Every year I revisit which SaaS benchmarks actually matter for the work I do. 2026 is shaping up differently than the last couple of years, and finance teams should pay attention. **Efficiency is still the headline.** The Rule of 40 has become table stakes. Investors and boards now want to see Rule of 50 or better from growth-stage companies. If your FP&A team isn't tracking burn multiple alongside growth rate, you're behind. **Net revenue retention is under pressure.** With tighter budgets across the board, NRR is slipping for a lot of mid-market SaaS companies. The benchmark reports from Bessemer, KeyBanc, and OpenView all show median NRR trending down. That's a signal to watch, especially if your company has been leaning on expansion revenue to hit targets. **AI-native metrics are emerging.** We're starting to see benchmarks around cost-per-AI-query, AI feature adoption rates, and the revenue contribution of AI-powered tiers. These are still early, but if you're at a company shipping AI features, start instrumenting this data now. You'll need it in board conversations by Q3. **Payback period is king again.** CAC payback under 18 months is the new bar. Anything longer and you're going to face hard questions about go-to-market efficiency. I've been organizing my own thinking on this in my [[notebook/Thinking About SaaS Metrics|SaaS metrics note]], and pressure-testing assumptions using the variance analysis framework I've been refining. If you're in SaaS finance, bookmark the Bessemer Cloud Index and the KeyBanc annual survey. They're the two sources I come back to most. ← [[Signal|Back to /signal]]
