A simple way to calculate churn is by dividing the number of clients in a certain time period by the number of churn clients at the beginning of that time period. This could be monthly, quarterly, or however you choose.

Churn Clients


Another way to determine the churn rate produces more precise data and takes into account the variation of clients throughout the selected time period.

(Customers1 + Customersn) / 2

Other ways to calculate the churn rate exist but these two methods are the most commonly used. Ideally, your rate should be zero or negative. However, for small and medium businesses something around 3-5% monthly is acceptable. Annually, it should be lower than 10%. The churn rate should be less than 1% for enterprises with high ticket offers.

A low churn rate means a higher client retention rate!

Monthly Recurring Revenue and Expansion (MRR)

Monthly Recurring Revenue Expansion or MRR is the monthly revenue that comes from clients paying for a subscription service, cross-sell and upsell. An MRR Expansion rate is the MRR from your current month divided by the MRR from the previous month. This provides information on how much your business is actually earning from clients, excluding new customers.

Customer Lifetime Value or CLV is the projected revenue you expect to receive from a customer. Knowing this percentage will help you identify how much you should spend to get a new customer, while simultaneously identifying who your best customers are and your average profit.
