Max MRR: Your Growth Ceiling — Jason Cohen

Max MRR: Your Growth Ceiling

Author: Jason Cohen (founder, WP Engine) URL: https://longform.asmartbear.com/max-mrr/

Summary

The simplest and most important SaaS formula: Max MRR = New MRR ÷ Monthly Churn Rate. At 5% monthly churn adding $1K/mo new MRR, you’ll never exceed $20K MRR — regardless of market size. Reducing churn from 7% to 4% increases your ceiling by 75%. This predicts revenue plateaus months before they occur and proves that churn reduction often matters more than acquisition growth.

Key Claims

1. Max MRR = New MRR ÷ Monthly Churn Rate (the formula)

3. Reducing churn from 7% → 4% increases ceiling by ~75%
4. Churn reduction compounds more powerfully than acquisition growth
5. The formula predicts plateaus months before they happen
6. Two levers: increase new MRR or decrease churn rate
