Logo, revenue, and NRR.

Three churn views tell the real story. Logo churn counts customers lost. Revenue churn counts dollars lost. Net revenue retention ties both to expansion and contraction. A SaaS company with 3 percent logo churn, 2 percent revenue churn, and 115 percent NRR is compounding without adding customers; the same company with 3 percent logo churn, 5 percent revenue churn, and 94 percent NRR is bleeding dollars faster than logos because churn concentrates on bigger accounts. The calculator above surfaces all three simultaneously.

Best-in-class benchmarks from OpenView and ChartMogul SaaS Retention Report: enterprise SaaS runs 0.3 to 1 percent monthly logo churn, mid-market 1 to 2 percent, SMB 3 to 5 percent. NRR above 110 percent is the threshold Wall Street uses to mark premium multiples; above 130 is the Snowflake/Datadog band.

Five answers.

What is the difference between logo churn and revenue churn?

Logo churn (also called customer churn) is the percentage of customers who cancel in a given period: cancellations divided by customers at start of period. Revenue churn (also called gross revenue churn) is the percentage of starting MRR lost to cancellations and downgrades. The two can diverge sharply when churn concentrates on small accounts (low revenue churn, higher logo churn) or on enterprise accounts (high revenue churn, lower logo churn). Both matter; NRR ties them together.

What is Net Revenue Retention and why does it matter?

NRR is (starting MRR + expansion - contraction - churn) divided by starting MRR, expressed as a percentage. It is the single best indicator of SaaS health because it captures churn and expansion in one number. NRR above 100 percent means the existing book of business is growing on its own before any new acquisition; NRR of 120 percent means existing customers are worth 20 percent more this month than last with zero new sales. Best-in-class public SaaS companies (Snowflake, Datadog, ZoomInfo) have historically posted NRR in the 130 to 160 percent range.

What is a healthy monthly churn rate in 2026?

Under 1 percent monthly is excellent (annualized roughly 11 to 12 percent). 1 to 2 percent is healthy for most B2B SaaS. 3 to 5 percent is the zone most SMB SaaS lives in. Above 5 percent monthly signals product-market fit issues and annualized churn approaches 50 percent. Consumer subscription typically runs higher (5 to 10 percent monthly); enterprise typically runs lower (0.3 to 1 percent). These benchmarks come from ChartMogul and OpenView's annual SaaS reports.

How does monthly churn translate to annual churn?

Annual churn is not simply monthly churn times 12. The correct formula is 1 minus (1 minus monthly churn) to the twelfth power. Two percent monthly churn equals roughly 21.5 percent annual churn; five percent monthly equals 46 percent annual. This compounding is why reducing monthly churn from 5 percent to 3 percent is more valuable than it looks — it cuts annual churn from 46 percent to 31 percent, a 15-point improvement in retention.
