Stock Valuation Calculator
Estimates a stock's intrinsic value by blending the Gordon Growth dividend discount model with a P/E earnings approach. Use it to identify potentially overvalued or undervalued stocks.
About this calculator
This calculator combines two classic valuation methods. The Gordon Growth Model (DDM) values a stock based on its future dividends: DDM value = [currentDividend × (1 + g)] / (r − g), where g = dividendGrowthRate/100 and r = requiredReturn/100. The P/E approach values the stock as currentEPS × industryPE. The final blended intrinsic value = DDM value × 0.6 + P/E value × 0.4. The 60/40 weighting gives greater emphasis to dividend income (suitable for income-oriented stocks) while anchoring the estimate with earnings-based market comparables. If the intrinsic value exceeds the current market price, the stock may be undervalued; if it is lower, the stock may be overpriced relative to fundamentals.
How to use
A stock pays a $2.00 annual dividend growing at 4%, earnings per share are $3.50, the industry P/E is 18x, and your required return is 9%. DDM value = [2.00 × 1.04] / (0.09 − 0.04) = 2.08 / 0.05 = $41.60. P/E value = 3.50 × 18 = $63.00. Blended intrinsic value = 41.60 × 0.6 + 63.00 × 0.4 = $24.96 + $25.20 = $50.16. If the stock trades below $50.16, it may represent good value.
Frequently asked questions
What is the Gordon Growth Model and when should I use it for stock valuation?
The Gordon Growth Model (GGM) assumes a stock's value equals the present value of all future dividends growing at a constant rate: Value = D₁ / (r − g). It works best for mature, stable companies that pay consistent and predictably growing dividends, such as utility or consumer-staples stocks. It is less reliable for growth companies that pay no dividend or for firms with erratic earnings. The model is highly sensitive to the assumed growth rate — small changes in g can dramatically shift the valuation.
How does the required rate of return affect intrinsic stock value?
The required return (r) is the denominator driver in the DDM formula. A higher required return — which reflects higher perceived risk or rising interest rates — reduces the present value of future dividends, lowering the intrinsic value. Conversely, in a low-rate environment, the same dividend stream is worth more, pushing valuations up. This is why rising interest rates typically put downward pressure on dividend-paying stocks and bond proxies.
Why blend the dividend discount model with a P/E valuation?
Each method has blind spots: the DDM ignores companies that don't pay dividends and is sensitive to growth-rate assumptions, while P/E multiples vary across market cycles and can be distorted by accounting choices. Blending the two provides a more balanced estimate anchored in both income fundamentals and market-based earnings comparables. The 60/40 DDM-to-P/E weighting in this calculator tilts toward income investors but still uses the P/E component as a reality check against current market pricing.
