What is ARR (Annual Recurring Revenue)?
Annual Recurring Revenue (ARR) is the annualised view of a SaaS company's subscription revenue, calculated by multiplying MRR by 12. ARR is the standard metric used by investors, analysts, and boards to assess the scale and growth trajectory of subscription businesses. It is particularly important for enterprise SaaS where annual contracts are the norm and revenue recognition spans the full year.
Formula
ARR = MRR x 12For businesses that sell annual contracts directly, ARR can also be calculated as the sum of all annual contract values. Multi-year contracts are typically annualised (divide total contract value by contract length in years). ARR growth rate = (Current ARR - Previous ARR) / Previous ARR x 100%.
Benchmarks and interpretation
- ARR measures recurring revenue scale; it does not establish product-market fit or funding readiness
- Review ARR alongside retention, growth, margins, and acquisition economics
- Compare ARR growth over consistent periods and within a similar company stage
- Valuation multiples depend on growth, margins, risk, and market conditions
- Rule of 40 is a common growth-and-profitability heuristic, not a universal test of SaaS health
When to use ARR
- Fundraising conversations and investor due diligence reporting
- Annual planning and long-range financial modelling
- Sales quota setting and territory planning for enterprise teams
- Benchmarking growth rate against SaaS industry cohorts
- Treating ARR as cash in the bank - ARR is a forward-looking metric, not a measure of collected revenue
- Including non-recurring revenue such as implementation fees or training in ARR calculations
- Confusing ARR, which covers the recurring revenue base, with ACV (Annual Contract Value), which describes the annualized value of a contract
- Report ARR alongside Net Revenue Retention to show quality of the ARR base, not just absolute size
- Break ARR into new logo ARR vs expansion ARR to understand how much growth is customer acquisition vs land-and-expand
- Model ARR cohort retention curves to forecast future ARR from existing customers
