How is Affordability Calculated?

Income Multiple

Lenders typically offer between 4 and 5.5 times your annual gross income. Single applicants and couples are both assessed this way.

Affordability Checks

Beyond income multiples, lenders conduct detailed affordability assessments including stress tests at higher interest rates.

Other Income

Bonuses, commission, and overtime can sometimes be included, though lenders may only count a percentage of these.

Existing Commitments

Credit card balances, loans, and other financial commitments will reduce the amount you can borrow.

Frequently Asked Questions

How much can I borrow for a mortgage?

UK lenders typically allow you to borrow between 4 and 5.5 times your annual salary. The exact multiple depends on your credit score, existing debts, monthly expenses, and the lender's criteria. Use our calculator to estimate your borrowing range.

Do mortgage lenders consider both incomes?

Yes, if you're buying with a partner or spouse, lenders will consider both incomes when calculating affordability. They typically apply the same income multiple (4-5.5x) to your combined annual salaries.

What affects my mortgage affordability?

Mortgage affordability is affected by your annual income, existing debts (credit cards, loans, car finance), monthly outgoings, credit score, employment type, and the deposit amount. Lenders also stress-test your ability to afford higher interest rates.

Can I borrow more with a larger deposit?

A larger deposit reduces the loan-to-value (LTV) ratio, which can help you access better interest rates and may improve your chances of approval. However, it doesn't directly increase the income multiple lenders use for affordability.

Should I speak to a mortgage broker?

Yes, a mortgage broker can provide more accurate borrowing limits based on your specific circumstances. They have access to the whole market and can find lenders that offer higher multiples or are more flexible with affordability criteria.
