SaaS ROI Calculator

The ROI formula: (Revenue Recovered - Tool Cost) / Tool Cost × 100. If a dunning tool recovers $360/month at $29/month, the ROI is 1,141%. Expressed as a multiple, that's 12.4x your investment back each month.

What dunning tools recover: Involuntary churn from failed payments accounts for 20-40% of total churn. Dedicated dunning tools can recover a significant share of those failures. The exact rate depends on the failure reasons in your subscriber base and how quickly retries and notifications are triggered.

The average payback period is under one month. Most teams see positive ROI within the first week.

Retention vs. acquisition: Every $1 spent on retention is worth $5-7 compared to acquiring a new customer. Failed payment recovery is the highest-ROI form of retention because these customers already want to stay. They haven't churned voluntarily. They've just hit a billing problem that needs fixing.

Here's the thing: most SaaS teams focus their retention budgets on product improvements and customer success. Those matter, but they don't address the 20-40% of churn that's purely involuntary. Fixing payment failures is the lowest-effort, highest-return retention investment you can make.

You can also use our revenue loss calculator to see how much failed payments are costing you before recovery.

It depends on the category, but for revenue recovery tools the bar is low because the alternative is doing nothing and losing the revenue entirely. Any positive ROI means the tool pays for itself.

In practice, dunning tools routinely deliver 10x-50x returns. The maths is straightforward: a flat $29/month fee against hundreds or thousands in recovered revenue. As your MRR grows, the ROI only increases because the tool cost stays fixed while the recoverable amount scales with your subscriber base.

Benchmark by MRR: At $5,000 MRR with a 9% failure rate and 40% recovery, you'd recover $180/month for $29, a 6.2x return. At $50,000 MRR with the same rates, that jumps to $1,800/month, a 62x return. The inflection point where dunning becomes obviously worth it is surprisingly low.
