Gellidus,
Yes, I think Graham Number is Benjamin Graham's idea of the Fair Price of a share of stock.
Benjamin Graham actually defined 2 metrics help determine if a stock was a good value or not.
The first, was Graham Number (which this post thread has been discussing):
Graham number - fair value of stock
= SQRT( 22.5 x EPS x BVPS )
EPS - Earnings per Share (for last year)
BVPS - Book Value per Share (as of most recent quarter)
(If I am calculating EPS and BVPS from other numbers, I only use shares of common stock & not preferred stock).
The other:
Graham Intrinsic Value (also called "
Benjamin Graham Formula") - stock's value including time growth
= (EPS x (8.5 + (2 x 5 yr growth rate)) x 4.40 / (20 yr AAA corporate bond rate)
EPS - Earnings per Share (common + preferred)
8.5 - Typical PE ratio for a non-growth company
4.4 - Yield of corporate AAA bonds in 1962 (when model introduced)
Current 20 year AAA corporate bond rate - Available at:

(I calculate Graham Intrinsic Value both without and with dividends. To calculate Graham Intrinsic Value "Total Return" (with dividends), I add the yearly dividend yield to the yearly predicted growth rate).
You can look up both "Graham Number" and "Benjamin Graham Formula" on Wikipedia which gives a good summary of both.
I hope this helps.
