Suppose a resident with yearly income of $40,000.00. The Medicare Levy will be $600.00 and the taxes will be $5,550.00/year or $106.73/week. His/her net salary per year will be $33,850.00 or $650.96 per week. Suppose the user needs $628.71 per week as living expenditure. So it is possible to invest $22.25 per week. Suppose the interest is 13% per year (or 1% each 4 weeks, since we have 52 weeks per year) and the number of weeks the user will invest the money is 18. Assuming the user asks to invest $22.25 per week, then the investment account output will be:
Weeks
Money in the end of each 4 weeks
4
$89.89 = 22.25*4*1.01
8
$180.68 = (89.89+22.25*4)*1.01
12
$272.38 = (180.68+22.25*4)*1.01
16
$364.99 = (272.38+22.25*4)*1.01
18
$409.49 = (364.99 + 22.25*2) (note that is less than 4 weeks, so the interest is not applied
