Mortgage affordability calculators

How much can I afford to borrow as a mortgage? Our calculators give you a rough idea of what you might be able to borrow from us to buy a home, and what your monthly and total mortgage payments could be for various types of mortgage. 

How do you assess what I can afford as a mortgage? When you apply for a mortgage, we’ll ask for the number of applicants, what their income is and whether you’re first-time buyers, remortgaging or buying a new or second home. We’ll also ask about your regular spending, such as payments for credit and store cards, loans, overdrafts, maintenance and your pension. We won’t ask about groceries, travel and utility bills.
