What is ARR (Annual Recurring Revenue)?

Why It Matters

ARR is the number investors, boards, and most SaaS companies use to talk about scale and growth, precisely because it normalizes revenue from monthly, annual, and multi-year contracts onto the same one-year basis, making otherwise incomparable businesses comparable. Because it's derived directly from MRR, any distortion in how MRR is calculated, like miscounting a multi-year deal's true annualized value, flows straight through into a misleading ARR figure. Tracking ARR growth over time is also what most SaaS growth benchmarks, valuation multiples, and board reporting are built around, so getting the underlying calculation wrong has consequences well beyond a single dashboard number. It's the anchor metric that net revenue retention, expansion revenue, and other growth metrics are all measured against.

Example

A company with $90,000 in monthly recurring revenue has an ARR of $90,000 times 12, which equals $1,080,000. If that same company signs a new customer to a 2-year contract worth $24,000 total, the deal still only adds $12,000 to ARR, the annualized value of the contract, not the full $24,000 collected over its lifetime. This normalization is what makes ARR comparable across companies with very different contract lengths and billing cycles, which is why investors and boards use it as the standard yardstick for SaaS growth rather than raw contracted revenue.

Frequently Asked Questions

• Does ARR include one-time revenue like setup fees?

  No, ARR is meant to capture only recurring, repeatable revenue. One-time fees such as implementation or setup charges are typically excluded since they don't recur the following year.

• How is ARR different from total bookings or contract value?

  Bookings and total contract value reflect the full value of a signed deal over its entire term, while ARR only reflects the annualized recurring portion, which is why a 2-year, $24,000 contract adds $12,000 to ARR, not $24,000.

• Why do SaaS companies prefer ARR over MRR for reporting?

  ARR is simply MRR scaled to an annual view, which tends to be the more intuitive and commonly cited figure for investors, boards, and year-over-year growth comparisons, even though the two are mathematically the same underlying number.

• What causes ARR to grow or shrink beyond new sales?

  Expansion revenue from existing customers upgrading, contraction from downgrades, and churn from cancellations all move ARR alongside new bookings, which is why net revenue retention is tracked separately to isolate the existing-customer effect.

• How often is ARR tracked?

  Most subscription businesses recalculate ARR monthly, since it's derived directly from the current MRR snapshot, and review the trend line quarterly or annually for board and investor reporting.
