Intrinsic Value Calculator

The intrinsic value calculator estimates a per-share value for a stock from earnings per share, expected growth, the current AAA corporate bond yield, and the current market price. In finance, intrinsic value often means a discounted cash flow or dividend discount estimate of fair value. This specific calculator, however, follows the earnings-based Graham-style formula implemented in the form: it multiplies EPS by a growth multiplier and adjusts the result for the bond-yield environment. That makes the page useful as a transparent value-investing screen rather than a complete DCF model.

Use the result to ask whether the price looks demanding or modest under your assumptions. If the estimate is far above the market quote, the calculator will show a positive margin of safety and upside to value. If the estimate is below the market quote, the stock may need stronger growth, lower risk, or better quality than the simple formula captures. Informational, not investment advice.

Inputs to use

Earnings per share should be trailing twelve-month EPS, recent annual EPS, or a normalized EPS figure if one unusual year would distort the analysis. A cyclical manufacturer at peak margins may deserve a lower normalized EPS, while a temporarily depressed company may need an average across a full cycle. The form allows zero EPS, but a zero input produces a zero value, zero margin of safety, and no useful buy signal.

Expected annual growth is entered as a percentage, not a decimal. Type 8 for eight percent. The formula uses the number directly in the multiplier, so moving from six to eight does not merely add two percentage points; it adds four points to the Graham growth multiplier because the formula uses two times growth. Keep that sensitivity in mind.

AAA corporate bond yield is also entered as a percentage. The default is 4.4, matching the historical benchmark in the formula. If you enter 5.5, the estimate falls because the 4.4 over yield adjustment is smaller. If you enter 3.5, the estimate rises. Current market price is used only for comparison metrics: margin of safety, upside or downside to value, and market price as a percentage of value.

Formula

The calculator first computes the Graham growth multiplier:

$\text{growth multiplier} = 8.5 + 2 \times \text{growth rate}$

Then it estimates value per share:

$\text{intrinsic value} = \text{EPS} \times \text{growth multiplier} \times \frac{4.4}{\text{AAA yield}}$

The comparison outputs use the same value:

$\text{margin of safety} = \frac{\text{intrinsic value} - \text{market price}}{\text{intrinsic value}} \times 100\%$

$\text{upside or downside} = \frac{\text{intrinsic value} - \text{market price}}{\text{market price}} \times 100\%$

Worked example

Suppose EPS is $5.00, expected growth is 8, the AAA corporate bond yield is 4.4, and the market price is $95.00. The growth multiplier is 8.5 plus two times 8, or 24.5. Because the bond-yield adjustment is 4.4 divided by 4.4, it equals 1.00. Intrinsic value is therefore $5.00 times 24.5 times 1.00, which equals $122.50 per share.

The margin of safety is the value minus price, divided by value: $122.50 minus $95.00 equals $27.50, and $27.50 divided by $122.50 equals 22.45 percent. Upside or downside to value uses the market price as the denominator: $27.50 divided by $95.00 equals 28.95 percent. Market price as value is $95.00 divided by $122.50, or 77.55 percent. Those numbers match the default calculation in the form.

Change only the bond yield to 5.0 and the value becomes $5.00 times 24.5 times 4.4 divided by 5.0, or $107.80. The same company suddenly has less apparent upside because investors can earn more from safer bonds. Change only growth to 6 and the multiplier becomes 20.5, making the value $102.50 at a 4.4 yield. The example shows why growth and yield assumptions deserve more attention than the final rounded dollar figure.

How investors use the result

This calculation is best used before deeper research. A positive screen can justify reading the latest annual report, studying debt maturities, comparing margins with peers, or building a full DCF. A negative screen can save time by showing that the current price already assumes strong earnings power. To model time value more directly, compare this page with the present value annuity calculator. To see how a return compounds after purchase, use the compound interest calculator. To compare a projected sale price with your cost basis, use the ROI calculator.

Keep the denominator of the margin of safety in mind. This calculator divides by estimated value, not by market price. The upside or downside output divides by market price. Both are useful, but they answer different questions: one measures cushion relative to value, while the other measures potential return relative to today’s quote.

Limitations and tips

The formula depends on accounting EPS, so it can be distorted by buybacks, write-offs, tax items, acquisitions, and temporary margins. It does not subtract debt directly, project reinvestment, separate operating cash flow from accrual earnings, or model terminal value. It also treats the growth estimate as a single stable input, even though real businesses grow unevenly.

Use normalized EPS for cyclical firms, cap growth at a rate the company can sustain, and rerun the calculation with a higher bond yield to see how fragile the conclusion is. If the stock only looks cheap under optimistic inputs, the margin of safety is probably not real. If it remains reasonably priced under conservative inputs, it may deserve a more detailed valuation model.
