Prime Cost vs Diminishing Value - What It Means for Your Investment Property

Understanding depreciation is one of those areas that can make a real difference to your property investment strategy, particularly when it comes to cash flow.

For residential investors, depreciation generally falls into two key categories:

• Capital works deductions (Division 43)
• Plant and equipment depreciation (Division 40)

Capital works deductions relate to the building itself, including structural elements like walls and the roof. These can typically be claimed at 2.5 per cent per year over the life of the property.

Plant and equipment, on the other hand, covers removable or mechanical assets such as carpets, hot water systems, ovens, blinds and light fittings. This is where things become more strategic, as there are two different methods available to calculate depreciation.

Diminishing value: higher deductions earlier

The diminishing value method is designed to deliver higher depreciation deductions in the earlier years of ownership.

Under this approach, depreciation is calculated each year as a percentage of the asset’s remaining value, which reduces over time. As that value decreases, so does the annual claim, until the asset is eventually written down to zero.

In simple terms, this method tends to bring forward deductions, which many investors find appealing as it can improve cash flow earlier and potentially support faster debt reduction or reinvestment.

Prime cost: steady and predictable

The prime cost method takes a more consistent approach.

Depreciation is calculated based on a percentage of the asset’s original cost each year, which means deductions are spread more evenly across the asset’s effective life. This is why it is often referred to as a straight line method.

For investors who prefer predictability, or who expect their financial position to change over time, this steady pattern can be a better fit.

Which method is right for you?

There is no one-size-fits-all answer.

While diminishing value is often chosen for its stronger early-year returns, prime cost may suit those looking for a more balanced, long-term approach.

One important point to be aware of is that once a depreciation method is selected, it cannot be changed. This makes it essential to consider your broader investment goals, income position and long-term strategy before making a decision.

Getting the right advice

Specialist quantity surveyors, such as BMT Tax Depreciation, will typically calculate depreciation using both methods, allowing you to see the different outcomes. Your accountant can then help determine which approach aligns best with your circumstances.

If you would like to better understand what depreciation could look like for your property, including the impact of both methods, having a tax depreciation schedule prepared can provide a clear breakdown of available deductions.
