Calculate how much you could borrow

A great place to start when thinking about buying a home, is finding out how much you may be able to borrow.

You can use our mortgage calculator open_in_new to get an idea of what we could lend you based on your income.

While this isn’t a full mortgage affordability calculator and is only a guide, whether you're a first time buyer, moving home or remortgaging, it can help you understand what might be afforable and feel more confident as you explore your mortgage options.

What you'll need

The calculator will ask you for a few details to give you an indication of what you might be able to borrow.

  • Your income: Your yearly income before tax and deductions, and your net monthly income after tax deductions.
  • Extra monthly expenses: This includes any loan or credit card payments, and things like childcare, education fees, existing insurance policies and private pensions. Don’t include groceries, utility bills, fuel and
 travel.
  • Your dependants: The number of children or adults who you financially support. Students who don’t live at home may still be considered dependents if you support them financially.
  • Your deposit: How much you've got saved for a deposit. You can leave this out if you're not sure just yet - the calculator will suggest how much you'll need as a minimum.
  • The mortgage term: How long you want the mortgage to be for. This can be between 5 and 40 years.

Once you submit your details, the calculator will show you an idea of the amount you could borrow and your loan to value (LTV) ratio.

It's important to note that the estimate provided doesn't take into account your household expenditure, individual circumstances or credit history. Once you're ready, you can get a more personalised indication of what we could lend you by getting a Decision in Principle (DIP) open_in_new.

Common questions

Lenders don’t just look at your income and regular outgoings when they assess how much you can borrow. They also look at:

  • Existing debts and bill payments e.g. credit cards and loans.
  • Any other financial commitments e.g. childcare and commuting costs.
  • How much deposit or equity you have in your home.
  • Your credit score.
  • How changes to interest rates could affect your monthly payments.

It’s about making sure your repayments feel manageable and comfortably fit into your life without stretching you too thin. This helps give you peace of mind that you can afford the mortgage not just today, but for years to come.

No, our online mortgage calculator won’t affect your credit score. We don’t do any credit checks at this stage as the calculator just gives you an idea of what you could borrow. If you apply for a mortgage with us, we'll then do a full credit check, which may impact your score.

What is a credit score and how does it work?

There are a few things that lenders look at that will determine how much you can borrow for a mortgage, such as:

  • Your income
    Most lenders offer roughly 4 to 5 times your annual income.
  • Your outgoings
    Lenders want to check that there's enough room in your budget to afford the monthly mortgage payments.
  • Any existing debt
    Debt increases your outgoings and so the more debt you have, the less you'll be able to borrow.
  • Your credit score
    A good credit history can help you borrow more. It shows you're responsible with payments.
  • Deposit size
    The more you save, the better. A bigger deposit gives lenders more confidence.
