Diving Deep into Depreciation Methods
1. Straight-Line Depreciation
Formula: (Cost - Salvage Value) / Useful Life
Best for: Assets that depreciate steadily over time (e.g., buildings).
Pros:
- Simple to calculate and understand
- Consistent expense each year
Cons:
- May not reflect actual value decline accurately for all assets
Example: A $10,000 asset with a 5-year life and $1,000 salvage value depreciates $1,800 annually.
2. Double Declining Balance
Formula: 2 Ă— Straight-line rate Ă— Book value at beginning of year
Best for: Assets that lose value quickly in early years (e.g., computers, vehicles).
Pros:
- Larger tax deductions in early years
- Often more accurate for tech assets
Cons:
- More complex calculations
- Smaller deductions in later years
Example: For the same $10,000 asset, first-year depreciation would be $4,000 (2 Ă— 20% Ă— $10,000).
3. Sum-of-Years' Digits (SYD)
Formula: (Remaining life / Sum of years) Ă— (Cost - Salvage Value)
Best for: Assets with moderate acceleration in early years.
Pros:
- Accelerated, but less extreme than double declining
- Balances early depreciation with gradual taper
Cons:
- More complex calculations
- May overstate depreciation for some assets
Example: For a 5-year asset, SYD = 5+4+3+2+1 = 15. First year: (5/15) Ă— $9,000 = $3,000
4. Units of Production
Formula: (Number of units produced / Life in units) Ă— (Cost - Salvage Value)
Best for: Assets where usage varies significantly year to year (e.g., manufacturing equipment).
Pros:
- Matches depreciation to actual asset use
- Useful for industries with fluctuating production
Cons:
- Requires accurate production forecasts
- More complex record-keeping
Example: A machine can produce 100,000 units in its lifetime. If it produces 20,000 units in year 1, depreciation is (20,000/100,000) Ă— $9,000 = $1,800.
