ARR (Annual Recurring Revenue)
The annualized value of a company's recurring subscription or contract revenue — the primary metric for SaaS and subscription business valuation. ARR = Monthly Recurring Revenue × 12. ARR excludes one-time fees, professional services, and variable revenue. For subscription businesses, ARR is more reliable than EBITDA as a valuation anchor because it measures contracted future revenue. Related metrics: Net Revenue Retention (NRR) — measures ARR growth from existing customers; Gross Revenue Retention (GRR) — measures how much ARR is retained excluding expansions.
Full Definition
Annual Recurring Revenue (ARR) is the annualized value of a company's subscription-based or recurring contract revenue, calculated by multiplying current monthly recurring revenue (MRR) by 12. ARR represents the predictable, contractually committed revenue that will recur in the next 12 months if no customers are added or lost — making it the core valuation metric for SaaS and subscription businesses.
What counts as ARR: Truly recurring, contractually committed revenue qualifies — annual or multi-year subscription contracts, recurring SaaS license fees, and managed service agreements with committed minimums. One-time fees, professional services, implementation charges, and variable usage revenue above a contractual base generally do not count as ARR. The discipline of what's included matters: companies that stuff ARR with non-recurring revenue overstate their metric and eventually face painful corrections when those revenues don't renew.
ARR in M&A valuation: SaaS and subscription businesses are valued as a multiple of ARR rather than EBITDA when they're growing rapidly and investing heavily in growth. ARR multiples vary dramatically by growth rate, net revenue retention, churn, and gross margin. At peak valuations (2020–2021), high-growth SaaS companies transacted at 20–40x ARR. More normalized markets see 5–15x ARR for strong performers and 2–5x for slower-growing businesses. At lower growth rates (under 20% YoY) and positive EBITDA, buyers often switch to EBITDA multiples — the "Rule of 40" being the transition threshold.
ARR quality matters as much as ARR quantity: High-quality ARR comes from many customers (low concentration), sticky product usage, expanding accounts (net revenue retention > 100%), and multi-year contracts. Poor-quality ARR is concentrated in a few customers, declining in usage, and at risk of churn. Buyers pay for ARR quality — expect detailed diligence on customer concentration, cohort retention, and renewal rates.
Contracted vs. recognized ARR: ARR is a forward-looking metric, not an accounting one. It's the annualized value of current active contracts, regardless of when revenue is recognized under ASC 606. Understand whether a company's reported ARR includes contracts signed but not yet live, and whether it nets out known churned customers.
Seller vs. Buyer Perspective
Your ARR figure will be stress-tested in diligence. Buyers will ask for a customer-by-customer ARR schedule, renewal dates, churn history, and expansion revenue. Be precise about what you include: mixing in services revenue or one-time fees that you've labeled as recurring will be unwound in diligence and damage credibility. Present ARR conservatively and let the quality speak for itself — buyers pay significant premiums for high net revenue retention and low churn, both of which you can demonstrate with cohort data.
ARR is a starting point, not the answer. The questions that determine what multiple you should pay: What is gross revenue retention (what % of last year's ARR renewed)? What is net revenue retention (does the cohort expand)? What is customer concentration (does one customer represent more than 10% of ARR)? How long are the contracts (monthly, annual, multi-year)? What is the gross margin on ARR (high-gross-margin ARR is worth more than low-margin ARR)? Get the full ARR waterfall — new, expansion, contraction, churn — for at least 3 years before committing to a valuation.
Real-World Example
A B2B SaaS company with 85 customers has $2.4M in ARR growing at 35% YoY, with net revenue retention of 118% and no single customer over 7% of ARR. A strategic acquirer pays 9x ARR ($21.6M) — a premium multiple justified by the growth rate, diversified customer base, and expanding existing accounts, all of which reduce the risk that ARR will deteriorate post-acquisition.
Why It Matters & Common Pitfalls
- !ARR and revenue are not the same. GAAP revenue is recognized over time as the service is delivered; ARR is a point-in-time metric of contracted future revenue. A company that just signed a large annual contract has high ARR but may have low revenue recognized to date. Make sure financial statements and ARR figures are reconciled.
- !Churn is the silent ARR destroyer. A company growing gross ARR at 20% but churning 25% annually is actually shrinking. Always look at gross ARR growth alongside gross churn to understand whether the business is genuinely growing or just running in place on a treadmill.
- !Multi-year contracts can flatter ARR. A large multi-year deal inflates ARR in year one. If that customer doesn't renew in year three, the ARR cliff is dramatic. Understand the renewal schedule and when large contracts are up.
- !Services attached to SaaS inflate perceived ARR. Implementation, training, and professional services revenue bundled with software contracts may be presented as recurring — it often isn't. Unbundle the components in diligence and value them separately.

Revenue Multiple
A valuation expressed as a multiple of annual revenue rather than EBITDA — most common in SaaS and high-growth tech-enabled businesses where EBITDA may be minimal or negative during growth phases. Revenue multiples vary enormously by business quality: SaaS businesses with strong ARR, high net revenue retention, and clear growth might trade at 4-8x+ ARR; traditional services businesses rarely use revenue multiples. For SMB businesses with normal profitability, EBITDA multiples are far more common and appropriate.
Valuation Multiple
The ratio between enterprise value and a financial metric — typically EBITDA — used to express what a business is worth in comparable terms. The primary language of SMB/LMM M&A pricing.
MRR (Monthly Recurring Revenue)
The monthly value of a company's recurring subscription or contract revenue — the building block for ARR (ARR = MRR × 12). MRR is tracked as a real-time performance indicator: new MRR (from new customers), expansion MRR (from upgrades), churned MRR (from cancellations), and contraction MRR (from downgrades). Net new MRR is the period's change in total MRR. For SaaS and subscription businesses, MRR trends are the primary operational signal reviewed in monthly board meetings.
