Failed Payment Recovery Calculator

A failed payment recovery calculator puts a dollar figure on involuntary churn, the customers who did not cancel but whose card was declined, expired, or otherwise failed to process. Enter how many payments fail each month, your average subscription value, and the recovery rate you see with and without an active dunning campaign, retry logic, and reminder emails that chase down failed charges.

Involuntary churn is a solvable problem

Unlike voluntary cancellations, a failed payment usually does not mean the customer wants to leave. Expired cards, insufficient funds on a given day, or a bank's fraud filter can all cause a decline that has nothing to do with satisfaction. A structured dunning process, automatic retries on a schedule plus clear email reminders, recovers a meaningful share of that revenue without any change to the product or pricing.

How the calculation works

The tool multiplies your failed payment count by average subscription value to find total revenue at risk each month. It then applies your baseline recovery rate, what happens with no dunning effort, and your dunning recovery rate, what you achieve with retries and reminders, to the same at-risk revenue. The difference between the two is the incremental revenue your dunning process is actually responsible for.

Where to get your recovery rate inputs

Most billing platforms, including Stripe, Chargebee and Recurly, report recovery rate for failed payments directly in their dashboards, often split by whether a dunning campaign was active. If you do not have a clean baseline, run your dunning process off for a short test period on a small segment to establish one, then compare it against your normal recovery rate.
