You are evaluating two mutually exclusive machines used in your firm's production process. The ABC machine costs $261,000, has a 3-year life, and has pretax operating costs of $60,500 per year. XYZ machine costs $455,000, has a 5-year life, and has pretax operating costs of $32,000 per year. For both machines, use straight-line depreciation to zero over the machine's life and assume a salvage value of $47,000. If your firm's tax rate is 35% and your discount rate is 9%, compute the equivalent annual cost for both machines.
EAC for ABC machine = $
EAC for XYZ machine = $
(Round EAC's to the nearest $ value. Do not enter a '$' symbol. EACs are negative, so use a minus sign to indicate a negative number, as in '-2345.').
Cost of Machine ABC | 261,000 | |
Life of Machine ABC | 3 | years |
Operating Cost (pre-tax) | 60,500 | |
Salvage Value ABC | 47,000 |
Tax Rate | 35% |
Discount Rate | 9% |
The depreciation per year for machine ABC is calculated on a
straight line basis as follows
Depreciation ABC (per year) = (Cost of Machine ABC - Salvage Value
ABC) / (Life of Machine ABC)
= (261,000-47,000) / 3 = 71,333
To calculate the equivalent annual cost, let us first calculate
the cashflow for Machine ABC
A negative value signifies cash outgo, and a positive signifies a
cash inflow
Year 0 | Cost of Machine ABC | (261,000) | |
Year 1 | Operating Cost X (1-Tax Rate) | (39,325) | |
Depreciation Benfit | 24,967 | ||
Year 2 | Operating Cost X (1-Tax Rate) | (39,325) | |
Depreciation Benfit | 24,967 | ||
Year 3 | Operating Cost X (1-Tax Rate) | (39,325) | |
Depreciation Benfit | 24,967 | ||
Salvage Cost | 47,000 |
Depreciation Benefit arises because if one purchases the
machine, they can charge the depreciation to the profit & loss
account and claim tax benefit. Thus,
Depreciation Benefit = Tax Rate X Depreciation charge per
year
=35% X 71,333 = 24,967
Also, operating costs can be set-off against the revenues of the company and thus, we need to consider the post-tax operating costs = Operating Costs X (1 - Tax Rate)
Thus, the cashflow in the case where the machine ABC is purchased is
Year 0 | (261,000) |
Year 1 | (14,358) |
Year 2 | (14,358) |
Year 3 | 32,642 |
Thus the Net Present Value (NPV) = 239,498
To calculate the Equivalent Annaulized cost for Machine
ABC, we need to use the PMT Function in excel
EUAC Machine ABC = PMT (rate, no. of years, NPV of
Machine ABC cashflow, 0, 0)
EUAC Machine ABC = PMT( 9%, 3, 239498),0,0)
= -94,615
The calculations for Machine XYZ are similar
Cost of Machine ABC | 261,000 | |
Life of Machine ABC | 3 | years |
Operating Cost (pre-tax) | 60,500 | |
Salvage Value ABC | 47,000 |
Tax Rate | 35% |
Discount Rate | 9% |
The depreciation per year for machine XYZ is calculated on a
straight line basis as follows
Depreciation XYZ (per year) = (Cost of Machine XYZ - Salvage Value
XYZ) / (Life of Machine XYZ)
= (455,000-47,000) / 5 = 81,600
To calculate the equivalent annual cost, let us first calculate
the cashflow for Machine ABC
A negative value signifies cash outgo, and a positive signifies a
cash inflow
Year 0 | Cost of Machine XYZ | (455,000) | |
Year 1 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Year 2 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Year 2 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Year 3 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Year 4 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Year 5 | Operating Cost X (1-Tax Rate) | (20,800) | |
Depreciation Benfit | 28,560 | ||
Salvage Cost | 47,000 |
Depreciation Benefit arises because if one purchases the
machine, they can charge the depreciation to the profit & loss
account and claim tax benefit. Thus,
Depreciation Benefit = Tax Rate X Depreciation charge per
year
=35% X 81,600 = 28,560
Also, operating costs can be set-off against the revenues of the company and thus, we need to consider the post-tax operating costs = Operating Costs X (1 - Tax Rate)
Thus, the cashflow in the case where the machine XYZ is purchased is
Year 0 | (455,000) |
Year 1 | 7,760 |
Year 2 | 7,760 |
Year 3 | 7,760 |
Year 4 | 7,760 |
Year 5 | 54,760 |
Thus the Net Present Value (NPV) = 239,498
To calculate the Equivalent Annaulized cost for Machine
ABC, we need to use the PMT Function in excel
EUAC Machine XYZ = PMT (rate, no. of years, NPV of
Machine ABC cashflow, 0, 0)
EUAC Machine XYZ = PMT( 9%, 5, 361715,0,0)
= -92,994
To summarize
EUAC Machine ABC = -94,615
EUAC Machine XYZ = -92,994
