What is a mortgage calculator? 

It’s a tool that gives you an estimate of how much you could borrow from us or what your monthly repayments and other costs might be, for a mortgage in the UK.

We have different calculators that can help you in different ways – each calculator does something slightly different.

Who is a mortgage calculator for?  

It’s for you if you’re a first time buyer, you’re looking to remortgage, move or buy an additional home, or you’re a buy-to-let landlord. 

What information do I need to use a calculator and how do you decide what I can afford?

When you apply for a mortgage or use our calculator, we’ll ask you for information like

  • How many people are applying
  • Your income
  • How much you regularly spend – on things like your credit or store cards, loans, overdrafts, maintenance and pension
  • Why you’re applying – for example, buying your first home, moving home, or buying a second home

We won’t ask about groceries, utility bills or travel.

How much can I afford to borrow?

Our calculators give you a 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 different types of mortgages.
