The Fairmont Hotel in San Francisco needs to replace its air conditioning system. There are two alternatives, both of which can do the job equally well:

Machine name AC 1 AC 2
Purchase price $40,000 $60,000
Operating cost (end of each year) $17,000 $8,000
Useful life (years) 4 6
Straight line depreciation to zero over (years) 4 6
Salvage value at end of useful life $0 $0

The relevant discount rate is 10% and the marginal tax rate is 35%.

What is the equivalent annual cost for AC 1 (in absolute terms)?
What is the operating cash flow for AC 2 per year?
What is the equivalent annual cost for AC 2 (in absolute terms)?

Homework Answers

Answer #1
Machine name AC1 AC2
Purchase price 40000 60000
Operating cost per year (A) 17000 8000
Depreciation per year 10000 (40000/4) 10000(60000/6)
Tax savings on Depreciation (B) 3500 (10000x35%) 3500(10000x35%)
Cash outflow (A) -( B) 13500 4500
Present value annuity factor @10% , for 4 yar and 6 year 3.169 4.354
Present value of Cash flow 42781.5 (13500x3.169) 19593
Total Present value of cash outflow 82781.5 (40000+42781.5) 79593 (60000+19593)
Equalent Annual cost 26122.27 (82781.5/3.169) 18280.43

Now the answers

EAC of AC1 = 26122.27

Operating Cash flow of AC2 per year = 4500

EAC of AC2 = 18280.43
