01
Net revenue churn asks whether expansion from the starting cohort covers churned and contracted MRR. Negative net churn is the healthy SaaS signal: existing customers grow faster than they leak.
This page's framing is a net-churn desk, with an expansion-credit peel, a cover-ratio companion, and an NDR cue. It is not gross logo churn's annualize/survival strip, not monthly logo pulse, not the MRR waterfall that includes new logos, and not the full NDR end÷start board.
Decision framing: “After expansion credit, is the starting cohort still leaking recurring dollars?”

Gross loss stacks churned MRR (logos that left) and contraction (downgrades that stayed). Expansion credit is uplift from the same starting book. Net loss = gross loss − expansion. New-logo revenue is deliberately excluded so acquisition cannot mask cohort health.
Tip: load Negative net. Expansion $8k against $4k gross loss flips the desk below zero.
03
Cover ratio = expansion ÷ (churned + contraction). Above 1× means expansion more than replaces gross recurring loss. You can have a strong cover ratio and still want NDR depth when mix, multi-product, and annual plans complicate the story.
Contraction share of begin keeps downgrades visible so they are not silently folded into “churn” without a label.
04
Under a matching cohort definition, NDR ≈ 100% − net revenue churn. The cue is a quick retention sketch, not a full NDR calculator. Edge cases, beginning/ending stock framing, and peer storytelling live on net dollar retention.
05
Net churn, cover ratio, and NDR cue.
Example: begin $100k, churned $3k, contraction $1k, expansion $8k → gross loss $4k → net churn −4% → cover 2× → NDR cue 104%.

Sibling boards when the job is logos, month waterfall, dollars, or full NDR.
07
Scenario A: Negative net. Expansion outruns churned + contraction. Desk prints negative net churn and cover above 1×.
Load Leaking: gross loss still wins after a modest expansion credit.
Scenario B: Balanced. Expansion roughly matches gross loss. Net sits near zero; NDR cue near 100%.
Scenario C: Critical. Thin expansion against heavy churned MRR. Cover ratio collapses; hand off to retention and revenue churn diagnostics.
Scenario D: Need new logos in the story. Use the MRR waterfall when net-new including acquisition is the question.

It closes a net revenue churn desk from beginning MRR, churned MRR, contraction, and expansion. An expansion-credit peel shows gross loss versus expansion offset, a cover-ratio companion compares expansion to gross loss, and an NDR cue prints 100% − net churn as a quick retention sketch.
Net revenue churn = (churned MRR + contraction − expansion) ÷ beginning MRR. Negative net churn means expansion from the starting cohort more than offset losses. New-logo revenue is excluded here.
Net churn is a starting-cohort story. New logos belong in net-new MRR on the MRR waterfall. Mixing them in hides whether existing customers are expanding enough to cover churn.
Cover ratio = expansion ÷ (churned + contraction). Above 1× means expansion more than covers gross recurring loss from the cohort. It is a companion, not a substitute for net churn %.
Gross churn owns logo loss without expansion credit. MRR owns month movement including new logos. NDR owns ending÷starting cohort revenue in depth. This page owns net revenue churn % with expansion credit and cover ratio.
No. The cue is 100% − net churn under a matching cohort definition. Full NDR framing and edge cases live on the net dollar retention board.
