Scope note

This page uses a live reference FX rate, then applies the percentage fee you enter as a direct deduction from the converted amount. Some real providers charge through spread markups, transfer fees, or both, so treat this as a transparent estimate rather than a guaranteed bank quote.

Frequently asked questions

Where do the exchange rates come from?

This calculator requests live reference rates from Frankfurter's free exchange-rate API, which documents official and central-bank-backed provider coverage.

How is the bank charge applied?

The tool models the bank charge as a percentage deduction from the converted amount. Some banks instead widen the exchange spread or add a flat fee, so your provider's final quote may differ.

What does the effective rate mean?

The effective rate is the final received amount divided by the source amount after the percentage fee is deducted.
