Annual Recurring Revenue (ARR): Formula and Examples

Annual recurring revenue is the single number investors ask for first, and it's the metric your whole SaaS pipeline planning should anchor on. ARR tells you how much predictable, subscription-based revenue your business will generate in a year, stripped of one-time noise.

What is annual recurring revenue (ARR)?

Annual recurring revenue is the normalized yearly value of all active subscription contracts. It captures only recurring charges: the revenue your business can count on renewing, expressed on a per-year basis.

It is not total revenue. It doesn't include setup fees, one-time professional services, or usage overages. ARR is the stable, contractual core.

Key facts: annual recurring revenue

• Median ARR growth rate for private B2B SaaS companies was 25% in 2024, down from 30% in 2023 (SaaS Capital, 2024)
• SaaS companies are typically valued at 1x to 12x ARR, with high-growth companies (50%+ growth) often exceeding 8x (Wall Street Prep, 2025)
• Median net revenue retention (NRR) for private B2B SaaS sits at 106%, meaning the average company grows ARR from its existing base alone (SaaS Capital, 2025)

The ARR formula

The simplest form:

ARR = Number of customers x Average annual contract value (ACV)

Or, if you're pulling from MRR:

ARR = MRR x 12

Worked example

Say you have 80 customers. Forty pay $6,000 per year, thirty pay $12,000 per year, and ten pay $30,000 per year.

• 40 x $6,000 = $240,000
• 30 x $12,000 = $360,000
• 10 x $30,000 = $300,000
• Total ARR = $900,000

Multi-year contracts. If a customer signs a 3-year deal worth $90,000 total, you count $30,000 in ARR, not $90,000. You normalize to the per-year value. The cash may arrive upfront (affecting cash flow), but ARR reflects only the annual recurring portion.

Monthly subscribers. Multiply their monthly fee by 12. A $500/month customer contributes $6,000 to ARR.

ARR vs MRR

Both measure recurring subscription revenue, but they serve different purposes.

If your deals are primarily annual or multi-year, ARR is the right headline metric. If you sell monthly subscriptions with frequent upgrades and churns, MRR gives you a tighter feedback loop. Most B2B companies track both.

What counts (and what doesn't) in ARR

Getting ARR wrong is easy if you include revenue that isn't truly recurring.

Include in ARR:

• Fixed subscription fees (monthly or annual, normalized to yearly)
• Committed seat-based licenses
• Recurring platform fees with defined renewal terms
• Automatic renewals at a set price

Exclude from ARR:

• One-time implementation or onboarding fees
• Professional services and consulting engagements
• Non-recurring training or workshop fees
• Usage-based overages beyond a committed tier (unless they're a predictable contracted minimum)
• Setup charges

The test is simple: will this revenue renew next year under the same contract terms? If yes, it belongs in ARR. If it depends on a separate statement of work or a variable event, leave it out.

Components: new, expansion, contraction, and churned ARR

ARR isn't a single monolithic number. It's made up of four moving parts, and understanding each one tells you where your growth is actually coming from.

New ARR is revenue from customers signing up for the first time. It's the output of your sales pipeline and the most obvious growth driver.

Expansion ARR comes from existing customers buying more: upgrades, additional seats, higher tiers, or new product modules. This is often the cheapest ARR to generate because you already own the relationship.

Contraction ARR is lost revenue from customers who downgrade rather than cancel. A customer moving from a $24,000 plan to a $12,000 plan reduces ARR by $12,000. It's a warning signal worth watching separately from churn.

Churned ARR is revenue lost from customers who cancel entirely.

The interplay of these four components drives net revenue retention (NRR), the ratio of ending ARR from your existing customer base to beginning ARR. An NRR above 100% means your existing customers expand faster than they churn - your ARR grows even if you close zero new deals. Industry median sits around 106%, per SaaS Capital data.

Understanding the component mix matters for pipeline decisions too. If expansion ARR is strong, you might invest more in customer success and upsell motions. If new ARR is the only growth driver, you're one bad quarter away from a stall. See pipeline metrics overview for how these components tie into broader pipeline health.

Why ARR matters

Investors use it as their primary valuation input. ARR multiples - the ratio of company value to ARR - are the standard language of SaaS fundraising. When a VC says "we're looking at 8x revenue," they mean 8x ARR.

It makes forecasting honest. Because ARR excludes one-time revenue, it gives you a clean baseline for revenue predictability. You know the floor you're working from before adding new sales.

It aligns the whole company. Sales, finance, and customer success can all tie their work back to a single number. Sales closes new ARR. CS defends and grows existing ARR. Finance reports on net ARR changes to the board.

It surfaces problems early. A flat or declining ARR number catches issues before they hit your bank account. If contraction and churn are eating your new ARR faster than the pipeline can fill the gap, that gap shows up in ARR movement before it hits cash flow.

It drives acquisition cost decisions. Knowing your ARR per customer lets you calculate customer acquisition cost payback and the LTV:CAC ratio that investors and operators care about. Without clean ARR figures, those calculations fall apart.

How to calculate and grow ARR

Step 1: Pull your active contracts

Export every active subscription with its contract start date, end date, and total contract value. Multi-year contracts get divided by the number of years to get annual value.

Step 2: Categorize each revenue line

Mark each line as subscription (include) or one-time (exclude). If a contract mixes both, split the recurring portion out. Be consistent: your ARR definition needs to hold quarter over quarter for comparisons to mean anything.

Step 3: Segment by component

Sort your ARR into new, expansion, contraction, and churned buckets. Calculate beginning ARR plus new and expansion, minus contraction and churn, to get ending ARR. Calculate NRR to benchmark your retention health.

Step 4: Build the growth levers

ARR grows through four paths:

1. Close more new deals (sales volume and win rate improvement)
2. Increase average contract value (pricing, packaging, deal size optimization)
3. Reduce churn (onboarding quality, product stickiness, customer success investment)
4. Drive expansion (upsell motions, usage-triggered upgrades, expansion playbooks)

Most companies focus almost entirely on new ARR and underinvest in expansion. But if your NRR is 90%, you're losing 10% of your base every year before you write a single new proposal. Fixing retention has a compounding effect that new logos can't replicate.

Link your ARR targets to your sales forecasting methods so you know whether the pipeline can realistically deliver the new ARR your growth plan requires.

ARR examples

Early-stage: seed-funded B2B SaaS

A startup has 25 customers on annual plans averaging $8,400/year.

• ARR = 25 x $8,400 = $210,000

New ARR from closed deals this quarter: $42,000. One customer downgraded from $8,400 to $4,200 (contraction: -$4,200). No churns. Net ARR change: +$37,800. Ending ARR: $247,800.

Growth-stage: mixed annual and monthly

NRR for the quarter: expansion deals added $48,000, one churn removed $24,000, two downgrades removed $7,200. NRR = ($665,280 + $48,000 - $24,000 - $7,200) / $665,280 = 103%.

Scale-stage: enterprise-heavy mix

A $10M ARR company with 80% of revenue in annual enterprise contracts and 20% in SMB monthly. The enterprise contracts average $125,000 ACV. The SMB base runs about $1,800/year per customer.

If the enterprise segment has 60 customers: 60 x $125,000 = $7.5M ARR from enterprise. The remaining $2.5M comes from the SMB monthly base (about 1,389 SMB customers at $1,800/year).

Understanding this split matters for pipeline planning: enterprise deals are fewer but larger, so one lost renewal moves the ARR needle significantly. That's why enterprise-heavy companies build deal inspection processes and monitor forecast accuracy tightly.

Frequently asked questions

Is ARR the same as total revenue?

No. Total revenue includes all recognized revenue: one-time fees, professional services, hardware, and usage charges. ARR includes only the recurring subscription portion. For most SaaS companies, ARR is smaller than total revenue, sometimes significantly.

Can ARR decrease?

Yes. If churn and contraction outpace new and expansion ARR, your ARR shrinks. Negative ARR growth is a serious signal that something is broken in either the product-market fit, onboarding, or customer success motion.

How often should you report ARR?

Most companies report ARR at the end of each month and quarter. Real-time dashboards update as contracts are signed or cancelled. The key is consistency: always measure as of the same date and with the same inclusion rules.

What's the difference between ARR and ACV?

Annual contract value (ACV) is the yearly value of a single contract. ARR aggregates ACV across all active contracts. A customer with a $50,000 ACV contributes $50,000 to your total ARR.

Does a free trial period affect ARR?

Not until the customer converts to a paying plan. Free trials and freemium users contribute zero ARR. Once they sign a paid subscription, their annual value gets added to ARR on the contract start date.

Clean ARR tracking is the foundation of everything downstream: accurate forecasting, sound pipeline metrics, trustworthy board reports, and clear unit economics. Start with a precise definition, apply it consistently, and the rest of your SaaS metrics fall into place.
