Things You Need to Know

You don't have to purcahse a depreciation schedule before you make any desision by using this free depreciation calculator to estiamte property depreciation for your potential rental property although you have to use the investment property depreciation from a formal depreciation schedule from a qualified quantity surveryor when doing your tax return.

There are two methods on how to calculate rental property depreciation: diminishing value method and prime cost method.

Here are the ATO definitions of the diminishing value method and prime cost method:

The diminishing value method assumes the decline in value each year is a constant proportion of the remaining value and produces a progressively smaller decline over time.

The diminishing value method decline in value deductible amount of a depreciating asset for an income year is the opening adjustable value divided by either:

(a) the effective life, multiplied by 1.5. This applies to the assets you started to hold before 10 May 2006, or

(b) the effective life, multiplied by 2.0. This applies to the assets you started to hold on or after the 10 May 2006,

reduced by your percentage of non-taxable use of the asset.

The prime cost method assumes that the value of a depreciating asset decreases uniformly over its effective life.

The prime cost method decline in value of a depreciating asset for an income year deductible amount is the lesser of:

(a) the cost divided by the effective life apportioned for any part year ownership, and

(b) the opening adjustable value,

reduced by the percentage of non-taxable use to ensure that the deduction relates only to the taxable use of the asset.
