Convert amounts across currencies with transparent rate assumptions.
Overview
Currency conversion matters for travel, cross-border shopping, and international business payments. Small differences in exchange rate and fees can materially affect final converted value.
This calculator converts between base and target currencies using your chosen rate input. It can also account for conversion fee percentages to show net proceeds.
Rates move continuously and provider spreads vary, so treat outputs as planning estimates and confirm live quotes before transactions.
Steps
Choose the pair you want to convert.
Input the money amount in base currency.
Use current provider or market rate assumption.
Apply spread or service fee percentage.
Review gross and net conversion outputs.
Test alternate rates and fee structures.
Math
Converted amount = Source amount x exchange rate x (1 - fee rate)
The base amount is multiplied by the quoted exchange rate to get gross conversion, then adjusted downward by any transaction fee or spread.
Worked cases
1,000 x 0.92
€920 gross conversion.
920 x (1 - 0.015)
€906.20 net after fee.
Compute net outcomes under both assumptions
