Understanding Mortgage Stress: The Current Reality
What is Mortgage Stress?
Mortgage stress occurs when your home loan repayments exceed 30% of your gross household income. This threshold indicates financial strain that can affect your ability to:
- Cover essential living expenses like groceries and utilities
- Build savings for emergencies or unexpected costs
- Service other debts like credit cards or personal loans
- Maintain your current lifestyle and discretionary spending

|---|---|---|---|
| May 2022 | 0.1% | 3.2% | $2,108 |
| Peak (2023) | 4.35% | 7.1% | $3,360 |
| Current (2025) | 3.85% | 6.6% | $3,210 |

- • Current testing rates: 7.5-8.5% depending on lender
- • Serviceability buffer: 3% above current rates
- • Assessment includes: All debts and realistic living expenses
Personal Stress Testing Scenarios
Beyond bank requirements, you should test your own mortgage under these scenarios:
Financial Stress Tests

- • Expense increases: Children, medical costs
Economic Downturn
