MAB have been fantastic and helped us so, so much. We struggled to get a mortgage offer elsewhere with our existing debt, but MAB got us one now problem. We have had extremely fast communication and have never had to chase emails. We have always received speedy responses and they updated us every single step of the way. We couldn't recommend them more, especially Ben, who we have dealt with the most.

Prior to beginning this process applying for a mortgage seemed like an incredibly daunting process. Working with Chris Cargill at First Mortgage (the mortgage advice bureau), he made the whole the experience so much more attainable and much less intimidating. The support that the team provided and helped us with was invaluable and such a positive experience for us.

Dan was helpful all the way through. We first started this process last year and he's kept in touch through the whole thing. He's been really good at explaining everything and taking us through our options. It's made the process 10 times easier with his help.

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.
