Net MRR Churn Rate

What is it?

Net Revenue Retention (NRR) Rate, also known as Net Dollar Retention (NDR), is the percentage of recurring revenue retained from existing customers in a defined time period, including expansion revenue, downgrades, and cancels. This churn metric gives a comprehensive view of positive as well as negative changes with respect to customer retention. A good NDR can range between 90% to 125%, based on target customer size.

Net Monthly Recurring Revenue (MRR) Churn Rate is the percentage change in MRR due to expansions, cancellations and downgrades. A negative Net MRR Churn Rate occurs when expansions exceed downgrades and cancellations and is a strong positive indicator of company health. This metric is typically expressed as a monthly rate although it can also be an annual rate: Net Annual Recurring Revenue (ARR) Churn Rate.


ƒ Sum(RR (recurring revenue) at the beginning of the period + expansion RR during the period - downgraded RR during the period - cancelled RR during the period) / (RR at the beginning of the period) Sum(renewing customers RR) / Sum(RR of customers due to renew)
ƒ Sum(downgraded MRR + cancelled MRR - expanded MRR) / (total MRR at the beginning of the month)


Here's an example of how to calculate Net Revenue Retention (NRR). We'll call this scenario A: A company has 100 customers, each paying $2,000 per month. MRR at the beginning of the month is $200,000. Within the month, 1 customer adds a $4,000 MRR upgrade, 2 downgrade by $500 each, and 1 customer cancels. Based on the Net Dollar Retention formula, NRR = ($200,000 + $4,000 - ($500 x 2) - $2,000) / $200,000 = $201,000 / $200,000 = 100.5% expressed monthly Now let's look at Scenario B: Another company has 100 customers paying $20,000 for annual subscriptions. Within a one month period, 10 customers are due for renewal, only 9 actually renew, 1 adds a $5000 ARR upgrade, and 2 downgrade their subscription by $2000 each. Net Dollar Retention = ($20,000 x 9) + $5,000 - ($2,000 x 2)) / ($2,000 MRR x 10) = $19,000 / $20,000 = 95.0% expressed monthly

Example A: A company’s MRR is $50,000 with expansions of $7,000 and downgrades and cancellations of $10,000. The Net MRR Churn Rate is ($10,000 - $7,000) / $50,000 = 6.0% Example B: A company’s MRR is $100,000 with expansions of $12,000 and downgrades and cancellations of $7,000. The Net MRR Churn Rate is ($12,000 - $7,000) / $100,000 = -5.0%
