Equipment Depreciation Calculator
Estimate how much an asset depreciates over time using straight-line or declining balance depreciation.
Overview
This equipment depreciation calculator helps you estimate how an asset's value falls over time based on its purchase price, salvage value, useful life, years used, and depreciation method. It is useful for budgeting, record-keeping, and comparing depreciation approaches.
How it works
The calculator first finds the depreciable base by subtracting salvage value from purchase price. Under straight-line depreciation, that amount is divided evenly across the useful life. Under declining balance depreciation, the asset loses a fixed percentage of its remaining value each year. The current book value is reduced over the years used so far, but it does not go below the salvage value in this estimate.
How to use this calculator
- 1Enter the original purchase price of the equipment.
- 2Add the estimated salvage value at the end of its useful life.
- 3Enter the useful life in years and how many years the asset has already been used.
- 4Choose straight-line or declining balance depreciation.
- 5If you choose declining balance, enter the annual depreciation rate.
- 6Review the estimated annual depreciation, current book value, and total depreciation.

For equipment costing $25,000 with a $5,000 salvage value and a 5-year useful life, straight-line depreciation is $4,000 per year. After 2 years, the estimated book value is $17,000 and total depreciation is $8,000.
Frequently asked questions
What does this equipment depreciation calculator estimate?
It estimates annual depreciation, total depreciation to date, and the current book value of equipment based on the inputs you provide.
What is straight-line depreciation?
Straight-line depreciation reduces the asset's value by the same amount each year over its useful life.
What is declining balance depreciation?
Declining balance depreciation applies a fixed percentage to the remaining book value each year, so earlier years usually have higher depreciation.
Why is salvage value included?
Salvage value is the estimated amount the equipment may be worth at the end of its useful life, and it limits the depreciable amount.
Can this calculator be used for tax depreciation?
It can help with general estimates, but tax depreciation rules often differ from accounting depreciation and vary by location.
What happens if years used is greater than useful life?
The estimate may no longer reflect a typical depreciation schedule, and the book value is limited so it does not fall below the salvage value in this calculator.
