Frequently Asked Questions
Answers to common questions about how exchange rates work, how often they update, and how they compare to bank and money transfer rates.
How often are exchange rates updated on this site?
Exchange rates come from the Frankfurter API, which surfaces reference rates published by the European Central Bank. The ECB refreshes these once per Eurozone business day, typically around 16:00 CET, so the rate you see reflects the latest published reference rate rather than a continuously traded intraday value.
Is the rate shown the rate I'll get at my bank?
Not exactly. The published reference rate is the wholesale interbank mid-market rate. Banks, card networks, and money transfer providers add a spread (often 1–4% for retail FX) on top of it, so the effective rate you receive will differ. The reference rate is still the most neutral benchmark for comparing providers.
What happens when the live API is unavailable?
If the live fetch fails, we display the last exchange rate that was successfully fetched and cached in your browser, clearly labelled with the date it was captured so you know it may be stale. On your very first visit during an outage with no cached rate available, we show a notice and disable conversion until a successful fetch occurs.
Which currencies are supported?
All currencies published by the European Central Bank reference rate set — over 30 world currencies including USD, EUR, GBP, JPY, CHF, CAD, AUD, KRW, INR, CNY, and more.
Do I need to sign up or pay to use this converter?
No. The converter is free to use, requires no account, and runs entirely in your browser. The conversion is performed client-side after fetching the latest reference rate.
Why does the chart only go back one year?
The chart uses Frankfurter time-series data, which offers a flexible historical range. The 1M, 6M, and 1Y selectors cover the most common planning horizons without making large data requests that slow down the page.
