ARR is the annualized value of a company’s recurring subscription revenue, the predictable amount it expects to collect each year from active contracts. It is the headline metric for how a subscription software business is measured and valued.
ARR is the annual value of a software company’s recurring revenue: the subscription fees under contract, expressed as a yearly figure. A vendor with 1,000 customers each paying $12,000 a year represents $12 million in ARR. It counts recurring subscriptions and leaves out one-time fees such as setup or professional services .
How the number is built
ARR sums active recurring contracts and normalizes them to a year, so a monthly plan is multiplied out and a multi-year deal is divided down. Investors read it as the clearest signal of a subscription business’s scale and momentum, which is why growth-stage software companies report it ahead of almost anything else. Net revenue retention , the same base adjusted for expansions and cancellations, is its companion metric.
Why it shapes vendor behavior
For a martech buyer, ARR is worth understanding because it explains the other side of the table. Predictable recurring revenue is what the market rewards, so vendors work to protect it: they favor multi-year lock-in, resist pricing tied to outcomes they cannot guarantee, and treat the renewal as the moment the relationship gets defended. When a vendor pushes back hard on a usage or outcome model, ARR is usually the reason. Knowing that turns a vague negotiation into a specific one.
