A family is planning to buy a vacation cabin for $30,000. The family intends to keep the cabin for 6 years and expects the annual unkeep and taxes to amount to $900 per year. Without any major repairs, the cabin should have a resale price of $26,000. What is the equivalent annual cost of owning the cabin if the family’s acceptable interest rate is 6%?
The Equivalent Annual Cost of Machine A is computed as shown below:
= (Initial investment + present value of future cost) / Present value annuity factor of 6% for 6 years
Initial investment + present value of future cost is computed as follows:
= $ 30,000 + $ 900 / 1.061 + $ 900 / 1.062 + $ 900 / 1.063 + $ 900 / 1.064 + $ 900 / 1.065 + $ 900 / 1.066 - $ 26,000 / 1.066
= $ 16,096.61784
Present value annuity factor of 6% for 6 years is computed as follows:
= [ (1 – 1 / (1 + r)n) / r ]
= [ (1 - 1 / (1 + 0.06)6 ) / 0.06 ]
= 4.917324326
So, the equivalent annual cost is computed as follows:
= $ 16,096.61784 / 4.917324326
= $ 3,273.45 Approximately
