How Much Does Stripe Billing Actually Cost at $500K MRR?

April 3, 2026  ·  7 min read

At $500K MRR, your billing platform alone costs you $42,000 a year. Most founders don't realize it until they run the math. Here it is.

Billing fees are one of those costs that rarely gets a line item in a board deck. They're small percentages — easy to ignore when you're at $10K MRR, but very real by the time you're scaling. At $500K MRR, the math stops being abstract.

This article breaks down exactly what Stripe Billing charges, what that looks like at every stage of growth, and what your options are when those fees start to matter.

How Stripe Billing pricing works

Stripe's core payment processing fee — 2.9% + 30¢ per transaction — is separate from Stripe Billing, which handles the subscription logic on top: recurring charges, proration, trials, dunning, customer portals, and revenue recognition. Stripe Billing charges an additional 0.70% of your monthly billing volume.

That 0.70% applies to everything you bill through the platform. Every renewal, every upgrade, every new subscriber. It's a percentage of revenue, not a flat fee — so it scales directly with your MRR.

Important distinction: The 0.70% Stripe Billing fee is charged on top of payment processing. If you're running $500K MRR through Stripe, you're paying both — the Billing fee and the per-transaction processing fee. This article focuses on the Billing fee specifically.

The math at every stage of growth

Here's what the 0.70% fee looks like from early-stage to scale — annually, so the number is harder to ignore:

At $500K MRR — the number we're modeling here — you're paying $3,500 every single month just for the billing layer. That's $42,000 a year, or $126,000 over three years assuming flat revenue. In reality, if you're growing, the number is higher.

What $42,000 a year actually buys

Putting a number in context always helps. $42,000 in annual billing fees is roughly:

Full-time hire

~0.5×

A junior engineer in most markets

Paid acquisition

$3,500

Per month in ad budget

Runway

~5 weeks

At typical early-stage burn

None of that is catastrophic on its own. But it's a real line item — and unlike most SaaS costs, it doesn't decrease as you grow. It increases proportionally with revenue, which means the compounding effect cuts both ways.

The compounding effect over three years

Billing fees don't stay flat. If you're growing — which is the whole point — the annual cost grows with you. A business going from $200K to $500K MRR over 36 months might pay $80,000–$100,000 in Stripe Billing fees over that period. Most of that goes untracked because it's deducted automatically and never shows up as a discrete expense.

The point isn't that Stripe Billing is a bad product — it's a capable platform with a well-built ecosystem. The point is that billing fees are a scaling cost, and like any scaling cost, it's worth knowing what you're paying and whether there are alternatives at a lower rate.

Is there a cheaper alternative?

Yes. Subscription billing platforms built on open-source infrastructure can offer meaningfully lower rates because their underlying cost structure is different. ChaChing, for example, charges 0.35% — half of Stripe Billing's 0.70% — with the same core capabilities: recurring billing, proration, dunning, customer portals, and usage-based models.

At $500K MRR, that difference is $1,750 per month — $21,000 per year, or $63,000 over three years.

Who this matters most to

At $10K MRR, the difference between 0.35% and 0.70% is $35 a month. It's not worth optimizing for. But the math changes fast. By $100K MRR you're looking at $4,200 a year in savings — at $500K MRR, it's $21,000. If you're between those two numbers and growing, the calculus is straightforward.

This is most relevant for B2B SaaS companies with predictable subscription revenue, a growing customer base, and a finance team (or founder) who's starting to scrutinize the cost structure. It's less relevant for usage-heavy products with erratic billing volume, or teams that are deeply embedded in the Stripe ecosystem and absorb the cost as a switching deterrent.

The bottom line

Billing fees are invisible until they're not. At $500K MRR, Stripe Billing costs $42,000 a year — a number that almost never appears in a budget conversation but compounds every month you stay at that rate. Whether you stay or switch, running the math is worth five minutes of your time.

If you're at or approaching $100K MRR and looking for a billing platform that costs half as much, ChaChing is built for exactly that.
