ARR (Annual Recurring Revenue)

What is annual recurring revenue (ARR)?

Annual recurring revenue (also written as ARR, or sometimes annualized recurring revenue) is the annualized value of all active recurring subscription contracts. If a customer pays $1,000/month on a subscription, that customer contributes $12,000 to ARR. It's the simplest and most important metric in SaaS.

ARR matters because it represents the predictable revenue base a company can count on if nothing changes — no new customers, no churn, no expansion. It's the baseline. Every SaaS financial model, valuation, and board deck starts with ARR and builds from there.

For B2B SaaS companies, ARR multiples drive valuations. At the median, public SaaS companies trade at 6–10x ARR (Bessemer Cloud Index, 2025). High-growth companies with strong net revenue retention trade at 15–25x. The growth rate of ARR — not the absolute number — is what investors and acquirers evaluate.

ARR is sometimes confused with total revenue or MRR. Total revenue includes one-time fees, services, and variable charges. MRR is the monthly equivalent of ARR. ARR = MRR × 12, but only when MRR excludes non-recurring revenue.

Why ARR matters for operators

ARR is the single metric that determines how a SaaS company is valued, funded, and strategically managed. Every decision — hiring, channel investment, product roadmap — traces back to ARR impact.

Without accurate ARR tracking, operators can't answer basic questions: Are we growing? How fast? Is growth accelerating or decelerating? A company showing $500K in monthly revenue might have $4.5M ARR (mostly recurring) or $6M in total revenue with only $3M recurring. The operating implications are completely different.

A typical 60-person SaaS company crossing $5M ARR faces a specific challenge: ARR components start diverging. New business ARR, expansion revenue, and churned ARR need to be tracked separately. If you only track the top-line number, you can't tell whether growth is coming from new logos or expansion — and the two require very different go-to-market strategies.

ARR formula

What to include in ARR:

ARR = MRR × 12

Where MRR = Sum of all active monthly recurring subscription values

Example:
- 150 customers paying an average of $2,800/month
- MRR = 150 × $2,800 = $420,000
- ARR = $420,000 × 12 = $5,040,000

For annual contracts:
ARR = Sum of all active annual contract values

• Monthly subscription fees (annualized)
• Annual subscription fees
• Committed platform/seat fees

What to exclude from ARR

• One-time setup or implementation fees
• Professional services revenue
• Variable usage charges above the base subscription
• Overdue invoices past 90 days (some companies exclude at 60 days)

Common mistakes when tracking ARR

1. Including non-recurring revenue in the ARR number. Professional services, one-time implementation fees, and variable usage charges are not ARR. Including them inflates the number and misleads investors, board members, and your own strategic planning. Strip them out.

2. Not separating ARR into components. Total ARR is useful. Decomposed ARR is actionable. Track four components separately: new business ARR, expansion ARR, contraction ARR, and churned ARR. Without this breakdown, you can't diagnose whether growth is healthy or masking churn.

3. Counting pipeline as ARR. Committed deals that haven't closed are pipeline, not ARR. ARR only includes signed, active contracts. The temptation to include "verbal commits" inflates the number and creates false confidence in forecasts.

4. Ignoring ARR per employee as an efficiency signal. ARR per employee is the fastest way to spot scaling inefficiency. If ARR is growing at 50% but headcount is growing at 70%, the company is getting less efficient. Track both.

5. Annualizing a single month's MRR during seasonal variation. If January MRR is $420K, ARR is not necessarily $5.04M. If the business has seasonal patterns, use a trailing 3-month average MRR for the annualization. One-month snapshots can mislead.

How Fairview tracks ARR automatically

Fairview's Operating Dashboard pulls subscription data from your CRM (HubSpot, Salesforce) and payment processor (Stripe) to calculate ARR in real time — decomposed into new, expansion, contraction, and churned components.

Instead of building a monthly ARR waterfall in a spreadsheet, you see the breakdown automatically. The Forecast Confidence Engine uses ARR trends and pipeline coverage to project next-quarter ARR with a confidence score — so you know not just the forecast, but how much to trust it.

ARR vs MRR

ARR and MRR measure the same underlying revenue — just on different time horizons. Use MRR for operational decisions (month-to-month trends). Use ARR for strategic decisions (valuations, hiring plans, annual budgets).
