About Straight-Line Depreciation

Straight-line depreciation is a method that allocates the depreciable cost of an asset evenly over its useful life.

The depreciable amount is the difference between the original cost of the asset and its estimated salvage value.

Example:

Asset Cost = $50,000
Salvage Value = $5,000
Useful Life = 10 years

Annual Depreciation = ($50,000 − $5,000) ÷ 10

Annual Depreciation = $4,500

This calculator is intended for educational and general accounting calculations. Actual financial reporting and tax depreciation may require additional rules or conventions.
