Numbers you can check

Most free calculators never say where their rates come from. Ours always do.

1

Official sources

Rates come from the European Commission, the Canada Revenue Agency and GOV.UK, and are cited on every page.

2

Dated and verified

Each dataset shows when we last checked it. If the data hasn't been re-verified recently, the page says so.

3

Formulas shown

Every tool documents its formula with a worked example, so you can check the arithmetic by hand.
