What is ROI?

ROI or Return on Investment calculates the percentage gained or lost on an investment.

Enter the initial amount invested and the date the investment was made. Enter the total amount returned and the date. Click the 'Calc' button.

The results include the percentage gained or loss on the investment as well as the annualized gain or loss also expressed as a percent. The annualized return can be used to compare one investment with another investment.

Example: If you bought $25,000 worth of your favorite stock on January 2nd 2006 and sold it for $33,000 on June 30th 3007, you would have a gain of $8,000 which is 32%. The annualized gain is 21.5%.

Now, lets say you made a second investment on January 2nd, 2006. This time for $10,000 and you sold it for $11,000 on Feb. 1st, 2006. The gain is only $1,000 or 10%. However, annualized the gain is 117.8%. Ignoring risk (which can be very dangerous), one would generally consider the latter investment to be better than the former.
