Revenue Churn

Revenue churn counts dollars. Customer churn counts heads. They tell different stories. You might lose ten $10/month customers and barely notice, but lose one $500/month enterprise account and your month looks very different. Revenue churn (also called MRR churn) captures that distinction by measuring how much recurring revenue you lose each month as a percentage of your starting MRR.

Revenue churn formula

Revenue churn rate = Churned MRR / Starting MRR x 100

Say you started the month with $100,000 in MRR. Cancellations, downgrades, and failed payments cost you $5,000. Your revenue churn rate is 5%. That's the gross number, the total before any offsets.

For the net version, subtract expansion revenue: Net revenue churn rate = (Churned MRR - Expansion MRR) / Starting MRR x 100. If existing customers upgraded by $3,000 in the same period, your net revenue churn rate drops to 2%. For a deeper comparison, see gross churn vs net churn.

Gross vs net revenue churn

Gross revenue churn counts all lost revenue from cancellations, downgrades, and failed payments. No offsets, no credit for upsells. It's the raw picture of how leaky your bucket is.

Net revenue churn offsets those losses against expansion revenue from upgrades and add-ons. The best SaaS companies achieve negative net revenue churn, where expansion outpaces losses. Their existing customer base grows in value even without new sign-ups. That's the goal.

Why revenue churn matters more than logo churn

Logo churn treats every customer equally. Revenue churn doesn't. In practice, this makes revenue churn a much more honest indicator of business health, especially if you have a wide range of plan sizes.

One thing to flag: 20 to 40% of revenue churn typically comes from failed payments rather than deliberate cancellations. Recovering this involuntary revenue churn through dunning directly improves both your gross and net numbers.
