Revenue Churn Rate

Revenue churn rate is the percentage of recurring revenue you lose from existing customers in a period — through cancellations and downgrades — relative to the revenue you started with. Where customer churn counts the logos that leave, revenue churn weighs them: losing one $2,000 account is twenty times the damage of losing a $100 one, and only the dollar view shows it.

It comes in two flavours. Gross revenue churn counts only the losses. Net revenue churn subtracts expansion from those losses — and can go negative, the celebrated state where upgrades from existing customers outgrow everything churn takes away.

Gross revenue churn is churned MRR plus contraction MRR, divided by MRR at the start of the period. Losing $1,200 to cancellations and $800 to downgrades from a $20,000 base is 10% gross revenue churn. Net revenue churn subtracts expansion first: with $3,000 of upgrades, the same month nets to −5% — negative churn.

The rate is the mirror of your retention numbers: gross revenue churn of 10% is a GRR of 90%, and net revenue churn of −5% is an NRR of 105%. Same arithmetic, opposite sign — pick one framing for your reporting and stay consistent.

For SMB-focused SaaS, gross revenue churn of 2–4% a month is common and under 2% is strong; enterprise businesses should see well under 1%. Anything approaching 10% a month means the base halves in a year without new sales — a leak no acquisition engine outruns for long.

Watch gross and net together. Net churn is the headline, but expansion can mask a serious gross leak for quarters — a business at −1% net on 8% gross is far more fragile than one at −1% net on 2% gross, because its good number depends entirely on upgrades continuing.

Fix the definitions before comparing months — each choice moves the rate:

• Do downgrades count in churn, or only full cancellations? (Convention: both — that is what separates this from customer churn.)
• Gross or net as the headline number — and does the board see both?
• Is the denominator start-of-period MRR only, excluding revenue added during the period?
