What Is Average Return?

The average return is the simple mathematical average of a series of returns generated over a predefined period of time. An average return is calculated the same way that a simple average is calculated for any set of numbers. The numbers are added together into a single sum, then, at that point, the sum is partitioned by the count of the numbers in the set.

Figuring out Average Return

There are several return measures and ways of working out them. For the arithmetic average return, one takes the sum of the returns and partitions it by the number of return figures.
Average Return=Sum of ReturnsNumber of Returns\text = \dfrac{\text}{\text}
The average return tells an investor or analyst what the returns for a stock or security have been in the past, or what the returns of a portfolio of companies are. The average return isn't equivalent to an annualized return, as it disregards compounding.

Average Return Example

One illustration of average return is the simple arithmetic mean. For example, assume an investment returns the accompanying annually over a period of five full years: 10%, 15%, 10%, 0%, and 5%. To ascertain the average return for the investment over this five-year period, the five annual returns are added together and afterward isolated by 5. This creates an annual average return of 8%.

Presently, we should check out at a genuine model. Shares of Walmart returned 9.1% in 2014, lost 28.6% in 2015, acquired 12.8% in 2016, acquired 42.9% in 2017, and lost 5.7% in 2018. The average return of Walmart over those five years is 6.1%, or 30.5% partitioned by 5 years.

Ascertaining Returns From Growth

The simple growth rate is a function of the beginning and ending values or balances. It is calculated by deducting the ending value from the very start value and afterward separating by the beginning value. The formula is as per the following:
Growth¬†Rate=BV‚ąíEVBVwhere:BV=Beginning¬†ValueEV=Ending¬†Value\begin &\text = \dfrac{\text -\text}{\text}\ &\textbf\ &\text = \text\ &\text = \text\ \end
For instance, on the off chance that you invest $10,000 in a company and the stock price increments from $50 to $100, then the return can be calculated by taking the difference somewhere in the range of $100 and $50 and partitioning by $50. The response is 100%, and that means you currently have $20,000.

The simple average of returns is a simple calculation, however it isn't extremely accurate. For additional accurate calculations of returns, analysts and investors likewise every now and again utilize the geometric mean or the money-weighted rate of return.

Average Return Alternatives

Geometric Average

While taking a gander at average historical returns, the geometric average is a more exact calculation. The geometric mean is consistently below the average return. One benefit of utilizing the geometric mean is that the real sums invested need not be known. The calculation centers completely around the return figures themselves and presents logical comparison while checking out at least two investments' performances throughout more different time periods.

The geometric average return is sometimes called the time-weighted rate of return (TWR) on the grounds that it dispenses with the mutilating effects on growth rates made by different inflows and outflows of money into an account over the long haul.

Money-Weighted Rate of Return (MWRR)

On the other hand, the money-weighted rate of return (MWRR) incorporates the size and timing of cash flows, making it an effective measure for returns on a portfolio that has received deposits, dividend reinvestments, as well as interest payments, or has had withdrawals.

The MWRR is equivalent to the internal rate of return (IRR), where the net present value equals zero.


  • The average return is the simple mathematical average of a series of returns generated over a predetermined period of time.
  • The average return isn't equivalent to an annualized return, as it overlooks compounding.
  • The average return can assist with estimating the past performance of a security or portfolio.
  • The geometric average is dependably below the average return.
