For example, a vehicle's value can be depreciated by how many miles it travels, or a machine based on how many operations it performs. The calculator allows you to enter different criteria based on your requirement.

After entering the initial and final values, select the criteria from the drop-down list, this gives relevant choices for the units in the "per" drop-down box. Note - you do not have to enter values, if they are omitted then the usage will still be calculated.

When you want to know the actual value that your asset, like a car or any other vehicle, has given to you over time, you have to first calculate the depreciation of them.

In other words, if an asset is losing its value constantly during its useful life then the method used for measuring this expense is annuity depreciation method.

The annuity depreciation calculator lets you do this calculation quickly. It gives you a chart showing expense of depreciation as usage and value. Using it is quite simple, you are only required to add the following details to know the usage depreciation and value depreciation of the asset.

  • Asset value - The original value of the asset for which you are calculating depreciation.
  • Final value - The expected final market value after the useful life of the asset.
  • Usage -The total expected usage during the entire useful life of the asset.
  • Increment - Expected annual usage of the asset.
  • (Note: The correct measure for usage and increment can be selected from the dropdown list while using iCalculator's annuity depreciation calculator)

    Steps to be followed to calculate Annuity Depreciation

    This method is used to compute constant rate of return on an asset. Below are the steps that should be followed for the calculation.

  • Future cash flow - This refers to any cash flow that could be associated with the asset in question in any given time during the useful life of the asset. It needs to be estimated to get the exact results.
  • Internal rate of return (IRR) - The next step will be to calculate the IRR on those estimated future cash flows.
  • IRR x Initial value - The next step is to multiply the calculated IRR with the initial value of the asset.
  • Next step is to subtract the result from the cash flow from the current period.
  • The Value residual is the depreciation expense or compound rate of interest on the asset.

    Depreciation calculation becomes a bit complicated for the assets where frequent additions, dismantling occur. It is not suitable for assets like machinery or industrial equipment.

    It can be troublesome to profit and loss accounting over time because of diminishing rate of depreciation each year.
