Most comparisons of crypto payment gateway fees stop at the headline percentage, which is the least useful number in the calculation. A provider advertising 0.5% can cost a merchant more per order than one charging 1%, depending on how it handles conversion, withdrawals and network selection.
This breakdown covers every cost layer in a crypto payment, how they compare against card processing, and how to calculate what an order actually costs you rather than what the pricing page suggests.
The Three Costs Behind Every Crypto Payment
A crypto payment involves three separate charges. They are levied by different parties, and only some of them appear on a pricing page.
Gateway Service Fee
This is the provider’s own charge, usually a percentage of transaction value. Flat-rate models — a single percentage on every transaction regardless of asset, size or geography — are the easiest to forecast. Tiered models that vary by volume or coin look cheaper at the top tier and rarely are in practice.
What matters is whether the percentage is the only charge. A 0.5% fee combined with a 2% conversion spread is a 2.5% fee with extra steps.
Blockchain Network Fee
This is paid to the blockchain, not the gateway, and it is the cost most merchants forget to model. It varies by network by two orders of magnitude.
Critically, in a direct-to-wallet setup the *customer* pays this fee when they send the transaction. It does not come out of your revenue — but it absolutely affects your conversion rate. A customer facing a $12 network fee on a $40 order frequently abandons the checkout.
Conversion and Withdrawal Costs
The third layer is where advertised pricing and real cost diverge most sharply.
• Conversion spread — converting crypto to fiat or between assets rarely happens at mid-market rate. A 1–2% spread is common and often undisclosed.
• Withdrawal fee — custodial processors charge to move your own balance out, sometimes a flat amount, sometimes a percentage.
• Minimum withdrawal thresholds — money below the threshold sits in the processor’s account until you accumulate enough.
• Payout network fee — the transfer out costs a network fee too, paid by you this time.
A merchant on a custodial processor at “0.8%” once mapped their real cost: 0.8% service fee, 1.5% conversion spread, a $25 flat withdrawal, plus the network fee on the payout. On $10,000 of monthly volume across four withdrawals, the effective rate was just over 3% — higher than the card processing they left.
Crypto Fees vs Card Processing Fees
The comparison is only fair when both sides include everything.

For a standard low-risk retailer, card processing at 2.9% and a good crypto gateway at 1% are closer than the table suggests, because cards deliver higher conversion. For high-risk merchants facing reserves and elevated rates, the gap is substantial and permanent.
How Network Choice Changes Your Margin
The network your customers use changes the economics of small orders more than any other single factor.
Stablecoin Transfer Costs by Network
|
Network |
Typical USDT transfer cost |
Settlement time |
|
BNB Smart Chain (BEP-20) |
~$0.03–0.05 |
~1 second |
|
Tron (TRC-20) |
~$2 (≈$4 to a new address) |
~1 minute |
|
Ethereum (ERC-20) |
~$3–15 |
~13 minutes to finality |
*Figures current as of September 2026. Tron costs roughly double when sending to an address that has never held USDT, because the network charges for creating the token account.*
The practical consequence:
• Orders under $50 — offer BEP-20 prominently. A $4 fee on a $30 order is a conversion problem.
• Orders $50–500 — TRC-20 works well and is what most customers already hold.
• Large B2B invoices — the network fee is immaterial; choose for finality and counterparty familiarity.
Simply reordering the network options at checkout so the cheapest appears first measurably improves completion on low-value carts.
Hidden Costs Merchants Forget to Budget
Five costs rarely appear in any comparison but show up in the accounts.
1. Volatility exposure between invoice and confirmation. If you accept Bitcoin and hold it, the value can move before you convert. Accepting stablecoins removes this entirely.
2. Reconciliation labour. Matching on-chain transactions to orders takes time unless your gateway passes your order ID through to the callback. Without it, expect hours of manual work monthly.
3. Underpayment write-offs. Customers routinely send slightly less because their exchange deducted a withdrawal fee. A tolerance policy converts a support ticket into a small, predictable cost.
4. Refund network fees. Every refund is a new on-chain transaction you pay for.
5. Failed or wrong-network payments. Support time, and occasionally unrecoverable funds if you do not control the destination keys.
How to Estimate Your Real Cost per Order
Work it out with your own numbers rather than the pricing page:
1. Take your average order value.
2. Add the gateway’s service fee percentage.
3. Add any conversion spread if you convert to fiat.
4. Add withdrawal costs divided by the number of orders per withdrawal cycle.
5. Add an allowance for underpayment tolerance — 0.1–0.3% of volume is realistic.
6. Compare the result against your current card processing including chargebacks and reserves.
The structural advantage of a non-custodial model is that steps 3 and 4 are zero. With no intermediary balance, there is no conversion and no withdrawal — funds settle directly to the merchant’s wallet.
Bcon Global uses exactly this structure: a flat 1% service fee with no withdrawal charge and no conversion spread, because payments go straight from customer to merchant wallet across Bitcoin, Ethereum, Solana, Tron and BNB Chain plus major stablecoins. For a merchant, that makes the real cost per order equal to the advertised rate — which is rarer than it should be.
FAQ
What is a typical crypto payment gateway fee?
Between 0.5% and 1% for the service charge. Anything advertised below that usually recovers the difference through conversion spreads or withdrawal fees.
Who pays the blockchain network fee?
In a direct-to-wallet setup, the customer pays it when sending. You pay network fees only on refunds and on moving your own funds.
Are crypto payments cheaper than credit cards?
On headline processing, usually yes. The full picture depends on your risk category — for high-risk merchants facing reserves and elevated rates, the saving is large; for standard retail, it is modest.
Can I avoid conversion fees entirely?
Yes, by settling in the asset the customer sent. Accepting stablecoins means you receive dollar-denominated value with no conversion needed.
How do I reduce network fees for my customers?
Support low-cost networks and present them first. Moving typical small-order volume from ERC-20 to BEP-20 or TRC-20 removes several dollars per transaction from the customer’s cost.
Final Thoughts
The advertised percentage is a starting point, not an answer. The real cost of accepting crypto is the service fee plus conversion, plus withdrawal, plus the reconciliation time and the write-offs nobody budgets for.
Model all five against your own order profile. In most cases the structure that wins is the simplest one — a flat fee with direct settlement, where there is no second layer for a cost to hide in.
