A Traveler's Guide to Currency Conversion & Exchange Rates

Published on September 20, 2025

Whether you're planning an international trip, shopping online from a foreign store, or sending money to family abroad, you'll need to deal with currency conversion. Understanding exchange rates is key to making sure you get the most value for your money.

What is an Exchange Rate?

An exchange rate is simply the value of one country's currency in relation to another country's currency. For example, if the exchange rate between the U.S. Dollar (USD) and the Euro (EUR) is 0.92, it means that 1 USD is worth 0.92 EUR. These rates fluctuate constantly based on a variety of economic and geopolitical factors.

Understanding the "Spread"

When you exchange currency at a bank or a currency exchange booth, you'll notice they have a "buy" rate and a "sell" rate. The difference between these two rates is called the spread, and it's how these services make a profit. The "mid-market rate" is the real exchange rate without this spread, which is what our calculator uses to provide an accurate conversion.

How to Calculate Currency Conversions

The math is simple multiplication or division:

• To convert your home currency to a foreign currency: Multiply your home currency amount by the exchange rate.
• To convert a foreign currency back to your home currency: Divide the foreign currency amount by the exchange rate.

Tips for Getting the Best Exchange Rate

1. Avoid Airport Kiosks: They typically have the worst exchange rates and highest fees due to convenience.
2. Use a Credit Card with No Foreign Transaction Fees: This is often the cheapest way to make purchases abroad, as you get a rate very close to the mid-market rate.
3. Withdraw from Local ATMs: Using your debit card at a local ATM abroad usually offers a much better rate than exchanging cash. Be aware of any fees your bank may charge.
4. Monitor the Rates: Before you travel, keep an eye on the exchange rates. If you see a favorable rate, it might be a good time to exchange some cash.

Conclusion

A little bit of planning can save you a significant amount of money when dealing with foreign currencies. By understanding how exchange rates work and using the right tools, you can ensure you're not paying more than you have to for your international transactions.
