ARR Calculator
Calculate your Annual Recurring Revenue from MRR or subscriber count and ARPU. See quarterly revenue and growth projections. Everything runs in your browser — no data is stored or sent to any server.
How It Works
The ARR Calculator offers two calculation modes. In MRR mode, you enter your current Monthly Recurring Revenue and the calculator computes your Annual Recurring Revenue, quarterly revenue, and growth projections. In Subscriber mode, you enter your number of subscribers and average revenue per user (ARPU), and the calculator derives MRR, ARR, quarterly revenue, and projected growth at various rates.
Annual Recurring Revenue (ARR) is the most important financial metric for subscription-based businesses. It represents the annualized value of your recurring revenue streams and is the primary metric used by investors, analysts, and leadership teams to evaluate the health and trajectory of a SaaS or subscription business.
Formulas
ARR = MRR × 12
MRR = Subscribers × ARPU
Quarterly Revenue = ARR / 4
Projected ARR = ARR × (1 + Growth Rate)
Where:
- MRR = Monthly Recurring Revenue
- ARPU = Average Revenue Per User (monthly)
- Subscribers = Total active paying subscribers
- Growth Rate = Expected annual growth rate as a decimal
Why ARR Matters
ARR is the gold standard metric for subscription businesses because it normalizes revenue into an annualized figure that accounts for the recurring nature of the revenue stream. Unlike one-time revenue, recurring revenue is predictable and compounds over time, making it the most valuable type of revenue for building long-term business value. Investors use ARR to benchmark companies, calculate valuation multiples, and assess growth trajectories.
Tracking ARR over time reveals trends in your business that monthly snapshots can obscure. A steadily growing ARR indicates healthy customer acquisition and retention, while flat or declining ARR signals problems with churn, pricing, or market fit that need immediate attention.
ARR vs. MRR
MRR (Monthly Recurring Revenue) and ARR are closely related but serve different purposes. MRR is better for short-term operational decisions — tracking month-over-month changes, evaluating the impact of a new pricing plan, or monitoring churn trends. ARR is better for long-term strategic planning — annual budgeting, fundraising conversations, valuation discussions, and year-over-year comparisons. In general, early-stage startups focus more on MRR while later-stage companies emphasize ARR.
Growth Projections
- 10% growth is a conservative target suitable for mature, stable businesses in established markets.
- 25% growth represents solid performance for mid-stage companies with proven product-market fit.
- 50% growth is an aggressive target typical of high-growth startups in expanding markets.
- 100% growth (doubling) is exceptional and usually seen only in early-stage companies with strong viral loops or network effects.
Examples
Example 1: MRR-Based Calculation
A SaaS company has $25,000 in Monthly Recurring Revenue.
- ARR = $25,000 × 12 = $300,000
- Quarterly Revenue = $300,000 / 4 = $75,000
- ARR at 25% Growth = $300,000 × 1.25 = $375,000
Example 2: Subscriber-Based Calculation
A subscription service has 2,000 subscribers paying an average of $49/month.
- MRR = 2,000 × $49 = $98,000
- ARR = $98,000 × 12 = $1,176,000
- Quarterly Revenue = $1,176,000 / 4 = $294,000
Example 3: Early-Stage Startup
A new SaaS product has 150 subscribers at $19/month ARPU.
Counting Annual and Multi-Year Contracts in ARR
ARR should reflect the recurring value of every active contract, normalized to a single year — regardless of how often the customer is billed. The formula ARR = MRR × 12 works perfectly when everyone pays monthly, but most subscription businesses mix billing terms. The rule is simple: convert each contract to its annualized recurring value, then total them.
- Monthly plan — multiply the monthly price by 12. A $99/month plan contributes $1,188 to ARR.
- Annual prepaid plan — the full yearly price is the ARR contribution. A $1,000/year plan adds $1,000, not $12,000.
- Multi-year contract — divide the total contract value by its length in years. A $60,000 three-year deal contributes $20,000 per year to ARR.
Exclude anything non-recurring — setup fees, one-time onboarding, usage overages, and professional services — because these do not renew. To use the calculator above, sum every contract's annualized value into a single ARR figure, or divide it by 12 to enter an equivalent MRR.
- MRR = 150 × $19 = $2,850
- ARR = $2,850 × 12 = $34,200
- ARR at 100% Growth = $34,200 × 2 = $68,400
Frequently Asked Questions
What is ARR?
ARR stands for Annual Recurring Revenue. It is the annualized value of recurring subscription revenue, calculated by multiplying your Monthly Recurring Revenue (MRR) by 12. ARR is the primary metric used to measure the size and growth of subscription-based businesses, particularly SaaS companies.
What is the difference between ARR and total revenue?
ARR only includes recurring revenue from subscriptions. It excludes one-time fees, setup charges, professional services revenue, and non-recurring income. Total revenue includes all sources of income. ARR is considered more valuable because recurring revenue is predictable and has a higher valuation multiple than one-time revenue.
What is ARPU and how is it calculated?
ARPU stands for Average Revenue Per User. It is calculated by dividing your total MRR by the number of active paying subscribers. ARPU helps you understand the average value of each customer and is useful for pricing analysis, segmentation, and forecasting.
What is a good ARR growth rate?
Growth benchmarks vary by stage. Early-stage startups (under $1M ARR) often target 100%+ annual growth. Growth-stage companies ($1M-$10M ARR) typically aim for 50-100% growth. Later-stage companies ($10M+ ARR) usually target 25-50% growth. The "Triple Triple Double Double Double" framework suggests tripling ARR twice then doubling three times to reach $100M+ ARR.
Should I use ARR or MRR?
Both metrics are valuable but serve different purposes. Use MRR for month-to-month operational tracking, evaluating short-term trends, and measuring the impact of pricing changes. Use ARR for annual planning, fundraising, valuation discussions, and year-over-year comparisons. Most SaaS companies track both and report ARR to investors and MRR to the operations team.
