Deposit and Interest Frequency
Compound interest is calculated on the starting balance and factors in regular monthly deposits. It assumes no withdrawals, additional deposits or changes in interest rates occur during the saving period.
Each calculation starts on the first day of the current month and assumes all deposits are made on the first day of the month. Interest is calculated daily and compounded monthly.
Fees & charges
This calculator does not take into account the impact of fees and charges or tax on interest earned that may impact the amount you could save.
Number of Weeks & Fortnights in a Year
The outputs are based on a 364 day year; one year is assumed to contain exactly 52 weeks or 26 fortnights. All months and fortnights are assumed to be equal. Given some months are longer than others interest charged will vary depending upon the month.
Rounding
The amounts shown are rounded to the nearest dollar.
