Base rate calculator
If there is a change to the Bank of England Base Rate, then use this calculator to understand how your monthly payments could change.
See how your monthly payments could change
Use our calculator to get an idea of how much your monthly payments could change following a Bank of England Base Rate change.
Your standard simple interest rates track any movements in Base Rate, but not movements below 0% . Our calculator does not take compounding into account (this is when we charge interest on your balance, including on any interest we charged before), and is only intended to give an estimate of how your monthly payments could change. If Base Rate changes we will confirm your new rates and monthly payment on your statement.
We recommend you use your current balance which you can find by logging onto Online Services. If you’re not registered for Online Services, you can use the balance on the last credit card statement we issued to you.
Remember that some of your balance may be on promotional rates which are not affected by changes to the Bank of England Base Rate. You should be mindful of this and exclude these balances when using the calculator.
