Who this is for
SaaS founders exploring Series A through growth equity, bootstrapped software operators preparing for a sale, and strategic acquirers benchmarking software targets will find this valuation most relevant.
What drives value in Subscription SaaS
- ARR growth rate and net revenue retention (NRR) above 100%
- Rule of 40 score (revenue growth % + EBITDA margin %)

- Churn rate and logo retention by cohort vintage
- Concentration of ARR in top 10 customers
Valuation methods we use
SaaS companies are valued primarily on ARR or revenue multiples calibrated to growth rate and the Rule of 40. DCF is applied for companies with predictable NTM revenue. Public SaaS comparable multiples provide a market cross-check. This tool is informational only. Output is driven by your inputs and does not constitute a formal appraisal or certified valuation.
Typical metrics and inputs
ARR
Annual recurring revenue; the primary revenue base metric for SaaS companies.
NRR
Net revenue retention including expansions, contractions, and churn; >110% is considered best-in-class.
CAC payback (months)
Months to recover customer acquisition cost from gross margin; <18 months is strong.
Rule of 40
Revenue growth rate plus EBITDA margin; >40 indicates efficient growth, supporting premium multiples.
Logo churn rate
Annual percentage of customers lost; <5% is strong for SMB, <2% for enterprise SaaS.
Example scenarios
High-growth vertical SaaS
A vertical SaaS tool at $3 M ARR growing 80% YoY with 115% NRR and 75% gross margins might trade at 8–12× ARR in a growth equity round.
Profitable SMB SaaS at scale
A bootstrapped SMB SaaS at $8 M ARR growing 25% with 35% EBITDA margins and a Rule of 40 score of 60 might be valued at 5–7× ARR in an M&A process.
Frequently asked questions
What ARR multiple is typical for SaaS?
Multiples range widely: 2–4× ARR for slow-growth profitable businesses, 6–12× for high-growth companies, and 15–25× for breakout category leaders.
How does NRR affect SaaS valuation?
NRR above 120% can add 1–3× to the ARR multiple because expansion revenue reduces effective churn and raises long-term LTV.
Does EBITDA matter for SaaS valuation?
At early stages, growth dominates. Above $10 M ARR, buyers increasingly weigh the Rule of 40 and path to EBITDA profitability.
What is the Rule of 40?
Revenue growth rate plus EBITDA margin percentage. A score above 40 signals efficient growth; it is heavily weighted in public and private SaaS valuations.
Is this a certified appraisal?
No. ValueAlpha provides AI-generated estimates for planning purposes. Engage a qualified M&A advisor for formal transaction valuations.
