Foreign transaction fee calculator
Cards add two costs to purchases in another currency: a visible foreign-transaction fee (often ~3%) and an invisible exchange-rate markup. See what a purchase — or a year of them — really costs.

what a 0% FX card would save you
Tip: when a card terminal abroad offers to charge you in your home currency ("dynamic currency conversion"), decline it — paying in the local currency almost always gets a better rate.
Spotting these fees on your statement
They appear as separate lines like NON-STERLING TRANSACTION FEE or INTL SERVICE FEE, usually right after the purchase. Upload a statement and StatementDecoder totals them for you automatically — most people are surprised by the yearly figure.
The three costs hiding in a foreign card payment
First, the foreign-transaction fee: typically 1–3% added by your card issuer on non-domestic-currency purchases — the number this calculator surfaces. Second, the exchange-rate margin: your network converts at a wholesale-ish rate, but some banks add their own spread on top. Third — and usually worst — dynamic currency conversion (DCC): the terminal offers to charge you in your home currency 'for convenience', at a rate that commonly costs 3–8% more than letting your card network convert.
The one-line rule that saves the most money abroad: when a terminal or ATM asks 'charge in your home currency?', always choose the local currency. On your statement, DCC shows up as a suspiciously round home-currency amount and often a conversion note in the descriptor.
Reading FX charges on your statement
Foreign transactions typically show the original amount and currency alongside the converted amount, with any fee either baked into the rate or listed as a separate line (often 'NON-STERLING TRANSACTION FEE' or similar). Statement analysis flags these fee lines automatically and totals them for the period — travellers are frequently surprised what a two-week trip cost in fees alone. If you travel regularly, a no-foreign-fee card usually pays for itself in one trip.
Cards with no foreign transaction fee — and how to check yours
Foreign transaction fees are avoidable, and increasingly are. Many travel-focused credit cards, most challenger and neobank accounts (Revolut, Wise, Monzo, Chime and similar), and a growing number of standard debit cards charge nothing on overseas or foreign-currency purchases. The way to check yours isn't the marketing page — it's the terms, or a quick look at last year's statement for a line that scales with your spend abroad.
One trap survives even a fee-free card: dynamic currency conversion, the 'do you want to pay in your home currency?' prompt at a foreign terminal or checkout. Saying yes hands the exchange rate to the merchant's processor, usually at a markup worse than any fee you just avoided. Always choose to be charged in the local currency.
Frequently asked questions
What's a typical foreign transaction fee?
1–3% of the purchase, charged by your issuer. Many travel-oriented and fintech cards charge 0% — the calculator shows what your current card's rate costs on a trip.
What is dynamic currency conversion and why avoid it?
DCC is the terminal offering to bill you in your home currency at the merchant's conversion rate — commonly 3–8% worse than your network's rate, on top of any issuer fee. Always pay in the local currency.
Do foreign fees apply to online purchases?
Yes — if the merchant settles in a foreign currency, the fee applies even though you never left home. Some overseas merchants price in your currency; then DCC economics apply instead.
How do I see what I paid in FX fees last year?
Upload your statements to the analyzer — it detects and totals foreign-transaction and conversion-fee lines across the period, per statement and combined.
Which cards have no foreign transaction fees?
Many travel credit cards and most challenger banks and money apps (Revolut, Wise, Monzo, Chime and similar) charge no foreign transaction fee, and some standard debit cards don't either. Confirm in your card's terms rather than the ad copy.
Do I get charged a foreign fee for buying from a US website in my own currency?
Sometimes — the fee is triggered by where the transaction is processed and the currency, not where you're sitting. A purchase billed in a foreign currency or routed through a foreign bank can attract the fee even from home; your statement will show it as a separate line or a marked-up amount.
