Affordability Calculator

Find Your Budget

Before you start viewing properties, it helps to know roughly what you can afford.

This affordability calculator gives you a quick, no-obligation estimate of how much you might be able to borrow; based on your income, your deposit and a few details about your purchase.

It’s a guide to get you started, not a formal mortgage offer or an Agreement in Principle. Use it to get a feel for the budget to keep in mind while you search, then speak to one of our advisers when you’re ready to look at your options in more detail.

How your budget is calculated

The calculator uses a few standard figures to give you an indicative result:

  • Borrowing is based on an income multiple - many lenders use around 4 to 4.5 times your annual income as a starting point, though this varies between lenders and depends on your circumstances.
  • Monthly repayments are estimated using a 5% interest rate over a 35-year term, so you can see a realistic monthly figure.
  • Stamp duty is calculated for England and Northern Ireland (SDLT).

Your actual figures will depend on a full review of your income, outgoings and credit history , which is where an adviser comes in.

Ready to take the next step?

Once you’ve got an idea of your budget, an adviser can confirm what you could borrow, talk through the options and help you arrange an Agreement in Principle when the time is right. There’s no obligation - just a conversation to help you plan your next move.

FAQ's


How much can I borrow for a mortgage?

As a rough guide, many lenders will consider lending around 4 to 4.5 times your annual income, though this varies depending on the lender, your deposit and your wider financial situation. The calculator above uses this kind of figure to give you an indicative budget. A full assessment with an adviser will give you a clearer picture.


How much deposit do I need?

Most residential mortgages need a deposit of at least 5% to 10% of the property’s price. A larger deposit can open up more options. The calculator lets you enter your deposit so you can see how it affects your budget.


Is this the same as an Agreement in Principle?

No. An Agreement in Principle (sometimes called a Decision in Principle) is a statement from a lender, based on an initial credit check, indicating how much they may be willing to lend. This calculator doesn’t run any credit check or contact a lender — it simply gives you an indicative budget to start with. When you’re ready, an adviser can help you arrange an Agreement in Principle.


Will using this calculator affect my credit score?

No. The calculator doesn’t carry out a credit check or share your details with a lender, so it has no effect on your credit score. It’s purely an indicative guide.


What’s the difference between capital & interest and interest-only repayments?

With a capital and interest (repayment) mortgage, your monthly payment covers both the interest and a portion of the amount you borrowed, so the balance reduces over time. With interest-only, you pay just the interest each month and the original amount borrowed remains outstanding at the end of the term. The calculator shows both so you can compare.


How accurate are the results?

The results are indicative and for guidance only. They’re based on standard assumptions rather than a full review of your finances, so your actual borrowing and repayments may differ. For figures tailored to your situation, speak to one of our advisers.


Your home may be repossessed if you do not keep up repayments on your mortgage.
