Instant Access ISA (Issue 3)

What is the interest rate?

Your interest will be paid annually, on the 31st December.

We calculate the interest on the balance of your cash ISA at the end of each day.

Minimum investment Tax-free p.a. / AER %
£1+ 0.35%
£25,000+ 0.35%

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?

Interest rates are variable. This means we may change interest rates at any time if we reasonably believe that the change is needed.

See the ‘interest’ section of our terms and conditions for the full details.

What would the estimated balance be after 12 months with a £1,000 or £25,000 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.

Additional information

It’s important you understand how an ISA works, so take a look at our ISAs guide for more information.

Cash ISAs pay interest tax-free provided all terms and conditions of the account are met.

Tax treatment and rate of interest payable will depend on individual circumstances and may change in the future.

You can transfer your ISA with another provider to any of our on sale ISA products using this ISA Transfer Request form or this Stocks and Shares ISA Transfer Request form - depending on the current ISA you already have. This form will need to be completed in addition to the application form of your chosen ISA.
