In this article, we’re going to explore how to calculate stock price using a variety of ways including from:

- market cap (aka market capitalization)
- the PE ratio (and other ‘Multiples’)
- dividends, and
- free cash flow

Let’s get into it!

## How to Calculate Stock Price

Before we get into the specifics of how to calculate stock price though, let’s be clear on *what *the stock price is.

### What is Stock Price?

Stock price refers to the current market price of a stock or share. It’s the price at which the stock *trades* *at* in the stock market.

There are a variety of ways to calculate the stock price, so let’s now look at the different ways.

### How to Calculate Stock Price Based on Market Cap

We can calculate the stock price by simply dividing the market cap by the number of shares outstanding.

In other words, we can stay that the Stock Price is calculated as…

Let’s now think about *why* we can calculate it this way.

The Market Cap (aka Market Capitalization) reflects the market value of the *equity* of the company. It’s calculated as…

Where refers to the Stock Price, and reflects the total number of shares outstanding.

We can rearrange the equation for market cap to obtain an expression for the stock price.

This is done by dividing both sides of the equation by , resulting in…

Okay, so you now know how to calculate stock price based on market cap. Let’s now consider a different approach and explore how to calculate share price using the PE ratio and other Multiples.

### How to Calculate Stock Price from PE Ratio (and other Multiples)

Described as the “investor’s darling ratio”, the PE ratio (or Price to Earnings Ratio) is one of the most popular investor ratios. The PE ratio is calculated as…

Where reflects the stock price and reflects the Earnings Per Share.

Using a similar approach we took when we learned how to calculate stock price based on market cap, we can rearrange the PE ratio equation to obtain an expression for the stock price.

This is done by *multiplying* both sides by the so that we have…

The same holds for other Multiples or ratios. For example, if we think about how to calculate stock price based on revenue multiples, we’d start by identifying a relevant revenue-based financial ratio.

Let’s consider the Price to Sales ratio (PS Ratio), estimated as…

Here reflects the stock price as before and displays the *Revenue Per Share*.

We can now rearrange the PS ratio to obtain an expression for the stock price as…

How did we get this? By simply multiplying both sides of the PS Ratio formula by the .

This approach to calculate share price is actually applying multiples for valuation, which is one of the 3 main ways of conducting stock valuation.

### How to Calculate Stock Price from Dividends

In addition to price-based multiples, we can also use dividend ratios and rearrange them to obtain an expression for the stock price.

Take the dividend yield for example. It’s calculated as follows…

Where and reflect the *Dividend Per Share*, and as before, represents the stock price.

Here again, the approach on how to calculate stock price from dividends is pretty similar to the approaches we’ve seen earlier.

Fundamentally, it’s just a simple case of rearranging the equation.

In this case, we can rearrange the equation to get the stock price formula as…

Incidentally, this equation is actually similar to the (famous) Dividend Discount Model (DDM)!

The Dividend Discount Model (DDM) in its simplest form, expresses the price of a stock as…

Here refers to the dividend per share, as above. And refers to the *cost of equity*.

And while there are many ways of estimating the cost of equity, for example, by using the Capital Asset Pricing Model (CAPM), it can also be proxied by the dividend yield.

Put differently, the dividend yield can be seen as an appropriate measure of the cost of equity. In other words…

And since the cost of equity is one appropriate discount rate, we can also think of the Dividend Yield as an appropriate discount rate!

Importantly, this is just *one** way* to estimate the cost of equity.

It’s not the *only way* by any means.

One other way is to use the CAPM (as stated above). In fact, we use the CAPM in our own Cost of Equity Calculator.

There are other ways to estimate the cost of equity, and we cover these extensively in our Definitive Guide to the Cost of Equity.

For now, let’s think about how to calculate stock price from Free Cash Flow to Equity.

### How to Calculate Stock Price From Free Cash Flow To Equity

In the “realm of cash flows”, there are broadly 2 kinds, including:

- Free Cash Flow (FCF), and
- Free Cash Flow to Equity (FCFE) (aka “flow to equity”, “FTE”)

Note that this is ignoring the Accountant’s perspective on the kinds of cash flows, which would usually be:

- Operating cash flows
- Investing cash flows
- Financing cash flows

While Free Cash Flow (FCF) is cash flow that’s *freely distributable* to debt *as well as *equity investors, FCFE is cash flow that’s *freely distributable* to equity investors exclusively.

It’s very common for Discounted Cash Flow (DCF) valuation models to work with free cash flow and free cash flow to equity.

If you’re looking to estimate the stock price from free cash flow, then you’re probably better off using FCFE.

That’s because, again, FCFE relates exclusively to equity investors, whereas FCF relates to both debt as well as equity investors.

Debt is largely irrelevant in the context of how to calculate share price. Debt is very relevant when calculating the value of the *firm* (aka, the value of the company).

And yes, the value of the *company* is not necessarily equal to the value of *equity*.

Remember, stocks are *equity instruments. *So you’ll ideally want to work with an equity-related cash flow.

You *can* also estimate the stock price using free cash flow, but you’ll need to make further adjustments and corrections in the model.

Essentially, you’ll need to subtract or remove the debt from your estimate of the company to get to an estimate for the equity.

And you’ll then take that equity estimate as your core proxy to estimate the stock price.

In a nutshell, though, you can calculate stock price from free cash flow to equity as follows:

Note that this share price formula is a *somewhat* simplified approach in that it implicitly assumes that the free cash flow remains constant indefinitely.

#### How to Calculate Share Price With Non-Constant Free Cash Flow To Equity

If you’d rather not make the assumption of constant free cash flow, then you could write out the formula for the stock price using FCFE as…

As complicated as this might look, it’s actually pretty straightforward.

Rather than working with a single, constant FCFE, we can now work with different FCFEs at different times.

If you were to open up the share price formula above, you’d have…

## Calculating the “Correct” Stock Price

One might argue that this share price calculation (using FCFE) allows an investor to get to a “better” estimate for the intrinsic value of a stock.

But that’s not necessarily true.

At the end of the day, valuation is subjective, and both context and preference dependent.

We share more about this idea in our video on ‘Introduction to Valuation’, viewable here:

## Wrapping Up

Hopefully, you now know how to calculate stock price quickly and easily.

Note that there is in fact a lot more to it than what we’ve shown.

For example, how do you know what the “right” free cash flow to equity value is? Or what the “correct” dividend value is?

And indeed, how do you know what the correct cost of equity is?

These are interesting and important questions. And the truth is, there’s no single correct answer to these questions. But it’s important to ask these questions nevertheless.
