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.
