What is a home loan borrowing calculator and how to use it
A home loan borrowing calculator estimates how much a lender may loan you based on your financial situation. It’s an essential first step for setting a realistic property budget in Australia. It considers:
Income: Salary, bonuses and rental income.
Debts and expenses: Credit cards, loans and living costs.
Dependents: The more dependents, the lower your capacity.
Loan term and rate: Usually based on standard market assumptions.
The result is an estimate, not pre-approval. Every lender applies unique criteria. Use it to guide expectations, but rely on a broker for an accurate figure. Borrow slightly less than your maximum to maintain a financial buffer.

Key factors that impact borrowing power
Your borrowing limit is based on a full risk assessment, not just income. Major factors include:
Debt to Income Ratio (DTI): Lower debt boosts capacity.
Living Expenses (HEM): Cutting discretionary spending before applying helps.
Interest rate buffer: Lenders test affordability at roughly 3% above current rates.
Dependents: Each dependent increases assessed expenses, reducing capacity.
If this feels complex, HeyNest connects you with brokers who compare your detailed financial profile against different lenders’ rules to find your true borrowing power.

Frequently asked questions
Is the borrowing amount from a home loan borrowing calculator guaranteed?
No, it is an estimate. Your guaranteed borrowing limit comes from a formal pre-approval from a lender.
How often should I use the home loan borrowing calculator?
You should use it whenever your financial circumstances change significantly (e.g., pay rise, new debt or new dependent).
Does the calculator include fees like stamp duty?
Usually no, the calculator shows the maximum loan amount. You must separately factor in associated purchase costs like stamp duty and legal fees.
