Valuation Multiples Explained for Everyday Investors
A share price by itself means nothing — a $50 stock isn't "cheaper" than a $200 one. Valuation multiples fix that by comparing price (or whole-company value) to a financial measure like earnings, sales, or cash flow. They turn a raw number into something you can compare across companies and time.
The common multiples at a glance
| Multiple | Formula | What it values | Best used when… |
|---|---|---|---|
| P/E | Price ÷ EPS | Profit to shareholders | Company is steadily profitable |
| P/S | Price ÷ Sales/share | Revenue generation | Earnings are weak, negative, or volatile |
| EV/EBITDA | Enterprise value ÷ EBITDA | Whole business vs. operating earnings | Comparing firms with different debt levels |
| P/B | Price ÷ Book value/share | Net asset value | Asset-heavy firms (banks, insurers) |
| P/FCF | Price ÷ free cash flow/share | Cash actually produced | You want a cash-based sanity check |
Why "enterprise value" appears in EV/EBITDA
Market cap only counts the equity. Enterprise value (EV) is what it would cost to buy the whole business — equity plus debt, minus the cash you'd inherit. That's why EV/EBITDA compares fairly across companies with different borrowing.
Worked example: pick the right lens
The same three companies look very different depending on which multiple you use — which is the point.
| Company | Profitable? | Debt? | Most useful multiple |
|---|---|---|---|
| Mature consumer brand | Yes, stable | Low | P/E or P/FCF |
| Fast-growing, not yet profitable | No (reinvesting) | Low | P/S (earnings aren't meaningful yet) |
| Leveraged industrial | Yes | High | EV/EBITDA (neutralizes debt) |
How to use multiples without getting fooled
| Do | Avoid |
|---|---|
| Compare a company to its own history | Treating "low multiple = cheap" as a rule |
| Compare to close peers in the same industry | Comparing unrelated industries head-to-head |
| Pair the multiple with growth & margins | Using one quarter's distorted number |
| Ask why a multiple is high or low | Assuming "high multiple = overpriced" |
A low multiple can reflect weak margins, poor growth, or balance-sheet stress; a high one can reflect durable advantages and high returns on capital. Multiples are a filter and a conversation starter — they point you toward better questions about quality, risk, and sustainability.
