Mortgage payment change calculator
With our calculator, you can compare two scenarios and consider the impact that different mortgage amounts, terms and interest rates may have on your monthly payments.
You can also compare your current rate with a new interest rate – for example, in the case of a change to the Bank of England base rate.
Unless you already have an interest only mortgage, you can’t switch to one.

What you need to know
About your interest rate
There is a limit to how low your interest rate can be if you're on a Nationwide tracker mortgage. Please check your mortgage offer for details.
About interest only mortgages
If you repay all or part of your mortgage on an interest only basis, your monthly payments only pay the interest due and don’t go towards reducing the amount you borrowed. So it’s important you have plans in place and regularly check they’re on track to repay the full amount by the end date of the mortgage.
