Free SaaS Valuation Calculator — ARR Multiple & Rule of 40 Estimator
SaaS company valuation is driven by ARR, growth rate, net revenue retention (NRR), gross margin, and the Rule of 40 score. This calculator applies growth-adjusted ARR multiples — the method used by most SaaS investors — and shows how each metric affects your estimated valuation range.
saas
Estimate your SaaS company valuation using ARR multiples, Rule of 40, and growth-adjusted models.
- Growth-adjusted ARR multiple range based on monthly MRR growth rate
- Rule of 40 score calculated from growth rate and estimated margin
- NRR quality adjustment — above 110% earns valuation premium
- Projected ARR in 12 months based on compound growth
- Valuation range (low–high) with multiple breakdown
- Valuation grade (A+/A/B/C) based on combined metrics
Everything you need in one SaaS Valuation Calculator
ARR multiple method
Applies the industry-standard ARR multiple approach: faster growth = higher multiple. Growth-adjusts from a base range and modifies for NRR quality, giving a realistic low-to-high valuation band.
Rule of 40 score
Calculates your Rule of 40 score (growth % + EBITDA margin %) — the key metric investors use to compare SaaS companies across growth stages. Score above 40 signals premium-multiple territory.
NRR quality signal
NRR above 100% earns a multiple premium because existing customers are growing revenue without additional CAC. Below 90% NRR signals product or market problems that compress multiples.
12-month ARR projection
Projects your ARR in 12 months based on compound monthly growth — showing investors what multiple they are paying on forward ARR, which is how most term sheets are structured.
How to use SaaS Valuation Calculator
Enter your ARR and growth rate
ARR is Annual Recurring Revenue. Monthly growth rate is used to calculate the growth-adjusted multiple — faster-growing companies command higher multiples.
Add NRR and gross margin
NRR (Net Revenue Retention) above 100% signals expansion revenue and earns a premium. Gross margin above 70% is expected for SaaS.

SaaS ARR multiple benchmarks by growth rate
| Monthly MRR Growth | Annualized Growth | Typical ARR Multiple | Rule of 40 Target |
|---|---|---|---|
| < 5% MoM | < 80% YoY | 3–5× ARR | 30+ (margin-driven) |
| 5–10% MoM | 80–214% YoY | 5–8× ARR | 40+ |
| 10–20% MoM | 214–792% YoY | 8–15× ARR | 50+ |
| > 20% MoM | > 792% YoY (T2D3) | 15–25× ARR | 60+ |

ARR = current MRR × 12If NRR is above 100%, forward ARR will exceed MRR × 12. Investors typically value on forward ARR (projected 12-month ARR based on current MRR × growth rate). Use the MRR growth simulator for the projection.
Valuation = ARR × multiple (no margin input)Gross margin below 60% compresses SaaS multiples significantly. A 60% GM SaaS at the same ARR and growth as an 80% GM SaaS may receive 30–40% lower multiples. Margin is not optional context.
Using total revenue (including services) for the ARR multipleARR multiples apply to recurring subscription revenue only. Professional services, one-time fees, and usage-based revenue that is not committed should be excluded or separated in the model.
Expected 20× ARR based on 2021 compsPublic SaaS multiples peaked at 20–40× ARR in 2021 and compressed to 4–10× by 2024. Use current public SaaS comparable multiples (Bessemer Cloud 100, BVP Nasdaq Emerging Cloud Index) as your benchmark floor.
Pitch deck: ARR and growth onlySophisticated SaaS investors calculate Rule of 40 immediately. Present it proactively: growth rate + EBITDA margin. If the score is below 40, explain the path — accelerating growth or improving margins — before they ask.
NRR reported when GRR was calculatedGRR (Gross Revenue Retention) caps at 100% — it excludes expansion. NRR includes expansion and can exceed 100%. Always clarify which metric you are reporting. Investors will ask if you do not.

Frequently asked questions
SaaS companies are primarily valued on ARR (Annual Recurring Revenue) multiples — typically 4–20x ARR depending on growth rate, NRR, gross margin, and market conditions. The Rule of 40 (growth rate + profit margin ≥ 40) and NRR above 100% are the strongest drivers of premium multiples.
