This calculator gives estimates for general information only. It is not credit advice or an offer of credit, and it does not take into account your objectives, financial situation or needs. Results depend on the figures you enter and the assumptions shown below, which you can edit. Actual amounts will vary with lender fees, charges and credit criteria. Consider your circumstances and seek advice before acting. Talk to us and we'll search for options available to you across 60+ lenders.
The default values are examples only and are not a quote, an offer of credit or a suggestion about any particular loan or lender. Results are not intended to be relied on when making a decision about a financial or credit product. Consider obtaining advice from a licensed professional before making financial decisions.
Assumptions (you can change these)
Every figure this calculator uses is one of the inputs above, so you can change all of them, including the example interest rate, to match your own situation. The conventions below describe how the maths works.
Displayed repayments use the standard Australian lender convention: the monthly amount is calculated from the monthly rate (annual rate divided by 12) over the term in months, then weekly is monthly x 12 / 52 and fortnightly is monthly x 12 / 26. Because 26 fortnightly or 52 weekly payments run slightly ahead of 12 monthly payments, paying at the convention amount clears the loan a little before the nominal term, which is why the "paid off in" figure can be shorter than the term you set.
Interest-only payments are the annual interest divided across the payments in the year. After an interest-only period, the principal and interest payment is recalculated on the remaining balance over the remaining term.
Interest accrues once per payment period at the annual rate divided by the number of payments per year. Daily interest accrual and rate changes over time are not modelled, and a zero rate repays in equal instalments.
All amounts are rounded to the cent each period, and the final payment is adjusted so the balance lands exactly on zero.
No fees or charges are included: application fees, ongoing fees, valuation fees and lender's mortgage insurance are not modelled and would increase the true cost of the loan.
