The figures and formulae used within this Calculator may change at any time without notice. The calculations are intended as a guide only. When assessing ability to service a loan, the Bank may use an interest rate that is higher than the current interest rate for the loan requested. We call this the Assessment Interest Rate. Changes in economic conditions may see variations in rates requiring higher repayments during the life of a loan and it can be of assistance, when setting budgets, to consider such events.
