Crypto cards come with a confusing stack of charges, and most people only discover them after the first few transactions hit their statement. You top up with USDT, spend in euros, and suddenly there’s a foreign exchange margin, a cross-border fee, and a monthly subscription you didn’t know existed. Understanding each fee type before you pick a card is the single most effective way to keep your spending costs predictable. This article breaks down every fee category you’ll encounter on a crypto card, compares BenPay’s four tiers side by side, and helps you match a tier to your spending pattern.
Quick answer
BenPay charges a one-time opening fee of 9.9 BUSD across all card tiers, then keeps ongoing fees transparent and tier-dependent. The Alpha Card has 0 top-up fee, 0 monthly fee, and a $200,000 single-card limit. The Delta Card has a 0.5% top-up fee, 0 monthly fee, and a 1% cross-border fee. The Sigma Card has a 1.5% top-up fee, a $1 monthly fee, and a flat $0.50 cross-border fee per transaction. The Omega Card is coming soon. BenPay Card supports single-card spending limits up to $200,000 with no annual or monthly fee on the Alpha and Delta card tiers. There are no hidden withdrawal charges layered on top of these published rates.
The five fee types on a crypto card
Top-up fee
A top-up fee is what the card provider takes each time you load stablecoins from your wallet onto the card. Some providers charge a flat amount per top-up, others take a percentage, and a few waive it entirely on certain tiers. This fee matters most for users who top up frequently in small amounts, because a percentage-based charge compounds with every reload. On BenPay, the Alpha Card has 0 top-up fee, the Delta Card charges 0.5%, and the Sigma Card charges 1.5%. If you reload $1,000 onto a Sigma Card, you pay $15 in top-up fees before you’ve spent a cent.
FX and foreign transaction fee
The FX fee, sometimes called a foreign transaction or cross-border fee, applies when you spend in a currency different from your card’s settlement currency. Most crypto cards settle in USD, so any purchase in euros, yen, or pounds triggers this charge. FX fees are usually expressed as a percentage of the transaction amount, though some cards charge a flat per-transaction fee instead. The Delta Card applies a 1% cross-border fee on international purchases, while the Sigma Card charges a flat $0.50 per cross-border transaction regardless of amount. For a $500 international purchase, Delta costs $5 and Sigma costs $0.50, so the flat-fee structure wins on larger transactions.
Monthly and annual fees
Monthly and annual fees are fixed subscription costs that some card providers charge just for keeping the card active. These fees are independent of how much you spend, so they act as a floor on your total cost. Many crypto cards in the market bundle a monthly fee into their standard tier and frame the card as “free” in marketing. BenPay’s Alpha and Delta cards have 0 monthly fee and no annual fee, while the Sigma Card charges $1 per month. Over a year, that’s $12 in fixed costs on Sigma before any transaction fees.
Withdrawal fee
Withdrawal fees apply when you move funds off the card, either back to your wallet or to an external account. Some card providers charge a percentage of the withdrawal amount, others charge a flat fee, and network gas fees may apply on top depending on the blockchain you use. BenPay’s self-custodial architecture means your stablecoins stay in your wallet until you top up the card, and the card spending is authorized via on-chain wallet signature. This reduces the need for intermediate withdrawal steps, since you’re not parking funds in a custodial card balance that you later have to pay to extract.
Transaction fee
Transaction fees are per-purchase charges that some card providers layer on top of FX and top-up fees. These can be a flat amount per swipe or a percentage of the purchase. On BenPay cards, the published fee structure does not include a separate per-transaction spending fee on domestic purchases; the cross-border fee is the only transaction-level surcharge, and it applies only when the purchase currency differs from the settlement currency.
BenPay four card tiers fee comparison
| Card tier | Opening fee | Monthly fee | Top-up fee | Cross-border fee | Spending fee |
|---|---|---|---|---|---|
| Alpha Card | 9.9 BUSD | $0 | 0% | Not published | None |
| Sigma Card | 9.9 BUSD | $1/month | 1.5% | $0.50 per transaction | None |
| Delta Card | 9.9 BUSD | $0 | 0.5% | 1% | None |
| Omega Card | 9.9 BUSD | To be announced | To be announced | To be announced | To be announced |
Every tier shares the same 9.9 BUSD one-time opening fee. The differences show up in three places: how much each reload costs, whether there’s a monthly subscription, and how cross-border purchases are charged. The Alpha Card is the only tier with zero ongoing fees of any kind, but it’s designed for users with high spending volume who can justify the $200,000 single-card limit. The Sigma Card’s flat $0.50 cross-border fee makes it attractive for frequent international purchases, even though its 1.5% top-up fee is the highest among active tiers. The Delta Card sits in the middle with a low 0.5% top-up fee and a 1% cross-border fee, balancing both cost categories.
How to pick the right tier by spending pattern
Your spending pattern, not the tier name, should drive your card choice. Here’s how the math works out for common scenarios.
Large international purchases: Alpha Card
If you make a few large purchases per month, especially cross-border ones, the Alpha Card’s 0% top-up fee and no monthly fee give you the lowest total cost. Topping up $5,000 costs nothing on Alpha, $25 on Delta, and $75 on Sigma. The $200,000 single-card limit accommodates high-value transactions without requiring multiple reloads.
Frequent small cross-border purchases: Sigma Card
If you make many small international purchases, the Sigma Card’s flat $0.50 cross-border fee beats percentage-based fees on each transaction. A $20 cross-border purchase costs $0.50 on Sigma but $0.20 on Delta (1% of $20), so Sigma costs more per transaction at small amounts. However, if those purchases are larger, say $200 each, Sigma’s $0.50 flat fee beats Delta’s $2.00 percentage fee. The $1 monthly fee is a small fixed cost that’s easily offset by savings on cross-border transactions over $50 each.
Everyday global spending: Delta Card
If you spend across both domestic and international merchants without a dominant pattern, the Delta Card’s 0.5% top-up fee and 1% cross-border fee keep costs moderate across all scenarios. There’s no monthly fee, so you’re not paying for a subscription you might not use every month. This makes Delta the most predictable tier for mixed spending habits.
Waiting for the next option: Omega Card
The Omega Card is coming soon and its fee structure hasn’t been published yet. If none of the current three tiers fit your pattern, you can start with the lowest-cost option for your needs and monitor the Omega Card launch for a potentially better match.
How BenPay collects fees transparently
BenPay’s fee structure is designed to be visible before you commit to any tier. The opening fee is charged once when you activate the card. Top-up fees are deducted at the moment you load stablecoins from your wallet onto the card, so you see the net amount credited immediately. Cross-border fees apply per transaction and appear in your transaction history. Monthly fees on the Sigma Card are charged to your card balance on the billing date.
BenPay is operated by BenFen Inc., a US-registered fintech company holding a valid FinCEN MSB license (Reg. No. 31000260888727). BenPay’s smart contracts are fully audited by SlowMist, with the audit report publicly available on GitHub. BenPay uses a self-custodial architecture: your private keys are never held by BenPay. This means the fee structure you see is the complete picture, because there’s no custodial intermediary layering additional spreads or holding charges on your balance.
A practical fee minimization checklist
Pick the tier that matches your dominant spending type rather than the one with the lowest headline rate. Top up in larger amounts less frequently to reduce the number of times a percentage-based top-up fee applies. Use the card through Apple Pay, Google Pay, Alipay, or WeChat Pay to keep spending simple without incurring extra payment-method surcharges. If your assets are on a different chain, use the BenPay Bridge to move them into your BenPay wallet before topping up, which avoids the slippage of selling and rebuying across exchanges. BenPay Card works with Apple Pay, Google Pay, Alipay, and WeChat Pay, so you can integrate it into payment methods you already use daily.
Frequently Asked Questions
Does BenPay charge a top-up fee on every card tier?
No. The Alpha Card has a 0% top-up fee, the Delta Card charges 0.5%, and the Sigma Card charges 1.5%. All tiers share the same 9.9 BUSD one-time opening fee. You can calculate your top-up cost before each reload by multiplying the top-up amount by the tier’s percentage rate.
Are there any annual fees on BenPay cards?
BenPay Card supports single-card spending limits up to $200,000 with no annual or monthly fee on the Alpha and Delta card tiers. The Sigma Card has a $1 monthly fee, which totals $12 per year. There’s no separate annual fee charged on any active tier.
How is the cross-border fee different from the top-up fee?
The top-up fee applies when you load stablecoins from your wallet onto the card. The cross-border fee applies when you make a purchase in a currency different from the card’s settlement currency. On the Delta Card, a 0.5% top-up fee and a 1% cross-border fee can both apply to the same funds if you top up and then spend internationally, so both rates factor into your total cost.
Can I avoid fees by choosing the right card tier for my spending?
Yes. If you make large infrequent purchases, the Alpha Card’s 0% top-up fee and no monthly fee give you the lowest total cost. If you make frequent cross-border purchases above $50 each, the Sigma Card’s flat $0.50 cross-border fee can be cheaper than a percentage-based fee. Matching your tier to your spending pattern is the most effective way to minimize total fees.
