ARR Calculator

Calculate annual recurring revenue from MRR or individual contracts. Convert monthly to annual revenue instantly.

Quick Answer

ARR = MRR x 12. If your monthly recurring revenue is $50,000, your ARR is $600,000. For individual contracts, normalize each to a monthly value first.

Calculate ARR

Choose your input method: enter MRR directly or add individual contracts.

About This Tool

The ARR Calculator helps SaaS founders, finance teams, and investors quickly calculate annual recurring revenue from monthly recurring revenue or individual contracts. ARR is the foundational metric for SaaS businesses, serving as the basis for valuation, growth tracking, and financial planning.

Understanding Annual Recurring Revenue

Annual Recurring Revenue (ARR) represents the annualized value of your active subscription contracts. Unlike total revenue, ARR only includes predictable, recurring subscription income. It excludes one-time fees (setup, migration, training), professional services revenue, variable usage charges that are not contractually committed, and hardware or physical product sales. ARR provides a normalized view of your subscription business that makes it easy to track growth, compare periods, and benchmark against other SaaS companies.

MRR to ARR Conversion

The simplest ARR calculation is MRR multiplied by 12. Monthly Recurring Revenue is the sum of all active subscription revenue in a given month, normalized to monthly values. A customer paying $1,200/year contributes $100/month to MRR and $1,200 to ARR. When multiplying MRR by 12, you are assuming the current month's revenue level continues for a full year. This is why ARR is described as a run rate, not a forecast. It does not predict the future but rather annualizes the present state.

Calculating ARR from Contracts

When working with individual contracts of varying lengths, normalize each contract to a monthly equivalent before summing. A $60,000 contract over 24 months contributes $2,500/month to MRR. A $36,000 contract over 12 months contributes $3,000/month. Sum all monthly contributions, then multiply by 12 for ARR. This approach handles mixed contract lengths (monthly, annual, multi-year) correctly and gives an accurate picture of your recurring revenue run rate.

ARR Growth and Decomposition

Understanding where ARR growth comes from is as important as the total number. ARR growth decomposes into four components: new ARR (from new customers), expansion ARR (from upsells and cross-sells to existing customers), contraction ARR (from downgrades), and churned ARR (from cancellations). Net new ARR = new + expansion - contraction - churned. Best-in-class SaaS companies generate significant expansion ARR, with net dollar retention rates above 120%, meaning they grow revenue from existing customers faster than they lose it.

ARR as a Valuation Driver

ARR is the primary input for SaaS company valuations. Public SaaS companies typically trade at 5-25x forward ARR, depending on growth rate, profitability, retention, and market conditions. Private companies at Series A-C stages are valued at 10-40x ARR for top performers. The ARR multiple reflects investor confidence in the durability and growth potential of the recurring revenue stream. Companies with higher net retention, faster growth, and better margins command premium multiples, while those with high churn or slowing growth see compressed valuations.

Frequently Asked Questions

What is Annual Recurring Revenue (ARR)?
ARR is the annualized value of your recurring subscription revenue. For monthly subscriptions, ARR equals MRR multiplied by 12. For annual or multi-year contracts, ARR is the total contract value divided by the contract length in years (or normalized to a 12-month period). ARR is the standard top-line metric for SaaS businesses because it represents the predictable, recurring revenue run rate. It excludes one-time fees, professional services, and variable usage charges unless they are contractually committed.
What is the difference between ARR and revenue?
ARR represents the annualized run rate of recurring subscription revenue, while total revenue includes all income sources: subscriptions, one-time setup fees, professional services, usage overages, and other non-recurring charges. ARR is forward-looking (what you would earn if current subscriptions continue for 12 months), while revenue is backward-looking (what you actually earned). Investors focus on ARR for SaaS valuation because recurring revenue is more predictable and valuable than one-time revenue.
How do I calculate ARR from monthly subscriptions?
For monthly subscriptions, ARR = MRR x 12. If your monthly recurring revenue is $50,000, your ARR is $600,000. Make sure to include only recurring subscription revenue in MRR. Exclude one-time charges, implementation fees, and variable usage that is not contractually committed. If you have a mix of monthly and annual subscribers, calculate the monthly equivalent for annual subscribers (annual price / 12) and add it to your MRR before multiplying by 12.
How do I calculate ARR from individual contracts?
For individual contracts, normalize each contract to a monthly value by dividing the total contract value by the number of months, then sum all monthly values and multiply by 12. For example, a $24,000/24-month contract contributes $1,000/month to MRR and $12,000 to ARR. A $60,000/12-month contract contributes $5,000/month and $60,000 to ARR. This calculator handles this normalization automatically when you enter individual contracts.
What ARR milestones matter for SaaS companies?
Key ARR milestones include: $1M ARR (product-market fit validation, often triggers Series A conversations), $5M ARR (repeatable sales process, often Series B territory), $10M ARR (scaling operations, potential for profitability), $50M ARR (IPO consideration for high-growth companies), and $100M ARR (the benchmark for a large, scaled SaaS business). Growth rates expected at each milestone decrease: 3x+ at $1M, 2-3x at $5M, 1.5-2x at $10M, and 30-50% at $50M+.
Should I use ARR or MRR to track my SaaS business?
Most SaaS businesses track both, but the primary metric depends on your contract structure. If most customers are on monthly plans, MRR is more natural and captures changes faster. If most customers sign annual or multi-year contracts, ARR is more appropriate. Investors generally prefer ARR because it is easier to compare across companies and calculate valuation multiples. For internal operations, MRR is often more useful because it highlights month-to-month changes in new, expansion, contraction, and churned revenue.
