How It Works
Lenders Look at Income and Spending Together
Affordability is about what is left after your regular costs, not just your salary.
- ✓Income: salary, overtime, bonus and other income that can be counted
- ✓Commitments: loans, cards, car finance and student loans
- ✓Living costs: childcare, bills, travel and everyday spending
- ✓Stress test: lenders check you could still pay at a higher rate
