Investor Strata ROI Calculator

Enter your property details — purchase price, expected rent, and all ongoing expenses including strata fees. The calculator computes your gross and net rental yield, annual cash flow, and break-even rent. It then projects your total return over the holding period, combining rental income with estimated capital growth.

Strata fees are often the largest ongoing expense after mortgage interest for apartment investors. This calculator isolates the impact of strata fees on your returns and includes a sensitivity analysis showing how your yields change if fees were 20% higher or lower — helping you stress-test your investment before committing.

The holding period projection uses compound capital growth and assumes constant annual rental income and expenses for simplicity. In practice, rents and expenses both tend to increase over time — the projection gives you a baseline to work from.

• You're evaluating a strata property as an investment and want to understand the true net yield after all expenses
• You want to see how strata fees compare to your gross rental income as a percentage
• You're comparing two properties with different strata fees and need to see the long-term impact on total returns
• You want to know the minimum rent needed to break even on holding costs
• You're stress-testing your investment against potential strata fee increases

Gross vs Net Rental Yield

Gross yield is annual rent divided by purchase price — it ignores expenses. Net yield subtracts all holding costs (strata fees, council rates, water, management fees, insurance) from rent before dividing by purchase price. Net yield is the more meaningful figure for investment decisions, and strata fees often account for the largest gap between the two.

Strata Fees as % of Gross Rent

This metric shows what proportion of your rental income goes to strata fees alone. A typical range is 10–25% for apartments. Above 25%, strata fees are significantly eating into your returns. Buildings with pools, gyms, concierge, or lifts tend to sit at the higher end.

Break-Even Rent

The minimum weekly rent needed to cover all annual expenses (strata, council, water, management, insurance) — excluding mortgage costs. Below this figure, the property generates negative cash flow even before debt servicing. This is a key metric for assessing downside risk if rental demand softens.

Total Return (Cash Flow + Capital Growth)

Total return combines your cumulative net cash flow (rent minus expenses over time) with estimated capital gains. Many negatively geared properties still deliver strong total returns when capital growth is factored in — but you need sufficient income to fund the annual shortfall.
