On Demand variable rate for all deposits: 0.05%.
An On Demand interest rate applies during the 6-business day Variation Period following the maturity of a Term Deposit, if no instructions for renewal or account closure have been received. The rate is applied from maturity up to the day when instructions are received; and after 6 days without instructions the deposit will be reinvested for the same term as previously, but at the fixed interest rate in place at the time.

Term Deposit Calculator
This calculator should be used as a guide only and shouldn't be relied on for making a decision in relation to renew or open a term deposit as you should consider whether the product features suit your needs. The interest calculations on this calculator are not saving recommendations but are monthly estimates only of how much could be saved based on the information provided. This calculator doesn't take into account the impact of fees and charges, tax on interest earned, changes to interest rate or closing your account before the end of term. Calculations don't take into account all of your relevant personal circumstances and you should consider whether a term deposit is appropriate for you. If you need assistance, obtain advice from a banker or financial adviser.
How this calculator works
This is a simple interest calculator. Results vary from the actual interest earned on Westpac products due to differences in the calculation methods used.
Calculator assumptions and method
Each calculation starts on the first day of the current month and assumes the initial deposit is made on the first day of the month and assumes the account is not closed before maturity. Interest is calculated daily. The calculator allows interest payment at maturity. Total amounts (including interest earned) are rounded to the nearest cent.
