How to Calculate Net MRR Churn
Formula
Net MRR Churn = Churned MRR + Contraction MRR - Expansion MRR Net MRR Churn Rate = Net MRR Churn / Starting MRR x 100
Net MRR churn is the ultimate SaaS retention metric because it captures both the revenue you lose and the revenue you grow from existing customers in a single number. When expansion exceeds losses, you achieve net negative churn, meaning your existing customer base generates more revenue over time even without new sales. This is the most powerful growth engine a SaaS company can build.
Example Calculation
Starting MRR is $200,000. Cancellations lost $10,000, downgrades lost $3,000, but expansions added $15,000.
- 01Net MRR Churn = $10,000 + $3,000 - $15,000 = -$2,000
- 02Net MRR Churn Rate = (-$2,000 / $200,000) x 100 = -1%
- 03Negative churn of -1% means existing customers grew by $2,000 net.
