How is interest calculated for the Cash ISA?

For our Cash ISA, interest is calculated daily and is paid into your account on the 1st of every month.

Interest is calculated based on the money you’ve contributed, interest paid, and interest due (interest that has been earned but not yet credited to your account).

In the Moneybox app, you can see how much interest you have earnt each day by viewing your “today’s interest” figure in the Wealth tab. You can also see how much interest you are due to receive for the current month in your account breakdown, accessible in Wealth > Tap on your account > Breakdown.

Additionally, you can find an example of how much interest you could earn for your account in the Summary Box found on our website, which can be accessed by selecting your chosen account under the ‘Savings’ heading, and scrolling down.

Please note that our advertised interest rates are annual equivalent rates (AER) and our rates are also variable, which means they could go up or down in future.
