Fee Guides & Explanations
The calculators on this site answer "how much is the fee on this amount?" — these guides answer the question behind it: how does this platform actually charge, and where does the money go? Every guide uses the same rates as the calculators, checked against each platform's own published pricing and stamped with the date they were last verified (November 2026). Each one ends with the calculator that does the maths for your own figures.
