About Depreciation Calculator

This calculator helps you determine the annual depreciation deduction for your real estate property. The IRS allows you to depreciate:

  • Residential properties over 27.5 years
  • Commercial properties over 39 years

The calculator provides:

  • Building value (property value minus land value)
  • Annual depreciation amount
  • Total depreciable amount
  • Remaining value after first year's depreciation

Note: Land value is not depreciable, which is why it must be subtracted from the total property value.
