How do I know if I was actually charged DCC?

Last verified 22 August 2026 · by the NoDCC editorial desk

What does a DCC charge look like on a statement?

The rate is quoted and the currency is chosen before the authorisation request is even sent. Visa's rules then require the acquirer to enter the payment into interchange in the exact transaction currency you authorised, so if you accepted the home-currency offer, home currency is what arrives at your bank.

That is the tell. A DCC charge lands as a single amount in your own currency, and your own bank had nothing to convert. Decline the offer and the reverse happens: the transaction reaches the network in the local currency, and Visa converts it to your issuer's settlement currency using its own currency conversion rate.

Banks differ in whether they print the original local amount next to the charge, so a missing local figure is a hint, not proof. The proof is arithmetic, and it needs two numbers.

How do I work out the rate I actually paid?

You need what you were charged in your own currency, and what the purchase or withdrawal was in the local one. Divide the first by the second and you have the rate you were given.

Worked example

You withdrew 1,000 CZK in Prague on 1 April 2026. Suppose your statement shows EUR 43.45.

1. Divide: 43.45 ÷ 1,000 = 0.04345 euro per koruna, or 23.02 koruna per euro.
2. Find the reference rate. The Czech field test described below recorded the ECB rate that day as 24.514 CZK to the euro, so 1,000 CZK was worth EUR 40.79.
3. Divide the totals: 43.45 ÷ 40.79 = 1.065. You paid 6.5% over the reference rate.

Compare totals, not inverted rates. Setting 23.02 koruna per euro against a reference of 24.514 looks like a 6.1% gap, and 6.5% is the real cost. A percentage measured on a rate you have flipped upside down is not the same percentage.

Two things trip up the lookup. ECB reference rates are quoted against the euro, so if neither of your currencies is the euro, divide one euro rate by the other to get the cross rate. And the EU rule measures against the latest available ECB reference rates rather than the day's own rate; if your transaction fell on a weekend or a holiday and no rate is published for it, use the last working day before it and treat the answer as approximate.

Then check which day. Visa's dispute clock runs from the transaction processing date, which Visa defines as the date it accepted the interchange data, so the clearing date rather than the day you paid. If the transaction date's reference rate does not fit, try the settlement date's; the Czech field test compared both.

The calculator on the homepage does this arithmetic against the current ECB reference rate, so it fits an offer on the screen in front of you or a charge from the last day or two. It has no date field, so for an older charge look up that date's reference rate and divide by hand, as above.

How big does the gap have to be before it is a markup and not a bank fee?

Two different charges widen that gap, and they behave differently enough to tell apart.

Your issuer's fee is set by contract and written down. Visa requires an issuer to provide complete written disclosure of any fee that may be charged for an international transaction, and describes the underlying rate as one Visa selects from wholesale market rates, which the issuer may then adjust with an optional issuer fee or its own markup applied outside VisaNet. Read your agreement rather than inferring the number, and do not assume one number covers everything you do with the card: American Express publishes a 2.99% currency conversion fee in the UK alongside a separate cash withdrawal fee of 3% or GBP 3, and a 2% conversion commission on Hong Kong accounts.

A DCC markup is not a fee line on your statement. Visa's own merchant documentation states that the exchange rate used for the DCC service is a wholesale rate including a DCC markup, and the European Commission's 2018 impact assessment describes the DCC amount as the provider's foreign exchange reference rate plus a mark-up. It sits inside the rate: your issuer's statement will not break it out, and the only place either network requires it in figures is a Visa DCC receipt.

Ordinary rate spread is small, and the only benchmark we could source for it is old. In its 2011 study of airline booking sites, ECC-Net took 1.61% as its threshold, that being the largest gap it observed between the ECB, Visa and Mastercard rates themselves, and treated variation above it as hardly justifiable. That is 2011 fieldwork on a different channel, so use it as an order of magnitude rather than a current benchmark. On the scheme side, the Norwegian Consumer Council in 2017 described the payment cards' own standardised markup as 1.75%, and normal DCC as roughly four times that.

Whatever is left after your own bank is usually large. BEUC reported a 2016 Stiftung Warentest test in which 20 investigators withdrew cash in 13 non-euro countries and found that DCC raised the price paid by 2.6% to 12%, and by 2% to 5% on in-store payments. Stiftung Warentest's own 2019 test, 30 testers across 23 countries making 330 withdrawals and 132 card payments, found that accepting DCC would usually have cost more than 5%, peaking at 13.7%. The freshest measurement is Czech: in April 2026 Měšec.cz withdrew 1,000 CZK from ten Prague ATM networks on a euro-billed German card and measured markups over the ECB rate from 6.51% at Air Bank to 19.00% at ATM Point, on a single visit to each operator. Euronet, one of the tested operators at 15.00%, reproduced the same table on its own corporate site.

One number is contested and should not be averaged. BEUC reports a Norwegian study of 1,500 transactions as costing 7.6% more on average with a largest mark-up of 12.4%, measured against the official Visa rate. The Norwegian Consumer Council, describing what is evidently the same Sparebanken Vest work, gives 6.6%. Take them as 6.6% or 7.6% depending on whose account you are reading, not as one figure.

The practical cut is comparison, and it only works like for like: purchases against purchases, withdrawals against withdrawals. Your issuer's fee is one contracted number in a document you can read, so across comparable charges you can predict it. A DCC markup belongs to whoever owns the terminal, and the Prague test spread more than twelve percentage points across ten ATM operators. If the gap swings from ATM to ATM, or between an ATM and a shop, it is not coming from your bank.

What is a compliant DCC receipt supposed to show?

Both networks require a receipt. They do not require the same things on it, and the difference decides how much work you have to do yourself.

Visa

Table 5-34 of Visa's rulebook sets out what a DCC receipt must contain: the transaction amount with currency symbols in both the merchant's or ATM's local currency and the transaction currency; a label such as “Transaction Currency” or “Amount Charged” next to the amount; the currency conversion rate; the currency conversion commission, fees, markup or margin on the exchange rate over a wholesale or government-mandated rate; a statement, easily visible to you, that you were offered a choice of currencies and expressly agreed; and a statement that the conversion was conducted by the merchant, branch or ATM acquirer.

Read the fourth item again. A Visa DCC receipt has to show what the conversion cost you, as a commission, a fee, a markup or a margin over the wholesale rate. A receipt showing a rate and no conversion charge of any kind falls short of that, and so does one carrying no statement that you were offered a choice and agreed to it. The agreement half matters most, because express agreement is what the Visa dispute turns on.

Mastercard

Mastercard's receipt rule is shorter. Where DCC was chosen, the receipt must show the local-currency amount, the converted amount, the currency symbol or code of each, and the conversion rate used. The markup is not required on the receipt. Mastercard places it earlier instead: before authorisation you must be clearly informed that you have the right to choose the currency, along with both amounts, the conversion rate to be applied, and any other fee that can be charged if you select conversion.

So a Mastercard DCC receipt that shows a rate and no markup can be entirely compliant. To get the markup out of it, you do the division yourself.

Both Mastercard rules above come from its Transaction Processing Rules, read here in two editions, one dated 9 December 2025 and one dated 9 June 2026. Mastercard says of its own posted rulebooks that they will not always be absolutely current in all regards, so treat every network rule quoted on this page as checked on 22 August 2026.

Three further limits, stated because the page would mislead without them. Article 4(6) switches the protections off where the payment service user is not a consumer, so a corporate card may sit outside them. Whether the rule also requires the conversion provider or your bank to be established in the Union turns on the territorial scope of PSD2, which Article 4 cross-refers to and which we have not verified. And a foreign webshop is outside the part that matters at a checkout: Article 4(1) addresses payment service providers generally, but the duty to display the mark-up on the spot is written for a party providing conversion at an ATM or at the point of sale, and online purchases appear only in a recital of the original 2019/518, which is interpretive rather than binding. A separate PSD2 duty, Article 59(2), transposed in the UK by regulation 57 of the Payment Services Regulations 2017, does cover conversion offered by the payee and requires all charges plus the exchange rate to be disclosed before the transaction is initiated. How that duty applies to a checkout outside the EU we have not verified.

What if I no longer have the receipt?

Under both networks the receipt matters less than you would expect, because once a dispute is filed it is the merchant's side that has to prove you agreed. Getting the dispute filed is the separate problem: your bank will ask you for supporting evidence first.

Mastercard's chargeback guide splits currency errors into two conditions. Both need something from you: a cardholder letter, email, message or a completed Form 1240. For the second condition, where the conversion was performed incorrectly, one further document is required, and the receipt is only one of three that will do; a billing statement or an issuer statement of the billing currency also satisfies it. A no-consent claim does not strictly require the receipt at all. Mastercard then goes further on consent disputes: the acquirer cannot second-present, and terminal logs are expressly not a valid defence.

Visa puts the receipt burden on the other side too. The issuer supplies a certification that you did not agree to DCC and did not make an active choice; it is the acquirer and merchant that must produce either the local-currency receipt or evidence that you expressly agreed, plus certification that the DCC selection is made electronically by the cardholder and cannot be made by the merchant. Visa's merchant-facing guidelines say the same thing from the merchant's chair: to defend the case, the merchant needs evidence that you actively chose DCC and a copy of the transaction receipt.

Rebuild the two numbers from what survives. The home-currency amount is on your statement. The local amount is on the menu, the price tag, the hotel folio, the booking confirmation, or the withdrawal amount you keyed into the machine yourself. That pair is close to what a Mastercard compliance case for an ATM outside Europe actually asks for: a cardholder statement specifying the currency you expected, and an issuer explanation of how the claim amount was calculated using the exchange rate in effect on the transaction date.

One useful default if a slip turns up with no currency on it: under Mastercard's rules, where no currency is identified on the transaction receipt, the transaction is deemed to have taken place in the currency that is legal tender at the point of interaction.

What do I do next if the numbers say I was converted?

Proving a markup and recovering it are different problems. Be clear-eyed about the second.

Your bank is not obliged to raise a chargeback. The UK Financial Ombudsman Service, writing about card disputes generally rather than about DCC, states that a bank or lender does not have to raise one, that chargebacks can fail, that it is not always reasonable to raise one at all, and that your bank will ask for supporting evidence before starting. Outside the UK the position varies, and nothing in either network's rules gives a cardholder a direct right to file. Revolut, which publishes the clearest issuer statement on DCC, says it can raise a dispute chargeback where you rejected the conversion and it was applied anyway. Can, not will. Visa's own consumer page stops at telling you to decline the offer and report the incident to your card issuer, and promises nothing after that.

The scheme deadlines below are your bank's windows for filing into the network. They are not your deadline: yours sits in your card agreement, is usually shorter, and is measured from a different event, so report the charge as soon as you spot it.

• Visa. Dispute Condition 12.3, Incorrect Currency, covers DCC that occurred where you did not expressly agree, or where you were refused the choice of paying in local currency. The dispute applies for the entire transaction amount, within 120 calendar days of the transaction processing date. At pre-arbitration the amount is limited to the difference between the original amount and what you should have been charged.
• Mastercard. The route is the currency errors condition under message reason code 4834. The issuer charges back only the difference, within 90 calendar days of the central site business date, or 120 calendar days for intra-European and inter-European ATM and Maestro transactions.
• Mastercard ATMs outside Europe. The 4834 chargeback covers ATM cases only where a Europe-issued card was used at an ATM in Europe. Everything else runs through a pre-compliance case and then a compliance case, filed before 120 calendar days from the central site business date or settlement date have passed.

In the United States the separate statutory route is a poor fit. Chase tells cardholders they typically have 60 days from the statement date to dispute an unauthorised charge, and that a Fair Credit Billing Act billing-error inquiry must be sent within 60 days of the first bill containing the error; its page does not mention currency conversion at all, and a DCC charge is one you authorised. Regulation Z's list of billing errors covers a computational or similar error of an accounting nature made by the creditor, not being charged in a currency you did not choose by a merchant. Treat the network dispute as the operative route.

One thing not to ask for, at least on Mastercard: switching DCC off. Mastercard's DCC guide states that issuers cannot control whether DCC is performed on a transaction, and that blocking it would prevent card acceptance and violate Mastercard Standards. We found no equivalent Visa statement in either direction. The exceptions are product-level. Acquirers are barred from offering DCC on prepaid travel cards and on multi-currency debit cards, narrowed in the 2026 processing rules to card-present transactions, and Visa bars it on cards enabled with the Visa Multi-Currency Solution and on travel prepaid cards including Visa TravelMoney.

What to do about it

Working order, from a statement in front of you:

1. Get both numbers and divide. Home-currency charge divided by local-currency amount gives the rate you were given. The calculator compares it against the current ECB reference rate; for an older charge, look that date's rate up and divide by hand.
2. Subtract your own bank. Find your foreign transaction fee in your card agreement; Visa requires your issuer to have disclosed it in writing. Check whether withdrawals are priced differently from purchases before you blame anyone else, and see the withdrawal breakdown for the separate charges stacked inside a cash withdrawal.
3. Compare like with like. Purchases against purchases, withdrawals against withdrawals. A contracted issuer fee is predictable across comparable charges; a gap that swings from ATM to ATM is not your bank, and the Prague test found 6.51% to 19.00% across ten operators on one card in one city.
4. Photograph the receipt if you still have it. A Visa DCC receipt is required to show the conversion charge and a statement that you were offered a choice and agreed, so a receipt carrying neither is non-compliant on its face. That is corroboration; the dispute itself turns on whether you agreed.
5. Raise it with your issuer at once, naming the route. Visa Dispute Condition 12.3 within 120 calendar days of the transaction processing date, or Mastercard reason code 4834 within 90 days of the central site business date, 120 for intra-European and inter-European ATM and Maestro. Those are your bank's filing windows, not yours; yours is in your card agreement. The refusal and recovery guide has the full escalation ladder.
6. Then make it moot. Visa says declining will not affect your ability to make purchases or withdraw cash internationally, and under Mastercard's rules a transaction where you do not choose your billing currency is processed in the local one. Print the refusal card in the local language, and check the country page for where you are going next.
