Adding money to your Cash ISA

When is interest paid into my savings account?

Interest for our cash savings accounts (including the Cash LISA and Cash ISA) is calculated on a daily basis and is paid into your account on the first day of the month.

When viewing your account under the Wealth tab, you can view how much interest you’ve earned in total, as well as today’s interest, which can be found underneath your balance. 💰

If you hold an Open Access Cash ISA, interest is calculated on a daily basis and is paid into your Cash ISA annually, on the anniversary of the date your ISA was first opened. You can see how much interest you’ve accrued in Wealth > Open Access Cash ISA > Breakdown.

Please note that all of our interest rates are annual equivalent rates (AER), meaning that the % rate indicates the equivalent amount of interest you would earn if the interest was paid as one lump sum annually, including compounding.
