Stripe Dunning Recovery ROI Calculator
Free failed payment recovery calculator for bootstrapped founders. Model how much MRR you recover from Stripe retries and dunning emails versus involuntary churn — and whether a paid dunning tool pays for itself.
What is dunning recovery ROI?
Not all churn is a breakup. A large share of subscription losses on young Stripe billing is involuntary — expired cards, insufficient funds, bank holds. Dunning recovery is the stack that brings those invoices back: retries at smarter times, a past_due grace window, and emails with one tap to update payment.
This stripe dunning recovery calculator turns your failed-payment volume into dollars: how much MRR is at risk each month, how much you recover with your stack, and how much slips away as involuntary churn. Solo founders who only track canceled subscriptions miss the cheaper win sitting in past_due invoices.
How to use this calculator
Enter failed payment invoices per month and your average subscription price. Set your recovery rate with your current dunning stack — Smart Retries, portal links, and emails — and a baseline rate without deliberate recovery to see the lift.
Optionally add a monthly dunning tool cost to estimate ROI on paid recovery software. The results show recovered MRR, lost MRR, additional revenue versus baseline, and annual projections.
Copy the link to save a scenario. For the full recovery stack — retry settings, email cadence, and when not to buy third-party tools — see the related reading below.
Why solo founders need recovery math
Eight failed invoices at $39 each is $312 of MRR at risk in one month. Recovering two instead of six because retries are off is not a product problem — it is operator discipline. Seeing that gap in dollars is often enough to spend an afternoon on portal links instead of another feature nobody requested.
Split voluntary churn from involuntary losses before you rewrite pricing or onboarding. A churn impact calculator shows what cancel rate costs you; this calculator shows what failed payments cost when you do not recover them. Fix the cheaper ledger first.
Frequently asked questions
What is failed payment recovery for SaaS?
Failed payment recovery is the process of turning declined subscription charges back into paid invoices — through Stripe Smart Retries, Customer Portal update links, and short dunning emails. It targets involuntary churn: customers who still want your product but had a card glitch, not customers who clicked cancel.
How do I calculate dunning recovery ROI?
Multiply failed invoices per month by your average subscription price to get MRR at risk. Apply your recovery rate to see recovered MRR versus lost MRR. Compare your rate with a dunning stack against a baseline without one to estimate how much extra revenue your retries and emails save each month.
What is a good failed payment recovery rate?
With Smart Retries, Customer Portal links, and a short email cadence, many micro-SaaS founders recover 50–80% of failed invoices. Without deliberate dunning — retries off, vague emails, instant lockouts — recovery often sits in the 20–30% range. Track your own rate monthly instead of copying industry averages.
When should I buy a third-party dunning tool?
After Stripe Smart Retries, Card Account Updater, Customer Portal, and a three-email cadence are live and you have measured recovery for a few months. Enter your tool cost in this calculator to see whether the extra recovered MRR beats the annual spend. At a few thousand dollars MRR, native Stripe dunning is usually enough.
