Average rate of return
To calculate the average rate of return on investment for a given number of periods, enter the rates
for the same periodicity. For example, annual, monthly, etc. Use the point as decimal separator.
If an investment in three years has got in the first year a gain of 10%, 20% in the second and the third a loss of 15%, enter: 10, 20 and -15. The correct result is 3.91%, calculated by the geometric mean, not 5%, calculated by the arithmetic mean.
This is the most appropriate way to calculate the average rate of return. Many people use the arithmetic mean instead geometric mean.
The results are automatically displayed after you click on "Calculate".
