What the result means
Healthy SaaS profit depends on churn control, margin discipline, and efficient growth. Rule of 40 combines growth and profit margin.
Net revenue = MRR × (1 − churn). Profit = net revenue − costs. Rule of 40 = growth rate + profit margin.
A company can grow fast but still have weak economics if churn and costs are too high.
Example calculation
With $50,000 MRR, 4% churn, $35,000 costs, and 20% growth, net revenue is $48,000 and profit is $13,000.
Tips for better results
- Reduce churn before scaling spend.
- Improve gross margin through hosting efficiency.
- Track Rule of 40 monthly.
