Most providers advertise "zero commission" while quietly inflating the exchange rate by 2-8%, costing you hundreds on larger transactions. Enter the rate you were offered and see exactly how much you are overpaying.

How to Use the Currency Exchange Fee Calculator
Every time you exchange currency, you likely pay a hidden fee disguised as a "slightly different" exchange rate. This currency exchange fee calculator exposes exactly how much extra you are paying by comparing the rate you were offered against the true mid-market rate. The difference is pure profit for the exchange provider.
Step 1: Select Your Currencies
Choose the currency you are converting from and the currency you are converting to. The calculator supports 24 major world currencies. For example, if you are exchanging US Dollars to Euros, select USD as the source and EUR as the target.
Step 2: Enter the Amount
Enter the total amount you are exchanging in the source currency. This is used to calculate the actual fee in both currencies and the annual cost if you make this type of exchange regularly.
Step 3: Get the Mid-Market Rate
Click the "Look Up Rate" button to fetch the current mid-market rate from the European Central Bank. This is the fairest reference rate, the same one used by financial institutions and shown on Google. You can also enter a rate manually if you know it from another source.
Step 4: Enter the Rate You Were Offered
Enter the exchange rate quoted by your bank, airport kiosk, currency exchange booth, or online service. This is the rate that determines how much of the target currency you actually receive. The difference between this rate and the mid-market rate is the hidden markup.
Step 5: Review the Results
The calculator reveals the markup percentage, the fee in both currencies, what you should receive versus what you actually receive, and the annual cost if you make this exchange monthly. A rating from "Fair" to "Ripoff" helps you instantly assess whether the offered rate is reasonable.
How to Get Better Exchange Rates
To minimize exchange rate markups, use fintech services like Wise or Revolut that offer near mid-market rates. Avoid airport and hotel exchanges, which typically add 5-12% markup. If using a bank, negotiate the rate for larger amounts. For credit card purchases abroad, use a card with no foreign transaction fee. Always compare rates from multiple providers before exchanging significant amounts.
Frequently Asked Questions
Is this currency exchange fee calculator free?
Yes, this tool is completely free with no limits or signup required. You can check as many exchange rates as you want. All calculations run locally in your browser and no financial data is sent to any server.

What is the mid-market rate?
The mid-market rate is the midpoint between the buy and sell prices for a currency pair on the global foreign exchange market. It is the fairest exchange rate and the one you see on Google or financial news sites. Banks and exchange services add a markup above this rate to make a profit.
What is a fair exchange rate markup?
A markup below 0.5% is considered fair and is typical of services like Wise and Revolut. Markups between 0.5% and 1.5% are acceptable for most retail exchanges. Anything above 1.5% is expensive, and markups over 3% should be considered a ripoff. Airport kiosks and hotel exchanges often charge 5-10% or more.
How do I find the rate I was offered?
Check your bank statement, the exchange receipt, or the rate displayed at the currency exchange counter or website. For credit card transactions abroad, look at the conversion rate shown on your statement. You can also ask the provider directly what exchange rate they are applying before completing the transaction.
Where does the mid-market rate data come from?
Mid-market rates are fetched from the Frankfurter API, which sources its data from the European Central Bank. Rates are updated daily on business days. These are the same reference rates used by banks and financial institutions worldwide.
Why do banks and exchange services charge a markup?
Banks and exchange services add a markup to the mid-market rate as their primary revenue source for currency conversion. This covers their operating costs and profit margin. The markup varies widely: online services like Wise add 0.3-0.6%, while traditional banks may add 2-4%, and airport kiosks can add 5-12%.
Does this tool account for fixed fees as well?
This tool focuses specifically on the exchange rate markup, which is the most common hidden fee. Many services also charge a fixed transaction fee on top of the rate markup. To get the total cost, add any flat fees charged by your provider to the markup cost shown by this calculator.
