Final answer:
The aftertax salvage value of the equipment is -$308,011.20.
Step-by-step explanation:
To calculate the after-tax salvage value of the equipment, we need to determine the depreciation tax shield for each year and then subtract it from the equipment's sale value.
- Calculate the annual depreciation amount by multiplying the equipment cost by the depreciation percentage for each year. The annual depreciation amounts for the 4-year project are $610,000, $976,000, $586,400, $351,840, and $351,840.
- Calculate the tax savings (depreciation tax shield) for each year by multiplying the annual depreciation amount by the tax rate of 34%. The tax savings for each year are $207,400, $331,840, $199,776, $119,497.60, and $119,497.60.
- Subtract the total tax savings from the equipment's sale value to get the after-tax salvage value. The equipment's sale value is $670,000, so the aftertax salvage value is $670,000 minus ($207,400 + $331,840 + $199,776 + $119,497.60 + $119,497.60) = $670,000 minus $978,011.20 = $-308,011.20.
