Annual Recurring Revenue (ARR)

ARR

Annual Recurring Revenue (ARR) is the annualized value of all active subscriptions, calculated as MRR multiplied by 12. It is the primary valuation anchor for SaaS businesses, used in fundraising decks, M&A conversations, and board reporting. ARR abstracts away monthly volatility and shows the run-rate scale of the business.

formula.sh

ARR = MRR × 12

> MRR: sum of all normalized monthly subscription revenue
> Multiply by 12 to annualize — this assumes the current MRR holds for 12 months
> For businesses with true annual contracts, ARR can also be summed directly from contract values

Your current MRR is $42,000.

$42,000 × 12

→ $504,000 ARR

why it matters

ARR is the language of SaaS valuation. When investors say a company is trading at "10x ARR," they mean enterprise value equals ten times the current annualized subscription revenue. Knowing your ARR lets you benchmark against public SaaS multiples and understand how your business would be valued in a fundraise or acquisition.

ARR is also useful for planning headcount, infrastructure costs, and marketing spend. Scaling from $1M to $10M ARR typically requires different GTM motions, team structures, and product investments — ARR milestones serve as natural inflection points for these decisions.

common mistakes

✗Conflating ARR with actual revenue collected — ARR is a run-rate metric, not cash in the bank

✗Including professional services or one-time fees in the ARR figure

✗Using ARR to forecast without adjusting for churn — ARR assumes current MRR is stable

pro tips

✓Track ARR per customer segment (SMB vs. mid-market vs. enterprise) to understand where your growth engine is firing

✓Set ARR milestones ($100K, $1M, $10M) as team-wide goals — they create shared focus

✓When reporting to investors, always show ARR alongside net revenue retention so the quality of the ARR is visible

the mrrsucks take

Congratulations, you have an ARR. It is annual, it recurs, and it is revenue — technically all three boxes checked. The fact that it fits on a Post-it note is a separate conversation.

faq

When should I use ARR instead of MRR?+

Use ARR in board decks, fundraising materials, and annual planning. Use MRR for operational monitoring, cohort analysis, and month-to-month decision-making.

Can a company have ARR without any annual contracts?+

Yes. ARR = MRR × 12 regardless of whether customers pay monthly or annually. It is a normalization, not a contract type.
