The S&P 500 closed on Friday at 1,335. By my calculations I also have as Reported Earnings (using a combination of actual and estimated earnings) at $92.33. Combining these two pieces of data gives us an S&P 500 P/E Ratio of 14.5.
While interesting, for my own investment purposes, I do not use the P/E ratio. Instead I use what I have called the Shiller PE10 which is shown in my first chart (effectively an S&P 500 cyclically adjusted PE or CAPE for short). This method is used and was made famous by Professor Robert Shiller. It is simply the ratio of Real (ie after inflation) S&P 500 Monthly Prices to 10 Year Real (ie after inflation) Average Earnings.
