The Metric That Decides Whether Growth Compounds
Churn is the leak in the bucket; every point of it is growth you have to re-earn before you grow at all. A business losing 20 percent of its revenue base each year has to win that much in new business just to stand still. That is why churn, not new logos, is often the real constraint on durable growth. The number only means something when you specify which churn you are measuring.The Two Formulas
Logo churn rate = customers lost in period / customers at start of period x 100 Revenue churn rate = recurring revenue lost in period / recurring revenue at start of period x 100These can diverge sharply. Lose ten small accounts and keep every enterprise one, and logo churn looks alarming while revenue churn barely moves. Lose a single major account and the opposite happens. Reporting only one hides half the story.
Churn Rate Types at a Glance
| Type | What it counts | Can it go negative? |
|---|---|---|
| Logo churn | Customers lost | No |
| Gross revenue churn | Recurring revenue lost | No |
| Net revenue churn | Revenue lost minus expansion | Yes, when expansion wins |
Why Churn Is a Forecasting Input, Not Just a CS Metric
Churn is usually owned by customer success, but it belongs in the revenue model. Your renewal base is part of next quarter's number, and a churn assumption that is too optimistic inflates the forecast exactly the way an inflated new-business pipeline does. The cleaner way to express the same dynamic on the upside is retention: gross revenue retention is the mirror of gross churn, and net revenue retention folds expansion back in. Track churn by cohort, segment, and contract length, because a blended rate averages away the pattern you need to act on.

Frequently Asked Questions
What is the churn rate formula?
Logo churn rate equals customers lost in a period divided by customers at the start of the period, times 100. Revenue churn rate equals recurring revenue lost divided by recurring revenue at the start, times 100. Always state which one you mean, because they can tell opposite stories.
What is the difference between logo churn and revenue churn?
Logo churn counts how many customers left; revenue churn counts how many dollars left. If you lose ten small accounts but keep every large one, logo churn looks high while revenue churn stays low. If you lose one major account, the reverse happens. Tracking both prevents a comfortable number from hiding a real problem.
What is gross vs net revenue churn?
Gross revenue churn counts only lost revenue and can never be negative. Net revenue churn subtracts expansion from existing customers, so it can go negative when expansion outpaces losses. Negative net churn is the signal of a compounding business.
