I have been working with James since purchasing our home in 2018, and I cannot recommend him highly enough. Over the years, James has consistently provided clear, honest, and well-informed mortgage advice. Whether we have been remortgaging, reviewing our options, or discussing financial protection, he always takes the time to explain everything thoroughly and ensure we understand the available choices. What I particularly value is that James is proactive in highlighting important information and considerations that we may not have thought about ourselves. His advice is always tailored to our circumstances, and I have complete confidence in the recommendations he provides. The remortgage process can often feel overwhelming, but James makes it straightforward and stress-free. His professionalism, responsiveness, and attention to detail are second to none, which is why I continue to return to him whenever we need mortgage advice. Thank you, James, for your continued support and excellent service over the years. I would happily recommend both James and Mortgage Advice Bureau to anyone looking for reliable and trustworthy mortgage advic

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.
