How do I calculate what I can afford in the UK?

Calculate affordability by subtracting your monthly expenses from your monthly income. A general rule is to keep total debt payments below 45% of your gross income. For mortgages, lenders typically cap payments at 35-45% of income. Use our calculator for personalized results.

What is the 28/36 rule for affordability?

The 28/36 rule states that your housing costs should not exceed 28% of your gross income, and your total debt payments should not exceed 36%. UK lenders use similar guidelines for mortgage affordability, with most limiting housing costs to 35-45% of income.

How do UK lenders check affordability?

UK lenders check affordability using income multiples (3-5x salary) and stress tests (whether you can afford payments at higher interest rates). They also consider your monthly expenses, debts, and credit history. The Financial Conduct Authority (FCA) requires strict affordability checks.

What is a good debt-to-income ratio in the UK?

A good debt-to-income ratio in the UK is below 45%. This means your total monthly debts (mortgage, loans, credit cards) should be less than 45% of your gross monthly income. A ratio below 30% is considered excellent and improves your chances of loan approval.

Income: Net monthly income after tax
Expenses: Regular outgoings (rent, bills, debts)
Debt-to-Income Ratio: Total debts ÷ Gross income
Stress Test: Can you afford payments if rates rise?
Credit Score: Financial history and reliability

DTI is the most important affordability metric:

Calculation: (Total Monthly Debts ÷ Gross Monthly Income) × 100
0-30%: Excellent - lenders will approve easily
30-45%: Good - manageable for most lenders
45-60%: Warning - may struggle to get approved
60%+: High risk - focus on reducing debt
