The problem
What is churn rate and how do you calculate it?
Churn rate (attrition rate) is the percentage of clients you lose in a period. Formula: (Clients lost / Clients at start) × 100. If you started the quarter with 200 clients and lost 10, your quarterly churn is 5%. Churn impacts net revenue retention directly; Paddle quantifies this relationship in how NRR reveals the true cost of churn.
In B2B, 5-7% annual churn is considered acceptable. Above 10%, you have a serious problem: you are losing clients faster than you can acquire new ones.
The most dangerous thing about churn is that many companies do not measure it until it is too late. By the time you notice the revenue drop, you have already lost accounts you could have saved with proactive retention strategies.

Causes
The 4 main causes of B2B churn
Before reducing churn, you need to understand why it happens:
Lack of proactive follow-up
The client feels you are not paying attention. You only contact them to collect or when there is a problem.

Poor onboarding
The client does not understand how to get value from your product in the first 90 days. With a Customer Success team this reduces by 67%.

Unresolved support issues
Open tickets, long response times, feeling that nobody listens.

Changing needs without adaptation
The client grows, their needs change and you do not offer upselling to keep up.
