Revenue Churn Rate Calculator
Measure MRR churn and net revenue retention: gross revenue churn, net churn after expansion, and the NRR that decides if you grow without new sales.
How it works
Gross revenue churn % = MRR lost ÷ starting MRR × 100 · Net revenue churn % = (MRR lost − expansion MRR) ÷ starting MRR × 100 · NRR % = (starting − lost + expansion) ÷ starting × 100
Revenue churn tracks lost recurring revenue rather than lost customer counts, which matters when the accounts you lose are larger or smaller than average. Gross revenue churn counts only losses from cancellations and downgrades. Net revenue churn subtracts expansion revenue from upgrades — and when expansion outweighs losses, net revenue retention (NRR) exceeds 100%, meaning your existing customer base grows revenue on its own before any new sales.
Worked example
Starting the month at $50,000 MRR, you lose $2,500 to cancellations and downgrades but gain $1,000 from upgrades. Gross churn is 2,500 ÷ 50,000 = 5%; net churn is (2,500 − 1,000) ÷ 50,000 = 3%; and NRR is (50,000 − 2,500 + 1,000) ÷ 50,000 = 97%.
Frequently asked questions
What is the difference between revenue churn and customer churn?
Customer churn counts how many customers leave; revenue churn measures how much recurring revenue you lose. They diverge when churned accounts are bigger or smaller than average — losing a few large accounts can mean low customer churn but high revenue churn.
What is net revenue retention (NRR)?
NRR is the recurring revenue you keep from existing customers, including upgrades but excluding new customers. Above 100% means expansion more than offsets churn, so revenue grows even with zero new sales — a hallmark of strong SaaS businesses.
What is a good revenue churn rate?
For SaaS, gross monthly revenue churn under about 1% is strong; best-in-class companies achieve negative net churn (NRR above 100%). Consumer and SMB products typically churn faster than enterprise.
