How much can I borrow for my home loan?

Your questions answered

Most lenders will accept a deposit between 5% and 20%.

If you have a 20% deposit, you can usually avoid Lenders Mortgage Insurance (LMI). If your deposit is smaller, you may still be able to get a loan, but you may need to pay LMI.

Some lenders also offer options to help you buy sooner, such as using a guarantor if you don’t have a full deposit.

Terms, conditions, fees, charges and credit criteria apply.

Your borrowing power is based on your overall financial situation.

Lenders look at things like your income, living expenses, existing debts, and your credit history to work out how much you may be able to borrow.

Many borrowers look at their borrowing power and assume that’s how much they should borrow.

A better approach is to consider what you can comfortably afford to repay, taking into account your expenses, financial commitments and the possibility that your circumstances may change in the future.

Calculator Disclaimer

This calculator should be used as an indication only. Results provided are estimates for illustrative purposes and based on the information provided and the assumption that calculations are for new borrowings only. These assumptions are subject to change. Results should not be relied on or construed as financial or other advice. Results do not represent a quote or pre-qualification for a loan or other product.

This calculator applies the Household Expenditure Measure (HEM) to pre-populate minimum living expenses, to ensure that you allow adequate funds to live on. We include an interest rate buffer in our calculations. This allows us to factor in, to a degree, the effect of interest rate increases when working out how much you may be able to afford.

Calculations are not a loan or other product approval. Applications for credit are subject to credit approval and satisfactory security and minimum deposit requirements. Other criteria also apply. Conditions apply to all loans and other products. Full terms and conditions will be set out in our loan or other product offer, if an offer is made.

Fees and charges are payable. Interest rates are subject to change. The calculations do not take into account fees, charges or other amounts that may be charged to your loan or other account (such as establishment fees or stamp duty). Lender's Mortgage Insurance may apply. Any of these additional amounts will increase repayments under the loan.

As this information has been prepared without considering your objectives, financial situation or needs, you should consider its appropriateness to your circumstances before acting on it. You should obtain financial and taxation advice from a suitably qualified and experienced professional adviser before making a financial decision.
