Crypto Card Fees Explained: The 7 Charges That Decide Your Real Cost

Every crypto card advertises one number. Your actual cost is the sum of up to seven. This guide lists all of them, explains when each applies, and gives you a formula to compare any two cards honestly in about five minutes.

1. Conversion fee

Charged when your crypto is converted to the merchant currency. Ranges from 0% on stablecoin-native cards to about 2.5% on some exchange cards. This is the single biggest driver of cost for regular spenders because it applies to every transaction.

2. FX markup

Applied when the merchant currency differs from your card currency, typically 0–3%. It stacks on top of the conversion fee. Two cards with identical conversion fees can differ by hundreds a year for a frequent traveller.

3. ATM withdrawal fee

Usually a free monthly allowance followed by a percentage or flat fee, plus whatever the ATM operator charges. Cash-heavy users should treat this as a primary criterion — see our travel card guide.

4. Issuance fee

One-off, often €0–50. Virtual cards are usually free; physical cards and metal tiers cost more. It matters less than recurring charges but distorts short-term comparisons.

5. Monthly or plan fee

Premium tiers charge a subscription in exchange for better cashback or FX terms. Only worth it above a clear spending threshold — calculate the break-even before upgrading.

6. Inactivity fee

The most overlooked charge. Some issuers deduct a monthly amount after 3–12 months of no activity. If you keep a backup card, this quietly drains the balance.

7. Top-up and load fee

Charged when funding the card, either as a percentage or per transfer. Cards funded directly from an exchange balance often avoid it; cards funded by bank transfer or another card often do not.

The formula

Annual cost = (monthly spend x 12 x conversion %) + (foreign spend x 12 x FX %) + (ATM withdrawals x 12 x ATM cost) + issuance + (monthly fee x 12) - (cashback earned).

Worked example

$1,500 monthly spend, 20% of it abroad, $200 monthly ATM use:

• Card A: 2.49% conversion, 0% FX, free ATM up to $200 → about $448 a year.
• Card B: 0% conversion on stablecoins, 2% FX, 1% ATM → about $96 a year.

The cheaper card is not the one with the better cashback headline. It is the one whose fee structure matches your spending pattern.

Red flags in card terms

• "Up to X% cashback" with no visible tier table.
• FX fee described only as "market rate plus a margin".
• No published inactivity policy.
• Cashback paid in a volatile platform token with a lock-up.
