The syntax for the DB function is:
DB(cost, salvage, life, period, [month])- cost: Initial cost of the asset
- salvage: Value at the end of depreciation (salvage value)
- life: Number of periods for depreciation (useful life)
- period: Specific period for depreciation calculation
- month: (Optional) Number of months in the first year (default is 12)
Practical Examples
The DB function can be applied to various scenarios:
- Office Equipment:
=DB(10000, 1000, 5, 1)for $10,000 equipment with 5-year life and $1,000 salvage value - Vehicle:
=DB(20000, 2000, 8, 1)for a $20,000 vehicle with 8-year life and $2,000 salvage value - Machinery:
=DB(50000, 5000, 10, 1)for $50,000 machinery with 10-year life and $5,000 salvage value
