Return on Investment

Return on Investment
Return on investment refers to a sort of performance measure normally used to investigate or evaluate how efficient an investment is, compared to other potential investments. In order to successfully evaluate the return of an investment, also referred to as ROI; the benefit or return, normally calculated as the difference between the gain from investment and the cost of investment, is divided by the cost of investment. The gain from investment essentially refers to the proceeds that may be obtained from selling the investment. Alternatively, it can also be calculated simply as the amount of value gained, divided by the cost of the investment. ROI is a very popular metric in part due to its simplicity, as well as its versatility and the fact that it allows for the incorporation of factors such as inflation and recognizes the concept of the time value of money. At face value, ROI allows for an individual to objectively select amongst a collection of investment opportunities, simply on the value of the investment’s ROI, the higher the ROI, the better the investment.

Return on Investment
Investment =Stamp duty + Initial median house price for the year
Initial Median House Price= 450000
Stamp duty = 17,165
Simple ROI = (850*3)+(685*3)+(660*3)+(700*3)+(500,000-450000)/467,165= 2550+2055+1980+2100+50,000/467165 = 0.12356*100=
= 12.56%
ROI = 1800+2250+1740+1650-15000/523432 = -0.0144*100 = -1.44%
= -1.44%
ROI = 2580 + 2400 + 2019 + 1260 – 15000/502462 = -0.0134*100 = -1.34%
= -1.34%
ROI = 3300+4620+26000/490,940 = 0.0691*100

First Quarter
Assuming the price of the house at the beginning of the year is the same as at the end of 2012 ($500,000). Capital gain =$295,000

Initial Share Price 5.38
Closing Share Price 4.40
Total Dividends = 0.30
ROI = 0.30 + -0.98/5.38 = -0.126*100
