The price-to-sales (P/S) ratio is one of the most widely used valuation metrics for high-growth software and SaaS companies where earnings are not yet a reliable guide to value.
P/S Ratio = Market Capitalization ÷ Annual Revenue
Or equivalently: EV/Revenue = Enterprise Value ÷ Annual Revenue
For private companies, the numerator is the post-money valuation from the most recent funding round.
P/S Ratio Benchmarks by Stage (2024)
| Company Stage | Typical P/S Range | Notes |
|---|---|---|
| Early-stage SaaS (50%+ growth) | 8–20x ARR | Seed to Series A |
| Growth-stage SaaS (30–50% growth) | 5–12x ARR | Series B to C |
| Late-stage SaaS (20–30% growth) | 3–8x ARR | Pre-IPO |
| Public SaaS (10–20% growth) | 2–6x revenue | Median ~4x in 2024 |
| Declining / mature software | 0.5–2x revenue | PE buyout range |
After the 2021–2022 multiple compression, public SaaS P/S multiples fell from 20–30x to 4–8x as interest rates rose. The current (2024) median public SaaS P/S is approximately 4–6x forward revenue.
The Rule of 40 Connection
High P/S multiples are justified when the Rule of 40 score is strong. A company growing 50% with −5% FCF margin (Rule of 40 = 45%) trades at higher multiples than one growing 20% with −15% margin (Rule of 40 = 5%).
Growth-adjusted P/S = P/S ÷ Growth Rate
A P/S of 10x at 50% growth gives growth-adjusted P/S of 0.2x — often considered fair value. Above 0.3x can be stretched; below 0.15x can represent value.
EV/Revenue vs. P/S
For companies with debt or significant cash, Enterprise Value / Revenue is more accurate than P/S:
EV = Market Cap + Total Debt − Cash and Equivalents
Most early-stage startups have minimal debt and cash burning down, so EV ≈ Market Cap. For cash-rich companies or those with venture debt, the adjustment matters.
Frequently asked questions
What P/S ratio should I target for my startup valuation? At Series A, 8–15x ARR is common for SaaS companies growing 80%+. At Series B, 10–20x ARR for companies with strong NRR (120%+) and 50%+ growth. These numbers compress significantly as growth slows — a 30% grower typically gets 4–8x.
How do I use P/S for competitive benchmarking? Find 5–10 public comps with similar growth rates and business models. Take the median P/S. Apply it to your ARR for a rough valuation range. Discount 20–30% for private-company illiquidity premium. This is the most common method used by VC investors for Series B+ valuations.
