How Much Can I Borrow on a $100k Salary in Australia?
Updated 31 Aug 2025 · 6–8 min read
Quick answer: On a $100k salary, borrowing power is often around $500k–$650k for a single with low debts. With dependants/higher expenses, it may be closer to $400k–$500k.
What Lenders Consider
- Net income after tax (take-home on $100k is roughly ~$74k/yr).
- Living expenses (HEM), which increase with dependants.
- Existing debts (credit cards, personal loans, car finance).
- Assessment rate buffer (often ~3% above current variable rates).
Worked Example
- Gross income: $100,000
- Approx. net after tax: $74,000
- Living costs (single, no kids): ~$25,000
- Surplus for repayments: ~$49,000
At a stressed assessment rate, that surplus may support a loan around ~$550,000.
Ways to Lift Your Borrowing Capacity
- Reduce credit card limits and pay down debts.
- Increase your deposit to lower LVR (may avoid LMI).
- Trim recurring expenses and subscriptions.
- Consider applying jointly if appropriate.
