Stock Valuation Ratios Calculator

Computes the common per-share valuation ratios of a stock from its price and fundamentals: price-to-earnings and earnings yield, price-to-book, price-to-sales, dividend yield and payout ratio, PEG and EV/EBITDA, each only when its inputs are supplied.

When to use

You have a share price and per-share fundamentals and want the standard multiples to compare a stock with peers or its own history.

Do not use when: You want an intrinsic value from cash flows or dividends (use dcf-valuation or gordon-growth) or a dividend income projection (use dividend-yield). Informational only; not financial advice.

Formula

pe = share_price / earnings_per_share; earnings_yield = 100 / pe; pb = share_price / book_value_per_share; ps = share_price / sales_per_share; dividend_yield = dividend_per_share / share_price × 100; payout = dividend_per_share / earnings_per_share × 100; peg = pe / earnings_growth_percent; ev_to_ebitda = enterprise_value / ebitda

Plain multiples with no adjustments; use trailing or forward figures consistently (a forward P/E with trailing growth gives an inconsistent PEG). Informational mathematics only; not financial advice.

Example

Price 50, EPS 2.5, book value 20, dividend 1: {"share_price":50,"earnings_per_share":2.5,"book_value_per_share":20,"dividend_per_share":1} → {"pe_ratio":20,"earnings_yield_percent":5,"pb_ratio":2.5,"dividend_yield_percent":2,"payout_ratio_percent":40}

Price 120, EPS 4, growth 15 %, book 30, sales 60, EV 9 bn, EBITDA 600 M: {"share_price":120,"earnings_per_share":4,"earnings_growth_percent":15,"book_value_per_share":30,"sales_per_share":60,"enterprise_value":9000000000,"ebitda":600000000} → {"pe_ratio":30,"earnings_yield_percent":3.33,"peg_ratio":2,"pb_ratio":4,"ps_ratio":2,"ev_to_ebitda":15}

FAQ

Why is there no P/E for a loss-making company?

A negative P/E has no useful meaning, so it is omitted; the earnings yield is still reported as a negative percentage and P/S or EV/EBITDA can be used instead.

How is the PEG ratio read?

It divides the P/E by the growth rate in percent: a P/E of 30 with 15 % growth gives 2. Values around 1 are often taken as growth-adjusted fair value, though the rule is a heuristic.
