What Exchange Rate Do You Get When Paying With a Crypto Card?

When you pay with a crypto card, you can meet up to two exchange rates. The first turns your crypto into regular money, and it is set by the card provider or its partner, such as a rate on the provider’s own trading platform or the card network’s rate. The second applies only when you pay in a foreign currency, and on cards such as Coinbase’s it is set by the card network that processes the payment. Either step can come with a fee on top, so the rate alone does not tell you the full cost.

This guide explains where each rate comes from, how issuers describe theirs, and how to see what you actually paid.

Rate 1: Crypto Into Regular Money

Every crypto card has to turn crypto into the currency of the card at some point. Where that happens depends on the card.

• At top-up, for prepaid cards. On a prepaid card, the conversion usually happens when you load the card. NORA CARD, for example, converts your crypto top-up into a USD balance, according to the official site as summarised on our NORA CARD page. After that, you spend dollars, not crypto.
• At the till, for wallet-linked cards. MetaMask says its card converts your tokens into local currency at the moment of purchase, at Mastercard’s rates, and that these rates are calculated at the time of the transaction.
• From an exchange account. Coinbase’s cardholder agreement, filed with the US Consumer Financial Protection Bureau with an effective date of September 2022, says your spending balance is turned into US dollars at the rate then current on Coinbase’s own trading platform.

How each provider describes its rate, as of October 2026:

Because these rates are set differently, the same purchase can cost slightly different amounts of crypto on different cards.

Rate 2: Foreign Currency

If you pay in a currency other than the one your card is held in, there is a second conversion. Coinbase’s cardholder agreement explains how this works for its US card: the card network or card association that processes the transaction converts the amount into the card’s currency. According to the agreement, the network uses one of two rates: a rate it chooses from those available on wholesale currency markets, which can differ from the rate the network itself gets, or a rate set by a government where one is required. The agreement adds that this rate is separate from any fee the issuer charges.

In other words, on that card the foreign currency rate comes from the card network, not from the crypto company.

Fees That Sit on Top of the Rates

The rate is only part of the cost. Fees can be added at either step.

There can also be costs on the crypto side. MetaMask’s page says its conversion has no additional MetaMask fees in one answer but mentions a minimal per-transaction fee in another, so check its fees table. Coinbase’s cardholder agreement notes that separate Coinbase currency conversion fees may apply under its wallet terms. Our crypto card fees guide lists the other charges to check.

When Your Coin’s Price Moves

If you spend a coin whose price changes, the amount of crypto taken depends on the price at the moment of conversion. On a wallet-linked card, that is the moment you pay. On a prepaid card, it is the moment you top up, and after that your balance is in regular money.

Stablecoins work differently. Visa explains that stablecoins are built to keep a steady value by being tied to a reserve asset, for example a regular currency, so the crypto-to-money step involves less movement.

A Worked Example

Say you buy a meal abroad that costs the equivalent of $50 on a US card with a 3% foreign transaction fee, which is what Crypto.com’s US page lists for its Midnight, Ruby, Jade and Indigo cards, as of October 2026. The local price is first converted into dollars. The issuer then adds 3%, or $1.50, so the meal costs about $51.50 in card balance.

If the same card balance was loaded from crypto, there was also a conversion when you topped up. On a wallet-linked card, the crypto would instead be converted at the moment of the purchase. Each step is small on its own, but together they decide what the meal really cost you.

Why Two Cards Can Charge Different Amounts

Because each provider sets its crypto rate differently, and each card has its own foreign transaction fee, the same purchase can come out at different prices. A card with a higher fee but a better crypto rate may cost about the same as a card with no fee and a wider margin. The only way to know is to look at what each step costs for the way you pay.

How to See the Rate You Actually Got

1. Open the transaction in the card app for the amount charged in your card’s currency and, for wallet-linked cards, the crypto taken.
2. Compare with the price at the time to estimate the crypto conversion cost.
3. Look for a separate FX fee line on foreign purchases.
4. Read the issuer’s rate wording in its terms or FAQ, since each describes its rate differently.

Questions and Answers

Is the crypto card exchange rate the same as the market price? Not necessarily. Each provider uses its own source, such as its trading platform or the card network’s rate, and fees can apply on top.

Who sets the rate when I pay abroad? For the foreign currency step, the card network that processes the transaction, according to Coinbase’s cardholder agreement.

Does a stablecoin avoid exchange rate costs? It reduces price movement in the crypto step, but foreign currency rates and fees can still apply.
