Churn rate is the percentage of customers (or revenue) you lose over a given period. The basic formula is (Lost Customers ÷ Starting Customers) × 100. It's the single most important health metric for any subscription business — even strong growth can't outrun high churn.
What is Churn Rate?
Churn rate is the percentage of customers who stop using your product or service during a specific time period — how many customers wave goodbye and walk away. Looking for typical rates by sector? See our deep dive on average churn rate benchmarks by industry.
Why Churn Rate Matters
- Cost Impact
- Acquiring new customers costs 5-25 times more than keeping existing ones
- Lost revenue from departing customers
- Wasted onboarding and marketing costs
- Growth ImpactThink of your customer base like a bucket with a hole:
- New customers = Water flowing in
- Churned customers = Water leaking out
Even with lots of new customers, high churn can keep your bucket from filling up.
- Business Health Indicator
- Shows customer satisfaction
- Indicates product-market fit
- Predicts future revenue
- Influences company valuation
How to Calculate Churn Rate
Churn Rate = (Lost Customers ÷ Starting Customers) × 100Customer churn rate
Simple Example
If you start January with 1,000 customers and lose 50 by the end:
Churn Rate = (50 ÷ 1,000) × 100 = 5%Worked example
Different Types of Churn
1. Customer Churn
When customers completely stop using your service. Example: Canceling a Netflix subscription.
2. Revenue Churn
When customers spend less money with you. Example: Downgrading from premium to basic plan.
3. Voluntary Churn
When customers choose to leave. Example: Switching to a competitor.
4. Involuntary Churn
When customers leave due to circumstances. Example: Failed payment method, company going out of business.

Churn Rate FAQ
How do you calculate churn rate?
Divide customers lost in a period by customers at the start, then multiply by 100: (Lost Customers ÷ Starting Customers) × 100. Losing 50 of 1,000 starting customers = a 5% churn rate.
What is a good churn rate?
It varies by model. SaaS small-business averages 3–5% monthly; enterprise SaaS 5–7% annually. Lower is better — see churn benchmarks by industry for detail.
What's the difference between customer churn and revenue churn?
Customer churn counts customers lost; revenue churn measures revenue lost (including downgrades). A business can lose small accounts but keep revenue flat — or vice versa.
What causes high churn?
Usually product issues (poor UX, missing features), weak customer support, or value problems (price too high, unmet expectations). Strong onboarding and proactive support are the most effective fixes.
