Crypto Payment Gateway Fees Compared — Who's Really the Cheapest?

Transaction fees are the number you see on every gateway's homepage. But they are not the only cost. Setup fees, monthly charges, withdrawal fees, fiat conversion markup, and minimum payment thresholds all eat into your margins. This comparison breaks down the real cost of accepting crypto through each major gateway — at three different volume levels.

Fee Types Explained

Before comparing, understand what you are actually paying for:

• Transaction fee: A percentage taken from each payment. This is the primary cost. Ranges from 0% (BTCPay Server) to 1% (BitPay, CoinGate, BoomFi).
• Setup fee: One-time cost to create your merchant account. Good news: every gateway on this list offers free setup.
• Monthly fee: Recurring charge for access to the platform. Most gateways are free. Some (like NOWPayments and BoomFi) offer premium tiers with additional features.
• Withdrawal fee: Cost to move your earnings from the gateway to your wallet. Usually just the blockchain network fee (a few cents to a few dollars depending on the chain).
• Fiat conversion fee: If the gateway converts crypto to USD/EUR for you, they charge for it. Typically included in the transaction fee for gateways that offer this (BitPay, CoinGate, BoomFi, CoinsPaid).
• Network fees: Blockchain transaction costs paid by the sender (your customer). Not charged by the gateway, but worth understanding — high-fee chains like Ethereum mainnet can cost $5-20 per transaction during congestion.

Fee Comparison Table

*BTCPay Server is free software, but you pay ~$10-30/month for VPS hosting.

Total Cost at Different Monthly Volumes

Transaction fees only tell part of the story. Here is what each gateway actually costs at $1,000, $10,000, and $50,000 monthly volume. We include hosting costs for self-hosted options and estimate 2 withdrawals per month for custodial gateways (assuming ~$1 average network fee per withdrawal on efficient chains).

Hidden Costs to Watch For

1. Withdrawal Minimums

Some custodial gateways require you to accumulate a minimum balance before withdrawing. If you process low volume, your funds could be locked for weeks. NOWPayments and Plisio both have withdrawal thresholds. Non-custodial gateways (Coinremitter, PayGate.to, ATLOS, Paymento, BTCPay) do not have this issue because payments go directly to your wallet.

2. Exchange Rate Markup

When a customer pays in BTC and you receive USDT, the gateway performs a conversion. The exchange rate used may include a markup over the market rate. Most gateways do not disclose their exact rate source. This is difficult to quantify but can add 0.1-0.5% in hidden costs.

3. Network Fee Timing

Blockchain network fees fluctuate wildly. A Bitcoin withdrawal that costs $0.50 on a quiet Sunday can cost $5-10 during network congestion. Ethereum can be worse. If you withdraw frequently on expensive chains, network fees can exceed the gateway's transaction fee on small payments.

4. CoinsPaid's Custom Pricing

CoinsPaid does not publish transparent pricing. Their 0.8% rate is a baseline — actual costs depend on volume, contract terms, and whether you use fiat settlement (1% additional). Request a detailed quote before committing.

Cheapest Gateway by Volume Tier

Under $5,000/month

Winner: Coinremitter (0.23%, no KYC, non-custodial)

At low volume, hosting costs make BTCPay Server more expensive than Coinremitter's 0.23% fee. Coinremitter is the cheapest option until your volume exceeds roughly $6,500/month.

$5,000 - $50,000/month

Winner: BTCPay Server (0%, ~$15-20/month hosting)

Once your volume crosses ~$6,500/month, BTCPay's fixed hosting cost becomes cheaper than any percentage-based fee. At $50K/month, you save $100-$480/month compared to hosted alternatives.

Over $50,000/month

Winner: BTCPay Server (by a wide margin)

At high volume, the 0% fee makes every competitor look expensive. If you process $100K/month, even a 0.2% fee costs $200/month — BTCPay costs $20. The only reason to use a hosted gateway at this volume is if you need features BTCPay lacks (300+ altcoin support, subscription billing, fiat settlement).

Need fiat settlement?

Winner: BitPay or CoinGate (both 1%, fiat conversion included)

If you must receive USD, both BitPay and CoinGate include the crypto-to-fiat conversion in their 1% fee. CoinsPaid can be cheaper at high volume with negotiated rates, but requires a sales call and full KYC.

Frequently Asked Questions

What is the cheapest crypto payment gateway?

BTCPay Server is free (0% transaction fee) but requires self-hosting. Among hosted solutions, XAIGATE (0.2%) and Coinremitter (0.23%) are the cheapest.

Are there hidden fees with crypto payment gateways?

The main "hidden" costs are withdrawal network fees, exchange rate markup on currency conversions, and withdrawal minimums that lock your funds. Non-custodial gateways avoid most of these since payments go directly to your wallet.

Is a 1% crypto payment fee good?

It is better than credit cards (2.5-3.5%) but expensive compared to crypto-specific alternatives. Gateways charging 1% (BitPay, CoinGate, BoomFi) typically include fiat settlement, which justifies the premium if you need it. If you do not need fiat, 0.2-0.5% options are available.

Do I pay fees on refunds?

Policies vary. Most gateways do not refund the original transaction fee. You pay the fee on the initial payment and then pay network fees to send the refund. BTCPay Server refunds are free (minus network fees) since there was no fee to begin with.

How do crypto gateway fees compare to PayPal and Stripe?

PayPal charges 2.9% + $0.30 per transaction. Stripe charges 2.9% + $0.30. The cheapest crypto gateways (0-0.5%) save you 2-3% per transaction. On $10,000/month, that is $200-$300 in savings.
