Understanding interest

Want to see how a change to your balance or interest rates could affect you? You're in the right place.

Please keep in mind that our calculator is just a guide, and it doesn't take into account all the things that affect your payments. It gives you an idea of what changes to your account could mean to your monthly minimum payments and interest.

A few things to remember

The calculator can help you plan ahead, but bear in mind it's only a guide. It gives you an idea of the effect that Bank of England Base Rate changes might have on your monthly minimum payment and the interest you pay.It doesn't take into account everything that may affect you. For example - the calculator uses a single interest rate, but your standard and cash interest rates may be different.

It also doesn't allow for any promotional interest rates or Purchase Plan balances that you might have. (Remember, your promotional and Purchase Plan balances aren't affected by changes to the Base Rate).

How your minimum payment is calculated

The final calculation you can see is based on the whole balance across an average number of days in a month. It assumes that you're making your monthly minimum payments and there are no fees or arrears.

If you opened your account after December 2010 or selected "Don't know", the calculator assumes that your minimum payment will be the greatest of:

  • £5 (or the total outstanding balance if it's less than £5)
  • 2.25% of your main balance plus any purchase plan instalments due for that month (if you have a plan)
  • Default charges and annual fees, plus interest, plus 1% of your main balance

If you opened your account before December 2010, the calculator assumes that your minimum payment will be the greatest of:

  • £5 (or the total outstanding balance it it's less than £5)
  • 2.25% of your main balance
  • 0.1% of your balance, plus interest

These calculations assume that standard terms and conditions apply.
