Annual Recurring Revenue
Also: ARR
Definition. Under the same recurring-revenue policy, ARR = 12 × MRR is an annualized snapshot of the current monthly run rate. It is distinct from recognized revenue, signed bookings, invoices and cash collections. Variable usage requires a disclosed normalization policy.
Formula
Annual Recurring Revenue identity
Plain English: ARR = MRR × 12
Notation: ARR_t = MRR_t × 12 = 12 × Σ(p_i / billing_months_i)
Benchmark by stage
Source: Definition and annualization convention. Stage bands are illustrative scale ranges, not current financing or IPO requirements.
| Stage | Annual Recurring Revenue | Notes |
|---|---|---|
| Seed | $0–$600k ARR | Illustrative scale band; financing and investment decisions require company-specific economics. |
| Series A | $1M–$5M ARR | Illustrative scale band; financing and investment decisions require company-specific economics. |
| Series B | $5M–$25M ARR | Illustrative scale band; financing and investment decisions require company-specific economics. |
| Series C | $25M–$100M ARR | Illustrative scale band; financing and investment decisions require company-specific economics. |
| Pre-IPO / Public | $100M+ ARR | Illustrative scale band; financing and investment decisions require company-specific economics. |
Naive vs corrected
| Version | Formula |
|---|---|
| Naive | Treating recognized revenue, signed total contract value or cash collected as the active recurring annual run rate. |
| Corrected | ARR = 12 × consistently defined MRR. State treatment of future starts, variable usage, currency, services and recurring discounts. |
Common errors
- Conflating trailing recognized revenue with current annualized run rate
- Including one-time services without disclosure
- Counting multi-year total contract value as one year of ARR
- Changing recurring-revenue or currency policy between comparison periods
- Confusing annual contract value, total contract value and recurring run rate
Where this sits
Part of the Economics & metrics (C4) cluster in the GTM World Model. Related to the model's "ARR growth rate = (ARR_t - ARR_{t-12}) / ARR_{t-12}; used in Rule of 40 and Rule of X calculations" equation.
