Discovering the realized rate of return, also known as the real rate of return or ROR, can help investors make better-informed decisions. The ROR represents the return on an investment adjusted for factors such as inflation during a stated period. In other words, it can give you a more accurate idea of how much money your money is really making. To calculate the realized rate of return online, you need the nominal rate of return, such as the investment's interest rate, and the inflation rate.

#### Tips

To arrive at the inflation rate for a given year-long period, find the Consumer Price Index, an index published monthly by the Bureau of Labor Statistics, for the start and end of the period under review. For example, to discover the inflation rate for the period from June 2010 to June 2011, deduct the consumer price index of June 2010 from the index of June 2011. Then divide the result by the June 2011 rate. Multiply that figure by 100 to arrive at a percentage. For example, if last year's index was 100 and this year's is 120, the calculation would be 120 minus 100 equals 20. The figure 20 divided by 100 equals 0.2. 0.2 times 100 equals 20 percent.
