Intrinsic Value Calculator

What intrinsic value represents

Intrinsic value attempts to answer a practical investing question: what is this stock actually worth under the assumptions I am willing to defend? If the market price is below intrinsic value, the stock may be undervalued. If the market price is above intrinsic value, the stock may be overvalued or the model may be too conservative.

Unlike market price, which reflects current supply, demand, liquidity, and sentiment, intrinsic value is derived from fundamental analysis. The inputs usually come from the company's earnings power, growth prospects, risk, capital needs, and the investor's required return.

This calculator is intentionally focused on an earnings-based intrinsic value model. Calcipedia also has separate DCF, Graham Number, and margin-of-safety calculators, so this page keeps the main workflow centered on EPS growth, terminal P/E, discounting, and price comparison instead of trying to duplicate every valuation method in one interface.

Earnings-based intrinsic value model

The model projects current earnings per share forward by an expected growth rate, applies a terminal P/E multiple at the end of the projection period, and discounts that future price back to present value. The result is a per-share fair value estimate that can be compared with the current market price.

This is a shortcut rather than a full discounted cash flow model. It can be useful when EPS is the clearest available input, but it still depends heavily on whether current earnings are normal, whether growth is realistic, and whether the terminal P/E multiple is appropriate for a mature version of the company.

The calculator now shows the future EPS, the implied future price, the present value, the price-to-intrinsic-value ratio, and the margin of safety. Those extra rows make the calculation easier to audit than a single unexplained fair-value number.

Worked example: EPS growth, terminal P/E, and present value

Suppose current EPS is 5.00, expected earnings growth is 10% per year for 10 years, the terminal P/E ratio is 15x, and the discount rate is 12%. Future EPS is 5.00 x 1.10^10, or about 12.97. Multiplying by the 15x terminal P/E gives a future price of about 194.53.

Discounting that future price back for 10 years at 12% gives an intrinsic value of roughly 62.61 per share. If the current market price is 45.00, the valuation gap is about 17.61 and the margin of safety is about 28%. That is a potentially useful cushion, but it only exists if the growth, multiple, and discount-rate assumptions are credible.

The preset scenarios are designed to make this kind of pressure test faster. A conservative case lowers growth and the terminal multiple. A growth case raises the growth assumption but also raises the discount rate to acknowledge higher risk. If a stock only looks attractive in the most optimistic case, the conclusion is fragile.

How to choose the inputs

Current EPS should usually be a normalized earnings figure rather than a one-off peak or trough. Cyclical companies, restructuring charges, large tax effects, accounting changes, and unusual gains can all make trailing EPS a poor base year for valuation. Review the income statement, management discussion, and recent filings before treating EPS as stable.

Expected growth should be tied to realistic business drivers: revenue growth, margin durability, reinvestment opportunities, competitive position, and dilution. Very high growth rates become harder to defend as the projection period gets longer, so conservative users often test a lower-growth case even when the recent trend looks strong.

The discount rate is the required return you demand for owning the stock. Some investors use a cost-of-equity estimate, some use WACC for business-level DCF models, and some use a personal hurdle rate. Higher risk should generally mean a higher discount rate, which lowers intrinsic value.

The terminal P/E ratio should describe a more mature business, not just today's market enthusiasm. Compare the company's historical P/E range, peer multiples, return on capital, balance-sheet risk, and expected growth quality before choosing a terminal multiple.

Using the margin of safety

The margin of safety is the cushion between your estimate of intrinsic value and the current market price. A positive margin means the model value is above the market price. A negative margin means the market price is already above the model estimate.

A margin of safety is not proof that a stock is cheap. It is protection against being wrong. If your EPS, growth, discount-rate, or terminal P/E assumptions are too optimistic, the apparent discount can disappear quickly. That is why the result should be read together with the sensitivity range, not in isolation.

Use the value gap to frame follow-up research. If the calculator shows a large discount, ask what risk the market may already be pricing in. If it shows overvaluation, ask whether the company has durable growth, pricing power, net cash, or other qualities that the simplified earnings model does not capture.

Why sensitivity checks matter

Intrinsic value estimates are highly assumption-sensitive. A small increase in the discount rate can lower fair value, while a small increase in growth can raise it. Terminal multiple changes can also dominate the result because much of the final value comes from the price assigned at the end of the forecast period.

The sensitivity table reruns the same model with growth and discount rate shifted by two percentage points in each direction. If the low and high values are far apart, the stock may need a wider margin of safety before the estimate is decision-useful.

Sensitivity checks are especially important for growth stocks, turnarounds, cyclicals, and companies with unstable margins. In those cases, a full DCF, a Graham-style cross-check, and peer comparison may be more informative than relying on one earnings shortcut.

How this differs from DCF, Graham, and DDM models

A full DCF model usually forecasts free cash flow year by year, discounts each cash flow, adds a terminal value, adjusts for net debt, and divides by shares outstanding. This intrinsic value calculator is simpler: it uses EPS, growth, and a terminal P/E multiple to estimate a future price and then discounts that price back to today.

The Graham Formula and Graham Number are more conservative value-investing screens. They can be useful as second opinions, but they require different inputs such as book value per share, bond yields, or a Graham-specific growth formula. Dividend discount models are better suited to mature dividend-paying companies where dividends are the main cash return to shareholders.

The best workflow is usually comparative. Use this earnings-based calculator for a quick fair value estimate, then compare the answer with a DCF model, a Graham Number, a margin-of-safety target, peer multiples, and the company's own filings.

Why the Graham Formula cross-check is included

Many intrinsic value tools expose several valuation methods because no single shortcut is reliable across every business. The optional Graham Formula cross-check gives a second opinion using EPS, growth, and an AAA corporate bond yield assumption. It is intentionally shown next to the earnings terminal-P/E model rather than hidden as a separate black-box score.

A large difference between the two values is useful information. It may mean the terminal P/E assumption is too generous, the Graham growth input is too aggressive, current earnings are not normalized, or the company needs a sector-specific model. Treat the cross-check as a reason to investigate the assumptions, not as an automatic buy or sell signal.

Common mistakes when valuing a stock

The first mistake is using a single precise output as if it were a market truth. Intrinsic value is an estimate, not an observable fact. A better answer is usually a range supported by conservative, base, and optimistic cases.

The second mistake is mixing incompatible assumptions. A very high terminal P/E may be inconsistent with low long-term growth or weak returns on capital. A low discount rate may be inappropriate for a company with volatile earnings, heavy leverage, or uncertain cash conversion.

The third mistake is ignoring dilution, buybacks, dividends, debt, and reinvestment needs. EPS per share can improve because the share count falls, or it can be diluted by stock compensation and new issuance. A simplified earnings model cannot replace reading the company's filings and understanding how capital is actually allocated.
