How To Calculate Geometric Rate Of Return?

What is the geometric average rate of return?

The geometric mean, sometimes referred to as compounded annual growth rate or time-weighted rate of return, is the average rate of return of a set of values calculated using the products of the terms. What does that mean? Geometric mean takes several values and multiplies them together and sets them to the 1/nth power.

How geometric mean is calculated?

Geometric Mean Definition
Basically, we multiply the ‘n’ values altogether and take out the nth root of the numbers, where n is the total number of values. For example: for a given set of two numbers such as 8 and 1, the geometric mean is equal to √(8×1) = √8 = 2√2.

Can you calculate geometric mean in Excel?

For example, in Microsoft Excel™ the simple function “GeoMean” is provided to calculate the geometric mean of a series of data. For example, if you had 11 values in the range A1…A10, you would simply write this formula in any empty cell: ‘=geomean(A1:A10)’.

Can you calculate geometric mean with negative numbers?

Like zero, it is impossible to calculate Geometric Mean with negative numbers. However, there are several work-arounds for this problem, all of which require that the negative values be converted or transformed to a meaningful positive equivalent value.

How do you find the weighted geometric mean in Excel?

To figure out the weighted geometric mean, follow these steps:

  1. Compute the value of each Xi with an exponent equal to its weight wi:
  2. Multiply these results together:
  3. Divide 1 by the sum of the weights:
  4. Combine these results to find the weighted geometric mean:

How do you find the geometric mean example?

Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √(3×1) = √3 = 1.732.

How do you find the geometric mean percentage?

To do this, we add one to each number (to avoid any problems with negative percentages). Then, multiply all the numbers together and raise their product to the power of one divided by the count of the numbers in the series. Then, we subtract one from the result.

What is the difference between arithmetic and geometric averages?

Geometric mean is the calculation of mean or average of series of values of product which takes into account the effect of compounding and it is used for determining the performance of investment whereas arithmetic mean is the calculation of mean by sum of total of values divided by number of values.

How do you calculate weighted harmonic mean?

The general formula for calculating a harmonic mean is:

  1. Harmonic mean = n / (∑1/x_i)
  2. Weighted Harmonic Mean = (∑w_i ) / (∑w_i/x_i)
  3. P/E (Index) = (0.4+0.6) / (0.4/50 + 0.6/4) = 6.33.
  4. P/E (Index) = 0.4×50 + 0.6×4 = 22.4.

How do you calculate weighted average gross margin?

Calculate the weighted gross margin for all products sold by the company. Multiply each products gross profit margin by that product’s percentage of total sales. Continuing the same example, 75 percent x 25 percent = 18.75 percent. Repeat for each product sold by the company.

How do you find the geometric mean of 5 numbers?

Example: What is the Geometric Mean of 1, 3, 9, 27 and 81?

  1. First we multiply them: 1 × 3 × 9 × 27 × 81 = 59049.
  2. Then (as there are 5 numbers) take the 5th root: 5√59049 = 9.

What is the geometric mean between 4 and 25?

10
So, the geometric mean of 4 and 25 is 10.

What is the geometric mean between 4 and 6?

Equal Ratios
The ratio of the first number (4) and the geometric mean (6) is 4/6, which reduces to 2/3. The ratio of the second number (9) and the geometric mean (6) is 6/9, which reduces to 2/3.
