How much is your Stripe quietly leaking?
Most SaaS businesses lose a slice of revenue they never see — failed payments, expired cards, plan and price drift, dead webhooks, ghost customers. None of it shows up in your MRR. Move the two numbers below for a rough annual estimate, then run the audit to replace the estimate with your real figure.

Where the leak actually comes from
“Revenue leak” isn’t one thing. Driftcheck runs 10 deterministic detectors across the boundary between Stripe and your own database. The silent leaks it most often surfaces:
- Failed & uncollected payments — past-due and unpaid subscriptions Stripe still counts toward MRR but isn’t actually collecting.
- Expiring cards — charges that will quietly start failing this month or next.
- Plan & price drift — a customer on a price your app and Stripe no longer agree on.
- Dead webhooks — Stripe events your app silently failed to process, so your database and Stripe disagree.
- Ghost customers — someone paying in Stripe with no matching active account in your app, or the reverse.
- Expired coupons still applied — discounts that should have ended but keep reducing every invoice.
How the estimate works
The calculator applies a conservative industry range to the two numbers you enter, your monthly recurring revenue and a rough leak rate, to project an annual figure. It is intentionally a range, not a measurement: it cannot see your Stripe account, so it cannot know your real exposure. Think of it as a rough sense of scale. The only way to turn the estimate into a real number is to read your actual Stripe data, which is what the audit does.
Questions
How much revenue do SaaS companies lose to billing leaks?
It varies widely by business, but the floor is rarely zero. Failed payments alone are a large share: Stripe reports that roughly a quarter of subscription cancellations trace to payment failures rather than deliberate churn. On top of that sit quieter leaks (plan and price drift, ghost customers, expired coupons still applied) that never show up as a declined charge at all. This calculator models a conservative industry range; your real figure depends on your billing setup.
What causes Stripe revenue leakage?
It is rarely one thing. The common sources are failed and uncollected payments, cards expiring without an update, plan and price drift between your app and Stripe, webhooks your app accepted but silently failed to process, ghost customers paying with no matching account, and expired coupons that keep discounting every invoice. Driftcheck runs 10 deterministic detectors that each target one of these.
How accurate is this calculator?
It is an estimate, not a measurement. The model applies a conservative industry range to the two numbers you enter; it cannot see your actual Stripe data, so it cannot know your real exposure. Treat the result as an order-of-magnitude prompt, then run the audit to replace it with your true figure.
How do I find my actual Stripe revenue leak?
Run a Driftcheck audit with a read-only Stripe key. It reads your live account, runs the 10 detectors, and emails a ranked PDF of every leak it finds, each one traced to the exact Stripe object behind it. Read-only is enforced by Stripe, not by us, so the audit never writes to your account.
