What Is the EPS Formula? We Break it Down!

Written by Tim Bohen

When you’re trading or investing, you need to research every company that’s a potential trade.

Chart patterns and news catalysts are always necessary, but understanding the financial health of a company can also be a crucial step in weeding out less-than-stellar opportunities.

So how do you analyze a company’s financial health? Fundamental analysis. And don’t worry, you don’t need special accounting or math skills. It’s all pretty simple.

Today we’ll cover one of the most common fundamental ratios used in the markets: the earnings per share (EPS) ratio. Yawn, right? Wrong! This is an important piece of the puzzle …

You can use the EPS ratio to determine how much a company makes for its shareholders. You can then see if the company’s improving and even compare it to its competitors.

It’s all about your research and making more educated buying or selling decisions. Let’s get down to it!

The EPS Formula

First, let’s clearly define what exactly the EPS formula is.

Earnings per share (EPS) is a financial ratio. It’s how much a company makes (its earnings) divided by the number of the company’s shares. Traders then use this ratio to analyze the company’s ability to produce profits for shareholders.

On its own, the EPS ratio doesn’t mean a great deal to a trader. Like we said, it’s a piece of the puzzle. It’s often used along with other fundamental and technical analysis, giving traders a broad perspective of a stock’s health.

EPS Calculation Formula

Now, let’s learn how to calculate the EPS using a simple formula. Don’t worry if you suck at math — this formula is super easy.

Before we begin our calculation, we need two pieces of information:

First, we need to know the net income and stock dividend amount, which can be found on the income statement. This number is effectively how much money the company makes.

Second, we need to know the number of common shares outstanding. This is found on a section of the balance sheet under stockholders’ equity.

Now, subtract the dividends paid on preferred shares from the net income amount. That’s the company’s total earnings.

Next, divide the total earnings number by the number of outstanding shares.

Congratulations, you just calculated a company’s EPS!

Why the EPS Ratio Matters

The earnings per share metric is important to anyone evaluating a company’s financial health.

The number shows the company’s profits on a per-share basis. You can use it to track historical performance by comparing the EPS number over different years or quarters.

You may be wondering why you couldn’t just look at the company’s earnings … Why make things more complicated by calculating earnings per share?

The reason is that over time the number of shares in a company can change substantially. There can be buy-backs and new offerings.

That’s a big part of why calculating the EPS ratio matters. It gives traders a way to standardize the earnings number so they can compare apples with apples, regardless of a company’s size or structure changes.

Calculating the EPS formula is also a major step in some of the most common fundamental analysis techniques. If you analyze stocks, this is a very useful calculation to wrap your head around.

Here are a few fundamental analysis techniques that you’ll need the EPS for:

#1 P/E Ratio

The price-to-earnings (P/E) ratio is the most old-school, granddaddy formula for determining a company’s valuation.

This ratio measures a stock’s current share price against its earnings per share. It’s also another simple calculation. Divide the stock price by the earnings per share.

price earnings ratio

Once you determine the P/E ratio for one company, you can calculate this ratio for several other companies, allowing you to compare the rough valuation of each company. You can then use that information to help you determine your next move …

For example, you may look to buy breakouts in stocks with low P/Es.

Why? A stock with a low P/E is possibly undervalued and the stock’s breakout implies that the market’s catching on. That could result in the stock price rocketing up until it reaches its fundamental value.

But remember — it’s all about your trading style and a slew of other factors.

#2 Other Valuation Methods

The EPS number isn’t just used in the P/E ratio.

There are other company valuation methods as well, such as the capital asset pricing model (CAPM) and the dividend discount model (DDM). These valuation techniques are complicated and well beyond the scope of this post. Plus, as an active trader, you’ll likely never use them.

Instead, it’s important to understand how earnings, especially earnings per share, can affect how investors value a stock.

Investors can buy a stock with the goal of making a return over time by holding onto an asset that makes a profit. Pretty simple, right?

Now, imagine that the asset grows its income and starts earning double the amount of profit. It’s pretty easy to imagine that the value of that asset has increased, maybe even doubled …

So, just keep in mind that the amount a company earns often has a direct effect on the market’s perceived value of that stock.

#3 Comparing Different Stocks

Knowing a company’s EPS can give you a snapshot of its current profitability and is useful in determining the company’s financial health over time.

But another common way to use the ratio when analyzing companies is to compare the EPS between stocks in the same sector. For instance, an investor might compare the EPS numbers of Ford and General Motors.

These companies are clearly in the same market and clearly major competitors.

But what if Ford has a substantially higher EPS than General Motors? This could be a hint that Ford is a better run company and potentially a better investment long term. As an active trader, you might not be thinking in terms of long-term investments.

But it’s a great idea to understand that changes in the earnings (and therefore the EPS) can cause money to flow into and out of stocks (especially during reporting seasons).

It’s good to have this in the back of your mind when looking for trades.

Types of EPS

We hope you’re enjoying this master class in all things EPS.

By now, you should be comfortable calculating the EPS of a company and hopefully have some ideas on how to use it in your trading strategy.

Next up, let’s run through the various types of EPS.

There are three types that differ, depending on which time period you’re looking at. Let’s take a closer look …

Current EPS

Current EPS is what we’ve focused on so far in this post.

It’s a company’s current earnings per share, determined by how much the company is currently earning and how many shares are currently outstanding.

This is the most commonly used EPS ratio — it gives the most up-to-date information without any of the subjective elements often involved in estimating future numbers.

So, if you learn how to calculate only one type of EPS, the current EPS is the one to pick.

Trailing EPS

Calculating the trailing EPS can allow you to see how a company’s EPS changes over time.

You can calculate a company’s EPS using the earnings numbers from previous quarters, usually using the four most recent quarters. At the end of a quarter, you can then recalculate the EPS using the latest financial information.

This can help you to analyze the trend of a share’s EPS numbers and also get an idea of the direction of a company’s financial health.

If the earnings per share grows over time, you get the sense that the company is doing well, then look for chart patterns that show good potential to the long-side. It all depends on your specific trading strategy.

Here’s a good way to think of trailing EPS: It’s basically a moving average for a company’s earnings per share.

Forward EPS

Forward EPS is another version of EPS analysis. It involves making an estimation of a company’s upcoming earnings.

Here’s how to calculate the forward EPS: Divide the company’s current share price by the estimated future earnings per share.

Careful … this can get a little tricky. Calculating future earnings can be very difficult if you’re not an absolute expert on the company. Heck, even experts can completely miss the mark on potential future earnings.

The upside — if you can do it correctly — is that you can spot a major change before the market. It’s that whole early-bird notion.

Big caveat: Average traders should be wary of trying to estimate the future earnings of a stock, but it’s important to know about this technique.

Using a Stock Scanner for EPS, P/E, and Other Analysis
