Summarize this article

The ARR slide says $10M. The income statement says $8.2M. Which one is right? Actually, both are correct, and that's the problem.

‍

These two numbers measure two different things, and they're commonly confused by SaaS founders who are new to the game. Unfortunately, mixing them up can cause due-diligence problems and uncomfortable questions from investors.

‍

This guide explains why ARR vs revenue look different, featuring a walkthrough of a real-world reconciliation example -- so you can see how the same company reports both numbers — and a look at the scenarios where ARR can be higher or lower than recurring revenue under GAAP. We're also including an ARR bridge format you can copy into your next board deck, a CARR comparison, and the calculation mistakes that mislead investors most often.

TL;DR

What is ARR? The annualized value of all active recurring subscriptions at a point in time. Forward-looking, non-GAAP, and excludes everything one-time: professional services, onboarding fees, and uncommitted usage overages.
What is GAAP revenue? The amount recognized on the income statement under ASC 606 for a specific period. Backward-looking, includes professional services and one-time fees, and reflects actual delivery — not contract value.
Why do they differ? Mid-year contracts add full value to ARR immediately but only recognized months count toward revenue. Churned customers drop out of ARR instantly but keep generating revenue until service ends. Pro services and one-time fees appear in GAAP revenue but never in ARR.
What is an ARR bridge? The board-level format that shows how ARR moved in a period: beginning ARR + new + expansion – churn – contraction = ending ARR. Net new ARR and NRR both fall out of the same calculation.
What is CARR? Committed ARR — includes signed contracts not yet live. Always ≥ ARR. Matters most in enterprise SaaS with long implementation timelines; less relevant for self-serve products where contracts activate instantly.
The most common mistakes? Including professional services in ARR, annualizing a single strong month, leaving churned customers in the count, and counting multi-year deals at total contract value instead of the annual rate.

What is ARR?

Annual recurring revenue (ARR) is the annualized value of a company's active subscription contracts at a point in time. It includes only recurring subscription fees and excludes one-time charges, professional services, and usage overages. ARR is an operating metric, not a GAAP measure,^[⁴^] and represents the forward-looking revenue run rate.

The ARR formula

The basic formula is straightforward:

ARR = MRR * 12

Or the sum of all active annual subscription contract values. A customer on a $10K/month plan contributes $120K of ARR.

‍

What's included is recurring subscription fees only: monthly subscriptions annualized, annual subscriptions at contract value, and multi-year subscriptions valued at the current year's annual rate.

‍

What's excluded is everything non-recurring. Think implementation fees, professional services, training, usage overages without a committed minimum, hardware, and physical goods.

‍

The most important thing to understand about ARR is that it's a point-in-time snapshot. It tells you what the company would earn over the next 12 months if nothing changed (no new sales, churn, or expansions). It's a forward-looking metric that investors lean on for evaluating growth.

What is GAAP revenue?

GAAP revenue is the amount recognized on the income statement under ASC 606 ^[¹^] after performance obligations are satisfied. Unlike ARR, it includes professional services and one-time fees, reflects actual delivery (not contract value), and it's a backward-looking measure of revenue already earned during a specific period.

Revenue recognition under ASC 606

ASC 606 establishes a five-step model ^[¹^] for recognizing revenue:

‍

Identify the contract
Identify the performance obligations in the contract
Determine the transaction price
Allocate the transaction price to the performance obligations
Recognize revenue when (or as) each obligation is satisfied

‍

For subscriptions, revenue is recognized ratably over the service period.^[¹^] In SaaS accounting, subscription revenue spreads month by month. Professional services are recognized on delivery (or at milestones),^[1] usage charges are recognized with consumption,^[¹^] and one-time setup fees are typically recognized over the contract term unless they represent a distinct performance obligation.^[¹^]

‍

The timing difference is what creates the gap with ARR. For example: a $120K annual contract signed on July 1st contributes $120K to ARR immediately, but only $60K to GAAP revenue in that calendar year. The remaining $60K rolls into next year.

‍

TL;DR: Revenue answers "how much did we earn last quarter?", and ARR answers "what's our current run rate?"

ARR vs revenue: a side-by-side comparison

	ARR	GAAP Revenue
Definition	Annualized value of active recurring subscriptions	Revenue recognized per ASC 606^[1] in a period
Type of metric	Operating / SaaS metric (non-GAAP)^[4]	Accounting standard (GAAP)
Time frame	Point-in-time snapshot (forward-looking)	Period measure (backward-looking)
Includes one-time fees?	No	Yes
Includes pro services?	No	Yes
Includes usage overages?	Only if committed minimum	Yes, as consumed
Recognition timing	Full contract value on signing/renewal	Ratably over service delivery period^[1]
Churned customers	Removed immediately from ARR	Revenue recognized until service period ends
Reported where?	Board deck, investor materials, SaaS metrics	Income statement (10-K, 10-Q)
Primary audience	Investors, board, management	Auditors, SEC, lenders, tax authorities
Regulated?	No (no standard definition)	Yes (ASC 606^[1] / IFRS 15^[2])

When ARR and revenue differ

ARR and GAAP revenue diverge because ARR is a point-in-time annualization of active contracts, while revenue is recognized ratably over the service period.^[¹^] In the example below, a company finishing the year with $9.7M in ending ARR reports $9.975M in full-year GAAP revenue — higher than ARR — because non-recurring revenue streams such as professional services, onboarding fees, and usage overages are included in GAAP but excluded from ARR.

Real-life example: $9.7M ending ARR vs. $9.975M full-year GAAP revenue

Scenario	ARR Impact	GAAP Revenue Impact
100 customers on $80K annual plans (full year)	$8,000K	$8,000K
20 new customers signed Jul 1 on $100K annual plans	$2,000K (full value)	$1,000K (6 months recognized)
5 customers churned Sep 30 (were on $60K plans)	–$300K (removed)	$225K (9 months recognized)
Professional services delivered	$0 (excluded)	$400K (recognized on delivery)
One-time onboarding fees	$0 (excluded)	$200K (recognized over contract)
Usage overages (not committed)	$0 (excluded)	$150K (recognized as consumed)
Ending ARR (Dec 31)	$9,700K	—
Full-year GAAP revenue	—	$9,975K

‍

To break down the main differences here...

‍

Mid-year contracts create the biggest gap. The 20 new customers signed July 1 added the full $2M to ARR the moment they signed — but ASC 606 ^[¹^] only allows you to recognize the months of service actually delivered. 6 months in, that's $1M of GAAP revenue. The other $1M stays in deferred revenue and is recognized next year.
Churned customers are removed from ARR instantly but keep generating GAAP revenue. The 5 customers who churned on September 30 came out of ARR the same day. However, they still contribute GAAP revenue for the months they were active.
Professional services and one-time fees boost GAAP revenue, but don't appear in ARR. Pro services ($400K), onboarding fees ($200K), and uncommitted usage overages ($150K) are all recognized through the income statement, but they're excluded from ARR.

‍

In this example, GAAP revenue actually comes in higher than ending ARR because of the non-recurring revenue streams.

The ARR bridge (and how to build it for your board)

ARR Bridge Component	Amount ($K)	Notes
Beginning ARR (Jan 1)	$8,000	Starting point from prior period
+ New ARR (new logos)	$2,400	30 new customers acquired
+ Expansion ARR (upsells, cross-sells)	$800	Upgrades + seat additions
– Churned ARR (lost customers)	($900)	15 customers churned
– Contraction ARR (downgrades)	($400)	Seat reductions + plan downgrades
= Ending ARR (Dec 31)	$9,900	23.75% YoY growth
Net New ARR	$1,900	New + Expansion – Churn – Contraction

‍

Every credible SaaS board deck includes an ARR bridge, which shows how ARR moved from the start of the period to the end. Net new ARR is among the most closely watched metrics in SaaS fundraising.^[³^] It captures the company's ability to grow its recurring base after accounting for churn.

How to calculate NRR from the bridge?

Net Revenue Retention = (Beginning ARR + Expansion – Churn – Contraction) / Beginning ARR

In the example above: ($8,000 + $800 – $900 – $400) / $8,000 = 93.75%

A number below 100% means the existing customer base is shrinking.

Most boards review the ARR bridge quarterly. Fast-growing companies often run it monthly. The format doesn't change with the period — only the columns do.

CARR vs ARR vs revenue

Committed annual recurring revenue (CARR) includes signed contracts that haven't started generating revenue yet — like a deal closed in December that goes live in February. ARR only counts active, delivering contracts. CARR is always equal to or higher than ARR because it includes the pipeline of signed, but not yet live, subscriptions.

‍

	CARR	ARR	GAAP Revenue
Includes signed but not live?	Yes	No	No
Includes pro services?	No	No	Yes
Time orientation	Forward (includes pipeline)	Forward (current run rate)	Backward (earned)
When to use	Enterprise SaaS with long implementation cycles	Standard SaaS reporting	Financial statements, SEC filings
Typical relationship	CARR ≥ ARR	ARR ≠ Revenue	Depends on mix and timing

‍

CARR is most useful for enterprise SaaS companies, where time-to-live can be significant after a contract is signed. For self-serve or PLG SaaS, where contracts go live the moment the customer signs up, CARR and ARR are effectively the same number, so there's no point reporting both.

Common ARR calculation mistakes

Including professional services in ARR: ARR is recurring subscription revenue only. Combining it with implementation, onboarding, or training fees inflates the number and tells investors your revenue is higher quality than it actually is.
Annualizing a single strong month: If December was your best month ever, annualizing December's MRR overstates ARR. Use your actual active contract base instead.
Not removing churned contracts: A customer who gives 90-day notice in October should drop out of ARR when notice is given (or when service ends, depending on your policy). Leaving them in until the last day of service inflates the number, hiding churn.
Counting multi-year deals at total contract value: A 3-year $300K contract is $100K of ARR, not $300K.
Including usage overages in ARR: Variable usage charges aren't recurring unless the customer has a committed minimum.
Confusing bookings with ARR: Bookings represent total contract value. ARR represents the annualized recurring portion. The two aren't interchangeable.

Tracking ARR and revenue together in DualEntry

Many SaaS companies between $5M and $50M ARR are managing reconciliation in spreadsheets: pulling contract data from their billing system, manually tagging customer movements, and hoping nothing falls out of sync before the board meeting.

‍

DualEntry connects directly to your billing system — Stripe, Chargebee, Zuora, or others — and calculates both ARR as an operating metric and GAAP revenue under ASC 606 ^[¹^] from the same underlying contract data. No manual tagging, no separate spreadsheets, no reconciliation at month-end or compare your options in our revenue recognition software guide

‍

Every board period, it generates the ARR waterfall (new, expansion, churn, contraction) automatically. Live ARR, MRR, NRR, and CARR sit alongside your GAAP income statement, balance sheet, and cash flow statement. Everything updates in real time as contracts change.

‍

You'll know it's time to make the switch when your finance team is spending more time maintaining your ARR model and SaaS chart of accounts than analyzing them… or when an investor asks for an ARR-to-revenue reconciliation and you're not confident in the numbers.

‍

If your ARR and revenue numbers live in different places, that's the problem DualEntry solves. Schedule a demo to see how SaaS companies at your stage run both metrics from a single source of truth.

ARR vs Revenue FAQs

Is ARR profit or revenue?

ARR is neither profit nor revenue in the GAAP sense. It's an operating metric^[4] that represents the annualized value of active recurring subscriptions. It doesn't appear on the income statement. GAAP revenue (which does appear on the income statement) and ARR are often different because of recognition timing, non-recurring revenue streams, and contract start dates.

Can ARR be lower than revenue?

Yes. ARR can be lower than GAAP revenue when a company has significant non-recurring revenue streams (professional services, one-time fees, usage overages) that are included in GAAP revenue^[1] but not in ARR. ARR can also be lower if the company experienced contraction or churn during the period while still recognizing revenue from those customers.

Can ARR be higher than revenue?

Yes. ARR is often higher than trailing 12-month GAAP revenue in fast-growing SaaS companies. This is because ARR reflects the current annualized run rate (including recently signed contracts at full annual value). GAAP revenue only includes the months of service actually delivered during the period.^[1]

How do you convert revenue to ARR?

You can't simply convert total revenue to ARR because ARR excludes non-recurring items. To calculate ARR: take only your recurring subscription revenue, remove any one-time fees and professional services, then annualize the current monthly recurring subscription amount. ARR = current MRR (subscription only) × 12.

What is a good ARR growth rate?

A good ARR growth rate depends on your business stage. Early-stage SaaS companies (under $5M ARR) typically target 2–3× year-over-year growth. At $5–$20M ARR, 50–100% growth is considered strong. At $20–50M+ ARR, 30–50% is excellent.^[5] The Rule of 40 (growth rate + free cash flow margin ≥ 40%)^[3] is the widely used benchmark for balancing growth and efficiency — across McKinsey's analysis of more than 200 software companies between 2011 and 2021, businesses exceeded Rule of 40 performance only 16 percent of the time.^[3]

What is CARR vs ARR?

CARR (committed annual recurring revenue) includes signed contracts that haven't gone live yet. ARR only counts active, delivering subscriptions. CARR is always greater than or equal to ARR. The gap is largest in enterprise SaaS, where implementation can take significant time. For self-serve SaaS companies with instant activation, CARR and ARR are nearly identical.
