What Is Revenue Churn?

Start with the recurring revenue base on the first day of the period. Two things take it down: cancellations, where an account’s whole contribution disappears, and contraction, where a customer stays but pays less after dropping seats or a plan tier. Add those up and divide by the starting base for gross revenue churn. Subtract the upgrades, added seats, and cross-sells from those same customers and you have net revenue churn, which goes negative when expansion outruns the losses.

The practical use is pipeline math. Whatever leaves must be replaced before any growth happens, so churn sets the floor for how many new deals a sales team has to close just to stay level. A company with heavy leakage needs more booked meetings each month to grow at the same pace as a stickier competitor, and that changes how aggressively it should buy pipeline versus fix retention first.

Counting customers who signed mid-period in the starting base flatters the rate by padding the denominator. Comparing a monthly rate with an annual one without converting is another quiet error, and so is reading a price increase that customers absorbed as proof of low churn. The definition also needs rules for pauses, failed payments, and customers who come back after a gap, or two analysts will report two different numbers.
