How it works
How to use it
- Enter your gross annual income and the savings you have available.
- Add the interest rate you expect and the loan term.
- Check the share of income, buying costs and loan-to-value ratio for Australia and change them if needed.
- See the maximum price, the breakdown and which limit applies.
How it is calculated
Two prices are calculated and the lower one applies. By income: the loan whose repayment, at your rate plus 3 percentage points, is the chosen share of your gross income, plus your savings, minus buying costs. By savings: the price at which your savings exactly cover the deposit and the costs. The percentages are general values for Australia. A second applicant's income is added to yours; other debt payments count the way the country's rule counts them.

About this calculator
How it’s calculated
Two limits decide how much you can borrow. The first is serviceability: the repayment, tested at your rate plus 3 percentage points, should fit within the chosen share of your gross income (30% here, a general value). The second is the deposit: with an 80% loan, 20% of the price plus the buying costs come from your savings. The calculator works out the price each limit allows and shows the lower one.
What lenders in Australia look at
Besides the buffer, lenders assess your living expenses, other debts, credit card limits and dependants, and some apply their own minimum assessment rate. Joint applicants can usually add their incomes together.
Buying costs in Australia
Stamp duty depends on the state and the price, and many states offer concessions or exemptions for first-home buyers. Conveyancing, inspections and loan fees come on top. The 4% filled in is a general value: check it with your lender or broker.
Frequently asked questions
What is the serviceability buffer?
APRA expects lenders to assess whether you could still afford the loan at an interest rate at least 3 percentage points above the rate you'll actually pay. The calculator tests your income limit at that higher rate; the repayment shown is at your real rate.
How much deposit do I need?
Usually 20% of the price to avoid lenders mortgage insurance, plus stamp duty and other buying costs. Some lenders accept smaller deposits with insurance.
Why might my lender offer less?
Lenders look at your actual living expenses, other debts, credit card limits and dependants. That can mean less borrowing power than here.
What if we buy as a couple, or I already pay other loans?
Under «More options» you can add the second applicant's income, which is added to yours, and what you already pay each month for other loans, cards or leasing. In Australia, the limit we apply only counts the mortgage: your other debts don't change it, but the lender will review them and may lend you less.
