Negative gearing is one of Australia's most talked-about tax strategies. It occurs when your investment property expenses (loan interest, maintenance, depreciation) exceed rental income — creating a 'loss' that reduces your taxable income and therefore your tax bill. While it doesn't make money on its own, the tax benefit combined with potential capital growth and rental income growth can create long-term wealth. This calculator shows you the real numbers.

§ Worked examples

Real-world scenarios

Standard Negative Gearing

Jenny buys a $650,000 unit, borrows $520,000 at 6.2%, rents for $550/week. Expenses: $9,000/year. Depreciation: $10,000/year. Marginal rate: 37%.

Annual rent: $28,600. Interest: $32,240. Expenses: $9,000. Depreciation: $10,000. Total costs: $51,240. Net loss: $22,640. Tax saving at 37%: $8,377/year ($161/week). After-tax cost of holding: $14,263/year ($274/week).

Positively Geared Property

Same property but in a regional area: $400,000 purchase, $320,000 loan at 6.2%, $450/week rent.

Annual rent: $23,400. Interest: $19,840. Expenses: $6,000. Depreciation: $6,000. Total costs: $31,840. Net loss: $8,440. At 37% rate: $3,123 tax saving. If rates drop or rent rises, this property could flip to positive gearing.
