SaaS Churn Rate Calculator
How to Calculate SaaS Churn Rate
Churn rate is the percentage of customers who stop using your subscription service during a specific timeframe. For SaaS companies, monitoring this metric is vital because the cost of acquiring a new customer is significantly higher than retaining an existing one.
The Churn Rate Formula
The basic formula used in this calculator is:
(Total Lost Customers during Period / Total Customers at Start of Period) x 100
Why Churn Matters for Growth
High churn acts as a "leaky bucket." Even if your marketing team brings in hundreds of new sign-ups, your business cannot scale if you are losing an equal amount of users. A healthy SaaS churn rate typically falls between 3% and 7% annually for enterprise levels, though early-stage startups often see higher monthly rates.
Key Metrics Explained
- Retention Rate: The inverse of churn. If your churn is 5%, your retention is 95%.
- LTV (Lifetime Value): The total revenue you expect from a single customer account throughout their relationship with your company.
- Customer Lifetime: Calculated as 1 divided by the churn rate. This tells you how many months an average customer stays subscribed.
Practical Example
If you start the month with 500 customers and lose 25 by the end of the month, your calculation would be (25 / 500) = 0.05. Multiplied by 100, that is a 5% monthly churn rate. If your ARPU is $100, your LTV would be $2,000.
