What Is a Depreciation Calculator?

The depreciation calculator computes annual asset depreciation using both the straight-line and double declining balance methods and shows the book value year by year, helping with cost allocation and asset planning.

How to Use

Using the depreciation calculator is simple:

  • Enter the asset cost and estimated salvage value
  • Enter the useful life in whole years
  • View the annual depreciation for both methods and the depreciation table

Tips

  • Salvage value must be less than the asset cost
  • The double declining balance method automatically converges to salvage value at the end
  • This tool is for estimation - consult a professional for tax questions

Frequently Asked Questions

What is the difference between straight-line and double declining balance?+
Straight-line depreciation is the same every year and simple to calculate. Double declining balance is an accelerated method: higher depreciation in early years and less later, matching how equipment loses value quickly.
What is salvage value?+
Salvage value is the estimated remaining value of an asset at the end of its useful life. It must be lower than the asset cost. Total depreciation = Cost − Salvage value.
Which method is better for taxes?+
Tax rules vary by region. Straight-line is widely accepted and simple. Accelerated methods (like double declining balance) are used for certain asset classes in some countries - consult a tax professional.
What does the results table include?+
The table shows the annual depreciation and ending book value for both methods year by year, making it easy to compare and prepare depreciation details.
