Stock Return/Purchase Date Calculator - See How Buying Low Affects Returns

Use the calculator to see how buy-and-hold investing has performed for a specified investing period for any stock listed on a major U.S. stock exchange and supported by Quandl.

The calculator displays a chart of percent returns for a selected period for a given stock highlighting the profitable investment dates in green and the unprofitable ones in red.

The chart shows the percent return of each buy-and-hold investment for a period of purchase dates that you specify on the input form below. The percent return for each purchase date is computed using the following formula:

Percent return = ((Today's closing price - Purchase date closing price) / Purchase date closing price) * 100

The calculator assumes that the stock has been held since the purchase date so the percent return is valued as of the most current closing price.
