FAQs: Mortgage Calculators

Do you ever ask yourself, how much can I borrow for a mortgage? If so, using a mortgage calculator will give a clearer picture of this.

Essentially, a mortgage repayment calculator is there to help you calculate mortgage payments and affordability. This could be a standard residential mortgage, a Buy-to-Let, or even a remortgage.

Each calculator works differently; however, they all follow the same principle. You follow the specific calculator steps, filling out the information you’re asked for. Then, depending on the calculator, you will be given an outcome about the mortgage.

For example:

– An affordability calculator can act as a guide to how much you could borrow based on your income

– A Right-to-Buy calculator can give an indication of mortgage affordability for a Right-to-Buy scheme.

Calculation results should not be considered as a quote. Make sure you read the separate Key Facts Illustration (KFI) or European Standard Information Sheet (ESIS) before making a decision.

Our quick mortgage calculators can give you an indication of how much you could borrow depending on your circumstances.

Mortgage calculators can be an essential part of the planning process when looking to get a mortgage. No matter your circumstances, you’ll need to know how much you can borrow with your deposit. This goes for first-time buyers, landlords, foreign nationals, and anyone looking to remortgage.

This will allow you to budget both before you have got a mortgage and once you have obtained one. Using calculators can be a huge benefit to you throughout the process.

Mortgage calculators can give an indication of how much you could borrow based on your circumstances. However, because everyone’s situation is unique, mortgage calculators are not 100% accurate. That’s why it’s best to speak to a mortgage advisor to help you get the best deal.

As a Landlord with a large portfolio the number of products available are limited. Daniel was great identifying competitive products and we agreed to three buy to let mortgages which completed without any issues. All questions and responses were anwered in a timely and professional manner. I would recommend Daniel and Just Morgage Brokers.
