Profit

Revenue is easy to see and profit is easy to overestimate. This hub breaks down the numbers that sit between the two: marketplace commissions and buyer-paid fees, shipping and return costs, promotion spend, currency conversion, and the DAC7 reporting thresholds that apply across the EU. Fee facts are taken from official marketplace pages and dated, because they change often. Use it together with the calculators to see what a flip really earns.
