Question

$400,000 capital cost required for purchasing a machine (at time zero) that can generate revenue of $180,000 with operating cost of $35,000 for five years (from year 1 to year 5). The capital cost is depreciable over 6 years (from year 0 to year 5) based on MACRS 5-year life depreciation with the half year convention (table A-1 at IRS). The salvage value will be zero and working capital $50,000. Please calculate NPV and ROR for this project considering the minimum rate of return 10% and 35% income tax.

Explanation / Answer

Depreciation as per Macrs Method

Depreciation for the first year = Cost x 1/ Useful life x A x Convention

= 400000 x 1/5 x 200% x 0.50

= $80000

Depreciation for the second year = [Cost - Depreciation charged in the previous years] x 1/ Recovery Period x A x Convention

= [400000 - 80000] x 1/4 x 200% x 1

= $160000

Depreciation for the third year = [Cost - Depreciation charged in the previous years] x 1/ Recovery Period x A x Convention

= [400000 - 240000] x 1/3 x 200% x 1

= $106667

Depreciation for the fourth year = [Cost - Depreciation charged in the previous years] x 1/ Recovery Period x A x Convention

= [400000 - 346667] x 1/ 2 x 200% x 1

= $53333

Depreciation for the fifth year = [Cost - Depreciation charged in the previous years] x 1/ Recovery Period x A x Convention

= [400000 - 400000] x 1/1 x 200% x 1

= $0

Tax Saving on Depreciation:

Year 1 = 80000 x 0.35 = $28000

Year 2 = 160000 x 0.35 = $56000

Year 3 = 106667 x 0.35 = $37333

Year 4 = 53333 x 0.35 = $18667

Cash flow after tax per year:

Present Value of Cash outflow = 400000 + 50000 = $450000

NPV = 411173 - 450000 = -$38827
