Depreciation Formula Explained
The general depreciation formula is:
Depreciation Expense = (Cost of Asset – Salvage Value) ÷ Useful Life
For example, if you buy equipment worth $10,000 with a salvage value of $1,000 and a useful life of 5 years, your depreciation expense per year using the straight line depreciation calculator would be:
(10,000 – 1,000) ÷ 5 = $1,800 per year
This method is widely used because it’s simple and easy to apply.
How to Calculate Depreciation Step by Step
- Determine the cost of the asset (purchase price).
- Estimate the useful life of the asset in years.
- Decide the salvage value (resale or scrap value at the end of useful life).
- Apply the right depreciation expense formula depending on the method.
- Track the accumulated depreciation (total depreciation expense over time).
For businesses, this connects directly to the assets equation in accounting:
Assets = Liabilities + Equity.
Depreciation reduces the book value of assets over time, impacting the balance sheet.
