How to Use This Calculator
- Enter Starting MRR, Contraction MRR, and Churned MRR.
- GRR %, retained MRR, and benchmark status appear instantly.
- Use Voluntary vs Involuntary tab to split churn types.
- Use Compare to NRR to see the expansion lift gap.
- Switch to Professional for annual loss projection and dunning opportunity estimate.
Formula
GRR = (Start MRR − Contraction − Churn) / Start MRR × 100 (capped at 100%)
Example
Start MRR: $100K, Contraction: $5K, Churn: $8K → Retained = $87K → GRR = 87%.
Frequently Asked Questions
- GRR measures how much recurring revenue is retained from an existing customer cohort, excluding any expansion revenue. GRR = (Start MRR − Contraction − Churn) / Start MRR × 100. It is always capped at 100%.
- Best-in-class is >95%. Healthy is 90–95%. Below 85% is at-risk. Enterprise SaaS typically achieves higher GRR (95–98%) than SMB-focused SaaS (85–92%) due to higher switching costs.
- GRR excludes expansion MRR and is capped at 100% — it purely measures your ability to retain existing revenue. NRR includes expansion and can exceed 100%. GRR is a purer measure of customer satisfaction and product stickiness.
- Involuntary churn happens when customers do not intend to cancel but lose access due to payment failures (expired cards, insufficient funds). Typically 20–40% of total churn. Dunning campaigns (automated retry + emails) can recover 20–50% of these.
- Focus on reducing voluntary churn (improve onboarding, engagement, NPS) and involuntary churn (implement dunning, update card reminders, offer annual plans). Segment analysis helps identify which plan tiers churn most.
