Chloe Wilkinson was recommended to me by my brother and sister-in-law, who couldn't speak highly enough of her, and now I completely understand why. From start to finish, Chloe was professional, knowledgeable, and always willing to go the extra mile. She was helpful throughout the entire process, always kept me informed, and made sure I understood every step along the way. Her communication was excellent, and she explained everything clearly and patiently, making what can be a complicated process much easier to navigate. When we experienced a little setback, I was naturally very stressed, but Chloe remained calm, reassuring, and confident that everything would be okay. Although the process took a little longer than expected, she continued to support me, kept me updated regularly, and worked tirelessly to help move things forward. What stood out most was her professionalism and dedication. She was always responsive, approachable, and committed to achieving the best outcome for me. Her expertise, attention to detail, and outstanding customer service gave me confidence throughout the entire journey. I'm extremely grateful for all her support, patience, and hard work. I would happily recommend Chloe to family, friends, and anyone looking for a reliable, knowledgeable, and professional mortgage advisor.

We honestly couldn’t recommend John highly enough. As first-time buyers, the whole mortgage process was completely new to us, but John made everything feel straightforward and stress-free from the very beginning. He was incredibly knowledgeable, responsive and reassuring, always keeping us updated and taking the time to answer all of our questions. We genuinely felt that he cared about getting the best outcome for us, and having someone we trusted guiding us through such a big decision made all the difference. We’re so grateful for all of John’s help and wouldn’t hesitate to recommend him to anyone looking for a mortgage adviser. Thank you, John, for making such an exciting milestone so much easier!

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.
