How to Calculate Subscription Churn Rate

Churn rate is a critical metric for any subscription-based business, such as SaaS (Software as a Service), digital publishers, or monthly subscription boxes. It measures the percentage of subscribers who discontinue their subscriptions over a specific time period.

The Customer Churn Rate Formula

To calculate the basic customer churn rate, you need two primary numbers: the number of customers at the beginning of the period and the number of customers who left (churned) during that same period.

Churn Rate = (Lost Customers / Starting Customers) x 100

Example Calculation

Imagine your SaaS company starts the month of January with 500 active subscribers. During January, 25 customers cancel their subscriptions.

  • Starting Customers: 500
  • Lost Customers: 25
  • Calculation: (25 / 500) = 0.05
  • Churn Rate: 5%

Revenue Churn (MRR Churn)

While customer churn tells you how many people left, Revenue Churn (or MRR Churn) tells you the financial impact. This is vital if you have multiple pricing tiers. If you lose 10 customers on a $10/month plan, it is much less damaging than losing 10 customers on a $500/month enterprise plan.

Revenue Churn Formula: (Churned MRR / Starting MRR) x 100

Why Monitoring Churn is Essential

High churn rates indicate that customers aren't finding enough value in your product, or that your competitors are offering a better deal. Generally, a "good" churn rate for B2B SaaS is between 3% and 5% annually, while B2C companies often see higher monthly churn rates.

Steps to Reduce Churn:

  1. Improve Onboarding: Ensure new users understand how to use the product immediately.
  2. Customer Feedback: Survey churning customers to find out why they are leaving.
  3. Engagement: Regularly provide value through updates, newsletters, and new features.
  4. Dunning Management: Automatically retry failed credit card payments to prevent involuntary churn.
