Annual recurring revenue (ARR) is the normalized yearly value of recurring subscription or contract revenue. It answers a practical startup question: how much revenue should repeat over the next year? section 13.3.1
ARR matters because it makes a SaaS business easier to understand:
- Customers can adjust spending by adding or canceling seats, changing operating expenses quickly. section 13.3.1
- Investors value revenue that repeats and grows while the company tests and improves product-market fit. section 13.3.1
The useful mental model
Think of a company selling SaaS seats to large corporations. The subscriptions produce ARR, while customers can reduce their seat count if budgets tighten. The attraction is not merely making a sale; it is building a revenue stream that can repeat year after year. section 13.3.1
