For a closer look at the topic, consider crypto payment gateway lowest fees btcpay alongside the options and criteria discussed below.
Choosing a crypto payment processor comes down to one thing: how much of your revenue stays yours. Transaction fees, currency conversion spreads, withdrawal costs, and hidden charges add up fast when you’re processing hundreds or thousands of payments monthly. This guide breaks down the real cost structure of four popular options — NOWPayments, BTCPay Server, CoinGate, and Cryptomus — so you can pick the one that actually keeps fees low.
The landscape has shifted significantly. Self-hosted solutions now compete with managed platforms on price, while every provider has adjusted their fee tiers as competition intensifies. Understanding where each solution saves money and where it costs more requires looking beyond headline percentages.
NOWPayments
NOWPayments positions itself as a non-custodial payment processor with a flat 0.5% fee across all supported cryptocurrencies and fiat on-ramps. That rate applies uniformly regardless of transaction volume, which makes cost forecasting straightforward for small to mid-sized merchants.
The platform supports over 100 cryptocurrencies and offers both fixed-rate and floating-rate checkout modes. Fixed-rate locking protects buyers from price volatility during the payment window, while floating rates follow live market prices. Settlement goes directly to the merchant’s wallet — NOWPayments never holds funds, which removes counterparty risk entirely.
Withdrawals through NOWPayments carry no additional platform fee since the funds never touch a central custody account. However, blockchain network fees (miner fees) always apply when moving funds off-chain. Currency conversion, when needed, runs at approximately 1% spread above mid-market rates.
For merchants already comfortable managing their own wallets, NOWPayments delivers one of the simplest fee structures available. The 0.5% base rate is competitive against most managed gateways, though high-volume operators may find better deals elsewhere.
BTCPay Server
BTCPay Server operates on an entirely different model: it’s open-source, self-hosted software with zero processing fees from the platform itself. There is no per-transaction charge, no monthly subscription, and no hidden markup. The only costs come from external sources — your hosting infrastructure and Bitcoin network fees when settling on-chain.
This approach appeals to merchants who prioritize sovereignty and cost control above all else. By running your own node or connecting to an existing one, you eliminate the middleman entirely. Payment confirmation times depend on your chosen settlement layer; Lightning Network settlements are near-instant and cost fractions of a cent, while on-chain Bitcoin transactions incur variable miner fees.
The trade-off is technical complexity. BTCPay Server requires server setup, maintenance, security hardening, and ongoing updates. You handle chargeback protection, compliance considerations, and integration work yourself. For developers and technically inclined teams, this overhead pays off quickly. For others, the time investment may outweigh the fee savings.
When BTCPay Server Makes Sense
Self-hosting becomes the clear winner when you process consistent daily volume, have development resources available, or operate in jurisdictions where open-source payment infrastructure aligns with regulatory expectations. Merchants using Lightning Network for smaller transactions effectively pay nothing per payment beyond hosting costs.
Cost Comparison Table
| Provider | Base Fee | Withdrawal Fee | Currency Conversion | Monthly Minimum |
|---|---|---|---|---|
| NOWPayments | 0.5% | None (non-custodial) | ~1% spread | None |
| BTCPay Server | 0% | Network fees only | Depends on router | None |
| CoinGate | 1% | Free (crypto/SEPA) | 1% exchange fee | None |
| Cryptomus | 0.5% | Free | Included in rate | None |
CoinGate
CoinGate charges a flat 1% transaction fee on its Standard plan, with no monthly fees or minimum volume requirements. The Enterprise tier offers custom volume-based pricing that negotiates downward as processing volume increases. Every plan includes access to 10+ cryptocurrencies and payment acceptance in 180+ countries.
CoinGate’s value proposition centers on convenience rather than raw cost efficiency. The platform handles fiat conversion automatically, offering instant settlement in EUR, GBP, or USD through its volatility shield feature. This means you receive stable currency payouts without managing crypto exposure, which matters for businesses that need predictable accounting.
Withdrawals via crypto or SEPA transfers are free on both plans. SWIFT withdrawals carry a 0.50% fee with a 50 EUR minimum. Manual currency conversions within the platform cost an additional 1%, though automatic checkout conversions don’t trigger this charge. Refunds between different currencies incur a 0.25 EUR + 0.1% conversion fee.
Crypto payouts through CoinGate cost 0.50 EUR + 0.5% per transaction, which adds up if you’re sending frequent small payments. For larger, less frequent disbursements, the flat euro component becomes negligible.
CoinGate works well for merchants who want a hands-off approach with fiat settlement, plugins for major e-commerce platforms, and support from a regulated entity operating under EU MiCA framework. The 1% base rate is higher than some alternatives but justified by the integrated features and compliance infrastructure.
Cryptomus
Cryptomus charges a 0.5% transaction fee with no monthly costs, matching NOWPayments on the headline rate. The platform supports a wide range of cryptocurrencies and provides standard e-commerce integrations including API access, website widgets, and plugins for popular CMS platforms.
Like NOWPayments, Cryptomus operates in a non-custodial manner, routing payments directly to merchant wallets. Withdrawals carry no platform fee. The 0.5% rate covers all transaction types without volume-based tiers, keeping things simple for budgeting purposes.
Cryptomus differentiates through its multi-wallet system and internal transfer capabilities, allowing merchants to organize funds across different operational wallets without triggering blockchain transactions. This reduces on-chain fees when moving money between business accounts.
The platform’s fee structure is transparent with minimal附加 costs. Currency conversion happens at the stated 0.5% rate with no separate spread charged on top. For merchants comparing per-transaction costs, Cryptomus sits alongside NOWPayments as one of the lower-priced managed options.
Which Option Delivers the Lowest Fees?
The answer depends on your operational capacity and transaction profile. If you can handle technical infrastructure, BTCPay Server is genuinely the cheapest option — zero platform fees make it unbeatable on pure cost. Lightning-enabled setups push effective fees close to zero per transaction.
Among managed platforms, NOWPayments and Cryptomus tie at 0.5%, making them equal choices on paper. The deciding factors become secondary: supported coin count, integration quality, UI experience, and specific features like fixed-rate checkout or multi-wallet organization.
CoinGate sits at 1% base, positioning it as the premium option for merchants willing to pay extra for fiat auto-conversion, regulated status, established e-commerce plugins, and dedicated support channels. High-volume Enterprise clients can negotiate below 1%, potentially reaching parity with the lower-cost platforms.
For most small to medium merchants without development resources, the choice between NOWPayments and Cryptomus comes down to feature preferences rather than cost. Both deliver the same headline rate with different secondary capabilities. Larger operations processing significant volume should request custom quotes from CoinGate and evaluate whether BTCPay Server’s self-hosted model fits their technical capacity.
