Frequently Asked Questions

How fresh are the rates?

Hourly from the server when online (12 quick-pick majors pinned above a searchable full list of 160+). Offline, the same 12 convert from labeled fallback rates — the UI says so. For large transfers, compare against your bank's sell rate, which adds 1–3% margin.

Why does my bank show a different rate?

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.

How do I estimate a trip budget?

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).

Does it handle crypto or street rates?

Fiat majors only, at hourly-cached server rates with a labeled offline fallback. No crypto, and street rates in restricted economies differ substantially — this tool won't reflect those.

Is my conversion history stored?

Amounts and recent history stay in your browser (localStorage). Rates themselves come from the server on demand — hourly-cached — with the 12-major fallback when that's unreachable.
