FAQ

Why is my bank rate different?

Banks and card networks often apply a spread and/or fees. This calculator typically uses a reference rate from a data provider.

Does this update while I type?

Amounts can update instantly, but the page URL does not change while typing. Use Share Link to generate a restore URL.

What if I’m offline?

If caching is enabled and you’ve fetched rates before, the tool can use the last-known rate (clearly labeled) until you refresh online.
