How Much Can I Borrow for a Home Loan in Australia?
One of the first questions buyers ask when thinking about purchasing a property is: “How much can I borrow?”
Borrowing capacity determines the price range you can realistically consider when buying a home. While income plays an important role, lenders look at several factors when assessing how much they are willing to lend.
Understanding these factors can help you plan your property search and avoid surprises during the loan application process.

What Determines Borrowing Capacity?
Lenders assess a range of financial factors to determine how much you can borrow.
The most important include:
• Your income
• Your living expenses
• Existing debts
• The number of dependents you have
• Interest rate buffers applied by the lender
These factors help lenders determine whether you can comfortably manage the loan repayments.
Income and Employment
Your income is the starting point when lenders calculate borrowing capacity.
Banks typically consider:
• Salary or wages
• Overtime or bonuses (sometimes partially)
• Rental income
• Investment income
Stable and consistent income generally results in stronger borrowing capacity.
Lenders may also assess how long you have been employed in your current role or industry.
Living Expenses
Banks assess your regular living expenses to determine how much income is available to repay a home loan.
Typical expenses considered include:
• Groceries
• Utilities
• Transport
• Insurance
• Entertainment and subscriptions
Lenders compare your declared expenses with typical household spending benchmarks to ensure the numbers are realistic.
Higher expenses can reduce borrowing capacity.
Existing Debts
Existing debts are also included when calculating borrowing capacity.
Examples include:
• Car loans
• Personal loans
• Credit cards
• Buy Now Pay Later accounts
• HECS or HELP debts
These commitments reduce the amount of income available to service a mortgage.
Credit Card Limits
One detail many buyers overlook is that lenders assess credit card limits, not just the balance.
For example:
A credit card with a $10,000 limit may reduce borrowing capacity even if the balance is zero.
Reducing unused credit card limits before applying for a home loan can sometimes improve borrowing capacity.
Banks also review spending habits when assessing loan applications.

Interest Rate Buffers
Lenders do not assess loans using the current interest rate alone.
Instead, they apply a buffer rate to ensure borrowers could still afford repayments if interest rates increase in the future.
This means borrowing capacity may appear lower than expected even if current repayments look affordable.
Example Borrowing Scenarios
Borrowing capacity varies depending on income, expenses, and lender policies. The examples below illustrate how income can affect borrowing ranges.
Single income example:
Income: $80,000
Estimated borrowing range: around $350,000 to $450,000
Couple income example:
Combined income: $150,000
Estimated borrowing range: around $700,000 to $900,000
Higher income example:
Combined income: $200,000
Estimated borrowing range: around $1,000,000 or more depending on expenses and debts.
These ranges vary significantly depending on the lender and financial situation.

There are several steps buyers can take to increase borrowing capacity before applying for a loan.

Small changes can sometimes increase borrowing power significantly.

Understanding how borrowing capacity works can help buyers set realistic expectations when searching for property.
Getting professional guidance early can also help ensure you apply with lenders that best suit your financial situation.
