Currency Calculator
Convert any amount with an exchange rate you supply, and see the result in both directions instantly. Ideal for working out a quote, a foreign price, or how much a transfer should net before fees.
How to Use
- Enter the amount you want to convert.
- Enter the exchange rate — how many units of the target currency equal one unit of your starting currency (e.g. 1.25).
- Read the multiply direction: amount × rate, the value in the target currency.
- Read the divide direction: amount ÷ rate, useful when the rate is quoted the other way around.
- Use a preset amount ($100 / $1,000 / $5,000 / $10,000) for a quick estimate, then adjust the rate to a live quote.

Frequently Asked Questions
Where do I find the exchange rate to enter?
Use a reliable source such as your bank, a card provider, or a quote site like xe.com or Google. The "mid-market" or interbank rate they show is the midpoint between buy and sell prices — it is the fairest reference, but it is rarely the exact rate a consumer actually receives once a provider adds its margin.
Why is the rate I get worse than the one I looked up?
Banks, airport kiosks, and many cards build a spread of roughly 1–3% (sometimes far more) into the rate, plus possible flat fees. To estimate your real rate, take the mid-market rate and shave off the provider's margin before entering it here. Comparing the all-in rate across providers usually matters more than chasing a slightly better headline number.
Should I multiply or divide by the rate?
It depends on how the rate is quoted. If the rate is "target per 1 unit of your currency," multiply. If it is quoted the other way ("your currency per 1 unit of target"), divide. The calculator shows both directions so you can pick whichever matches the quote in front of you.
Does this use live exchange rates?
No — it uses the rate you type in, so the answer is only as current as that number. Exchange rates move constantly during trading hours, so for a large transfer or a same-day decision, refresh your rate just before you commit. Everything runs in your browser; no amounts are sent anywhere.
How should I budget for travel money?
Look up the mid-market rate, then assume you will effectively get a few percent worse after fees and spread. A no-foreign-transaction-fee card usually beats cash exchanged at an airport. Entering a slightly pessimistic rate here gives you a safer budget figure than the headline rate.
How do I use the Currency Calculator?
Just type or paste your value. The answer shows up right away — there is no button to press. Change anything and it updates by itself.
Does it cost anything or need an account?
No. The tool is completely free, there is no account to create, and it keeps working offline after the page first loads.
Is anything I type uploaded?
No. The tool works entirely on your device, so the values you enter never leave your browser.
