ARR Calculator Guide: Annual Recurring Revenue for SaaS (2026)

By The hakaru Team·Last updated March 2026

Quick Answer

  • *ARR (Annual Recurring Revenue) = MRR × 12, or the sum of all annual subscription contract values — it excludes one-time fees, setup fees, and professional services
  • *ARR is the #1 valuation metric for SaaS companies; early-stage SaaS often trades at 5–15× ARR multiples
  • *Key ARR milestones: $1M ARR (product-market fit signal), $10M ARR (Series B territory), $100M ARR (unicorn path), $1B ARR (IPO-ready)
  • *The T2D3 growth path (triple twice, then double three times) is the benchmark for reaching $100M ARR in ~7 years from $1M ARR

What Is ARR (Annual Recurring Revenue)?

ARR is the annualized value of all active recurring subscription contracts. It answers a single question: “If nothing changes in our business, how much subscription revenue will we collect over the next 12 months?”

That predictability is why ARR has become the primary valuation currency for SaaS businesses. Unlike gross revenue — which lumps together subscriptions, one-time fees, professional services, and usage-based billing — ARR strips everything down to the recurring core. Investors and acquirers pay multiples on ARR because it represents durable, contractually committed revenue.

According to SaaStr’s Annual Survey (2025), ARR is the single most-cited top-line metric in SaaS board decks, used by 94% of venture-backed SaaS companies as their primary revenue KPI.

The ARR Formula

The simplest ARR formula is:

ARR = MRR × 12

Or, if you have annual contracts:

ARR = Sum of all active annual subscription contract values

For a company with a mix of monthly and annual subscribers, calculate ARR as: (monthly subscribers × monthly price × 12) + (annual subscribers × annual contract value).

Example: 200 customers on a $99/month plan and 50 customers on a $999/year plan.

  • Monthly subscribers: 200 × $99 × 12 = $237,600
  • Annual subscribers: 50 × $999 = $49,950
  • ARR = $287,550

ARR vs MRR vs TCV: Which Metric to Use When

These three metrics answer different questions. Using the wrong one in the wrong context misleads investors, boards, and your own team.

MetricWhat It MeasuresBest Used For
MRR (Monthly Recurring Revenue)Recurring revenue in a single monthDay-to-day operations, growth velocity, churn tracking
ARR (Annual Recurring Revenue)Annualized recurring revenue run rateValuation, fundraising, annual planning, investor reporting
TCV (Total Contract Value)Total value of a contract including all years and one-time feesEnterprise deals, bookings reporting, sales team incentives
ACV (Annual Contract Value)ARR from a single contract (TCV ÷ contract length in years)Average deal size benchmarking, quota setting

Early-stage startups (pre-$1M ARR) often track MRR because monthly changes are meaningful. Growth-stage companies ($5M+ ARR) shift to ARR as the primary board metric. Enterprise SaaS companies also track TCV to capture multi-year committed revenue.

ARR Milestones by Funding Stage

ARR is one of the clearest signals investors use to gauge stage. According to Bessemer Venture Partners’ State of the Cloud 2025 and Battery Ventures’ OpenCloud report, median ARR benchmarks by funding round are:

Funding StageTypical ARR RangeWhat Investors Look For
Pre-Seed$0–$100K ARREarly customer validation, founder–market fit
Seed$100K–$1M ARRInitial traction, repeatable sales motion emerging
Series A$1M–$5M ARRProduct-market fit, 80%+ gross retention, >100% NRR
Series B$5M–$20M ARRScalable go-to-market, strong NRR, efficient growth
Series C$20M–$75M ARRMarket leadership signals, category creation
Growth / Pre-IPO$75M–$300M+ ARRRule of 40 ≥40, durable growth, path to profitability
IPO-Ready$150M–$300M+ ARRConsistent growth, predictable margins, public market comps

According to OpenView’s SaaS Benchmarks 2025, the median Series A SaaS company had $2.4M ARR at time of raise, while the median Series B company had $11M ARR.

The T2D3 ARR Growth Benchmark

T2D3 — triple twice, then double three times — is the gold standard growth path for venture-backed SaaS, originally articulated by Mamoon Hamid at Battery Ventures. The path from $1M to roughly $100M ARR looks like this:

YearARR TargetGrowth Multiple
Year 1$1M ARRStarting point
Year 2$3M ARR3× (triple)
Year 3$9M ARR3× (triple)
Year 4$18M ARR2× (double)
Year 5$36M ARR2× (double)
Year 6$72M ARR2× (double)
Year 7$144M ARR2× (double)

Companies on the T2D3 path are typically on track for a $1B+ valuation. According to Bessemer, fewer than 1% of SaaS startups achieve this pace. But T2D3 provides useful benchmarks even if you don’t hit every milestone: if you’re growing at 150% year-over-year at $2M ARR, you’re tracking ahead of the triple targets.

How ARR Growth Rate Affects Valuation Multiples

ARR growth rate is the largest single driver of SaaS revenue multiples. The relationship is not linear — it is exponential at the high end.

ARR Growth Rate (YoY)Typical ARR Multiple (2025)Stage
>150%12–25× ARRHypergrowth (rare)
100%–150%8–15× ARRSeries A–B
50%–100%5–10× ARRSeries B–C
30%–50%4–7× ARRGrowth stage
15%–30%3–5× ARRMature / pre-profitability
<15%2–4× ARRValue / profitable SaaS

Note: these multiples compressed significantly from the 2021 peak (when 100%+ growth companies traded at 30–50× ARR). Bessemer’s 2025 State of the Cloudreport shows median public SaaS multiples normalized to 5–8× ARR for growth-stage companies, with a premium for Rule of 40 performers.

The Rule of 40— ARR growth rate + profit margin ≥ 40 — is increasingly used alongside raw ARR growth to capture business efficiency. A company growing at 60% with −5% profit margin scores 55 on the Rule of 40, which typically commands a premium multiple over a company growing at 60% with −30% margins.

5 Common ARR Calculation Mistakes

1. Including One-Time Fees

Setup fees, onboarding charges, and implementation services are not recurring. Including them overstates ARR and misleads investors about the true run rate of the business. Strip them out.

2. Including Professional Services

Custom development, training engagements, and consulting revenue are project-based. Even if they recur informally, they are not subscription revenue and should be excluded from ARR.

3. Counting Contracts Before They Start

ARR should only include active contracts where the subscription has begun. A signed annual contract that starts next quarter is a booking, not ARR. Add it to ARR when the subscription term commences.

4. Not Removing Churned Customers

ARR reflects active subscriptions only. When a customer cancels, their ARR must be subtracted immediately. Failing to do so creates “ghost ARR” that inflates your metrics.

5. Mixing Billing Currency Without Conversion

For companies with international customers, all contracts must be converted to a single currency at a consistent exchange rate. Mixing USD and EUR contract values without conversion introduces fluctuations that have nothing to do with business performance.

ARR vs Total Revenue: What’s the Difference?

Total revenue on your income statement includes everything: subscriptions, one-time fees, professional services, usage overages, and any other revenue streams. ARR captures only the recurring subscription portion.

For a typical SaaS company, ARR might represent 60–85% of total revenue. The gap is filled by services, setup, and usage. Investors care about the ARR share of total revenue as a quality signal — higher ARR share means more predictable, scalable revenue.

According to SaaStr’s 2025 benchmarks, top-quartile SaaS companies have 80%+ of total revenue in recurring subscriptions. Services-heavy SaaS companies (where professional services represent 30%+ of revenue) typically receive lower valuation multiples because that revenue is harder to scale and less predictable.

Frequently Asked Questions

What is ARR (Annual Recurring Revenue)?

ARR (Annual Recurring Revenue) is the annualized value of all recurring subscription revenue from active customers. It equals MRR × 12, or the sum of all annual contract values for active subscriptions. ARR excludes one-time fees, setup charges, and professional services — it captures only the predictable, recurring portion of revenue.

How is ARR calculated?

ARR = MRR × 12. Alternatively, ARR = sum of all active annual subscription contract values. For a SaaS company with 100 customers paying $500/month, ARR = $500 × 100 × 12 = $600,000. If some customers pay annually, count the full contract value. Always exclude one-time fees, professional services, and non-recurring revenue.

What is the difference between ARR and MRR?

MRR (Monthly Recurring Revenue) is the monthly snapshot of recurring revenue. ARR is the annualized version — simply MRR × 12. Early-stage startups often track MRR because it changes faster and reflects monthly momentum. Investors and acquirers use ARR for valuation because it represents the annual run rate of the business.

Does ARR include one-time fees or professional services?

No. ARR should only include recurring, predictable subscription revenue. One-time setup fees, implementation fees, professional services engagements, hardware revenue, and usage-based overages are excluded from ARR. Including them inflates ARR and misrepresents the true recurring nature of the business — which matters significantly for valuation multiples.

What is a good ARR growth rate for SaaS?

According to OpenView’s SaaS benchmarks, top-quartile SaaS companies grow ARR at 80–150% year-over-year at the $1–5M ARR stage. The T2D3 benchmark sets the bar for elite SaaS growth: triple from $1M to $3M ARR, triple again to $9M, then double to $18M, $36M, $72M, and $144M — reaching roughly $100M ARR in ~7 years.

How does ARR growth rate affect valuation multiples?

ARR growth rate is the single biggest driver of SaaS valuation multiples. According to Bessemer Venture Partners, SaaS companies growing ARR at 100%+ typically trade at 10–20× ARR. Companies growing at 50–100% trade at 6–12× ARR. Below 30% growth, multiples compress to 3–6× ARR. The Rule of 40 (growth rate + profit margin ≥ 40) is used alongside ARR growth to assess overall business quality.
