Financial tools should earn your trust.

We separate each country's rules, version every financial data set, and explain the assumptions that matter beside the result rather than burying them in a footnote.

Fifteen calculators are live today across the US and UK — salary, paycheck, tax and pay-conversion tools — plus dedicated pages for the US states where our state figure is verifiably correct. More tools launch only once their rules, content and tests meet the same standard.
