Double Access ISA
What is the interest rate?
Your interest will be paid annually, on the 31st December.
We calculate the interest on the balance of your account at the end of each day.
You earn interest from the day your funds are paid into your account, until the day before you withdraw your funds.
Can The Cambridge change the interest rate?
Yes, the Double Access ISA has a variable rate of interest which can go up or down. We may change interest rates at any time if we reasonably believe that the change is needed.
See the ‘interest’ section of Terms and Conditions for full details.
What would the estimated balance be after 12 months with a £1,000 deposit?
The following projection assumes the account is opened on 1st January and no further deposits or withdrawals are made. Projections are for illustrative purposes only and do not take into account individual circumstances.
