Churn Rate Calculator

Calculate customer churn rate, retention rate, and analyze customer lifecycle to improve retention strategies.
Decision Context
Page-specific guidance for using this result in a real planning decision.

Use this page to estimate how quickly customers leave a product or service and how that attrition affects growth assumptions.

It is particularly useful for subscriptions, membership businesses, and recurring-revenue models where customer retention drives long-term value.

Churn should be reviewed with retention and acquisition cost together, because a business can look like it is growing while quietly replacing lost customers at high cost.

Churn & Retention Rates

Churn rate measures the percentage of customers who stop using your product/service. Retention rate shows the percentage who stay.
Churn Rate = (Customers Lost ÷ Total Customers) × 100% Retention Rate = 100% - Churn Rate

Variables:

Churn Rate% of customers lost
Retention Rate% of customers retained
Total CustomersCustomers at start of period
Customers LostCustomers who cancelled/left

Example

SaaS Business Example

Inputs:

Total Customers:1,000 customers
Customers Lost:50 customers (in one month)

Steps:

  1. 1.Churn Rate = (50 ÷ 1,000) × 100 = 5%
  2. 2.Retention Rate = 100% - 5% = 95%
  3. 3.Monthly churn of 5% is average for SaaS
  4. 4.At this rate, you'd have 540 customers after 12 months without new acquisitions
Result:
5% monthly churn rate, 95% retention rate

Frequently Asked Questions

What's a good churn rate?

Varies by industry. SaaS: 2-8% monthly is typical, <5% is good. B2C services: 5-7%. Enterprise: <1-2%. Lower is always better. Negative churn (expansion > churn) is ideal.

Monthly vs annual churn rate?

Monthly churn is more useful for tracking trends. Annual churn = 1 - (1 - monthly rate)^12. A 5% monthly churn = 46% annual churn, which compounds significantly.

How do I reduce churn?

Improve onboarding, provide excellent support, add value regularly, identify at-risk customers early, offer incentives to stay, build community, and address root causes through exit surveys.
