Annual Recurring Revenue (ARR)

What Is Annual Recurring Revenue?

Annual Recurring Revenue is the run-rate of every active subscription. One-time fees, services, and pure overages don't count. The "active" qualifier matters too: a contract that ended last week is not ARR even if the cash hit the bank yesterday, and a three-year prepay counts at one-third its total value, not the full check.

ARR is the metric VCs underwrite, boards report, and CEOs go on stage to say. A $40M ARR Series B at a 15x multiple is a $600M valuation. A $40M bookings number at the same multiple is, depending on the mix, somewhere between $200M and $700M — which is why the line between ARR and bookings is policed by every CFO with a working calculator.

How Annual Recurring Revenue Is Calculated

The formula is straightforward and the policy decisions around it are not.

ARR = Σ (committed annualized recurring contract value) for all active subscriptions

A $360K three-year contract = $120K of new ARR. A $50K annual license + $20K of onboarding = $50K ARR. A $200K usage commit with $80K of unbilled overage = $200K ARR. The unbilled overage is great for cash but it isn't recurring by contract.

Worked ARR Example

A vertical SaaS company has 142 active customers. 90 are on annual plans averaging $14K — that's $1.26M ARR. 40 are on three-year plans totaling $4.8M in TCV — that's $1.6M ARR. 12 are on month-to-month at $1,200/mo — that's $172.8K ARR. Total ARR: $3.03M. Bookings last quarter were $1.4M, but most of that was multi-year prepay; net new ARR added that quarter was $310K. Those two numbers describe completely different businesses to an investor.

When Sales and Finance Teams Use ARR

CFOs use ARR for SaaS valuation, the Rule of 40, and burn-multiple math. CROs use ARR growth rate, year-over-year, as the primary scoreboard. RevOps uses Net Revenue Retention and Gross Revenue Retention — both ARR-denominated — to diagnose the install base. Sales reps usually carry a bookings quota or net new ARR quota, not total ARR; the difference matters at comp time. Boards demand monthly ARR snapshots with movement detail: new, expansion, contraction, churn.

Common ARR Gaming Patterns

ARR is the most-manipulated number in SaaS, and four exploits show up repeatedly in audits and reforecasts. First: stuffing services revenue into the ARR line by calling a $200K implementation an "annual platform fee." Second: counting pilots and POCs that historically convert at 30% as if they were committed ARR. Third: booking the full TCV of a multi-year deal as ARR — a $900K three-year contract is $300K ARR, not $900K, and that exact distinction has ended IPO roadshows. Fourth: refusing to net out churn in real time, so a customer who gave 90 days notice last month still shows in the ARR snapshot the CEO presents to the board. Investors learned all four of these the hard way between 2015 and 2022, which is why diligence now reconciles ARR back to billings, the GL, and the active-subscription list line by line.
