FAQs about our mortgage calculators

How much mortgage can I afford?

Our mortgage calculator can help you get an initial indication of how much money you may be able to borrow towards the purchase of a property. It also helps you understand what your potential monthly repayments could be.

Does the mortgage calculator impact my credit score?

No, using our mortgage calculator tool or getting an Agreement in Principle won't have any impact on your credit score. We would only conduct a full credit check with credit reference agencies if you went on to formally apply for a mortgage with us.

When should I use the mortgage calculator?

You can use our mortgage calculator as many times as you like, whenever you like. Generally, it makes sense to use it at the start of your journey to purchase a property, or if you are looking to remortgage to us. You can use it to get an initial understanding of what you may be able to afford, monthly repayments and potential interest rates.
