Annual Recurring Revenue

A key metric for subscription businesses that projects the annualized value of all active recurring contracts.

Annual Recurring Revenue (ARR) is a key performance indicator used by subscription-based businesses, particularly Software-as-a-Service (SaaS) companies, to measure the predictable and recurring portion of their revenue stream. It normalizes contract values over a one-year period, excluding one-time setup fees, professional services, and variable usage charges. By focusing strictly on recurring contract values, ARR provides a highly reliable baseline of a company's predictable top-line performance. To calculate ARR, companies aggregate the annualized value of all active subscription contracts. For contracts billed monthly, the Monthly Recurring Revenue (MRR) is multiplied by 12. For multi-year contracts, the total contract value is divided by the contract term in years. Investors monitor this metric closely because it serves as a leading indicator of future cash flow and revenue visibility, which are critical components of valuation models. Investors value high ARR because it indicates a highly scalable business model with strong customer retention. However, when evaluating ARR, investors must also monitor customer churn and customer acquisition costs. If a company is adding new ARR but losing existing customers at a high rate, the growth is unsustainable and expensive to maintain. Additionally, relying solely on ARR without looking at actual cash collections can mask working capital issues if customers are slow to pay.

A software company has 1,000 customers paying a monthly subscription fee of $100, and 50 enterprise customers on annual contracts worth $12,000 each. The monthly subscriptions generate $1.2 million annually ($100 12 1,000), and the enterprise contracts generate $600,000 annually, resulting in a total ARR of $1.8 million ($1,200,000 + $600,000).
