Asset Depreciation Calculator

Estimate annual depreciation, book value, and total depreciation for an asset using straight-line or declining balance methods.

Your Details

Overview

This asset depreciation calculator helps you estimate how much value an asset may lose over time based on its purchase price, salvage value, useful life, and depreciation method. You can compare straight-line and declining balance results to support budgeting and basic asset tracking.

How it works

The calculator first works out the depreciable amount by subtracting the salvage value from the purchase price. Under the straight-line method, that amount is spread evenly across the useful life. Under the declining balance method, the asset loses a percentage of its remaining value each year, while keeping the final value at or above the salvage value. This gives you an estimated book value and total depreciation after the number of years entered.

How to use this calculator

  1. 1Enter the asset's purchase price.
  2. 2Add the expected salvage value at the end of its life.
  3. 3Enter the useful life in years.
  4. 4Choose how many years of use to calculate.
  5. 5Select the depreciation method.
  6. 6If using declining balance, enter the annual depreciation rate.

For an asset costing 10000 with a salvage value of 1000 and a 5-year life, straight-line depreciation is 1800 per year. After 3 years, total depreciation is about 5400 and book value is about 4600.

Frequently asked questions

What does this asset depreciation calculator estimate?

It estimates annual depreciation, total depreciation, and remaining book value based on the asset cost, salvage value, useful life, and method selected.

What is straight-line depreciation?

Straight-line depreciation spreads the depreciable amount evenly over the asset's useful life, so the same amount is depreciated each year.

What is declining balance depreciation?

Declining balance depreciation applies a fixed percentage to the asset's remaining value each year, so depreciation is usually higher in earlier years.

Why is salvage value important?

Salvage value is the estimated value left at the end of the asset's useful life. It reduces the amount that can be depreciated.

Can I use this calculator for tax depreciation?

You can use it for rough estimates, but tax depreciation rules often differ from accounting depreciation rules and may depend on local regulations.

Assumptions and warnings

Assumptions

  • Results are estimates for general planning and record-keeping.
  • The asset is depreciated once per year over its useful life.
  • Straight-line depreciation assumes the same amount is depreciated each year.
  • Declining balance depreciation uses the rate you enter and does not reduce the asset below its salvage value.

Warnings

  • This calculator provides an estimate only and is not accounting or tax advice.
  • Depreciation rules and accepted methods can vary by jurisdiction, asset type, and reporting purpose.
