The amount of house you can afford depends on more than your annual salary. Your take-home pay, living expenses, debts, deposit, interest rate and lender assessment all influence a realistic property budget.
How Much House Can I Afford on My Salary in Australia?
There is no single salary multiple that accurately determines how much every Australian can afford to borrow. Two people earning the same salary may receive very different outcomes because their expenses, debts and household circumstances differ.
A useful starting point is to calculate the repayment you could manage without leaving your everyday budget under pressure.
Affordable repayment = Take-home income − Living expenses − Debt repayments − Savings commitments − Safety buffer
This produces a personal repayment allowance, not a guaranteed borrowing amount. A lender will conduct its own serviceability assessment using its lending policy and verified financial information.
Start with the simple salary calculator to estimate salary after income tax and Medicare levy under the calculator’s available assumptions.
Start With Take-Home Pay, Not Gross Salary
Gross salary is the amount earned before tax and other deductions. Mortgage repayments must be made using money that remains after those amounts have been removed.
If an employee earns A$100,000, they should not treat A$8,333.33 of gross monthly salary as fully available for housing. Their actual monthly deposit will be lower after PAYG withholding, Medicare levy and any other applicable deductions.
The take home pay calculator can provide an estimated weekly, fortnightly, monthly or annual net amount. Actual payroll results can differ because of HELP repayments, tax offsets, salary sacrifice and employer-specific deductions.
Use a conservative income figure if overtime, bonuses or commissions are irregular. A lender may not assess every income source in the same way.
Calculate Your Available Monthly Repayment
Assume a household receives A$6,200 in combined monthly take-home income. Its regular monthly commitments are:
- Living expenses: A$2,700
- Car and personal-loan repayments: A$650
- Insurance and annual-cost provisions: A$350
- Regular savings target: A$500
- Financial buffer: A$400
The remaining amount is:
A$6,200 − A$2,700 − A$650 − A$350 − A$500 − A$400 = A$1,600
This household may decide that approximately A$1,600 is available for housing repayments. However, it must consider whether current rent is already included in the living-expense figure. Counting rent twice would understate available cash, while removing expenses that continue after buying would overstate it.
The guide explaining how to budget fortnightly pay in Australia can help convert differently timed income and bills into comparable amounts.
Convert an Affordable Repayment Into a Loan Estimate
Mortgage repayments generally depend on four main inputs:
- Loan principal
- Interest rate
- Loan term
- Repayment frequency
A larger loan or higher interest rate increases repayments. A longer term generally reduces each scheduled repayment but can increase total interest paid over the life of the loan.
For example, a principal-and-interest loan of A$500,000 at 6% per year over 30 years has an estimated monthly repayment of approximately A$2,998, assuming the rate remains unchanged and no fees are added.
This does not mean a household earning a particular salary will automatically qualify for that loan. Compare the repayment with verified take-home income and ongoing expenses using the Australian mortgage calculator.
Calculator results are estimates rather than lender quotes or approval decisions. Actual loan products may include changing rates, fees and other conditions.
Why Lenders Test Higher Repayments
A lender does not necessarily assess an application only at the advertised loan interest rate. It may test whether the borrower could continue making repayments if rates increased.
In May 2026, APRA confirmed that the mortgage serviceability buffer remains 3 percentage points above the loan rate for regulated lenders.
A loan priced at 6%, for example, may therefore be assessed using a rate of at least 9%, subject to the lender’s complete methodology and applicable requirements.
This helps explain why a repayment that appears affordable in a basic calculator may not produce the same borrowing amount during a lender assessment.
How Your Deposit Affects the Property Budget
Borrowing capacity and property purchase price are related but different.
A simplified purchase-price estimate is:
Potential property price = Available deposit + Loan amount
If a buyer has an A$100,000 usable deposit and qualifies for a A$500,000 loan, the simple combined amount is A$600,000.
However, not all saved money should automatically be assigned to the deposit. A buyer may also need funds for stamp duty, conveyancing, inspections, moving, loan fees and an emergency reserve. Lenders mortgage insurance may apply when the deposit does not meet a lender’s required loan-to-value ratio.
Costs and concessions vary by state, territory and buyer eligibility. They should be researched separately before setting the final purchase limit.
Expenses and Debts That Reduce Affordability
Lenders may consider regular household spending, dependants, credit cards, personal loans, car finance, existing mortgages and other commitments.
A credit card can affect an assessment even when the balance is repaid regularly because the available limit may represent potential future debt. Reducing a limit should only be considered when it suits your genuine financial needs.
Student debt may also affect available cash flow or lender calculations. Do not hide or deliberately understate expenses on an application.
Use the salary budget calculator to organise the income and expense categories supported by that tool. Review actual bank transactions so the budget reflects real spending rather than optimistic estimates.
Prepare for Changes After Buying
A repayment that fits today may become difficult after an interest-rate rise, income reduction or major expense.
Test the budget using a higher repayment and consider costs that renters may not currently pay, including council rates, building insurance, repairs, owners corporation fees and property maintenance.
Keep a reasonable buffer after settlement instead of using every available dollar for the deposit. The appropriate amount depends on job security, household size, property condition and other personal factors.
Buyers deciding whether to preserve cash or make extra super contributions can also compare salary sacrifice vs after-tax super contributions. Money contributed to super is generally preserved and may not remain available for an ordinary property purchase, except where a specific release rule applies.
Frequently Asked Questions
Q1: Can I calculate borrowing power from salary alone?
A: No. Salary is only one factor. Expenses, debts, dependants, deposit, interest rate and lender policies also affect borrowing capacity.
Q2: Should I use gross or take-home pay?
A: Use take-home pay when testing your household cash flow because repayments are made from money available after deductions.
Q3: Does a larger deposit increase borrowing power?
A: A larger deposit can reduce the required loan and loan-to-value ratio, but lenders still assess whether income can support repayments.
Q4: Why is a lender result lower than a calculator estimate?
A: Lenders may apply a serviceability buffer, assess expenses differently and consider debts, credit limits and income reliability.
Q5: Does the calculator include stamp duty and purchase costs?
A: Check the calculator’s displayed inputs and results. Do not assume stamp duty, legal fees, inspections, insurance or lender fees are included unless expressly shown.
Q6: Is an affordability estimate a loan approval?
A: No. It is a planning estimate. Only a lender can assess an application and decide whether to offer a loan.
