Crypto debit card fees: what spending USDT really costs (with calculator)

Every fee in one table

Here's the complete list for all three ExCards cards, taken from the public fee disclosure. These are all the fees ExCards publishes. The card issuer reserves the right to add fees, including FX, depending on the card's country of issue and the transaction currency.

Rates as of October 10, 2026

One detail catches people out. The top-up fee is taken from what you send, so at 3.5% a 100 USDT top-up leaves 96.50 on the card. To have exactly $800 available, you need to send about 829.02 USDT.

Fee changes are announced in app.excards.io at least 30 days before they take effect.

Calculate your own cost

Enter the card, your top-up amount, how many purchases you make and the share of spending in non-USD currencies. The calculator uses the same fee rules as the table above.

The FX line in the calculator shows the maximum. Your real markup can be lower and is visible on each transaction.

Three worked examples

These are estimates built on the published fees. We assume a 3D Secure check on every Visa purchase, which is the most expensive case, and we gross up each top-up so the balance covers the spending. The mandatory 10 USDT doesn't count, since it stays on the balance. For simplicity, 1 USDT is counted as $1.

1. Freelancer paid in USDT, Visa E-commerce. Twelve subscriptions and services plus everyday purchases add up to 40 transactions and $800 a month, all billed in USD.

• Top-up needed: 829.02 USDT, of which 29.02 is the 3.5% fee
• Authorizations: 40 × $0.03 = $1.20
• Monthly cost: $30.22, or 3.78% of spending
• First month with the 35 USDT card price: $65.22

2. Small business, 40 payments of about $500. That's $20,000 a month for contractors, SaaS and ad accounts.

• Top-up needed: 20,725.39 USDT, fee 725.39
• Mastercard Business: 40 × $0.50 = $20 in authorizations, $745.39 a month (3.73%)
• Visa E-commerce on the same payments: $1.20 in authorizations, $726.59 a month (3.63%)

On fees alone, Visa costs $18.80 less here. Mastercard Business earns its place once a single payment goes above $20,000, the Visa's per-transaction limit. The Mastercard allows up to $250,000 per transaction.

3. Living in euros, Visa E-commerce. Someone who has relocated spends the equivalent of $1,000 a month across 30 purchases, all charged in EUR.

• FX markup, worst case: 2% of $1,000 = $20
• Top-up needed to cover spending plus FX: 1,056.99 USDT, fee 36.99
• Authorizations: 30 × $0.03 = $0.90
• Monthly cost: up to $57.89 (5.79%). The same spending billed in USD would cost $37.17 (3.72%)

That gap is the FX markup plus the 3.5% top-up fee charged on it. If a merchant lets you choose the billing currency, it can make a noticeable difference.

Visa's tiered fee or Mastercard's flat $0.50: which is cheaper?

On authorization fees, Visa E-commerce is cheaper per purchase in every normal case. A purchase of $1 or more costs at most $0.03 (the 3D Secure check). A purchase under $1 costs $0.10, plus $0.03 if 3DS runs. Mastercard Business charges $0.50 every time.

There's no break-even point on authorizations. The choice comes down to limits. Visa E-commerce allows up to $20,000 per transaction with no daily or monthly cap. Mastercard Business allows $250,000 per transaction, $500,000 a day and $1,000,000 a month.

Visa Universe also charges a flat $0.50 per authorization, like Mastercard Business, but its top-up fee is 2% instead of 3.5%, and it allows $1,000,000 per transaction. It has no offline POS payments.

The Visa's one weak spot is declines. If more than 10% of the card's authorizations are declined, a $0.80 surcharge applies. Frequent failed charges, like retrying a card that keeps getting rejected, are the most direct way to raise your Visa costs. A side-by-side of all three cards is on the card comparison page.

Are "free" crypto cards really free?

Sometimes, but a card with no issuance fee still has to earn money somewhere. The cost usually shows up in one of these places:

• Conversion. A spread when crypto becomes fiat, or an FX markup that isn't printed as a percentage.
• Top-up or load fees. These can be charged separately from spending.
• Monthly or inactivity charges. Sometimes they only start after a period of not using the card.
• Conditions. Fee-free tiers can depend on holding or locking a token.

ExCards earns from two things: the card price and the top-up fee (2% on Visa Universe, 3.5% on Visa E-commerce and Mastercard Business). We don't claim the card is free.

A related point: this is a debit-style card. You spend what you've topped up, and there's no credit line and no cashback. If you're weighing that against crypto rewards credit cards, this breakdown of credit and debit crypto cards explains the trade-offs.

How to keep your costs down

The top-up fee is a percentage, so splitting top-ups doesn't lower it. What you can control:

1. Top up less often, in larger amounts, sized to the spending you have coming up. The network fee is charged per transfer. Four small sends mean four network fees for the same money.
2. Pick a network with a lower network fee and check the address network before you send. This comparison of TRC-20, ERC-20 and BEP-20 goes through the differences.
3. Keep declines low. Keep enough balance for upcoming charges, and don't keep retrying a merchant that rejects the card. Approval is always the merchant's and processor's decision.
4. Pay in USD when you're given the choice. It avoids the issuer's FX markup of up to 2%.
5. Keep only near-term spending on the card. The card balance is held by the issuing partner. The rest of your USDT can stay in your own wallet.

Where these fees make sense

For people paid in USDT, people who have relocated without a local bank, and businesses with regular online spending, a card like this can handle most day-to-day payments. That includes subscriptions, services, groceries through Apple Pay or Google Pay, and contractor invoices. The trade-off is about 3.6–3.8% on USD spending in the examples above, plus network fees, and up to about 5.8% when everything is billed in another currency. There's no cash withdrawal, and cards don't work inside sanctioned countries.

If those numbers work for you, here's how to get a card and what it costs to start. Limits and top-up networks are also on the USDT card page.

How we checked this

Every ExCards number on this page was checked against the public fee disclosure as of 15 September 2026. The example arithmetic was recalculated from those fees. For a neutral view of where exchange rates sit on a given day, the ECB publishes daily euro reference rates (for information only, not a transaction rate). The issuer may apply additional fees depending on the card's country and the transaction currency. Updated 10 October 2026.
