Members' 2 Year Fixed Rate ISA (Issue 71)
What is the interest rate?
Your interest will be paid annually, on the 31st December and at maturity.
We calculate the interest on the balance of your cash ISA 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 funds.
Can The Cambridge change the interest rate?
The interest rate is fixed until the maturity date, meaning it won’t go up or down during the fixed term. Your account will mature two years from the date of your initial deposit.
What would the estimated balance be after 24 months with £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.
