The only reason I went with MAB rather than Trinity (who I was speaking to first) was because the handler, Louis, at MAB is ace. He was factual and professional and got the job done, listening to exactly what I was looking for. He also seemed like a lovely person. (The Trinity guy was a pushy bully trying to fear-monger a deal out of me).

I’ve been using Andrew Rowe and his team at MAB for many years, and the service has been consistently excellent. They are knowledgeable, professional, and always go the extra mile to make sure everything is handled smoothly. Communication is clear and timely, and they take the stress out of what can often be a complicated process. Their fast turnaround really sets them apart, and it’s great to have a team you can trust year after year. I wouldn’t go anywhere else and highly recommend them.”

The help and advice me and my husband received has been very good . We are very inexperienced with this and have lots of questions, probably quite trivial or stupid but ollie always answers and never makes us feel like they are stupid .

Really proactive, kept me fully informed of the process and possible way to minimise impact of fees. I am confident that I have the best deal available without having to do any of the hours of comparison. My advisor has been brilliant with managing the process and keeping me informed.

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.
