ARR

Rogue ID: sales.arr Type: Currency Domain: Sales

Definition

Annual Recurring Revenue — the value of all recurring subscription revenue normalized to a one-year run-rate as of the period close. The headline operating metric for a subscription business; every growth and efficiency ratio (NRR, GRR, magic number, CAC payback, Rule of 40) is calibrated against it. Excludes one-time fees, professional services, and non-contractual usage. Common pitfall: confusing ARR (contracted recurring) with revenue (recognized) or with CARR (contracted incl. not-yet-live) — the SMSB standard draws sharp lines between them, and boards expect the same discipline. The KpiVarianceTable widget surfaces forecast / actual / variance / status / future-forecast columns against the same field.

Formula

ARR = Sum of annualized value of all active recurring subscription contracts at period close. Per SMSB: includes only the recurring portion of contracts that are live (delivered / in production). Excludes one-time fees, professional services, and usage that is not contractually committed. For multi-year contracts, ARR is the contract value divided by the term in years.

Why it matters

Headline operating number that every other SaaS metric calibrates against — growth rate, efficiency ratios (CAC ratio, magic number, Rule of 40), retention math (NRR, GRR), and valuation multiples all read off ARR. Boards use the period-over-period ARR delta as the first-pass health check for the business.

How to interpret

Per KBCM/Sapphire SaaS Survey 2024 §Growth Rate, public-SaaS-comparable private companies in the $5–25M ARR band typically grow ARR 40–60% YoY, falling toward 20–30% by $100M+ ARR; well-below-band growth at any ARR scale is the first thing a board interrogates. Always read ARR alongside Net New ARR (sales.new_business + sales.expansion − sales.churn_arr − sales.downgrades) — flat ARR can mask churn offset by upsell.

Calculation policy

How an AI agent should compute this KPI from messy company data. Free-text rules consumed at reasoning time — not a deterministic DSL. The most common ways to get this wrong are listed under Common miscomputations.

Inclusion rules

• Recurring revenue from contracts that are live / delivered / in production at the period close.
• Annualized value of multi-year contracts is the contract value divided by the term in years (not first-year ARR, not back-loaded).
• Contractually committed usage minimums count as recurring (the floor, not the expected overage).

Exclusion rules

• One-time fees: setup, implementation, onboarding, professional services, training — even when invoiced on a recurring cadence.
• Non-committed usage / overage revenue (only contractual minimums count).
• Signed contracts not yet live (those belong in CARR; promote to ARR on go-live).
• Recognized revenue, invoiced revenue, or bookings — ARR is contracted-recurring run-rate, not any of those.

Required inputs

• Contract status (live / signed-not-live / churned).
• Contract value (annualized, multi-year divided by term).
• Contract start date and term length (months or years).
• Recurring-vs-one-time flag per line item (or per contract if line items are not modeled).

Data-source priority

• CRM contract / subscription system with explicit go-live status (Salesforce, HubSpot Subscription Module, Zuora, Chargebee).
• Billing system as a fallback when contract status is not modeled — but verify against the contract data, since billing can run ahead of go-live.
• Spreadsheet exports: only when nothing else exists; flag uncertainty in the output.

Edge cases

• Partial-month or mid-period starts: prorate or use end-of-period contract value, but be consistent across the time series.
• Contract amendments (price changes, term extensions): re-annualize from the amendment date; do not back-fill prior periods.
• Pauses / suspensions: treat as churn unless contract is held open with go-live SLA — flag the ambiguity in any output.
• Multi-currency: normalize to a single reporting currency at a stable FX rate (period-end or a documented fixed rate); never mix.
• Ramp contracts (escalating annual fees): use the contractually committed annual value for the period, not the average over the ramp.

Validation checks

• Ending ARR ≈ Starting ARR + New Business + Expansion − Downgrades − Churn ARR — if the waterfall does not reconcile to within 1%, the underlying components are misclassified.
• ARR ≤ total contracted value across all live contracts.
• Year-over-year growth rate sits within the KBCM/Sapphire band for the ARR scale; out-of-band growth in either direction is a calculation red flag, not a story.

Common miscomputations

• ARR-vs-CARR confusion: including signed-but-not-yet-live contracts inflates ARR and contradicts the SMSB definition. If unsure, report both ARR and CARR separately and let the reader pick.
• Recognized revenue × 12 or × 4: this is run-rate revenue, not ARR. The two diverge when service revenue is recognized at a different cadence than subscription value.
• MRR × 12 only matches ARR when MRR itself is calculated from contracted recurring (not from invoiced or recognized revenue) — verify upstream.
• Counting expansion or renewal ARR in the "new business" line — inflates the acquisition motion and hides a stalled new-logo engine.
• Mixing fiscal-year-end ARR and period-end ARR in the same chart: always pin to one snapshot definition per series.
