How much can I borrow?

If you're a first time buyer beginning the search for your perfect first home, or a homeowner thinking about remortgaging to Newcastle Building Society, you can use our simple mortgage affordability calculator to get an idea of how much we may be willing to lend you.

Affordability Calculator

Our affordability calculator is a quick and easy way of seeing how much you may be able to borrow from us, before you speak to one of our qualified mortgage advisers. The amount quoted by our calculator is only for guidance and is not an offer of a mortgage, as we'd need to take you through a more detailed set of questions to give you a firm figure, but it will give you an indication of how much mortgage you could afford.

How much mortgage can I borrow?

The amount of mortgage that you can afford to borrow - your 'affordability' - is calculated based on several factors. Our mortgage affordability calculator will give you an estimated quote based on the amount you want to borrow and the property value (if known) or the amount of deposit you have, and the term over which you want to borrow. You can also enter your preferred mortgage product rate - you can use our mortgage comparison tool to compare the mortgage rates we currently have available.

To get a personalised quote, known as a 'Decision in Principle' or DIP, and a formal mortgage offer, you would then need to speak to one of our qualified mortgage advisers who will calculate exactly how much we would be willing to lend you. This is done by assessing your individual circumstances, including your income, your regular financial commitments, and your household and lifestyle expenditure.

If you're just starting out on your journey to buying a first home, our 'How much can I borrow?' page for first time buyers explains in more detail how we would calculate your borrowing affordability, including your mortgage deposit.

On the other hand if you already own a home but are considering a remortgage to us, our Remortgaging FAQs page explains the lending criteria that you may need to meet in order to qualify for a remortgage.

Should you wish to make a formal application for a mortgage or remortgage with Newcastle Building Society, one of our qualified mortgage advisers would be pleased to speak with you. Call us now on 0345 606 4488 or book an appointment at your local branch to begin your mortgage application process.

Frequently asked questions about our mortgage affordability calculator

If you have any questions about the quote given by our mortgage affordability calculator, you may find the answer below. If not, just give us a call or visit your local branch where we would be happy to help you.

Can I save the information I've entered into the calculator?

Unfortunately, it's not possible to save the information that you've entered into our affordability calculator, but you can print a copy of your estimated quote for your reference.

Does my quote apply if I want an interest-only mortgage?

Currently, we only accept mortgage applications on a repayment basis. We do not offer mortgage loans on an interest-only or part interest-only basis at this time as they do not meet our lending criteria.

Is the quote shown by your calculator guaranteed?

Our mortgage affordability calculator will only give you an indication of how much you could borrow from Newcastle Building Society. We'd need to go through a more detailed set of questions with you personally in order to give you a formal mortgage offer - you can call us, or make an appointment at your local branch to begin your mortgage application.

I already have a mortgage with Newcastle Building Society - does the calculator apply for further advances?

You can use our affordability calculator for new mortgages only. If you are interested in a further advance, you'll find more information about borrowing more on your mortgage here, or you can discuss this with us over the phone or in branch.

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