What Is Churn Rate?
The Subscription Metric Every Team Should Track First
How to Calculate Churn Rate
The formula is (Customers Lost ÷ Customers at Start of Period) × 100. Begin January with 1,000 subscribers and lose 50, and monthly churn is 50 ÷ 1,000 × 100 = 5%. Customers who both joined and left inside the same period are usually excluded, so that the denominator stays a fixed group.
Annualizing is not multiplication, and that trips people up fairly regularly. Annual churn is 1 − (1 − monthly rate)^12, so 5% a month compounds to roughly 46% over a year rather than 60%, because every month's loss applies to a base the month before already reduced. The same arithmetic works in your favor: small monthly improvements accumulate into large annual ones.
What's a Good Churn Rate?
Industry benchmarks are worth having for orientation, but they're easy to misread, and the measurement period usually matters more than the industry does. Stripe puts SaaS at 38% churn, which reads as a catastrophe until you notice it's annual, measured on monthly-billed subscriptions only, and works out near 3.9% a month (Stripe Churn Benchmarks, 2025).
On that same annual basis, the spread across industries is narrower than most people expect: travel and lodging 43%, business services and education 40%, merchandise 39%, insurance 37%, leisure 36%, furniture 28% (Stripe Churn Benchmarks, 2025). Measured monthly instead, the top quartile of SaaS companies runs 1-2% per month (ChartMogul SaaS Benchmarks, 2023). Before comparing yourself to any benchmark, check whether it's monthly or annual and whether it counts customers or revenue.
Types of Churn Rate
Customer churn counts subscribers and revenue churn counts money. The two diverge as soon as your customers aren't all worth the same, since losing ten small accounts and losing one large one can produce identical customer churn and very different revenue churn. Reporting both side by side is the only way to see which kind of loss you're actually taking.
Churn also splits by cause. Voluntary churn is a subscriber deciding to leave, while involuntary churn is a payment failing. Blending the two is fine for a board slide, but it hides which of them you should be spending on.
Why Churn Rate Matters
Churn sets the ceiling on your growth. A business losing 5% of its customers per month has to replace roughly 46% of its base over a year before it grows at all, and it pays that replacement cost again every year rather than once.
It also determines how long a customer relationship lasts. At a steady 5% monthly churn the average subscriber stays 20 months (1 ÷ 0.05), and at 3% about 33. That gap feeds straight into lifetime value and into how much you can afford to spend acquiring a customer, which is why churn is usually worth improving before you scale acquisition spend.
How to Reduce Churn Rate
Separate the two causes first, because the fixes have nothing in common. Failed payments are an infrastructure problem, handled in your payment processor and your dunning setup. Deliberate cancellations are a product and value problem.
For voluntary churn, most of the work happens long before the cancel page: setting expectations accurately at the point of sale, getting new customers to the thing they bought quickly, and continuing to deliver after the novelty wears off. Falling usage is the warning sign to watch for in between. Your cancel flow is the last chance to intervene, not the first.
