Conversion is the largest component and the most avoidable, settling into a local currency account and converting in bulk removes 20,160 a year for the cost of holding the account. The international card fee is not avoidable.
How the Foreign Transaction Cost Calculator works
The international card fee is not avoidable; the conversion cost mostly is. Settling into a local currency account and converting in bulk removes it for the cost of holding the account, which at any real volume is a rounding error.

The layers of cost on a cross-border payment
A single foreign card payment can carry four separate costs, and only some appear on any statement you see.
The interchange fee, which is higher for cross-border transactions than domestic ones and can be several times higher for cards issued outside the region. The scheme fee, also higher cross-border. The acquirer margin. And the currency conversion, wherever it happens in the chain.
The result is that a foreign card payment frequently costs two to three times a domestic one. A seller with a 1.4% blended domestic rate can be paying 3.5% or more on international cards, and the blended figure on their statement hides which is which.
Finding out what you are actually paying
Interchange-plus pricing shows the components separately and is the only structure where the cost is visible. Blended pricing gives one rate for everything and hides the fact that international transactions cost more.
Most small merchants are on blended pricing because it is simpler and it is what gets offered. Asking for a breakdown by card type and region is usually possible and frequently revealing.
The number to extract is the effective rate on international transactions specifically. If international is 20% of volume at 3.5% and domestic is 80% at 1.4%, the blended rate is 1.8% and the international portion is costing more than twice what anyone assumes.
Local acquiring, which changes the arithmetic
A transaction is cross-border if the acquirer and the issuer are in different regions. Acquiring locally in the market where your customers are converts those transactions to domestic, at domestic rates.
The saving is substantial: often 1% to 2% of the transaction value, plus better authorisation rates, because issuers decline foreign transactions more readily than domestic ones. The authorisation improvement alone can be worth several percent of revenue in markets where decline rates are high.
The cost is complexity. Local acquiring usually requires a local entity or a payment provider that offers local acquiring on your behalf. Several do, and for a seller with meaningful volume in a single foreign market the arithmetic is usually clear.
Declines, which cost more than fees
Cross-border transactions are declined more often than domestic ones, and each decline is a lost sale rather than a fee. Decline rates on international card payments can run several points above domestic, which dwarfs the fee difference.
The causes are mostly issuer risk rules: an unfamiliar merchant in an unfamiliar country triggers a fraud rule. Some of it is addressable through better data quality on the transaction, some through local acquiring, and some is simply the issuer's policy.
Retry logic helps and needs care. Retrying a declined transaction immediately usually fails again and can look like card testing, which is worse. Retrying after a delay, and offering an alternative payment method after a decline, recovers a meaningful share and costs nothing but the implementation.
Choosing the currency to charge in
Charging in the customer's local currency converts better and shifts the conversion cost to you. Charging in your own currency avoids the conversion and leaves the customer facing their card issuer's foreign transaction fee, typically around 3%, which they will see on their statement.
The conversion lift from local currency pricing is well documented and frequently in the double digits, which usually exceeds the conversion cost by a wide margin.
The exception is markets where the customer base is accustomed to paying in dollars or euros regardless. Business customers in particular often prefer a familiar currency to a converted one. Testing rather than assuming is the answer, and it is a genuinely testable question since both options can run concurrently to different traffic.

Frequently asked questions
What does accepting foreign payments cost?
An international card fee of around 1% to 1.5%, a currency conversion cost of 1% to 4%, and payout fees per transfer. The conversion is usually the largest and the most avoidable.
What is a local currency account?
An account holding balances in the currency you were paid in, so conversion happens when you choose rather than automatically per transaction.
When is it worth opening one?
Once monthly foreign revenue makes the conversion saving exceed the account cost, usually at a few thousand a month, which is lower than most people assume.
Can I avoid the international card fee?
No. It reflects genuinely higher interchange on cross-border transactions and applies regardless of how you settle.
