Measure SaaS customer churn and revenue churn from lost customers and churned MRR. The calculator shows churn risk, retention impact, and practical recommendations for reducing revenue leakage.
The result shows whether customer and revenue losses are small enough for healthy SaaS compounding. Revenue churn is especially important because high-value customer loss can damage ARR faster than logo churn suggests.
Track logo churn, revenue churn, downgrade revenue, expansion revenue, NRR, and GRR separately for a complete retention picture.
If 35 of 1,000 customers leave, customer churn is 3.5%. If $2,500 of $50,000 MRR churns, revenue churn is 5%.
A good churn rate depends on segment and contract size, but lower monthly churn is generally required for strong SaaS compounding and fundraising quality.
Improve onboarding, customer success, product adoption, activation milestones, cancellation saves, and expansion fit rather than relying on discounts.
Revenue churn is higher when larger accounts cancel or downgrade. This means the company is losing more revenue than the customer count alone suggests.
Investors usually expect churn to decline as product-market fit improves and may compare churn against customer segment, ACV, and growth stage.
High churn reduces ARR durability, weakens NRR, increases CAC pressure, and can lower valuation multiples even when new sales are growing.
