Annual Recurring Revenue (ARR)
Annual Recurring Revenue (ARR) is the normalized annualized run-rate of recurring revenue — capturing the ongoing subscription revenue value of the business at a point in time — the dominant metric for SaaS valuation and growth analysis.
Why This Matters
ARR is the master metric of B2B SaaS business analysis. Calculated as the sum of all active subscription revenue annualized — a SaaS business with 100 customers paying $10K/year each has $1M ARR. ARR growth rate (typically 30-100%+ for venture-backed SaaS) drives valuation multiples and growth investment decisions. Net Revenue Retention (NRR) tracks ARR base expansion through upsells minus contractions and churn — strong NRR (110%+) indicates sustainable expansion economics. ARR-based metrics (ARR per employee, ARR per rep, CAC payback period in ARR terms) form the foundational analytical framework for SaaS operations.
Frequently Asked Questions
Frequently Asked Questions
How is ARR different from revenue?
Revenue is what's recognized in financial statements (usually monthly/quarterly recognition of contract value). ARR is annualized run-rate of recurring revenue at point in time — captures the ongoing business value rather than period revenue recognition. A SaaS business signing $300K three-year contract recognizes $100K revenue per year but adds $100K ARR immediately.
What ARR growth rate is healthy for B2B SaaS?
Wildly varying by stage and segment. Early stage venture-backed SaaS often 100-300% growth. Growth stage often 50-100%. Maturity stage often 20-40%. Enterprise SaaS often slower-but-steady 25-50% growth. Public SaaS often 15-30% mature growth. Benchmark against stage-appropriate cohorts.
