What is Customer or Logo Churn?

Customer churn is the percentage of customers who stop doing business with a company over a certain period of time. It is an important metric for companies to track, as it can indicate the effectiveness of their products or services. Customer churn can also be called customer turnover.

How is customer or customer logo churn calculated?

The customer churn rate is the number of lost customers divided by the total number of customers at the beginning of the period, and then multiplied by 100 to express the result as a percentage.

For example, if a company had 100 customers at the beginning of the year, and 10 of those customers stopped doing business with the company during the year, the customer churn rate would be 10/100 * 100 = 10%.

Comparisons of customer churn rate are annual. If churn is calculated for a period of less than one year, it is generally annualised to express the rate as an annual one.

To annualise the rate, it is most accurate to convert the churn into a retention rate, then calculate to the power of the number of periods.

So for example, if 10% was the churn in a quarter, then the retention rate would be 90% per quarter, or 0.9 to the power of 4 = 0.656 per year.  This is 66% retention per year meaning an annual churn rate of 34%.

How is Customer Churn Rate used by SaaS companies?

Customer churn is typically used to measure the stickiness of a product or service and to identify areas for improvement. A high churn rate can indicate that customers are not finding value in the product, or that they are experiencing problems with it, while a low churn rate can indicate that customers are happy with the product and are likely to continue using it.

What is a good customer churn rate?

There is no “good” or “bad” customer churn rate, as it can vary greatly depending on the industry and the specific business. However, a low churn rate is favorable.

Measuring churn consistently to ensure that it is stable or decreasing is important.
