How is interest calculated on a daily balance of £20,000?
Monthly earnings.

We calculate your interest daily, based on your end-of-day balance. We'll pay the interest to you on the first day of the following month.


This is the calculation we use:


(End-of-day balance x Gross interest rate) ÷ 365 days in the year = Interest earned that day.


The total amount of daily interest earned throughout the month is the interest earned for that month.
