How our tools work
Every calculator uses a standard formula, written out on its own page next to a worked example run by the same code the tool uses. Nothing you type is sent to us or saved in your browser. And no broker pays to change a result: we may earn a commission when you open an account through our links, but that never touches the maths or our ratings. See how we make money.
None of the calculators reads our broker records. They work on the figures you enter, the conventions of each instrument (its pip size and contract size) and a set of dated reference exchange rates. A converted figure is an estimate at those rates, not a quote, because your broker converts at its own rate.
The broker filter is the exception: it reads the records behind our reviews when the site is built, so the company, licence and funding facts it shows are the ones on each review. It does not rank on our review scores, and a partner broker never ranks above an equal match.
