Visa vs Mastercard Exchange Rates: Which Is Better Abroad?
CCW Editorial · 2026-10-26 · 7 min read
The network's rate is rarely the problem. Here's how Visa and Mastercard convert your purchase, and the three charges that actually decide what you pay.
When you pay with a card in another currency, three different parties can touch the price: the card network (Visa or Mastercard), the bank that issued your card, and sometimes the merchant's own payment provider. Travellers often ask which network has the better exchange rate. The honest answer is that the network rate is usually the smallest part of the cost. This guide shows how each piece works and how to check them yourself.
How Visa and Mastercard convert a purchase
Visa and Mastercard each set their own exchange rates for every currency pair they handle, every day. When you buy something in euros with a US card, the network converts the amount into dollars at its rate and passes the dollar amount to your bank. The rate is the one in force when the transaction is processed, which can be a day or more after you tap your card, so the amount on your statement may differ slightly from what you expected at the till.
Both networks publish their rates through free online calculators on their websites. You choose the currencies, the date and, if you like, a bank fee percentage, and the calculator shows what a purchase would convert to. They are the most reliable way to check a past transaction against what you were charged.
How close are the network rates to the mid-market rate?
The mid-market rate is the midpoint between wholesale buying and selling prices — the benchmark this site shows. Card network rates are wholesale rates set by the network, and for major currencies they are usually very close to it, typically within a fraction of a percent. Independent comparisons tend to find that neither network is consistently better: on a given day and pair, Visa may be a little ahead and on another day Mastercard will be. For everyday spending, the gap between the two networks is usually a few cents on a meal and a few dollars on a large hotel bill.
Choosing a card by network saves pennies. Choosing a card by its foreign transaction fee, and paying in the local currency, saves real money.
The charges that matter more
1. Your bank's foreign transaction fee
Your card issuer, not the network, decides whether to add a foreign transaction fee. On cards that charge one it is commonly up to 3% of every purchase in another currency, and some issuers apply it to purchases from merchants based abroad even when the price is in your own currency. Many travel cards, and some issuers on all of their cards, charge no foreign transaction fee at all. In the US the fee is shown on the card's pricing table under 'Foreign Transaction'.
2. Dynamic currency conversion at the till
Abroad, a card terminal or ATM may offer to charge you in your home currency instead of the local one. This is dynamic currency conversion (DCC), and the rate is set by the merchant's provider, not by Visa or Mastercard. DCC rates often include a margin of several percent. Unless you have checked the numbers, choose the local currency and let your card network convert it.
3. ATM and cash fees
Cash withdrawals can carry an ATM operator fee, an out-of-network fee from your bank and the foreign transaction fee on top. Credit cards usually treat cash withdrawals as cash advances, with fees and interest from day one. A debit card from a bank that refunds ATM fees, or a multi-currency account, is usually the cheaper way to get cash.
Worked example: a $1,000 week in Europe
Say you spend €920 on cards during a trip and the mid-market rate on the day is 1 EUR = 1.0870 USD, so the purchases are worth $1,000.04 at the mid-market rate. These numbers are illustrative; use the converter for today's rate.
- Network rate 0.2% above mid-market: €920 × 1.0892 = $1,002.06. Network cost: about $2.
- Add a 3% foreign transaction fee: $1,002.06 × 1.03 = $1,032.13. Fee: about $30.
- Accept DCC with a 5% margin instead of paying in euros: about $1,050.04 before any bank fee. Margin: about $50.
- Same spending on a no-foreign-fee card, paid in euros: about $1,002.06 in total.
The difference between the two networks would be a dollar or two either way. The difference between a 3% card and a no-fee card is about $30, and refusing DCC is worth about $50. That is where the savings are.
What about American Express and Discover?
American Express and Discover run their own networks and set their own conversion rates. Their rates work the same way, but acceptance abroad is narrower than Visa or Mastercard, especially for Discover and especially at small merchants. Carry a Visa or Mastercard as a backup if your main card is on another network.
How to check what you were charged
- Note the local-currency amount on the receipt and the date it posted to your account.
- Look up that date and pair in your network's online exchange rate calculator.
- Divide the amount you were charged by the local amount to get the rate you actually paid.
- Compare that rate with the mid-market rate for the same date. The difference, as a percentage, is your total cost; our exchange rate markup calculator does this in one step.
The short answer
Visa and Mastercard exchange rates are both close to the mid-market rate, and which one is better changes from day to day. Pick a card with no foreign transaction fee on either network, always pay in the local currency, and keep a second card on the other network in case a merchant or ATM rejects the first.
