Formula and methodology
Formula: Graham number = √(22.5 × EPS × book value per share), where 22.5 is the product of the classic 15 earnings multiple and 1.5 price-to-book factor.
The Graham number is a compact historical screening heuristic that combines earnings per share and book value per share. This page exposes the inputs and the implied ratios at the returned screening value so the result is easier to audit. It is not a forecast, an intrinsic-value proof, a market price target, or a substitute for current financial statements and a broader analysis.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Earnings per share (EPS) — currency/share; minimum 1.0E-6; maximum 1000000
- Book value per share — currency/share; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Earnings per share (EPS) | 5 |
| Book value per share | 40 |
Graham number = √(22.5 × 5 × 40) ≈ 67.08 currency units per share.
Assumptions and limits
- EPS and book value per share are positive, current-period-compatible figures expressed in the same currency per share.
- The constant 22.5 is treated as the classic 15× earnings and 1.5× book-value screening convention.
- The calculation ignores growth, debt, cash flow, asset quality, dilution, cyclicality, interest rates, industry differences, and market conditions.
- Book value can differ materially from economic value, especially for intangible-heavy or rapidly changing businesses.
- The output is a screening heuristic and should not be presented as a fair value or personalized investment recommendation.
- Use verified financial statements and independent research before making any financial decision.
