Equipment costing $344,000 has a salvage value of $20,000 after 5 years. Find the annual depreciation and the book value at the end of year 2.
Given
C = $344,000
S = $20,000
Find
D and BV
Start with the thinking
- Straight line spreads the depreciable base evenly.
- The depreciable base excludes salvage.
Step-by-step solution
Annual depreciation
Substituting — D = ($344,000 − $20,000)/5 = $64,800 per year
Book value
Substituting — BV = $344,000 − 2($64,800) = $214,400
D = $64,800/yr; BV(2) = $214,400
Why the other options are there
- D = $68,800 (salvage not deducted)
- BV = $20,000 (final-year value reported)

Equipment costing $116,000 has a salvage value of $33,000 after 14 years. Find the annual depreciation and the book value at the end of year 3.
Given
C = $116,000
S = $33,000
Find
D and BV
Start with the thinking
- Straight line spreads the depreciable base evenly.
- The depreciable base excludes salvage.
Step-by-step solution

Book value
Substituting — BV = $116,000 − 3($5,929) = $98,214
D = $5,929/yr; BV(3) = $98,214
Why the other options are there
- D = $8,286 (salvage not deducted)
- BV = $33,000 (final-year value reported)
