Why Retention Matters
Even a 1% improvement in retention creates massive leverage. Reducing churn from 5% to 4% increases your Max MRR by $2,500.
Retention Benchmarks
2-3% = Excellent (sustainable growth)
4-5% = Good (room for improvement)← You're here!
6-7% = Risky (growth will stall)
8%+ = Critical (fix retention first)
Quick Tips
•If your max is too low, reduce churn before adding more customers
•Growth rate matters less than retention at scale
•Hitting your ceiling means growth stalls despite new customers
