Otis and Katie were fantastic throughout the entire mortgage process. They were both incredibly helpful, professional and responsive, keeping us updated at every stage. They were able to find us an improved mortgage rate compared with the one that was originally agreed, which was a fantastic result and made a real difference. They were always on hand to answer our questions, chase updates when needed and make sure we understood what was happening. Their knowledge, attention to detail and commitment gave us real confidence throughout the process.

I worked with Paula and she was helpful, thoughtful and even saved us money. A couple of different options were provided for us to discuss and a very simple and straight forward process with excellent communication along the way.

James was really helpful and spent a lot of time explaining all the information about porting our Mortage and everything to do with affordability, mortgages rates and even life insurance options. He still keeps us updated on the rates and the progression of our application which had just been approved! Felt happy and reassured after our meeting will definitely keep with James going on with our future re-mortgaging ect . Thankyou!

Adam was really great at walking me through the process and explaining everything as it happened. I had one meeting with him, but needed a follow-up to finalise the mortgage, and he was happy to do that. I would highly recommend Adam.

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.
