Getting Started


The tool has two tabs, one for the straight-line, and one for reducing balance method. For straight-line depreciation you’ll first need to fill in the “Fixed Asset Information” box in the top left (just under the Zervant logo). This includes:

  • The value of the asset when it was purchased.
  • Its’ expected lifetime (in your business).
  • And an estimated residual value.

Warning! Be sure not to enter anything in the grey box. This contains a formula that will calculate the asset’s annual depreciation, based on the information you provide.

The tool will then automatically fill out the “Straight-line Depreciation Table” for you. It will provide information for the number of years you have stated as the “expected lifetime” of the asset eg. if you’ve written 5 years the tool will provide 5 rows of data. It can calculate up to a maximum of 20 years.

If you need a figure for reducing balance depreciation, switch to the appropriate tab at the bottom. Then follow exactly the same procedure as above – fill in all the fields in the “Fixed Asset Information” box in the top left. (There is no grey box in this formula, as annual depreciation is not a constant figure when using the reducing balance method.) The tool will calculate everything else for you.
