Worked example
Property: $700,000 unit in Brisbane. Loan: $560,000 at 6.2%.
| Rental income (52 weeks @ $600) | $31,200 |
| Interest on loan | −$34,720 |
| Property management (8%) | −$2,496 |
| Council rates + water | −$3,400 |
| Insurance | −$1,800 |
| Repairs + maintenance | −$1,500 |
| Body corporate | −$3,200 |
| Depreciation (Div 40 + 43) | −$8,000 |
| Rental loss | −$23,916 |
At a 39% marginal tax rate, this loss reduces tax by ~$9,327. The out-of-pocket cost drops from $23,916 to $14,589 per year — the difference is what negative gearing subsidises. Model your own property in the negative gearing calculator using the 2025-26 ATO brackets.
Whether it's worth it
Negative gearing is only good economics if capital growth outpaces the after-tax income loss. Rule of thumb: for a $700k property with a $15k after-tax loss/year, you need >2.1% annual capital growth just to break even, plus growth to actually make money.
What's not deductible
- Loan principal repayments (only interest is deductible)
- Improvements (added to cost base for CGT, or depreciated at 2.5% under Division 43)
- Second-hand plant and equipment on properties acquired after 9 May 2017 (Division 40 restriction)
- Expenses incurred while the property is not genuinely available for rent
