Calculator Assumptions

Expense Details and Default Values

a) Default core expense annual allowance - borrower assumed to have core level of annual expense, depending on whether single or joint and the number of dependants, currently as below:

Number of dependants	Single	Joint
0	$11,400	$14,400
1	$14,280	$17,280
2	$17,160	$20,160
3	$20,040	$23,040
4	$22,920	$25,920

b) Default extra core expenses for more than 4 dependants - currently set at zero.

c) Maximum percentage of income available - percentage of income available for paying expenses and servicing proposed borrowing, default currently set at 85%.

Loan Details

a) Interest rate increase allowance buffer - calculator has capability to assume a higher interest rate than rate entered by user when determining maximum amount that can be borrowed. This allows for affordability of possible rate increases under the loan. Current version of the calculator uses an interest rate buffer of 1.5%.

b) Rounding rules for amount of loan - the calculator has the ability to round the maximum loan amount. The default is usually the current setting of the lower $1,000. Note that the amount of loan is calculated using the interest rate entered, plus any interest rate buffer, and then the resulting loan amount is rounded as required.

c) Interest rate for loan repayment - monthly repayment is calculated in respect of the rounded loan amount and using interest rate entered, not including any interest rate buffer.

Length of Month

All months are assumed to be of equal length. In reality, many loans accrue on a daily basis leading to a varying number of days' interest dependent on the number of days in the particular month.

Number of Weeks & Fortnights in a Year

One year is assumed to contain exactly 52 weeks or 26 fortnights. This implicitly assumes that a year has 364 days rather than the actual 365 or 366.

Rounding of Amount of Each Repayment

In practice, repayments are rounded to at least the nearer cent. However the calculator uses the unrounded repayment to derive the amount of interest payable at points along the graph and in total over the full term of the loan. This assumption allows for a smooth graph and equal repayment amounts.
