ARR (Annual Recurring Revenue)

What is ARR?

Annual Recurring Revenue (ARR) is the annualized value of a subscription business's recurring revenue. It is calculated by multiplying MRR by 12, or by summing the annual value of all active subscription contracts.

ARR is the primary metric used by investors, boards, and leadership teams to evaluate the scale and growth trajectory of a subscription business. While MRR provides a monthly operating view, ARR is the benchmark for fundraising, valuation, and strategic planning.

ARR and the impact of payment failures

A 5% monthly involuntary churn rate due to failed payments compounds dramatically at the annual level. If you lose 5% of subscribers each month to unrecovered payment failures, you are losing far more than 5% of ARR annually — the compounding effect means the revenue gap widens every billing cycle.

This makes payment recovery one of the highest-leverage activities for protecting and growing ARR. Every dollar recovered from a failed payment contributes directly to the annualized figure that drives company valuation.

ARR vs. MRR: when to use which

MRR is better for operational decisions: monitoring month-over-month trends, evaluating campaign effectiveness, and managing cash flow. ARR is better for strategic decisions: setting annual targets, benchmarking against peers, and communicating with investors. Both should be tracked with involuntary churn broken out separately to identify recoverable revenue.
