Curated for finance & accounting

Built for finance — real-time rates, accurate calculators.

Convert currencies and crypto at real-time rates, work out VAT/GST, model loans and mortgages, project compound interest, and convert salaries to any cadence.

Why this set

Finance work demands accuracy: a rounding error in a salary calculation or VAT figure is a credibility problem. We pull live FX rates from the European Central Bank, use exact decimal arithmetic for money math (no floating-point drift), and show every formula so you can sanity-check the result against your own model — useful when you need to defend a number in a meeting.
