ARR (Annual Recurring Revenue) in depth
Annual Recurring Revenue is the 12-month projection of current subscription revenue. Most companies calculate ARR as MRR * 12, but enterprise SaaS often calculates it directly from annual contract value (ACV) because month-to-month volatility is less meaningful for deals measured in years. ARR is the headline number investors use to size a SaaS business because it smooths out monthly noise and aligns with typical B2B contract durations. The important caveat is that ARR is a snapshot, not a forward guarantee: it assumes zero churn over the next 12 months, which is almost never true. Pair it with gross and net revenue retention to tell the full story. ARR growth rate, ARR per employee, and the Rule of 40 (ARR growth percentage plus free cash flow margin) are the three derived metrics most frequently used to benchmark SaaS businesses against peers and investor expectations.
ARR = MRR * 12 (or sum of ACV across all active annual contracts)
Examples in practice
A SaaS with $150k MRR reports $1.8M ARR. With 92% gross revenue retention, the expected ARR 12 months from now from the current book alone is closer to $1.66M.
An enterprise SaaS with 40 customers on 3-year contracts reports ARR directly from ACV, not MRR * 12, because monthly Stripe charges do not reflect the contracted value.
A team sees ARR grow 50% YoY but NRR stuck at 95%. The growth is entirely new logos, and the existing base is silently eroding.
Common mistakes
- Reporting ARR without specifying whether it includes or excludes trials, discounts, or one-time fees.
- Using MRR*12 for enterprise contracts that bill annually and have significant proration.
- Treating ARR growth as the only KPI while ignoring NRR and gross churn.
- Double-counting multi-year deals by booking the full TCV as "ARR".
