Affordability calculator

See how much you could borrow with our fixed rate, discounted rate or family-assisted mortgages.

The mortgage will be secured on your home. Your home may be repossessed if you do not keep up repayments on your mortgage.

Whether you’re a first-time buyer or moving home, our quick and easy to use mortgage affordability calculator gives you a quick estimate of how much you might be able to borrow for your next home.

Taking into account your income, outgoings and how long you want to have the mortgage for, our calculator helps to give you a clearer idea of your mortgage borrowing potential.

This calculator is for illustrative purposes only. It is not a mortgage offer or guarantee of receiving a mortgage offer.

We have a separate calculator if you want to see how much you can borrow for a Buy to Let mortgage.
