Where do these numbers come from?
The default rates assume a healthy mid-market SaaS:
- • Voluntary churn (active cancellations): typically 3-5% monthly
- • Involuntary churn (failed payments): typically 1-2% monthly
- • Recovery rate for failed payments with smart dunning: 40-60%
- • Save rate for cancel flows with conditional offers: 25-40%
We use conservative midpoints (50% recovery, 30% save) so the projection underpromises. Your actual numbers depend on your audience and pricing.
Why does this matter so much?
Churn compounds. Every customer you lose costs you not just this month's MRR but the entire LTV they would have generated. A 30% save rate over a 24-month customer lifetime translates to 7-9× the displayed monthly savings.
