A piece of construction equipment costs $120,000 with an estimated useful life of 8 years and a salvage value of $8,000. Using the straight-line depreciation method, what is the annual depreciation expense?
Correct Answer
D) $14,000
Straight-line depreciation = (Cost - Salvage Value) ÷ Useful Life. ($120,000 - $8,000) ÷ 8 years = $112,000 ÷ 8 = $14,000 per year.
Why This Is the Correct Answer
Option B ($14,000) is correct because it properly applies the straight-line depreciation formula. The formula subtracts the salvage value from the initial cost to find the total depreciable amount, then divides by the useful life. This method spreads the depreciation evenly over the equipment's useful life, which is the defining characteristic of straight-line depreciation. The calculation yields exactly $14,000 per year in depreciation expense.
Why the Other Options Are Wrong
Option B: $15,000
Option C ($15,000) is incorrect because it appears to ignore the salvage value entirely, calculating $120,000 ÷ 8 = $15,000, which violates the straight-line depreciation formula.
Option C: $16,000
Option A ($12,000) is incorrect because it appears to divide the total cost by 10 years instead of 8 years, or fails to properly account for the salvage value in the calculation.
Memory Technique
Remember 'CSV' - Cost minus Salvage, then divide by Years. Think 'Cost Saves Value' to remember you subtract salvage value from cost first.
Reference Hint
Look up 'Depreciation Methods' or 'Straight-Line Depreciation' in the accounting or business management section of your contractor reference manual.
