Interest is calculated daily and charged on the last day of each month. To calculate the interest you will need to determine the outstanding balance of your loan account at the end of each day and note the number of days. Where a repayment has been applied during the month, do the same using the new balance. Take each balance and multiply by the annual interest rate, divide by 365, and multiply by the number of days.
