Mortgage Calculators

Our calculators are designed to help you get an understanding of what you can afford when looking for a new home and mortgage. Our three calculators can help you understand how much you can borrow, how much we will lend you and how much your repayments will be.


You can enter your monthly expenses into our handy calculator to see how much is left from your income at the end of each month. Remember to use your income after all taxes and national insurance is taken off. You should also think about what your mortgage may cost if the interest rate goes up.
