To use our handy Interest Rate Calculator below, simply enter the principal amount, current interest rate as shown on the interest rates table, and the number of years before clicking the "Calculate" button to calculate the final amount.
When inserting figures, commas are not required. This is for illustrative purposes only and assumes that no additional deposits or withdrawals are made and the interest rate remains static over the chosen period. Interest has been capitalised to the account at the end of each complete year. Please note interest rates on variable rate accounts are subject to change at any time and account interest payment methods vary - please refer to individual account pages for details.
