An engineer uses a economic analysis to determine which of two different machines to purchase. The machine is capable of performing the task. Assume the minimum attractive rate of return of 4% compounded semiannually. What is the annual worth of the machine?
Initial cost = $11,000
Estimated life = 10 years
Salvage value = $3,500
Semiannual maintenance cost = $475
Semiannual income = 2,475
Semi-Annual inflows | 2475 | |||
Less: Operating cost | 475 | |||
Net inflows | 2000 | |||
Annuity factor (i=2% n=20) | 16.351 | |||
Present value of Inflows | 32702 | |||
Aadd: Present value off salvage | 2355.5 | |||
($ 3500*0.673) | ||||
Total Present value of inflows | 35057.5 | |||
Less: Initial Investment | 11000 | |||
Present worth | 24057.5 | |||
Divide: Annuity factor | 16.351 | |||
Annualised Equivalent cash flows | 1471.317 | |||
Present worth of project: | 24058 | |||
Annualised Equivalent flows: | 1471 | |||
