Tony is always so helpful. He's so 'on it' from start to finish. Takes all the stress out of remortgaging!

Concise and friendly communication. Appointments were informative and easy to understand, no jargon. Efficient and straight forward. Friendly reception. All that was discussed was clearly benefical to my end goal. Steven Tempest is a thorough and understanding advisor with a very personable nature and approach.

The staff were clear with the information and the advise provided. They even simplified some of the terminology used by the bank when i didn't fully understand. The staff went above and beyond with providing assistance.

Fantastic service, I would highly recommend. My broker (Robbie) was very helpful and supportive, despite me having a few challenging circumstances which made a little more work for him. He found me a very good mortgage offer, and supported me through the whole process. This was really important to me as a first time buyer navigating a system I haven't had any experience of before. He took the time to explain everything, answer any questions I had and reassure me if there were any concerns.

Mike has done two mortgages for me now. I wouldn't hesitate to use him again. Takes all the hassle and stress out of it and gives clear sound advice. Even with comparison sites it doesn't explain the full costs like he does helping you saves £1000s over all.

Cannot thank Callum Weir enough for all his help with supporting us getting our first mortgage offer. We went into this blind as first time buyers and Callum assisted us so well, kept us in the loop and was so helpful throughout the process and were so happy with how streamline and stress free the process was. 5* definitely recommend. Thanks again!

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.
