Product Summary
Cash ISA
2.75% Gross / 2.78% AER* variable
Interest accrues daily, based on the balance of your account and will be paid by Griffin monthly on the first of each month into your Cash ISA account and compounded.
If you close your account at any point in the month, interest accrued up until that point will be paid immediately and no further interest will be accrued.
Yes, the interest rate can change at any time.
The rate tracks the Bank of England base rate. If the base rate changes, the new interest rate on your account will apply within 24 hours.
If Prosper changes the rate to your disadvantage, you will be given 14 days’ notice before the change comes into effect.
At current interest rates:
A deposit of £1,000.00 would earn £27.80 after 12 months, for a final balance of £1,027.80
A deposit of £5,000.00 would earn £139.00 after 12 months, for a final balance of £5,139.00
These are illustrative examples and are not based on your individual circumstances, such as the exact number of days in any given period (which may vary).
Interest is calculated using the Gross Rate. The AER (Annual Equivalent Rate) reflects the cash amount that would be paid if deposited at the Gross Rate for a one year period, capturing any positive effects of compounding interest.
This account is available to UK residents over the age of 18, with a minimum balance of £1.00. There is no maximum limit on the amount that may be held in a Prosper Cash ISA, however you may only deposit the maximum ISA allowance each year. Currently the maximum annual ISA allowance is £20,000.
You can open, view and manage your account directly through Prosper.
Yes, withdrawal requests can be made through Prosper at any time after opening the account, and in any amount. The Prosper Cash ISA is flexible so you can withdraw money and put it back within the same tax year without using more of your ISA allowance.
