What Profit is a free set of UK marketplace fee calculators for sellers. Calculate eBay fees, compare marketplace fees, and check buyer protection fees before you list. Get a clearer estimate of your take-home amount without building a spreadsheet.
I built What Profit because marketplace fees can make a sale look more profitable than it really is. Sellers should be able to check the numbers quickly, before committing time or pricing too low.
The first tools cover eBay fees, marketplace fee comparisons, and buyer protection fees for the UK. They’re free to use, and I’m building this around real seller questions and feedback.

If you spot a missing marketplace, an incorrect assumption, or a useful improvement, I’d genuinely like to hear from you.
