Open almost any SaaS growth newsletter and you'll find the same benchmark quoted as gospel: net revenue retention above 110%, churn under 1%. Those numbers are real. They're also measured on companies that, in most cases, are nowhere near the stage of the founder reading the post.
Here's what the actual stage-broken data says, and why it should change how hard you push on these numbers before you have product-market fit.
What top-quartile NRR actually looks like, by ARR
ChartMogul's SaaS Retention Report analyzed anonymized data from over 2,100 SaaS businesses and broke top-quartile net revenue retention out by ARR stage:
- $1-3M ARR: 94% top-quartile NRR
- $3-15M ARR: 99% top-quartile NRR
- $15-30M ARR: 105% top-quartile NRR
Read that again: even in the top quartile, companies at $1-3M ARR are losing ground on net revenue, not gaining it. 94% NRR means the existing customer base is shrinking in revenue terms before you add a single new logo. That's not a red flag at this stage, it's the median reality of top performers. (Source: ChartMogul SaaS Retention Report.)
Below $1M ARR, the benchmark gets less useful, not more. ChartMogul's own takeaway in the same report is that net retention is usually poor in the pre-product-market-fit stage and improves as startups grow and find fit. With a customer base small enough that two or three accounts can swing the percentage by double digits, a precise NRR target at this stage is mostly noise. If someone quotes you one for a pre-$1M ARR company, ask for their source.
Churn: the honest floor, not the aspirational one
Churn runs the opposite direction from the usual advice. ChartMogul's own benchmark data puts median monthly customer churn around 6.5% for companies under $300k ARR, far above the sub-2% figure most "good churn rate" roundups present as the standard. ChartMogul's own guidance is to aim for under 2% monthly logo churn as the business matures, and below 1% as average revenue per account (ARPA) climbs, framed explicitly as a target to grow into, not a day-one expectation. (Source: ChartMogul, "What's a good customer churn rate?")
If your monthly churn is sitting at 5-7% with under $300k ARR, that's not evidence your product has no fit. It's closer to the stage-honest median. What matters more than the raw number this early is the trend as you add engaged users, which is exactly what a retention curve that flattens is checking for.
Don't chase someone else's stage benchmark
PMFtracker reads your PMF score alongside revenue and retention signals, each against its own benchmark, so you're never comparing your $1-3M ARR company to a $20M ARR churn number by accident.

NRR and churn are both revenue-side metrics: they describe what customers who already bought in are doing with their wallets, months after the decision that matters, whether the product was worth hiring, already happened. That makes them lagging and confirming, not diagnostic. A company can have a mediocre NRR purely because it's early and small, exactly as the data above shows, while still having real product-market fit underneath.
The six metrics that actually prove PMF rank the Sean Ellis survey score as the leading indicator, with revenue retention metrics like these confirming a trend the survey already flagged. Use the survey to find out if you have fit. Use NRR and churn, read against the stage-correct benchmark above, to confirm the fit is translating into revenue, not to diagnose whether it exists.
This is also why rising MRR can lie about PMF: revenue-side numbers move for reasons, pricing, expansion, paid acquisition, that have nothing to do with whether users would be devastated to lose the product.
