I’ve been getting my mortgages from David at MAB for 6 years now. He always gives sound advice on the market leading products that are available, and are suitable for my financial situation. Excellent communication, is always available on the phone or email to discuss any issues or just general information. I have recommended him to family and friends, in which a lot of them now only use David to get them the absolute best deal possible for them. I would only use David to get my mortgage and cannot recommend him enough.

I just wanted to say a huge thank you to Pip and Emma for everything he did for us. As first-time buyers with poor credit and very little knowledge about the whole process, we honestly felt quite clueless and overwhelmed at the start. But Pip was absolutely amazing from beginning to end. He was so kind, understanding and completely non-judgemental, which made such a difference to us. He took the time to explain everything clearly and made sure we understood every step. His knowledge and advice were incredible, and he managed to find us the best deal possible. We’re also so grateful for how quickly everything was handled — it all moved along so smoothly and was completed in such a rapid time. We genuinely couldn’t have done it without you. Thank you again for all your help, support and patience. We’ll always be grateful for everything you did for us.

When my husband became terminally ill, our lives became extremely stressful for many reasons. A crucial factor was the monthly cost of our mortgage and we decided to take action. Due to my husband's poor health, I carried out all my research on my own, not easy! I was impressed with everything I read about the Mortgage Advice Bureau and gave them a call. Because of the uncertainty of our situation, I thought perhaps I'd be advised to wait before applying for the product I had in mind. Instead, my advisor, Jonathon Cannings, was incredibly sympathetic and gave me the confidence to continue. Phone calls, texts and emails gave us the scope to discuss many details, and finally, it all fell into place and a few months later I have a new affordable mortgage and the financial stress , at least, has gone. Thanks to the brilliant support and help of MAB, I can now concentrate on caring for my husband without worrying about monthly outgoings! I'd recommend them wholeheartedly.

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.
