Economists and investors often refer to stock market growth and talk about the S&P 500 CAGR.

But what is S&P 500?

The S&P 500 Index is an index composed of the 500 largest companies that are listed on the stock market in the United States.

The stocks in the S&P 500 Index are weighted proportional to the market capitalization of the stocks.

The acronym “S&P” represents “Standard and Poor’s”, which originated from the amalgamation of Henry Poor’s annual book, which listed publicly held railroad companies, with the Standard Statistics Company’s publications in 1941.

The S&P 500 Index came into being in 1957. The “500” in the S&P 500 index refers to the number of stocks that are included in the index.

Some of the main stocks that constitute the S&P 500 Index are Apple (AAPL), Microsoft (MSFT), Alphabet(GOOG), Amazon (AMZN), Nvidia (NVDA), Exxon (XOM), etc.

The S&P 500 Index is maintained by the S&P Dow Jones Indices, a division of S&P Global.

## S&P 500 Average Return: How To Calculate S&P 500 CAGR?

Calculating the S&P 500 CAGR is easy, simply follow the steps below:

### Step 1.

Go to Yahoo Finance or Google Finance and search for S&P 500 in the search bar.

On Yahoo Finance, pick the first result, S&P 500, with the symbol ‘^GSPC’.

On Google Finance, pick the first result, S&P 500, with the symbol ‘.INX : INDEXSP’

### Step 2.

On Yahoo Finance make the chart fullscreen by clicking on the option above the chart.

In case of old-style Yahoo Finance charts, you will see a date range picker on top of the chart.

In case you get the new chart style, the date picker may be located at the bottom of the chart.

In either case, simply pick a date range you’d like.

Right next to it is the ‘Interval’. Pick the interval you’d like on your chart i.e. every data point on the chart should represent a day, week, month, etc.

Google Finance doesn’t allow the users to specify a particular date range, other than the predefined ranges it has – 1 day, 5 days, 1 month, 6 months, Year To Date, 1 Year, 5 Years, and MAX (which goes back to a maximum of 30 years).

You can pick a date range and hover over the chart to note down the date and values on Google Finance and skip to Step 4.

However, since Yahoo Finance allows more flexibility, we tend to use it more often.

### Step 3.

Once you have the chart adjusted for your date ranges, hover over the chart, note down the starting date, and the closing value.

You know the current date, the current value can be obtained by hovering over the chart or simply looking at the top section.

### Step 4.

Now you have the starting value (917), ending value (4135), and the time period (20 years). Feed these values in the CAGR Calculator fields – initial amount, final amount, and years respectively. Hit Calculate CAGR, and you have your S&P 500 CAGR!
