Dunning ROI Calculator
Dunning software ROI is typically 500-2,000% for Stripe SaaS. At $15K MRR with 5% churn and 30% involuntary, dedicated dunning recovers ~$540/year more than Stripe retries alone; a 237% return on a $228/year tool cost. Payback period is usually under 1 month. The ROI scales linearly with MRR.
Is adding a dunning tool worth the cost? This calculator compares Stripe's built-in Smart Retries (35% recovery rate) against dedicated dunning software (55% average recovery rate) and shows you the exact ROI, net annual gain, and payback period. Plug in your numbers and see the math.

Where These Numbers Come From
The 35% recovery rate for Stripe Smart Retries is a conservative industry average based on aggregated Stripe data across SaaS accounts. Smart Retries uses machine learning to determine optimal retry timing, but without additional customer outreach through dunning emails, most failed payments go unrecovered. It is enabled by default for all Stripe accounts and represents your baseline payment recovery rate. See our failed payment recovery benchmarks for more detail.
The 55% recovery rate for dedicated dunning software is based on industry data from multiple dunning providers across thousands of SaaS companies in 2025 and 2026. Dedicated dunning tools layer email sequences, SMS reminders, in-app banners, and payment method update flows on top of Stripe's retry logic. The combination of smart retries plus multi-channel customer communication pushes recovery rates to 50-65% depending on the product and audience, with 55% being a conservative median.
The gap between 35% and 55% might look small, but on a meaningful MRR base it translates to thousands of dollars in annual recovered revenue. The calculator above shows the exact impact for your specific numbers.
When Dunning Pays for Itself
For most SaaS companies above $5,000 MRR, a dedicated dunning tool pays for itself within the first month. The math is straightforward: if your involuntary churn is even a few hundred dollars per month, the additional 20 percentage points of recovery (from 35% to 55%) almost always exceeds the $19-$49 monthly cost of a dunning tool.

At $15,000 MRR with 5% churn and 30% involuntary, the involuntary loss is $225/month. Stripe recovers roughly $79 of that. A dedicated dunning tool recovers roughly $124. That additional $45/month covers a $19 tool cost on day one, and the gap only grows as your MRR increases.
The ROI improves dramatically at higher MRR levels. At $50,000 MRR with the same churn profile, the additional recovery is $150/month, turning a $19 tool into a 9,400% annual ROI investment. There are very few expenses in a SaaS business that deliver that kind of return.
The only scenario where dunning does not pay for itself is when your MRR is very low (under $2,000) or your involuntary churn is already near zero. For everyone else, it is one of the clearest positive-ROI investments you can make.
