Your mortgage affordability questions answered
What does a mortgage affordability calculator show?
A mortgage affordability calculator estimates how much you may be able to borrow based on the information you enter.
It can give you a rough borrowing range, but it does not confirm what a lender will offer.
How do lenders work out mortgage affordability?
Lenders usually look at your income, spending, debts, dependants, deposit, credit history and mortgage term.
They may also stress test affordability to check whether the mortgage could remain manageable if rates or circumstances change.
Is mortgage affordability based only on salary?
No. Salary is important, but lenders also review wider affordability.
Overtime, bonuses, commission, self-employed income, benefits, debts, childcare costs and regular commitments can all affect the final borrowing amount.
Can different lenders offer different amounts?
Yes. Different lenders use different affordability models and criteria.
One lender may offer more or less than another depending on how they assess your income, commitments, credit profile and deposit.
Does my deposit affect affordability?
Yes. Your deposit affects your loan-to-value, which can influence the lenders, rates and products available.
A larger deposit may improve your options, although affordability will still depend on your income and commitments.
Is an affordability calculator the same as an Agreement in Principle?
No. An affordability calculator gives an estimate.
An Agreement in Principle is a lender’s initial indication of what they may be willing to lend, usually based on more detailed information and sometimes a credit check.
Your results are for guidance only
Your results are for guidance only and are based on the information you enter. They are not a mortgage offer, approval in principle or financial advice.
Your actual borrowing amount may depend on your income, spending, debts, dependants, deposit, credit profile, employment status, property type, mortgage term, lender criteria and wider circumstances.
Different lenders may assess affordability in different ways. You should check your options before making an offer or applying for a mortgage.
Your home may be repossessed if you do not keep up with repayments on your mortgage.
