What is customer churn? Types, rates, and benchmarks

Every SaaS company loses customers. What matters is whether you know the rate, the type, and whether your number is normal for how you sell.

This page defines churn and benchmarks. For what to do when accounts slip, see how to reduce SaaS churn. For dollar impact after retention, see net revenue retention.

Types of churn

Not all churn shares the same cause or fix.

Voluntary churn is an active cancel: competitor, budget cut, or outgrew the product. Fix product, onboarding, or relationship gaps.

Involuntary churn is payment failure: expired card, insufficient funds, billing error. Often 20-40% of churn. Fix with dunning, reminders, and grace periods.

Silent churn is gradual fade without complaints. Usage drops before anyone files a ticket. See silent churn for signs and 6 early warning signs for a checklist.

How to calculate churn

Track two formulas every month.

Logo churn counts accounts lost. Revenue churn counts MRR lost. They diverge often: 3% logo churn with 8% revenue churn means bigger accounts are leaving. High logo churn with low revenue churn may mean small accounts are exiting.

Example: 1,000 customers at month start, 30 cancel → 3% monthly customer churn rate.

Is my churn rate good?

Benchmarks depend on how hard it is to leave. Enterprise deals have switching cost. Self-serve users can cancel in minutes.

How to read the table:

• Good: Healthy for that segment. Keep measuring cohorts, do not coast.
• Average: Common range. Worth understanding drivers by plan and tenure.
• Concerning: Likely a product, onboarding, or payment problem unless you are deliberately optimizing for volume at the low end.

Enterprise monthly churn under 0.5% is strong. PLG products often run 3-5% monthly and can still work if acquisition and expansion economics fit.

Compare to your segment and contract length, not a headline "industry average."

Why churn compounds

Churn erodes the base you grow from. Each month, the same percentage applies to less revenue.

Worked example: $100K MRR, 5% monthly churn, no new sales.

• Month 1: $95K
• Month 3: ~$85.7K
• Month 6: ~$73.5K
• Month 12: ~$54K

You keep about 54% of the starting base in a year, not 40% (5% × 12). A 1-point drop (5% to 4% monthly) leaves about $61K at month 12 instead of $54K.

Lost customers also stop expanding, referring, and becoming case studies. That hidden cost shows up in NRR over time.

Measuring churn without fooling yourself

Monthly vs annual. 5% annual churn is not 5% ÷ 12 monthly. Convert before comparing companies on different reporting cycles.

Cohorts. New customers churn more than mature ones. Rising overall churn can hide improving retention on older cohorts. Segment by signup month.

Seasonality. Budget cycles and renewals can spike one month. Use trailing averages for strategy, not panic on a single print.

Logo vs revenue. Low logo churn plus high revenue churn means whales are leaving. High logo churn plus low revenue churn may mean small accounts are churning. Different problems, different fixes.

Churn starts before cancellation

Cancellation is usually the last step. Usage often fades for weeks first: longer gaps, shorter sessions, narrower features. That pattern is behavioral decay.

A customer health score rolls usage into one trend so you can act in the monitor band, not at renewal week. For save tactics by risk level, see how to reduce SaaS churn.
