Exchange rates change by the minute, so any currency converter that bakes in a fixed rate is stale the moment it's published. This converter instead takes the exchange rate you provide — from your bank, card statement, or a live rate source you trust — and applies it precisely, with a full step-by-step solution.

How it works

Enter the amount, select the source and target currencies, and enter the exchange rate (how many units of the target currency one unit of the source currency buys). The converter multiplies the amount by that rate.

  1. Enter amount.
  2. Enter from currency.
  3. Enter to currency.
  4. Enter exchange rate (1 unit of "from" = ? units of "to").
  5. Click Calculate to see your results.

Examples

Converting 100 USD to EUR

With an exchange rate of 0.92, 100 USD converts to 92 EUR.

Who should use it

  • Converting a price or budget between currencies while traveling or shopping internationally.
  • Converting invoice or income amounts between currencies for accounting purposes.

Industry applications

  • International finance and accounting
  • E-commerce and cross-border retail

Advantages

  • Always accurate to whatever exchange rate you provide, with no risk of stale built-in rates.
  • Works for any currency pair, not just a fixed preset list.

Limitations

  • Requires you to supply the current exchange rate yourself rather than looking it up automatically.

Common mistakes to avoid

  • Entering the exchange rate backwards (target-to-source instead of source-to-target), which inverts the result.
  • Using a stale exchange rate from an old statement instead of the current rate.

Best practices

  • Always use the most current exchange rate available for time-sensitive conversions, since rates can shift meaningfully within a single day.

Tips

  • For recurring conversions, bookmark this page and simply update the exchange rate field each time you use it, since only the rate changes day to day.

Frequently asked questions

Yes, with no signup and no limit on how many conversions you run.
Exchange rates fluctuate constantly throughout the day, so a rate hardcoded into a tool would quickly become inaccurate — entering your own rate (from your bank, card provider, or a live rate feed) keeps the conversion accurate to the rate you're actually working with.
Your bank, card statement, or any live currency rate provider will show the current rate between two currencies — enter that value directly into this calculator.
No — this calculates a pure mathematical conversion at the rate you enter; banks and card providers often add a margin or fee on top of the market rate, so your actual charged amount may differ slightly.
