Annual Recurring Revenue (ARR): A Complete Guide
Annual Recurring Revenue (ARR) is the most important metric for understanding your SaaS business scale. Learn how to calculate, forecast, and grow ARR.
Annual Recurring Revenue (ARR) is the north star metric for SaaS businesses. It represents the annualized value of your subscription revenue and is the primary metric used by investors, analysts, and leadership teams to evaluate business scale and trajectory.
What Is ARR?
ARR is the annualized run rate of your recurring subscription revenue. It's calculated simply as:
ARR = MRR × 12
If your MRR is $50,000, your ARR is $600,000.
Unlike total revenue (which can include one-time fees, professional services, or hardware sales), ARR focuses exclusively on recurring subscription revenue. This makes it the purest measure of your business's recurring revenue health.
Why ARR Matters
ARR is the standard metric for:
- Valuation: SaaS companies are valued at multiples of ARR (typically 10x-30x for growth companies)
- Fundraising: Investors evaluate ARR growth rate as the primary investment criterion
- Benchmarking: Industry benchmarks are almost always expressed in ARR terms
- Strategic planning: ARR targets drive hiring, spending, and investment decisions
How to Calculate ARR
The simplest method: multiply your current MRR by 12. Use our ARR calculator for quick computation.
For a more accurate picture, calculate:
ARR = (Total Annual Subscription Revenue) - (One-Time Fees) - (Credits)
Net New ARR
Net New ARR measures the change in ARR over a period, accounting for:
- New ARR: From new customers
- Expansion ARR: From existing customer upgrades
- Contraction ARR: From downgrades
- Churn ARR: From lost customers
Net New ARR = New ARR + Expansion ARR - Contraction ARR - Churn ARR

| Series B | $5M - $20M | 5-10% MoM |

How to Grow ARR
Increase New Customer ARR
Acquire more customers at higher price points. Track your efficiency with our CAC calculator.
Drive Expansion ARR
Existing customers are your fastest growth path. Implement usage-based pricing, upgrade paths, and customer success motions. Measure with our NRR calculator.
Reduce Churn ARR
Every percentage point of churn reduction preserves ARR. Reducing churn from 5% to 4% monthly improves ARR growth by 12% annually. Use our churn calculator.
Common ARR Mistakes
- Including non-recurring revenue: Don't include setup fees, professional services, or one-time sales
- Annualizing early MRR: If you've only been in business for 3 months, ARR is a projection, not a fact
- Ignoring churn in forecasts: ARR growth requires accounting for the revenue you'll lose
ARR and Company Building
ARR is more than a number — it's a measure of the recurring value you're creating for customers. Every dollar of ARR represents a customer who finds enough value in your product to pay for it regularly.
