Look up the mid-market rate (e.g. on your central bank’s website) and compare it with what your bank offers. Card payments abroad often carry a 2–3% foreign transaction fee; choosing to pay in the local currency usually gives a better rate than “dynamic currency conversion”.
How to use the Currency Converter
- Amount
- Exchange rate (target units per 1 unit)
- Bank fee or spread
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter the amount, the exchange rate (units of the target currency per 1 unit of your currency) and any fee or spread.
Tips
- Enter figures for the same period and in the same currency.
- Exchange rates and prices change constantly – update them before you rely on a result.
- Use results as estimates and confirm important figures with the official source.
- Everything runs in your browser – try different values to compare scenarios.
Common mistakes to avoid
- Mixing gross and net figures.
- Using outdated rates.
- Treating rules of thumb as exact.
Inputs explained
| Field | What to enter |
|---|---|
| Amount | A number |
| Exchange rate (target units per 1 unit) | A number |
| Bank fee or spread | In % |
What each result means
- Converted amount = [Amount]×[Exchange rate (target units per 1 unit)]×(1 – [Bank fee or spread]÷100)
- At the rate without fees = [Amount]×[Exchange rate (target units per 1 unit)]
- Cost of the fee (target currency) = [Amount]×[Exchange rate (target units per 1 unit)]×[Bank fee or spread]÷100
- Reverse rate (units per 1 target unit) = 1÷[Exchange rate (target units per 1 unit)]
Example values
How the main result changes when Amount changes and everything else stays at the example values above:
| Amount | Converted amount |
|---|---|
| 50 | 14,025 |
| 75 | 21,037.5 |
| 100 | 28,050 |
| 125 | 35,062.5 |
| 150 | 42,075 |
| 200 | 56,100 |
Formula
Converted amount = amount × exchange rate × (1 − fee)Reverse rate = 1 ÷ exchange rateCost of the fee = amount × rate × feeWorked example
Inputs — Amount: 100; Exchange rate (target units per 1 unit): 280.5; Bank fee or spread: 0 %.
Results — Converted amount = 28,050; At the rate without fees = 28,050; Cost of the fee (target currency) = 0; Reverse rate (units per 1 target unit) = 0.003565.
