Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual ARR growth rate | Total ARR growth |
|---|---|---|
| $2M to $5M over 3yr | 35.72% | 150.00% |
| $500k to $4M over 4yr | 68.18% | 700.00% |
| $10M to $25M over 5yr | 20.11% | 150.00% |
| $1M to $900k over 1yr | -10.00% | -10.00% |
How This Calculator Works
Enter ARR at the start and end of the period, with the years between them. The calculator finds the compound annual growth rate, the steady yearly pace that connects the two figures.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
ARR rising from $2M to $5M over 3 years is an annual growth rate of about 35.7%. Total growth is 150%, but the annual rate is what compares against benchmarks like Bessemer's T2D3 path and a previous fundraising round.
Key Insight
ARR growth is a net figure — new logos and expansion, less churn and downgrades. A 35% headline can hide a worrying churn pattern underneath. Pair the growth rate with net dollar retention and the gross-vs-net split to see the real engine.
T2D3 and the Rule of 40 — the growth-rate benchmarks investors use
Two industry conventions dominate SaaS growth-rate evaluation. T2D3 ('Triple, Triple, Double, Double, Double') describes the canonical fast-growing SaaS trajectory: a startup goes from $1M to $3M ARR (triple), then $9M (triple), then $18M (double), then $36M, then $72M. Reaching $100M ARR in 5-7 years from product-market fit is the T2D3 benchmark, originally articulated by Battery Ventures' Neeraj Agrawal. Few SaaS companies actually hit T2D3 — those that do (Slack, Zoom, Datadog historically) typically reach decacorn valuation.
The Rule of 40 — growth rate + EBITDA margin ≥ 40% — is the standard public-SaaS health metric. A company growing 60% with -20% EBITDA margin meets the rule; so does a company growing 20% with 20% margin. The Rule of 40 captures the trade-off between growth and profitability — investors will accept low or negative profitability if growth compensates, but only up to a point. Public SaaS companies trade at meaningful premiums to peers when they are above the Rule of 40.
By stage, SaaS Capital's annual benchmarks (2024 report) show median YoY ARR growth: <$1M ARR = 150%+; $1-5M ARR = 80-100%; $5-20M ARR = 50-70%; $20-50M ARR = 40-50%; $50-100M ARR = 30-40%; $100M+ = 25-35%. Falling below median for your stage is a signal to investors that something is breaking — typically a slowdown in lead generation, an increase in sales cycle, or an underperforming product gap.
Gross vs net ARR growth — where to look first
Headline ARR growth combines three sources: new logo ARR (signed new customers), expansion ARR (existing customers paying more — seat additions, upgrades, cross-sell) and churn ARR (lost customers or downgrades). Gross ARR growth = new + expansion. Net ARR growth = new + expansion − churn. Most SaaS reports use net.
Healthy SaaS businesses show all three: meaningful new-logo growth (40-60% of net ARR growth at scale), strong expansion (30-50%), and limited churn (gross dollar churn 5-10% annually for SMB SaaS; 2-5% for enterprise). When expansion outpaces new-logo growth meaningfully, the company has shifted from acquisition-led to retention-led growth — a sign of product maturity but also a warning that new-logo acquisition is slowing.
Net Dollar Retention (NDR) is the related metric — (existing ARR + expansion − churn) / existing ARR. NDR ≥ 110% is healthy; NDR ≥ 120% is elite (Snowflake, Datadog, ServiceNow historically). When NDR drops below 100%, existing customers contract net of churn — a structural issue that even strong new-logo acquisition cannot mask indefinitely. Read NDR before celebrating headline ARR growth.
ARR vs MRR vs CARR — get the definition right before the rate
A growth rate is only as trustworthy as the ARR figure underneath it, and three different bases are routinely reported as 'ARR'. Strict ARR annualizes only live, recurring subscription revenue (MRR × 12) and excludes one-time fees, professional services and non-recurring usage overage. MRR is the same quantity at monthly cadence — useful because the SaaS Quick Ratio (new + expansion MRR ÷ churned + contraction MRR; ≥ 4 is healthy) is built on it. CARR (Committed ARR) adds signed-but-not-yet-live contracts and ramp deals at full contract value, which can inflate the base by 10-30% versus live ARR at fast-growing companies. Comparing your CARR growth to a peer's live-ARR growth is a common apples-to-oranges error.
The operational discipline is to fix one definition and apply it across every period in the comparison. Two failure modes recur: reclassifying professional-services revenue into the recurring line mid-year (which manufactures growth that isn't recurring), and adding M&A-acquired ARR to the base without restating the prior period (which double-counts inorganic growth as organic). For board and investor reporting, separate organic ARR growth from total, and disclose whether the figure is live ARR or CARR. A 35% headline that is 20% organic live-ARR growth plus 15% from an acquisition and ramp accounting is a materially different business than a clean 35% organic number.
ARR growth benchmarks by stage — SaaS Capital 2024 median
Reference annual ARR growth rates by SaaS company stage. These are medians — top-quartile growth rates run 30-50% higher; bottom-quartile run materially lower.
| ARR scale | Median YoY growth | Top quartile | Notes |
|---|---|---|---|
| <$1M | 150%+ | 300%+ | Post-PMF, pre-scale |
| $1-5M | 80-100% | 150%+ | Early scaling; founder-led sales |
| $5-20M | 50-70% | 100%+ | First sales team build-out |
| $20-50M | 40-50% | 75%+ | Repeatable sales motion |
| $50-100M | 30-40% | 60%+ | Multi-product motion typical |
| $100-250M | 25-35% | 50%+ | Late-stage; IPO candidates |
| $250M-$1B | 20-30% | 40%+ | Public or near-public |
| >$1B (mature public) | 15-25% | 35%+ | Established platforms |
These benchmarks are for healthy unit economics (LTV/CAC ≥ 3, payback ≤ 18 months). Companies growing at the same rate with worse unit economics are valued at lower multiples. Combine ARR growth with the Rule of 40 (growth + EBITDA margin) for a more complete picture.
Frequently Asked Questions
What is ARR?
Annual recurring revenue — the annualized value of a SaaS business's contracted subscriptions. It excludes one-time fees and services revenue.
Why use the annualized rate?
Total growth depends on the window. Annualizing lets you compare against benchmarks, prior periods, and other companies on equal footing.
Does this account for churn?
Only as part of the net. ARR growth bundles new business and expansion with churn and contraction. Track gross new ARR and churn ARR separately for the real picture.
What is a healthy SaaS growth rate?
Early-stage SaaS often triples or doubles annually. Public SaaS leaders run 20% to 40%; below 20% with positive net retention is steady-state territory.
How is this different from MRR growth?
MRR is the monthly equivalent of ARR — same business, different cadence. The growth rate works out the same when annualized.
When is this calculator unreliable?
When ARR is inconsistently defined across periods (e.g., reclassifying professional services into recurring revenue inflates growth), after M&A where acquired ARR is added without adjustment, when a single very large contract distorts a quarter, or when comparing companies that use different ARR conventions (some include ramp deals at full contract value; others recognize only the first-year amount). For internal trends, also separate gross from net ARR growth — strong new logo growth can mask deteriorating retention.

Methodology & Review
ARR (Annual Recurring Revenue) growth rate equals (ending ARR − starting ARR) / starting ARR, expressed as a percentage. ARR includes only recurring subscription revenue normalized to an annual basis — exclude one-time setup fees, professional services revenue (unless explicitly bundled into a multi-year subscription) and non-recurring revenue. The calculator returns the period-over-period growth rate; common periods are month-over-month (MoM), quarter-over-quarter (QoQ) and year-over-year (YoY). For benchmarking against public SaaS peers, YoY ARR growth is the canonical metric. For internal operating cadence, MoM ARR growth tracks pipeline velocity and is the standard CEO metric in early-stage SaaS. RELIABILITY: Reliable when ARR is consistently defined and reported across periods (same exclusions, same currency conversion, same date of measurement). Less reliable in the presence of large one-time contracts that distort a single period, after M&A (acquired ARR inflates the growth rate), or when comparing companies with different reporting conventions (CARR — Committed ARR including ramp deals — vs traditional ARR).
