Net Revenue Retention Above 100% (and Why NRR Lies)

A framework for using existing-customer expansion to offset the automatic growth of cancellations, plus a caution about NRR's blind spots. Because churn scales with size, you need a counter-force that also scales: existing customers paying more (NRR above 100%). But NRR hides logo attrition and overstates recovery, so pair it with logo churn. Use it to reason about durable, scalable growth.
Origin
Cohen ties NRR back to the cancellation-ceiling model: expansion is the force that scales with your base to offset churn. He argues NRR is necessary (median SaaS IPOs are 119%; nearly all public SaaS exceed 100%) but flawed, using a stock-market loss-recovery analogy to show a 20% loss needs a 25% gain to break even.
Core principles
- 01Expansion revenue scales with your customer base, so it can offset churn that also scales
- 02NRR must exceed 100% for a large SaaS company to be possible
- 03A percentage loss requires a larger percentage gain to recover — so equal up/down NRR still leaves you behind
- 04NRR ignores that if logo churn is too high, too few customers remain to expand
- 05Customers should agree they're getting more value when they pay more — ideally far more
How to run it
- 1
Compute NRR on the existing cohort
Take the revenue of current customers and measure what remains a year later — down from cancels and downgrades, up from upgrades and usage. It can end above where it started.
Watch out NRR only makes sense for revenue, not logo count, because logo count can only go down.

Get NRR above 100%
Design tiers, usage-based pricing, or new features so expansion beats churn and downgrades. Nearly all successful public SaaS exceeds 100%; the IPO median is 119%.
Pro tip Only about two of 100+ public SaaS companies have NRR below 100%, and their financials are poor.

Cross-check against logo churn
Don't treat NRR as a golden metric. If logo churn is too high, there aren't enough remaining customers to expand, so positive NRR can mask a shrinking base.
Pro tip A 20% churn loss offset by a 20% expansion gain only recovers to 96%, not 100% — the math is asymmetric.
Watch out Plug the logo-churn hole first; NRR is question three, after churn is under control.

Measure and grow the customer's perceived value
Instead of only tracking internal usage metrics, measure how much value the customer believes they're getting, then create more value and split it with them via price.
Pro tip The customer should feel the value rises faster than the price ('price doubled but I'm getting five times the value').
Watch out If perceived value isn't rising and you raise prices anyway, customers start shopping for alternatives — we've all done it.
In the wild
A stock at $100 that drops 20% sits at $80; a 20% gain on $80 is only $96. It takes a 25% gain to recover a 20% loss.
→ Shows NRR overstates health — equal-looking churn and expansion percentages still leave the cohort below par.
Of 100+ public SaaS companies, only ~2 have NRR under 100%, and those have bad valuations; the median at IPO is 119%.
→ Demonstrates expansion above churn is effectively mandatory for large-scale SaaS growth.
Common mistakes
Treating NRR as the single golden metric
Positive NRR with high logo churn is a trap — too few customers remain to expand, and NRR undercounts the damage.
Adding features and forcing higher prices
If the customer doesn't perceive more value than the price rise, they'll leave; expansion must feel fair to the customer, not just convenient for you.
Is it for you?
Best for
SaaS founders and finance leaders designing expansion pricing to sustain durable growth
Not ideal for
Consumer or small-business products where accounts rarely expand — there the answer is referrals or a second product, not NRR
From the transcript
“the median for a IPOed SAS company like at IPO the median NR is 119%”
“a loss of 20% requires a gain of 25% to get back to where you were. This is why NR isn't quite right”
“how do we create more value for the customer and then split that with them”
