Methodology: Each property runs the same mechanics as the single-property Negative Gearing calculator (P&I/IO loan amortisation, Div 43 capital works at 2.5%, Div 40 diminishing value plant, post-9 May 2017 second-hand restriction). Tax is computed holistically -- portfolio-level net rental income feeds a single progressive schedule so bracket interactions are accurate. Capital gains apply the 50% discount when held >12 months and the marginal rate (incl. Medicare) in the sale year. Selling costs default to 2.5% agent commission plus $3,000 legal. Expenses default to benchmarks scaled by price.

Tax Accuracy & Sources

Reviewed: March 2026 · Tax year: 2025-26

This calculator is an estimate tool and may not cover all personal circumstances. For state-based taxes, confirm details with your state or territory revenue office.

How many properties can I model?
This calculator supports 1 to 4 investment properties, each with its own price, loan, rent, expenses, and depreciation schedule.
Does it account for CGT when selling?
Yes. You can set a sell year for each property (or hold to year 10). CGT is calculated with the 50% discount if held over 12 months, and selling costs are deducted from proceeds.
How are tax outcomes calculated?
Rental income, expenses, depreciation, and negative gearing are calculated for each property, then combined to determine your overall taxable income position. CGT events in sale years are included.
