Rates refresh from central-bank and provider feeds throughout the trading day. For travel cash and small purchases any intraday rate is fine; for large transfers, compare against your bank's sell rate, which adds 1–3% margin.
Banks add a spread plus flat fees on top of the mid-market rate shown here. A $1,000 transfer at 1% spread costs $10 more than mid-market — always compare the all-in received amount, not the headline rate.
Convert daily costs (hotel, food, transport) at the current rate, then add a 5–10% buffer for rate drift and card foreign-transaction fees (typically 2–3% unless your card waives them).
Fiat currencies only, at official market rates. Street rates in restricted economies differ substantially — this tool won't reflect those.
Amounts stay in your browser session. Rate lookups hit the provider API; amounts are not logged with queries.
