Mortgage Calculator FAQs
Home loan instalments, also called mortgage repayments, are based on the loan amount outstanding, the loan term (in years) the frequency of mortgage repayments (monthly, fortnightly or weekly), the interest rate, fees and whether the home loan is a ‘principal and interest' loan or an ‘interest-only' loan.
The total amount you will repay on a mortgage is based on the original mortgage amount, the interest rate plus fees and charges and the loan term (the length of the home loan in years).
The quicker you pay off your home loan the less interest you will pay to the lender. If you can afford to make extra repayments, less interest will be charged over time and the term of the loan will be cut as well. Even moving from monthly to more frequent repayments can cut your overall interest bill and repayments significantly. You can calculate how quickly you might be able to pay off your home loan by adjusting the level of repayments in our mortgage calculator.
*Important Information to Note
The Mortgage Calculator calculates the type of repayment required, at the frequency requested, in respect of the home loan parameters entered, namely amount, term and interest rate.
Length of Month
All months are assumed to be of equal length. In reality, many home 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, mortgage repayments are rounded to at least the nearer cent. However the mortgage 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 home loan. This assumption allows for a smooth graph and equal mortgage repayment amounts.
