Annette and Katrina are absolutely brilliant. We have used them for our mortgage renewal and recent house purchase and delivered both times. We got their details from a friend and we constantly recommend them as nothings too much to ask and they really take care in your individual process. 10/10 service and 10/10 people. Thank you!

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.
