This calculator assumes the interest rate does not change during the period of time selected and that no withdrawals are made. The calculations shown include the total amount of interest earned as part of your total savings and include compound interest. The tax treatment of your savings will depend on your individual circumstances and may change in the future.

What is the interest rate? Interest is payable on this account. The Wealthify Cash ISA interest rate is based on the Bank of England base rate. The interest rate is variable and tracks at a margin of 0.45% (gross) below the Bank of England base rate ("Tracking Rate"). The current interest rate is 3.35% AER / 3.30% tax-free p.a. (variable).

If you close your Cash ISA mid-month, ClearBank will calculate the interest up until the day before you close your account, before paying it into your account.
