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:
