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.
