Tool Documentation

Graham's Formula

Calculates the Intrinsic Value of a stock with the following formula:

Intrinsic Value = √(EPS × BVPS × Ideal_P/E × Ideal_P/BV)

  • Ideal P/E: Reference value for Price/Earnings (e.g., 15)
  • Ideal P/BV: Reference value for Price/Book Value (e.g., 1.5)
  • EPS: Earnings Per Share
  • BVPS: Book Value Per Share

Bazin's Method

Calculates the Ceiling Price of a stock based on the average dividend and the desired Dividend Yield:

Ceiling Price = Average Dividends Paid / (Desired Dividend Yield (%) / 100)

  • Desired Dividend Yield: Desired return percentage (e.g., 6%)
  • Average Dividends Paid: Annual average of dividends paid over the last 5 years.

Facts about the Fair Price Calculator

  • The Fair Price Calculator estimates the intrinsic value of stocks.
  • The calculation applies valuation methods based on the company's fundamentals.
  • The tool compares the market price with the estimated fair price.
  • The result is an educational estimate and does not constitute an investment recommendation.
