What is a good net MRR churn rate? 

To grow a SaaS business, it’s ideal to have a negative net MRR churn rate, as this means you’re gaining more through expansion and reactivation than losing through contraction and cancellations. Growing your revenue from existing customers typically means you’ll spend less compared to the cost of acquiring brand new subscribers.

ChartMogul calculates Net MRR Churn Rate based on your Churn Rate Formula setting.

Standard Formula (B2B)


Math equation: open paren sum of Churn and Contraction MRR minus sum of Expansion and Reactivation MRR close paren divided by MRR as the start of the period


At the start of the month, you have $100 in MRR. During the month, you lose $10 to churn and $10 to contraction, while one customer increases their MRR by $10. Your net MRR churn rate is 10%: (($10 + $10) − ($10 + $0)) ÷ $100.

Shopify Formula (B2C)


Math equation: sum of 1 minus open paren open paren MRR at the end of the day minus New Business MRR that day close paren divided by MRR at the start of the day close paren


You have $100 in MRR at the start of the day and $120 in MRR at the end of the day. $10 of the growth in MRR came from new business. Your net MRR churn rate is −10%: 1 − ((120 − 10) ÷ 100)).
