how to calculate geometric mean of returns. Geometric mean return is a more complicated method of calculating the average rate but its more accurate than the arithmetic one. The geometric mean can be used to calculate average rates of return in finances or show how much something has grown over a specific period of time.
Geometric mean return is a more complicated method of calculating the average rate but its more accurate than the arithmetic one. In the light of equation 1 we can arrive at. Times 1 r_n - 1.
In other words it is the average return of an investment over time a metric used to evaluate the performance of a single investment or an investment portfolio.
The geometric mean is. This is equivalent to raising 19500 to the 15-th power. The GEOMEAN function calculates the geometric mean of a set of numbers by returning the nth root of n numbers. Hence the Geomean of 30000 and 33000 is calculated as.
