Rates are requested when you calculate. No fixed live-rate result is shown here; read the rate date in your actual result.
The method, explained
Net source amount = amount × (1 − fee ÷ 100) − fixed fee. Estimated received amount = net source amount × reference rate.
With 100 USD, a 2% fee and a 1 USD fixed fee, 97 USD remains. At an illustrative 0.90 rate, the recipient gets 87.30 EUR.
What to keep in mind
Fees are deducted before conversion. Negative net amounts are rejected. A provider’s exchange-rate markup or a fee in the target currency needs a different model.

Common questions
Does this include a bank’s hidden rate markup?
No. The rate is an ECB reference rate. Enter known fees and compare with the provider’s actual final quote.
What information is sent to the rate provider?
Only the currency pair and requested date. Amounts, fees and comparison prices stay in your browser.
