Answer: $12,943.10
Step-by-step explanation:
To answer let us begin with knowing the MACRS percentages.
Both machines are considered a 3 year class for MACRS.
3 Year MACRS percentages are as follows,
Year 1= 33.33%
Year 2=44.45%
Year 3=14.81%
Year 4=7.41%
To calculate the Incremental cash flow we would need to subtract the tax on the Pre-tax savings as well as the depreciation tax shield.
DEPRECIATION TAX SHIELD.
Depreciation on New Machine is,
= First year MACRS * purchase price.
= 33.33% * 87,000 ( include installation price)
= $28,997.10
Subtract depreciation on original machine which is now in FOURTH year so we use the 4 year depreciation rate,
= 61,000 * 7.41%
= $4,520.10
Subtracting them would give,
= 28,997.10 - 4,520.10
= $24,477
This is the Additional depreciation.
We need to calculate the tax shield on it.
= 24,477 * 30%
= $7,341.10 is the tax shield.
Now to calculate the Incremental Cash flow.
= Pre-tax Savings - (tax on Pre-tax Savings) + Depreciation tax shield
= 8,000 - (8,000 * 30%) + 7,341.10
= $12,943.10
$12,943.10 is the Incremental Cash flow in year 1.
