Base Rate Calculator

If the Bank of England decides to change the Base Rate this could affect the interest you pay on your credit card.

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 Internet Banking. If you’re not registered for Internet Banking 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. You may contact customer services on 0345 964 5645 (8am – 8pm, seven days a week) to obtain more information. Not all Telephone Banking services are available 24 hours a day, seven days a week.
