Annual Recurring Revenue (ARR)
Updated July 21, 2026
MRR multiplied by 12, used for year-over-year comparisons and company valuation.
Also known as: Annual Recurring Revenue, ARR, Annualized Recurring Revenue
Annual Recurring Revenue (ARR) is the value of a SaaS company's committed, contracted, recurring subscription revenue normalized to a single year. The most common calculation is simply monthly recurring revenue times twelve, though finance teams often build it up from components instead: new ARR plus renewal ARR plus expansion ARR, minus churned and contraction ARR. Either way, ARR counts only the recurring portion of a subscription. One-time sales, setup and onboarding fees, and professional services are excluded by standard definitions, because the point of the metric is to isolate the durable, repeatable revenue base that a company can expect to persist year over year.
ARR is the number boards and investors reach for when they compare growth across years and when they value a B2B SaaS business. It smooths out the monthly noise that MRR carries and expresses the business at an annual scale that maps cleanly to contract terms, revenue targets, and valuation multiples. That is why it is especially natural for companies selling annual or multi-year contracts, where a customer's commitment is already denominated in years.
The term has no single credited inventor. It emerged as a de facto convention among early enterprise SaaS companies that sold on annual contracts, where an annualized recurring figure was the obvious reporting unit. As later SaaS companies moved toward monthly billing, the ARR label persisted even where the underlying billing cadence had changed, which is part of why the term is now sometimes applied loosely.
How ARR is calculated
The quick version is ARR equals MRR multiplied by twelve. If a company books 200,000 dollars of monthly recurring revenue, its ARR is 2.4 million dollars. This works because MRR already excludes non-recurring charges, so annualizing it preserves that discipline.
Finance teams that want more precision build ARR from its moving parts instead. Gross new ARR from new logos, plus renewal ARR from existing customers, plus expansion ARR from upsells and seat growth, minus churned ARR from cancellations and minus contraction ARR from downgrades. Netting the additions against the losses produces net ARR, which reflects real growth rather than gross bookings.
The exclusions matter as much as the formula. Committed, contracted recurring subscription fees count. Implementation fees, one-time training, and professional services do not, because they are not repeatable. Mixing them in inflates the figure and breaks year-over-year comparability, which is exactly what ARR exists to protect.
ARR vs. MRR
ARR and MRR measure the same underlying thing at different time scales. MRR is the monthly recurring-revenue figure; ARR is that figure normalized to a year, most often as MRR times twelve. The choice between them is mostly a question of billing cadence and reporting audience.
MRR tends to be the working metric for companies with monthly billing, product-led motions, or frequent month-to-month expansion and churn, because it captures those movements as they happen. ARR tends to be the board-and-investor metric for companies selling annual or multi-year contracts, where an annualized number matches the commitment structure and reads more cleanly against valuation multiples. Neither is more correct. A business can track both, using MRR to watch operational momentum and ARR to frame growth and valuation, and the two should always reconcile through the times-twelve relationship.
ARR vs. Annualized Run Rate and other look-alikes
The acronym ARR is overloaded, and the confusion is consequential. Annual Recurring Revenue is committed, contracted, recurring subscription revenue. Annualized Run Rate is a different metric that extrapolates a single month's or quarter's revenue out to a full year, and it sometimes sweeps in non-recurring revenue. Presenting a run-rate figure as if it were contracted ARR is treated as a due-diligence red flag, because it can imply durability the contracts do not support.
ARR also sits alongside several adjacent measures. ACV, Annual Contract Value, is the annualized value of a single customer's contract, where ARR is the aggregate across the whole base. TCV, Total Contract Value, is a contract's full value over its entire term including non-recurring components. CARR, Committed or Contracted ARR, includes signed contracts that have not yet started billing, giving a forward-looking number that overstates live ARR unless it is labeled clearly.
How competitive intelligence teams use ARR
For a private competitor, exact ARR is rarely public, so CI work assembles an estimate and, more usefully, tracks its direction. Funding announcements, press releases, and the occasional disclosed milestone give anchor points; the recurring job is watching the signals that move the number between those points.
Hiring is one such signal. A surge in sales and implementation roles usually precedes bookings growth, while quiet or shrinking headcount can foreshadow a plateau. Pricing-page changes, new plan tiers, and packaging shifts change the ARR contribution of every future deal. Public churn signals, review-site sentiment, and customer announcements hint at whether the recurring base is expanding or leaking. Teams that monitor competitor websites, pricing pages, job postings, and news continuously can maintain a running estimate of a rival's ARR trajectory and revise it on evidence, rather than waiting for the next funding round to reset their assumptions.
Common mistakes and limitations
The most common error is contaminating ARR with revenue that is not recurring: counting setup fees, professional services, or one-time upgrades inflates the figure and makes year-over-year growth look better than the subscription base warrants. A close cousin is reporting gross ARR movement while ignoring churned and contraction ARR, which overstates real growth by hiding the leaks.
Mislabeling is the other recurring problem. Reporting CARR as ARR pulls not-yet-live contracts into a live figure, and reporting an annualized run rate as ARR extrapolates a short window into a claim of durability. Both are why careful readers ask exactly how a stated ARR was built.
ARR is also only a top-line durability measure. It says nothing about gross margin, acquisition cost, or retention quality on its own, which is why it is read next to metrics like NRR, LTV, and CAC rather than in isolation.

Frequently Asked Questions
What is ARR in SaaS?
ARR, Annual Recurring Revenue, is the yearly value of a company's committed, contracted, recurring subscription revenue. It counts only revenue that repeats, so one-time fees, setup charges, and professional services are left out. Because it normalizes the subscription base to a full year, it is the metric boards and investors use to compare growth across years and to value B2B SaaS businesses.
How do you calculate ARR?
The simplest method is monthly recurring revenue multiplied by twelve. For more precision, finance teams sum new ARR, renewal ARR, and expansion ARR, then subtract churned and contraction ARR to get net ARR. Both approaches exclude non-recurring revenue such as implementation and professional-services fees, since ARR is meant to capture only durable, repeatable subscription revenue.
Is ARR the same as Annualized Run Rate?
No, even though both are abbreviated ARR. Annual Recurring Revenue is committed, contracted recurring subscription revenue. Annualized Run Rate extrapolates one month's or quarter's revenue out to a year, and can include non-recurring revenue. Reporting a run-rate number as if it were contracted ARR is considered a due-diligence red flag, because it implies a durability the underlying contracts may not actually support.
Does ARR include one-time fees or professional services?
No. By standard definition, ARR includes only committed, recurring subscription fees. One-time sales, setup and onboarding charges, and professional services are excluded because they do not repeat predictably. Including them inflates the figure and undermines the year-over-year comparability that ARR exists to provide, which is why careful readers ask how a stated ARR number was constructed.
What is the difference between ARR and ACV?
ACV, or Annual Contract Value, measures the annualized worth of one customer's contract, whereas ARR aggregates recurring revenue across the whole customer base. Put simply, ACV describes one deal and ARR describes the whole book. Both are annualized and both focus on recurring value, but they answer different questions: per-customer economics versus total company scale.
