How we calculate interest

Interest can be charged on a daily basis and calculated either once a year, known as Annual Rest, or every day, known as Daily Interest. If you were to take out a new mortgage with us today it would automatically be on a daily interest basis, as all our new mortgages are calculated in this way.

Daily Interest

Your interest is calculated on the outstanding balance each day, so as your mortgage balance falls, the amount of interest charged falls immediately. However, if your mortgage balance increases, for example, if you missed a monthly payment, the amount of interest charged will increase immediately.

£advance amount multiplied by your % interest rate divided by 365 days


Or if you completed part way through the year:


£advance amount multiplied by your % interest rate divided by 365 days, then multiplied by the remaining days of the year

Annual Rest Interest

Interest on your mortgage is calculated and charged on a daily basis and is based on the previous years balance eg interest for 'year 2' has been based on the balance owing at 31st December 'year 1'. Interest accrues to your mortgage at a daily rate, we divide your annual interest by 365 and the amount charged depends on the interest rate prevailing on each day of the year. The table below may help to explain this.

£advance amount multiplied by your % interest rate

Your monthly repayments cover the annual interest, and if you have a repayment mortgage they will also repay part of the actual loan.
