Monthly / Annual Recurring Revenue — the core revenue metric for subscription businesses.
📊 Benchmark
Growth rate varies by stage. Seed-stage SaaS targets 15–20% monthly; growth-stage targets 100–200% YoY ARR.
💡 PM decisions
Which features drive new MRR? Which drive expansion? Which prevent churn?
2. NRR (Net Revenue Retention)
Revenue from existing customers after churn + contraction + expansion. >100% means you grow from existing base alone.
📊 Benchmark
Best SaaS: 130%+. Healthy: 110–130%. Concerning: <100%. Below 90% = leaky bucket.
💡 PM decisions
Invest in expansion features (more seats, higher tier) vs core retention?
3. GRR (Gross Revenue Retention)
Revenue retained before expansion — pure measure of churn. Tells you if customers are leaving.
📊 Benchmark
Enterprise: 95%+. Mid-market: 90%+. SMB: 80%+. Below that = serious retention problem.
💡 PM decisions
Prioritise churn reduction, onboarding improvements, product stickiness.
4. CAC (Customer Acquisition Cost)
Total cost (marketing + sales) to acquire one new paying customer.
📊 Benchmark
Should be payback-ready within 12 months of ARR. Longer = unsustainable unit economics.
💡 PM decisions
Which features reduce CAC via product-led growth? Which channels are efficient?
5. LTV (Customer Lifetime Value)
Total revenue expected from a customer over their lifetime, accounting for churn.
📊 Benchmark
LTV:CAC ratio of 3:1 is healthy. 1:1 is burning money. 5:1+ = under-investing in growth.
💡 PM decisions
Which user segments have highest LTV? Design product experience to drive them deeper.
6. CAC Payback Period
Months of ARR needed to recoup CAC. Cash flow proxy.
📊 Benchmark
<12 months = healthy. 12–18 = acceptable at scale. >18 = dangerous at startup stage.
💡 PM decisions
Does this feature accelerate onboarding-to-paid? Does it make CAC payback faster?
7. Logo Retention vs Revenue Retention
% of customers retained (logo) vs % of revenue retained. Can diverge.
📊 Benchmark
Logo retention often lower than revenue retention (small customers churn more; big ones stay).
💡 PM decisions
If logos are churning but revenue isn't, are you serving only large customers? Is that intentional?
8. PQL (Product Qualified Lead)
A user who's shown product usage signal they're ready to buy. PLG signal.
📊 Benchmark
PQL conversion to paid: 25–40% (much higher than MQL conversion of 5–10%).
💡 PM decisions
Which in-product behaviours predict conversion? Build towards those signals.
FAQ
Which SaaS metric matters most?
NRR. It captures the health of your existing base and is the single strongest predictor of long-term SaaS success. SaaS companies with NRR >120% compound revenue even without new acquisition. Below 100% NRR means you're losing revenue from existing customers faster than expanding it — a structural problem no growth can outrun.
Do PMs need to own SaaS metrics directly?
Share ownership. Revenue-level metrics (MRR, NRR, CAC) are typically owned by growth/marketing or finance. Product-level metrics (feature adoption, PQLs, activation) are owned by PMs. Great PMs connect their product metrics to revenue metrics — showing how their work moves NRR, reduces CAC payback, or grows LTV.
