About our mortgage calculators
Our mortgage calculators are digital tools to help you estimate your mortgage affordability, remortgage payments, Stamp Duty fee, and more numbers when you’re moving or remortgaging. They’re a quick way to see instant financial figures before you talk to a mortgage broker.
Our mortgage calculators are designed to be easy to use and give you instant answers. With just a few details (sometimes that looks like your deposit amount, income, property price, etc) our calculators generate figures to give you an indication of what the potential costs could be.
While our calculators were built with the modern market in mind, please note that the mortgage market is always changing. Lenders will look at other factors, such as credit score, financial history, and personal costs. All of this information may impact the mortgage deal you’re able to get.
A mortgage is calculated based on the amount you borrow, the term of your mortgage, the type of mortgage you’ve chosen, and the interest rate.
There are two parts to a mortgage: the amount you borrow (the capital) and the interest charged on your loan. If you have a repayment mortgage, your monthly repayments will start to pay off both of these parts. An interest-only mortgage only pays off the interest of the mortgage payments, so the amount you borrowed (the capital) doesn’t go down.
If you’d like to talk it through a mortgage expert, we’re here to help. It’s easy and free to book in a call to go through your options and see the latest deals that are on offer to you.
