Stripe failed-payment recovery calculator for indie SaaS founders
Estimate how much MRR is leaking through involuntary churn, what a realistic recovery experiment could bring back, and what monthly payback threshold a recovery tool needs to clear.
No production DB writes, no Stripe pricing changes, and no outbound email. The first pass is manual and transparent.

ChurnWin is validating a sharper failed-payment recovery ICP before broad feature expansion. Failed payments are often an under-measured part of subscription churn; for small SaaS founders, the first question is whether the leak is large enough to justify extra workflow.
Your current Stripe subscription MRR.
If you know monthly churn MRR, multiply it by the share caused by failed payments. Involuntary churn is often an under-measured slice of subscription churn, so start with a conservative leak rate and adjust.
Use an assumption, not a guarantee. Lower it until the payback case still looks rational.
Compare against your expected ChurnWin or dunning-tool budget. This does not change ChurnWin pricing.

Formula transparency
- Revenue at risk = MRR × failed-payment leakage %.
- Recoverable revenue = revenue at risk × expected recovery %.
- Payback threshold = (monthly tool cost ÷ revenue at risk) × 100%.
These are manual assumptions. Once Stripe is connected, ChurnWin reports your measured recovered payments and recovered MRR from real successes after failures — starting at zero, never an estimate.
- Confirm Stripe Smart Retries, customer emails, and payment method update flows are enabled before layering on another tool.
- Measure failed-payment MRR separately from voluntary cancellations so the leak is not hidden inside blended churn.
- Prioritize card update, retry timing, and customer-facing payment links before adding complex retention automation.
- You are a bootstrapped Stripe SaaS around $5k–$50k MRR and want a fast, founder-readable leak report.
- You need to decide whether a lightweight recovery workflow can pay back before buying a larger dunning or analytics suite.
- You want failed-payment recovery context next to churn analytics, cancellation feedback, and retention prioritization.
- Enterprise dunning platforms can make sense when payment volume is high, teams are larger, or recovery playbooks need deep customization.
- Analytics add-ons can be useful when you already want broad subscription reporting, but they may not be the cheapest first step for a narrow failed-payment leak.
- This calculator keeps the first decision simple: is the at-risk revenue large enough to justify the next recovery experiment?
The calculator above is a manual estimate. Once you connect Stripe, ChurnWin replaces those assumptions with attributed recoveries from your real billing data.
- A recovery is a payment that succeeds within about 30 days of a recent failure for the same customer — the Stripe Smart Retries window — and ChurnWin is designed to credit each failure to a single recovery.
- Recovered count and recovered MRR are derived from your real Stripe data, so they read a truthful zero until a genuine recovery happens instead of a fabricated benchmark.
- Live attribution needs Stripe to send payment events to your ChurnWin account; until that connection is set up, the dashboard shows zero rather than guessing.
Frequently asked questions
No. It is a manual estimator so founders can size the opportunity safely before connecting live billing data.
No. The recovery-rate field is an assumption you control. The calculator shows the math and the break-even threshold, not a guaranteed outcome.
Conservatively. ChurnWin attributes a recovery only when a payment succeeds within about 30 days after a recent failure for the same customer, mirroring Stripe Smart Retries, and is designed to credit each failure to a single recovery. Counts come from your real Stripe data and stay at zero until a genuine recovery is matched.
Yes. Start with Stripe Smart Retries, customer emails, payment method updates, and recovery reporting, then use ChurnWin to decide whether extra workflow is worth doing.
Turn the estimate into a recovery checklist
If the math clears your payback threshold, the next step is a focused ChurnWin account: connect Stripe, separate voluntary churn from failed-payment churn, and decide which recovery actions are worth doing first.
