Intrinsic Value Calculator

Estimate a stock's intrinsic value using DCF, Dividend Discount Model, and Graham formulas. Includes margin of safety, sensitivity table, and multi-model comparison.

About the Intrinsic Value Calculator

Intrinsic value is the estimated true worth of a stock based on its fundamentals — earnings, growth, dividends, and assets — independent of its current market price. Comparing intrinsic value to market price is the foundation of value investing, as popularized by Benjamin Graham and Warren Buffett.

This calculator offers four valuation models: Discounted Earnings (a simplified DCF), the Dividend Discount Model (Gordon Growth), the Graham Formula, and the Graham Number. Each model approaches valuation from a different angle, and comparing results across models provides a more robust estimate than relying on any single method.

The margin of safety — the gap between intrinsic value and current price — is your cushion against estimation errors. A margin above 20-30% is generally recommended. The sensitivity table shows how changes in discount rate and growth rate assumptions affect the valuation, revealing which assumptions matter most. Use it to test how much the estimate moves when growth or discount assumptions change.

Why Use This Intrinsic Value Calculator?

Use this when you want a disciplined estimate of what a business is worth before buying shares or setting a target price. It helps compare optimistic and conservative assumptions, and it makes the margin of safety explicit so you can judge whether the stock price already reflects the business's fundamentals.

How to Use This Calculator

  1. Select a valuation model (DCF, DDM, Graham, or Graham Number).
  2. Enter the current EPS and expected growth rate.
  3. Set your required rate of return (discount rate).
  4. Add terminal growth rate and projection period for DCF.
  5. Enter the current stock price to see margin of safety.
  6. Check the sensitivity table to assess how assumption changes affect the value.

Formula

DCF = Σ(EPS × (1+g)^t / (1+r)^t) + Terminal Value / (1+r)^n DDM = D₁ / (r − g) where D₁ = current dividend × (1+g) Graham = EPS × (8.5 + 2g) × 4.4/Y Graham Number = √(22.5 × EPS × Book Value)

Example Calculation

Result: Intrinsic Value ≈ $115

Projecting $5 EPS growing at 8% for 10 years, discounted at 10% with 3% terminal growth, yields an intrinsic value of approximately $115. At a stock price of $85, that's a 26% margin of safety.

Tips & Best Practices

How the Models Differ

Discounted earnings is the most direct forecast-based approach, while DDM is best for companies that return cash through dividends. The Graham methods are more conservative and work as a quick valuation check when you want a second opinion on the result.

Interpreting the Output

If the model values cluster together, the estimate is more defensible. If one model is far outside the others, inspect the assumptions behind it first: growth rate, discount rate, dividend growth, or book value. The sensitivity table is most useful when the market price sits near your fair-value range.

Methodology

This worksheet compares four valuation frameworks: a discounted-earnings model, a Gordon-style dividend-discount model, the Graham formula, and the Graham Number. It uses the growth, discount, terminal-growth, EPS, dividend, and book-value inputs entered on the page to produce a valuation range and then compares that range to the current stock price through a margin-of-safety lens.

The result is a scenario-based estimate rather than a market quote or a full operating model. The discounted-earnings model on this page is simpler than a full free-cash-flow DCF, so the output is best used as a valuation cross-check and entry-price worksheet instead of a stand-alone investment recommendation.

Frequently Asked Questions

What discount rate should I use?

Use your required rate of return — typically 8-12%. Higher rates give more conservative (lower) valuations. CAPM or WACC can provide a systematic rate.

Why do different models give different values?

Each model captures different aspects of value. DCF values earnings power, DDM values dividend cash flows, and Graham methods emphasize asset backing. The range provides a valuation zone.

What is a good margin of safety?

Graham recommended 30%+. Buffett targets 25%+ for stable businesses and 40%+ for uncertain ones. Higher margins compensate for estimation risk.

When should I use DDM vs DCF?

Use DDM for stable dividend-paying companies. Use DCF for growth companies that reinvest earnings rather than paying dividends.

What terminal growth rate is appropriate?

Terminal growth should not exceed the long-term GDP growth rate (2-3%). Higher rates imply the company grows faster than the economy forever, which is unsustainable.

How reliable is intrinsic value?

It's an estimate, not a precise number. The sensitivity table shows how ±2% changes in assumptions can swing the value significantly. Use it as a guide, not a guarantee.
