Worked accounting example
Equipment costs $10,000, has $1,000 residual value and a five-year life. Straight-line depreciation is ($10,000 − $1,000) ÷ 5 = $1,800 each year. Book value after year two is $6,400.
Accounting formulas and common mistakes
Depreciation expense reduces the carrying amount of an asset. Straight-line spreads depreciable cost evenly. Double-declining balance uses an accelerated rate and never depreciates below residual value in this exercise.
