Australian Tax Depreciation Rate Helper is a tool that will help you work out the decline in value of assets.
Search for an asset in either Table A or Table B of the ATO classes, or browse through the categories.
Once you have found the asset, you can use the calculator to guide you to either the diminishing value or prime cost of the asset.
The app can produce a report similar to the ATO Decline in Value calculator in a useable PDF format.
Each asset has a calculated diminishing value, prime cost and effective life for reference.
