To calculate the annual depreciation expense using the straight-line method, you can follow these steps:
- Determine the cost of the equipment: $17,000
- Determine the salvage value: $2,000
- Determine the useful life: 5 years
The formula for annual depreciation using the straight-line method is:
\[ \text{Annual Depreciation} = \frac{\text{Cost} - \text{Salvage Value}}{\text{Useful Life}} \]
Plugging in the values:
\[ \text{Annual Depreciation} = \frac{17,000 - 2,000}{5} = \frac{15,000}{5} = 3,000 \]
So, the annual depreciation expense is $3,000.
Next, let's find the book value of the equipment at the end of each year.
-
End of Year 0: \[ \text{Book Value} = 17,000 \]
-
End of Year 1: \[ \text{Book Value} = 17,000 - 3,000 = 14,000 \]
-
End of Year 2: \[ \text{Book Value} = 14,000 - 3,000 = 11,000 \]
-
End of Year 3: \[ \text{Book Value} = 11,000 - 3,000 = 8,000 \]
-
End of Year 4: \[ \text{Book Value} = 8,000 - 3,000 = 5,000 \]
-
End of Year 5: \[ \text{Book Value} = 5,000 - 3,000 = 2,000 \]
In conclusion, the book values at the end of each year are:
- End of Year 0: $17,000
- End of Year 1: $14,000
- End of Year 2: $11,000
- End of Year 3: $8,000
- End of Year 4: $5,000
- End of Year 5: $2,000
This matches the information depicted on your graph, showing a linear depreciation down to the salvage value over the 5-year period.
