item cost you, and the list above ranks all 7 by payout.
Marketplaces charge in different ways. Some take one percentage of the sale. Others add a payment processing fee, a fixed fee per order or a listing fee, and some charge on shipping and sales tax too. That is why the same $40 sale leaves you anywhere from $32.00 to $38.23.
The list uses default settings for a US seller with no shipping. For shipping, categories, other countries, boosts or ads, open the calculator for that marketplace. They all run on the same fee rules, checked against each marketplace’s own fee page on November 10, 2026.

What is the Marketplace Fee Calculator by Sidekick Tools?
A free calculator that shows your fees and payout on all 7 marketplaces for the same sale, ranked from highest payout to lowest, with a link to a detailed calculator for each one.
Why should I calculate fees before listing products?
Fees decide how much of the price you keep. With default settings, the fees on a $40 sale range from $1.77 to $8.00, so knowing them helps you set a price that still leaves a profit.
Are the fee calculators accurate for each marketplace?
Every Sidekick Tools fee calculator uses fee rules checked against the marketplace’s own fee page on November 10, 2026. They use the standard public rates, so eBay Store rates and Whatnot’s lower rates for high-volume sellers are not included.
Do these calculators include shipping and taxes?
The Mercari, eBay and Depop calculators include shipping, and the eBay calculator also counts sales tax because eBay charges its fee on it. The comparison on this page assumes no shipping. None of the calculators include income tax.
Can these calculators help me set the right listing price?
Yes. Enter a price and your item cost to see your profit on every marketplace at once. On a $40 item that cost $12, profit ranges from $20.00 to $26.23 depending on where it sells.
Which marketplace has the lowest fees?
With default settings, a US seller pays the least on Depop, $1.77 on a $40 sale, because Depop charges no selling fee in the US. Poshmark costs the most at $8.00, because it takes 20% of sales of $15 or more.
Are Sidekick Tools' fee calculators free to use?
Yes. Every fee calculator on Sidekick Tools is free and works in your browser.
