Net Revenue Retention vs Churn: Logo, Revenue, and NRR
Logo churn counts customers lost. Revenue churn counts recurring revenue lost from downgrades and cancels. Net revenue retention (NRR) starts from a cohort’s recurring revenue and adds expansion, then subtracts contraction and churn — so NRR can exceed 100% when existing customers grow faster than others shrink or leave.

Three related but different metrics
| Metric | What it measures |
|---|---|
| Logo churn | % of customers who cancel in a period |
| Revenue churn (gross) | % of recurring revenue lost to cancel/downgrade (before expansion) |
| NRR (net revenue retention) | Ending recurring revenue from a starting cohort ÷ starting recurring revenue (includes expansion) |
Formulas and numeric example
Start of month cohort MRR: $100,000 across 100 customers. During the month: $8,000 lost to churn/downgrades, $15,000 gained from upgrades/expansion. Ending MRR from that same cohort: $107,000.
Logo churn example: if 5 of 100 customers cancel, logo churn = 5%.
Gross revenue churn ≈ $8,000 ÷ $100,000 = 8%.
NRR ≈ $107,000 ÷ $100,000 = 107%.
Same month can show “fine” logo churn while revenue churn is worse (large accounts leaving) — or strong NRR while logos still churn if remaining accounts expand.
Why NRR matters
NRR tells you whether your existing base is a growth engine. High NRR means you can grow without relying only on new logos — which usually improves capital efficiency and makes CAC less existential. Investors in B2B SaaS often scrutinize NRR because it encodes retention quality plus expansion.
- NRR > 100%: expansion outweighs contraction and churn in the cohort.
- NRR < 100%: you must replace lost revenue with new customers just to stand still.
- Always report the period (monthly/annualized) and cohort definition.
Common reporting mistakes
- Mixing logo churn with revenue churn in one unlabeled chart.
- Including new-customer revenue inside an NRR cohort (NRR is about existing customers).
- Annualizing a noisy single month without showing the underlying volatility.
- Hiding contraction by only showing logo logos retained.
Put this into practice on Bowora
Retention quality eventually shows up in durable recurring revenue. When you publish verified MRR, keep internal NRR and churn honest so public trust and private diligence match.
Common questions
- What is the difference between logo churn and revenue churn?
- Logo churn is the percentage of customers who leave. Revenue churn is the percentage of recurring revenue lost to cancels and downgrades. Losing one large customer can make revenue churn much worse than logo churn.
- What is net revenue retention (NRR)?
- NRR measures how recurring revenue from an existing customer cohort changes over a period, including expansion, contraction, and churn. It can exceed 100% when upgrades outweigh losses.
- Can NRR be over 100% if customers still churn?
- Yes. If remaining customers expand enough to more than replace lost revenue, NRR can be above 100% even while some logos cancel.
- Why do investors care about NRR?
- Strong NRR means the installed base grows on its own, which usually supports more efficient growth and a healthier response to CAC and burn scrutiny.
