Crypto Billing Costs at $1k, $10k, and $100k MRR: A Real-World Breakdown

Running a subscription business means you're constantly fighting the 'MRR tax'-the percentage of your revenue that vanishes into payment processing fees. If you're on traditional card networks like Stripe or PayPal, you're likely paying between 2.9% and 3.4% plus a fixed fee per transaction. That's a steep price to pay for convenience.

Crypto billing promises lower fees, instant settlement, and zero chargebacks. But does it actually save you money at different stages of growth? The answer isn't as simple as "yes." It depends entirely on which gateway you choose, how big your average invoice is, and whether you settle in fiat or keep your funds on-chain.

Let's break down exactly what you'll pay at three critical milestones: $1,000, $10,000, and $100,000 in monthly recurring revenue (MRR). We'll look at the math behind popular processors like BitPay, Coinbase Commerce, OpenNode, and self-hosted options like BTCPay Server.

The Hidden Variable: Average Ticket Size

Before we dive into the specific gateways, there's one variable that changes everything: your average subscription price. Why? Because some crypto processors charge a flat percentage, while others add a fixed fee per transaction.

If you have a small SaaS with a $5/month plan, a $0.25 fixed fee eats up 5% of that transaction instantly. If you have an enterprise tool charging $500/month, that same $0.25 fee is negligible. For this analysis, I'm using a standard $50/month subscription as our baseline. This gives us:

• $1,000 MRR: 20 active subscribers
• $10,000 MRR: 200 active subscribers
• $100,000 MRR: 2,000 active subscribers

This scenario helps us see how fixed fees impact smaller businesses versus larger ones.

BitPay: The Volume-Tiered Model

BitPay is one of the oldest and most established crypto payment processors, known for its tiered pricing structure based on monthly volume. BitPay doesn't offer a single flat rate for everyone. Instead, they scale their fees as you process more money. However, until you hit massive volumes, you're stuck in the highest fee bracket.

As of early 2026, merchants processing under $500,000 per month fall into the base tier. Here’s the deal: 2% of the transaction value + $0.25 per invoice.

Let's run the numbers for our $50 subscription:

Notice something interesting? The effective rate stays at 2.5% regardless of your MRR, because the fee scales linearly with the number of transactions. You only start saving if your total volume crosses $500,000/month, dropping the percentage to 1.5%. For most growing SaaS companies, BitPay feels expensive compared to newer competitors.

Coinbase Commerce & OpenNode: The Flat 1% Standard

Coinbase Commerce is a merchant solution from Coinbase that historically charged a 1% transaction fee on crypto payments, though recent updates suggest potential shifts toward 0% processing fees with optional conversion costs. Meanwhile, OpenNode is a Bitcoin-focused payment processor that charges a flat 1% fee with no setup or monthly costs.

These two platforms represent the "standard" for managed crypto gateways. They are easy to integrate, require minimal technical knowledge, and handle the complexity of blockchain interactions for you. Both typically charge a flat 1% fee on the transaction value.

Here is how those costs stack up against our baseline:

• At $1,000 MRR: You pay $10/month. That's 1% of your revenue.
• At $10,000 MRR: You pay $100/month. Still just 1%.
• At $100,000 MRR: You pay $1,000/month. Consistent 1% cost.

This is significantly cheaper than BitPay's 2.5% effective rate. Compared to Stripe's ~2.9%, you're saving roughly 1.9% of your revenue. At $100k MRR, that's nearly $1,900 saved every month. Plus, unlike credit cards, these transactions cannot be reversed by a customer changing their mind.

Note on Coinbase Commerce: Some recent industry reports suggest Coinbase may be shifting its model, potentially offering 0% processing fees but charging for instant fiat conversion. If this holds true, the cost drops to near-zero for merchants willing to hold crypto, making it incredibly competitive. Always verify current terms before integrating.

BTCPay Server: The Self-Hosted Zero-Fee Option

BTCPay Server is an open-source, self-hosted Bitcoin payment gateway that charges 0% processing fees, requiring merchants to host the software themselves. This is the gold standard for sovereignty. There is no middleman taking a cut. No platform fees. Ever.

So, why isn't everyone using it? Because "free" has a hidden cost: infrastructure. You need to host the server yourself. You can rent a Virtual Private Server (VPS) from providers like LunaNode or use managed hosting like Elestio.

A typical setup might cost around $16 to $18 per month for a VPS instance capable of running a full node or light client. Let's use $16/month as our fixed infrastructure cost.

Look at that drop. At $1,000 MRR, BTCPay is slightly more expensive than Coinbase Commerce (1.6% vs 1%) because the fixed hosting cost weighs heavily on low volume. But once you cross $10,000 MRR, BTCPay becomes dramatically cheaper. At $100k MRR, you're paying fractions of a percent. This makes self-hosting ideal for high-volume operations or developers who want maximum control over their data and funds.

Strike & Fiat Settlement: The Spread Trap

Strike is a Bitcoin Lightning wallet and business payment solution that advertises ultra-low fees, often charging no explicit transaction fees but applying a spread when converting to fiat. Strike is popular because it integrates well with platforms like Shopify and offers a smooth user experience. They claim "no added transaction fees" for sending and receiving Bitcoin.

However, if you don't want to hold volatile Bitcoin, you'll convert it to USD or EUR immediately. Strike applies a spread of approximately 1% on these conversions. In practice, this functions exactly like a 1% processing fee.

If you settle in fiat via Strike:

• $1,000 MRR: ~$10 cost (1% spread)
• $10,000 MRR: ~$100 cost (1% spread)
• $100,000 MRR: ~$1,000 cost (1% spread)

The key difference here is transparency. With Coinbase or OpenNode, the 1% is clearly labeled as a "processing fee." With Strike, it's hidden in the exchange rate. If you're comfortable holding Bitcoin, Strike can be even cheaper, costing only the minimal network routing fees (often less than a penny per transaction).

The Emerging Contender: TxNod

There's a new player gaining traction among solo founders and indie hackers: TxNod is a non-custodial multi-chain crypto payment gateway that uses a flat subscription model rather than a percentage take-rate. Unlike BitPay or Coinbase, TxNod doesn't take a cut of your sales. Instead, it operates on a flat $20/month subscription per operator, with a 0% take-rate on payment volume.

This model flips the script on traditional economics. Let's see how it compares:

At $1,000 MRR, TxNod is slightly more expensive than the 1% gateways ($20 vs $10). But as soon as you pass $2,000 MRR, it becomes cheaper than any percentage-based model. At $100k MRR, you're saving thousands compared to BitPay or even Coinbase. Plus, since it's non-custodial, funds go straight to your hardware wallet (Ledger or Trezor), eliminating counterparty risk entirely. No account freezes, no payout holds.

Which Gateway Should You Choose?

Your choice depends on your technical comfort level, volume, and custody preferences.

1. For Beginners / Low Tech Skill: Stick with Coinbase Commerce or OpenNode. The 1% fee is fair, integration is plug-and-play, and support is readily available. It's the easiest way to start accepting crypto without worrying about servers or keys.
2. For High Volume / Technical Teams: Go with BTCPay Server. The upfront effort of setting up a VPS pays off massively as you scale. You get 0% fees and total sovereignty. Ideal if you have a developer on staff.
3. For Solo Founders / Indie Hackers: Consider TxNod. The flat $20/month fee is predictable and scales beautifully. You get non-custodial security (your own Ledger/Trezor) without the headache of managing a server. It's designed specifically for builders who want to ship fast and keep their margins.
4. For Shopify Merchants: Strike offers a seamless integration. Just remember that converting to fiat will cost you roughly 1% in spreads.

Remember, the goal isn't just to lower fees-it's to reduce friction for your customers and protect your revenue from chargebacks. Crypto billing delivers on both fronts, provided you pick the right tool for your stage of growth.
