To arrive at this figure, the stock calculator divides the total return on investment by the total original investment, and then multiplies that result by 1/N, where N is the number of years the investment is held = 3% + 5% + 6% = 14%. Thus, the expected return of the portfolio is 14%. Note that although the simple average of the expected return of the portfolio's components is 15% (the average of 10%, 15%, and 20%), the portfolio's expected return of 14% is slightly below that simple average figure The expected return of the portfolio is calculated by aggregating the product of weight and the expected return for each asset or asset class: Expected return of the investment portfolio = 10% * 7% + 60% * 4% + 30% * 1% = 3.4% You can also copy this example into Excel and do an individual calculation for your investments Bankrate.com provides a FREE return on investment calculator and other ROI calculators to compare the impact of taxes on your investments
