Input guides
Capital growth — what it is and how to choose
Capital growth is the average annual change in the property’s value. It is cyclical and differs by suburb, dwelling type and timing. For planning, test a conservative case and a stronger case to see how sensitive your equity outcome is.
Income & tax — how this calculator handles it
Enter your current taxable income before this investment. We apply Australian resident tax rates from 1 July 2024 and estimate the tax effect of the rental result on a simplified year-by-year basis. This is useful for strategy, but it is not personal tax advice and does not include depreciation schedules or all property-specific deductions.
Settlement costs — duty, title/transfer and other cash costs
We estimate transfer duty using standard state schedules where workable. SA, TAS and ACT require a manual override because real scenarios vary too much. Title/transfer is editable, and the extra settlement % is for smaller legal, inspection and adjustment items not already broken out.
Price & funding — deposit and LMI
Set the purchase price and your deposit or available cash contribution. The calculator estimates indicative LMI from base LVR with investment, IO and larger-loan loadings. Choose whether to capitalise it or pay it as cash at settlement in the model.
Loan settings — IO to P&I and extra principal
Choose the total term, any interest-only period and any extra monthly repayment. Extra repayments reduce principal faster during P&I, but they are not the same thing as an offset account for flexibility and redraw behaviour.
Rent & expenses — the rental-income model
Enter weekly market rent, vacancy, management/variable expense %, and fixed annual costs. The model keeps these inputs simple so you can compare scenarios quickly.
Interest-only — pros and trade-offs
Interest-only reduces required repayments early and can improve short-term cash flow. The trade-off is that the loan balance stays higher for longer, so you rely more on growth and later principal reduction to build equity.
How we compare outcomes
Your net position equals equity at horizon plus cumulative after-tax rental cashflow, less non-recoverable cash settlement costs. Modelled financed items are not double-counted because they already sit inside the loan balance.
