How this calculation works
Decimal arithmetic avoids binary rounding surprises. The rate is a user input, not a live quote. Fees, spreads, and settlement dates may change the amount you receive. Currency codes do not select a jurisdiction or a tax rule.
Destination amount = source amount × explicit rate; round once, half up, at the selected decimal places.
Your calculation, step by step
- Multiply the amount by the rate you entered.
- Round half up to 2 decimal places.
A worked example
100 USD at an explicitly entered 0.90 EUR per USD gives 90.00 EUR, before fees.
