When considering the current value of the investment, be sure to include any dividends or other profits you’ve taken from the asset. When calculating the initial value, be sure to include things like trading commissions.
Simple Exercise: Take your house for example and calculate it’s value now, what you originally paid for it and what it cost. What you originally paid for it and what it cost should be the same.
Consider that the initial cost could be considered lower now than it was when you bought your home due to the payments. How does that affect your ROI?
