A merchant doing $1 million a month in crypto payments will pay roughly $120,000 in processor fees in 2026. On a flat-rate non-custodial alternative, the same merchant pays $5,988. The difference is $114,000 a year. Round to thirty thousand by the time you account for chargeback overhead, fiat off-ramp spread, and reconciliation engineering. That is the rough headline number. Here is the math.
Where the percentages come from
At $1M monthly volume, your processor cost is the sum of three things:
Transaction percentage. CoinGate charges a flat 1 percent. BitPay's tiered model is 1.5 percent at the $500K-$999K tier and 1 percent at $1M+. NOWPayments is 0.5 percent for same-coin payments and 1 percent for auto-convert. Stripe Crypto launched at 1.5 percent.
Per-transaction flat fee. BitPay tacks on $0.25 per invoice. NOWPayments adds 0.5 percent for auto-conversion. Most processors do not advertise the per-transaction fee until the invoice arrives.
Spread on the fiat conversion. When the processor converts crypto to fiat for you, the spread between the rate they quote you and the rate they actually execute at can be 30 to 100 basis points. On a $1 million volume that is $3,000 to $10,000 a year nobody calls a "fee" but you pay it anyway.
For a $1M/month BitPay merchant doing 5,000 transactions a month, the math is: - 1.5 percent × $1M = $15,000 - $0.25 × 5,000 = $1,250 - Conversion spread ~0.4 percent = $4,000 - Total: $20,250/month, $243,000/year
For the same merchant on NOWPayments at 1 percent auto-convert: - 1 percent × $1M = $10,000 - Per-transaction friction (none explicit) - Conversion spread ~0.3 percent = $3,000 - Total: $13,000/month, $156,000/year
The straight 1 percent crowd (CoinGate, BitPay enterprise tier, Coinbase Commerce) lands in the $120,000 to $156,000 range depending on conversion spread.
What a flat-rate model collapses to
Plaitr's pricing for a $1M monthly merchant is the Growth tier: $499/month. That is $5,988 a year. No per-transaction fee. No conversion spread (the merchant chooses the settlement asset and routing is done at best-rate). 100 percent keep rate.
The annual cost difference versus BitPay (1.5 percent tier): $243,000 - $5,988 = $237,012.
Versus NOWPayments (1 percent auto-convert): $156,000 - $5,988 = $150,012.
Versus the cheapest percentage processor ($120,000 floor): $120,000 - $5,988 = $114,012.
Even on the conservative comparison, the merchant saves over $100,000 a year. The $30,000 headline is a deliberate underestimate that holds even after accounting for ancillary costs the flat-rate model also eliminates (chargeback handling, account holds, fiat off-ramp spreads).
The compounding effect of fee removal
Saving $100,000+ a year is not just $100,000+ a year. It is a structural change in unit economics that compounds.
Cost of acquisition can rise. If your CAC payback period was 12 months at the prior fee structure, the freed margin makes a 14-month payback acceptable. You can outbid competitors on paid acquisition.
Pricing power expands. The merchant can drop prices 1 percent across the catalog (matching what the processor used to take) and absorb zero margin hit. Customers see lower prices. Competitors do not.
Hiring runway extends. $100K/year is roughly one senior engineer in a competitive market or two mid-level hires in lower-cost geographies. The hire that you could not justify before becomes affordable.
The runway extension itself is the deal. For a Series A startup with 18 months of runway, $100K/year of additional cash flow extends runway by roughly 2 months. That extension is the difference between hitting a milestone and not.
The objection: "we get other things for the 1 percent"
Three objections show up when merchants run this math.
"The processor handles fiat conversion for me." True for custodial processors. Plaitr handles fiat off-ramp in 100+ countries with same-day settlement, included in the subscription. The merchant chooses USDC, USDT, or fiat at the settlement step. The routing is best-rate. The spread is the on-chain DEX spread, not a processor-marked-up spread.
"The processor handles chargebacks." Crypto payments have no chargebacks. The chargeback feature for card-rail processors does not apply to crypto-rail processors. Any processor that lists "chargeback protection" as a feature on their crypto product is selling a feature that the rail does not need.
"The processor handles compliance and KYC." True if you want them to KYC your merchants on your behalf. False if your business does not need merchant-side KYC. Most non-custodial businesses do not because the rail never holds the funds.
The honest answer is that the 1 percent at scale is paying for brand recognition, support staff, and the legacy of running an enterprise sales motion. None of those things are linearly tied to your transaction volume. They are essentially fixed costs that the processor is amortizing across customers via a percentage rate.
Why processors will not voluntarily switch to flat fees
Percentage pricing maximizes processor revenue. A processor charging 1 percent of a $3M/month merchant collects $360,000 a year. A flat-fee processor charging $999/month for the same merchant collects $11,988. The flat-fee model collects 3 percent of what the percentage model collects.
No processor with a percentage model is going to switch voluntarily. The math is structurally unfavorable to them. The only way the industry moves to flat fees is when merchants start moving first, and the percentage processors lose enough volume that the model becomes untenable.
In 2026 that migration is still early. The merchants who run the math switch. The merchants who do not, do not. The annual cost of "not running the math" for a $1M/month operation is roughly $100,000.
The migration cost
A merchant currently on BitPay or Stripe Crypto thinking about switching to a flat-rate non-custodial rail should expect:
- •Engineering time: 1 to 3 days to swap the checkout integration. Plaitr's REST API is similar in shape to Stripe's. Webhook events map one-to-one.
- •Wallet operations: Set up a treasury wallet (Safe multisig recommended for businesses over $250K/month). Cost: a few hours of compliance and security review.
- •Settlement reconciliation: Update accounting software to expect on-chain confirmations as settlement events instead of processor payouts. Cost: half a day for QuickBooks or Xero, more for custom systems.
Net migration cost: roughly a week of engineering time for a typical merchant. Annual savings on $1M monthly volume: $100,000+. The payback period on the migration is roughly 18 hours of operations.
What to do this week
Run the numbers on your last 12 months of processor invoices. Sum the explicit fees, the per-transaction flats, and the conversion spreads. Divide by your gross volume to get an effective rate. Multiply by 12 to get an annual cost.
Compare to a flat-fee rail at your volume tier: $99/month under $100K, $499/month at $100K to $3M, $999/month above. The delta is the upside.
If the delta exceeds the salary of one of your engineers, the question is not whether to migrate. The question is when.
