Savings plan calculator terms and conditions

The savings plan calculator provides the total balance of a regular savings plan, considering the opening balance, regular deposits, length of saving and interest rate that you input.

Calculator Assumptions

Length of Month:

All months are of equal length – 30 days.

Number of Weeks/Fortnights in a Year:

One year is assumed to contain exactly 52 weeks or 26 fortnights. This means each year has 364 days.

Timing of Interest Charges:

The calculator assumes that interest is charged to the loan account at the same frequency as the repayments are made. In practice, there may be differences between the timing of the loan repayments and the timing of the interest charges being added to the loan balance.

The calculator assumes that interest is calculated daily and paid monthly.


The total interest earned amount is rounded up to the nearest dollar.
