Outstanding service from Ben – highly recommended! I can’t thank Ben enough for all his help throughout our mortgage journey. He was professional, knowledgeable and extremely supportive from start to finish. Our mortgage application wasn’t the simplest, but Ben was always there to answer our questions, keep us updated and guide us through every stage. He worked incredibly hard to find the right lender for us and ultimately secured our Halifax mortgage offer, which was a huge relief and a very important milestone for us. What really stood out was Ben’s dedication, communication and determination. He made what could have been a very stressful process feel much easier. Thank you so much, Ben, for all your hard work. We genuinely appreciate everything you’ve done for us and would have no hesitation in recommending you to anyone looking for a mortgage broker. 5-star service all the way! ⭐️⭐️⭐️⭐️⭐️

Since starting the mortgage process 5 years we have been guided and supported throughout. We get monthly updates and 6 months before our mortgage was due to be renewed, we were found an affordable deal. Pointed towards other free advice and are always on hand anytime. As long as you have saving with The Nottingham building society. They support you all the way. At no extra cost.

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.
