Property Investment Calculators

Making the Numbers Work on Australian Investment Property

Property investment in Australia is a serious financial commitment — and the difference between a portfolio that builds real wealth and one that quietly drains your cash flow often comes down to whether you ran the numbers properly before you bought. These calculators cut through the complexity of rental yields, gearing, tax and borrowing costs so you can assess any deal with confidence.

Gross Yield vs Net Yield: Why the Gap Matters

Most property listings quote gross rental yield — annual rent divided by purchase price, expressed as a percentage. A property advertised at 5.5% gross sounds solid, but once you subtract property management fees (typically 7–10% of rent), council rates, water rates, insurance, maintenance, and vacancy allowances, the net yield can fall to 3.5% or lower. Always run our Rental Yield Calculator using your realistic net income, not the headline figure.

How Negative Gearing Works (and When It Makes Sense)

A property is negatively geared when the rental income is less than the interest and holding costs. The shortfall is a deductible loss that reduces your taxable income — so the ATO effectively subsidises part of your holding cost. At a 37% marginal rate, a $10,000 annual loss costs you only $6,300 out of pocket after the tax benefit. This only makes economic sense, however, if you expect strong capital growth to compensate. Our Negative Gearing Calculator shows your true after-tax holding cost so you can compare properties on equal footing.

Capital Gains Tax and the 50% Discount

When you sell an investment property held for more than 12 months, only 50% of your capital gain is included in your assessable income. This CGT discount is one of the most powerful concessions in the Australian tax system — a $200,000 gain becomes a $100,000 addition to your taxable income for the year of sale. Timing a sale to a low-income year (say, after retirement) can reduce the effective CGT rate dramatically. Factor this into your long-term return projections using our Capital Gains Tax Calculator.

Depreciation Schedules: Free Tax Deductions You Might Be Missing

New and near-new investment properties attract depreciation deductions for both the building structure (Division 43, at 2.5% per year over 40 years) and plant and equipment items (Division 40 — appliances, carpet, blinds). A quality depreciation schedule from a quantity surveyor costs $500–700 and can generate $3,000–8,000 in first-year deductions on a new property. You don't need a calculator for this one — just a good quantity surveyor and a claim in your next tax return.

Offset vs Redraw: Which Saves You More?

On your primary residence or a property you plan to move into, keeping savings in an offset account rather than redrawing is usually the smarter structure. Redrawing contaminated funds can compromise tax deductibility on investment loans — a well-documented ATO risk area. Our Offset Account Calculator shows exactly how much interest you save by parking cash in offset versus a separate savings account.

Whether you're analysing your first investment property or managing a multi-property portfolio, having the right tools means fewer surprises come tax time — and better decisions before settlement day.
