Annual Recurring Revenue (ARR)

Annual Recurring Revenue, or ARR, is the annualized equivalent of MRR. The calculation is simple: ARR = MRR x 12. If a company has $500,000 in MRR, its ARR is $6 million. ARR provides a convenient way to express the scale of a subscription business in terms that are familiar to investors, analysts, and executives.

ARR is the preferred metric for enterprise SaaS companies with annual or multi-year contracts. While MRR makes more sense for businesses with predominantly monthly subscriptions, ARR better captures the committed revenue of annual deals. A company that signs a $120,000 annual contract records $120,000 in ARR immediately, even though it will be recognized as revenue over 12 months.

There is an important distinction between ARR and annual revenue. ARR is a forward-looking metric based on currently active subscriptions. Annual revenue is a backward-looking accounting measure that includes all recognized revenue, including one-time fees and professional services. ARR should only include revenue that is expected to recur.

ARR milestones are significant markers for SaaS companies. Crossing $1M ARR is often considered the first sign of product-market fit. $10M ARR is a common threshold for Series B funding. $100M ARR puts a company in "unicorn" territory depending on growth rate and efficiency. Investors use ARR growth rate, along with net revenue retention, as the primary valuation drivers.

Every dollar of ARR lost to involuntary churn represents twelve dollars of annual revenue that could have been retained. With LostChurn's payment recovery, businesses protect their ARR by ensuring that failed payments do not silently erode their revenue base.
