How much can I borrow on a $100,000 salary in Australia?

On a $100,000 gross salary with typical living expenses and no other debts, you may be able to borrow approximately $450,000–$550,000. Lenders assess your borrowing capacity at a rate 3% above your loan rate (the APRA serviceability buffer). Use this calculator for a personalised estimate.

What is the APRA serviceability buffer?

APRA requires all Australian lenders to assess your ability to repay a mortgage at least 3% above the loan's interest rate. For example, if your loan rate is 5.50%, the lender tests you at 8.50%. This reduces your maximum borrowing capacity but protects you from rate rises.

Do both incomes count when applying for a joint home loan?

Yes. Most lenders include both applicants' incomes in a joint application. However, they will also assess both applicants' liabilities and living expenses. This calculator allows you to enter a second income.

How does a credit card affect my borrowing power?

Lenders assess your credit card limit — not just your balance — as a potential liability. APRA guidelines require lenders to assume you could draw the full limit and repay it at 3.8% per month. A $10,000 credit card limit can reduce your borrowing power by approximately $40,000–$50,000.
