SaaS churn rate is the percentage of customers or revenue lost over a period. It measures how fast a subscription business loses customers (customer churn) or recurring revenue (revenue churn).
Churn rate is the headline measure of how fast a subscription business leaks customers or revenue. It is the counterweight to growth: a company can add new customers quickly and still stall if churn is high. For SaaS, where revenue is recurring, controlling churn is as important as winning new business.
How SaaS churn rate works
Churn rate is the share lost over a period, and it comes in two forms. Customer churn rate is customers lost divided by customers at the start of the period. Revenue churn rate is recurring revenue lost (from cancellations and downgrades) divided by recurring revenue at the start.
For example, starting a month with 500 customers and losing 15 gives a 3 percent monthly customer churn. Starting with $100,000 MRR and losing $4,000 to cancellations and downgrades gives 4 percent gross revenue churn. Revenue churn can differ sharply from customer churn when lost customers are larger or smaller than average.
SaaS churn rate examples
A product loses 2 percent of customers monthly but only 1 percent of revenue, because the churned accounts are small. Another loses 1 percent of customers but 5 percent of revenue, because a few large accounts left, a more dangerous signal that customer churn alone would hide.
Annualizing matters too: 3 percent monthly churn compounds to roughly a third of customers lost over a year, which reframes how urgent it is.

| Best paired with | Revenue churn | Net revenue retention |
| Signal | Logo loss | Revenue impact |
Benefits & when to use it
Churn rate is essential for any subscription or usage business, because it determines whether growth compounds or leaks away. Watching customer and revenue churn together reveals whether the business is losing many small accounts or a few large ones, which call for different responses.
Churn pairs naturally with net revenue retention, which folds in expansion to show whether the existing base grows or shrinks net of churn. For usage products, “churn” also includes customers who quietly reduce consumption, not just those who cancel.
FAQ
How do you calculate SaaS churn rate?
Divide what was lost during the period by what you started with. Customer churn rate is customers lost ÷ customers at the start; revenue churn rate is recurring revenue lost ÷ recurring revenue at the start, expressed as a percentage.
What is the difference between customer churn and revenue churn?
Customer churn counts logos lost; revenue churn counts recurring revenue lost. They diverge when churned accounts are larger or smaller than average, so tracking both avoids a misleading read.
What is a good SaaS churn rate?
It varies by segment, but lower is better and benchmarks differ for SMB versus enterprise. Many SaaS businesses target low single-digit monthly churn; enterprise products typically run much lower than self-serve SMB.
How Credyt handles SaaS churn rate
For usage-based products, churn is not just cancellations; it is declining consumption. Because Credyt meters usage per customer in real time, it surfaces the early signal that an account is winding down (falling usage and balance draw) before it formally churns, giving teams the data to intervene while the customer is still active.
