Rule of 40: growth rate + profit margin should total ≥ 40% (a balance of growth and profitability investors prize). Valuation = ARR × multiple; the suggested multiple band is a rough, market-dependent guide driven mainly by growth and retention. Real multiples swing widely with market conditions, NRR, and margins — this is a ballpark, not an appraisal. Informational, not financial advice.
About this tool
SaaS companies are valued primarily as a multiple of their annual recurring revenue (ARR), with the multiple driven by growth, retention, and profitability. This calculator estimates a valuation as ARR times a multiple you set, and computes the Rule of 40 — the investor heuristic that a healthy SaaS business should have its growth rate plus profit margin total at least 40%, balancing the trade-off between growing fast and burning cash. A company growing 60% with a −10% margin scores 50 and passes; one growing 20% at break-even scores 20 and does not. It also suggests a rough ARR-multiple band based on growth rate, since faster-growing companies command higher multiples. The crucial caveat, stated plainly: revenue multiples are highly market-dependent and swing dramatically with interest rates, sector sentiment, net revenue retention, and margins — public SaaS multiples have ranged from low single digits to 20×+ in different years. So treat the output as a ballpark for discussion, not an appraisal. It is informational, not financial advice. Everything runs in your browser.

- Review the Rule of 40 score and whether it passes.
- Adjust the ARR multiple toward the suggested band for your growth.
- Read the valuation estimate — treat it as a ballpark, not an appraisal.
Frequently asked questions
- What is the Rule of 40?
- A SaaS health heuristic: growth rate plus profit margin should be at least 40%. It captures the trade-off between growth and profitability — a company can grow fast and lose money, or grow slowly and be profitable, but the sum should clear 40% to be considered efficient.
- How are SaaS companies valued?
- Most commonly as a multiple of ARR (annual recurring revenue). Valuation = ARR × multiple. The multiple is set by growth rate, net revenue retention, gross margin, market size, and overall market conditions — growth is usually the biggest driver.
- What ARR multiple is realistic?
- It varies enormously with the market. Rough private-market bands by growth: ~2–4× for slow growth, 6–10× for strong growth, 10–15×+ for hypergrowth — but these shift with interest rates and sentiment. Public SaaS multiples have ranged from ~3× to over 20× in different years. Use current comparables.
- Why is the valuation only a ballpark?
- Revenue multiples are not a precise formula — they reflect market sentiment, comparable transactions, retention, margins, and risk that this simple model does not capture. Two similar companies can be valued very differently depending on timing and buyer. It is a starting point for discussion.
- Does profitability or growth matter more?
- Historically growth dominated SaaS valuations, but in tighter markets profitability and efficient growth (a strong Rule of 40, good net revenue retention) carry more weight. The balance shifts with the funding environment.
- Is this financial advice?
- No. It is an informational estimate. For a real valuation, use current market comparables and professional advisors.
