Interest rates are banded. This means that you’ll earn the higher rate on the first £10,000 of your balance and the lower rate on the additional balance over £10,000.
For example, if you had a balance of £10,100 interest would be calculated at the higher rate on the first £10,000 of your balance and the lower rate on the additional £100.
What would the estimated balance be after 12 months, based on a £1,000 deposit and a deposit for each band of interest?

The estimated value is based on no change to the interest rate during 12 months and no withdrawals made
Can Barclays change the interest rate?
Yes, rates are variable. We can increase or decrease the interest rates for the reasons set out in our ‘Barclays and you’ booklet, which is available in branch, or you can read our Terms and conditions for Personal customers. Both also explain when we may change the interest rates, and the notice we’ll give you.
