SaaS Churn Benchmarks — What Counts as Good
Churn is the number every subscription business watches, and also the one most often quoted without saying which churn. “We’re at 5%” could be a healthy month or an existential problem depending on what is being measured. Here is how the pieces fit together.
Two families: customers and revenue
Customer churn (also called logo churn) is simple: customers lost in a period ÷ customers you had at the start. If 500 customers became 475, that is 5% customer churn for the month.
Revenue churn measures money, not headcount, and it splits into two versions that tell different stories.
- Gross revenue churn = (revenue lost to cancellations + revenue lost to downgrades) ÷ revenue at the start of the period. It only ever counts losses. It cannot be negative.
- Net revenue churn starts from the same losses but subtracts the extra revenue from existing customers who upgraded. When upgrades outweigh losses, net revenue churn goes below zero — your existing customer base is growing on its own.
A business can have ugly gross churn and still post negative net churn if a core of customers keeps expanding. That is common in tools that grow with a customer’s usage. It is also why you should always ask which number someone means.
Retention is the same idea, counted upward
Retention metrics are churn viewed from the other side.
- Gross revenue retention (GRR) = the share of starting revenue you keep after downgrades and cancellations. It caps at 100%.
- Net revenue retention (NRR) = GRR plus the revenue from upgrades. It can exceed 100%.
NRR above 100% is the single clearest sign of a durable business: it means that even with zero new sales, revenue would grow next year.
Rough targets
These are norms for a company selling to small and mid-sized businesses. Enterprise-focused companies run much lower churn; very early-stage companies swing wildly month to month and should look at a rolling three-month average.
| Metric | Healthy | Watch | Poor |
|---|---|---|---|
| Gross revenue churn (monthly) | under 3% | 3–6% | over 6% |
| Net revenue churn (monthly) | 0% or below | 0–3% | over 3% |
| Customer / logo churn (monthly) | under 3% | 3–6% | over 6% |
| Net revenue retention | 105%+ | 90–105% | under 90% |
| Gross revenue retention | 90%+ | 80–90% | under 80% |
A monthly churn rate compounds fast. 5% a month is not “95% retained” over a year — it is closer to 54%. Small improvements in a monthly rate are worth a lot.
Churn is downstream of a few other numbers
If churn is creeping up, the metrics around it usually explain why:
- Falling ARPA (average revenue per account) alongside steady logo churn means your remaining customers are smaller — you may be losing the good ones.
- A low Quick Ratio — new plus upgrade revenue divided by cancelled plus downgrade revenue — under about 2 means you are refilling a leaky bucket rather than growing.
- Rising CAC payback stretches the time before a customer is profitable, so churn hurts more per lost account.
See where your numbers land
Put one month of revenue movement and customer counts into the SaaS metrics calculator. It works out gross and net churn, NRR, GRR, LTV, CAC and the Quick Ratio together, and flags each against these benchmarks — which is more useful than any single figure on its own.
