We have been extremely impressed by the service that MAB has provided. Our mortgage broker Nigel Trott went above and beyond when striving to secure us our mortgage application, based on our personal circumstances. Nigel provided an absolutely fantastic service and we were so impressed with his work. He was extremely knowledgeable and provided excellent advice. We met with him face to face and found his professionalism and friendly manner really outstanding. Nothing was too much trouble and he did all he could to make the process as stress free as possible for us. He replied to all our queries in a very timely manner via email and telephone calls. He kept us up to date throughout the process. It is clear to see that Nigel is extremely passionate about what he does and has many years of experience to reflect that. We would have no hesitations in recommending his services to friends and family.

Questions about our mortgage calculators

What are mortgage calculators?

Our mortgage calculators are digital tools designed to help you estimate your potential borrowing power and mortgage repayments. They’re a handy way of helping you understand your financial commitments before speaking to one of our expert advisers.

Is using our mortgage calculators right for you?

Our free digital tools are designed for anyone looking to purchase a home. This means if you’re a first time buyer, someone looking to move home, or you’re on the hunt for a remortgaging deal, our calculators are for you.

What information do I need to use a calculator and how does it work?

We have several handy calculators for borrowing, mortgage repayments, remortgaging, and Stamp Duty.

These all require two to three pieces of key information, which the calculators then use to provide you with an indication on what the potential costs could be.

Please remember that lenders also take a close look at other factors. These will include your credit score, financial history, and personal expenditures. All of this information will affect the actual calculation of your mortgage and monthly repayments.

Our mortgage calculators empower you to be as informed as possible when it comes to finding the right mortgage deal for you and your circumstances.

What are the next steps after using the calculators?

If you’d like to discuss moving forward with your homebuying journey, our expert advisers are here to help provide guidance and answer any questions you may have. You can also download the My MAB app, which allows you to save, plan, and track every stage of buying your new home and beyond.
