About this tool

Australian lenders quote discounts, comparison rates and honeymoon periods, yet the repayment itself obeys one formula, which is what this calculator applies. Give it the purchase price, your deposit, the advertised rate and the loan term to see the monthly repayment, amount borrowed, total interest and total repaid. On the defaults, a 750,000 dollar purchase with a 150,000 dollar deposit borrows 600,000, and at 5.89 percent over 30 years the repayment is about 3,555 a month with roughly 680,000 in interest across the life of the loan. Results are plain AUD numbers and estimates only; your lender's figures and any fees will differ. Outputs are principal and interest estimates in AUD from your inputs; Australian fees, LMI and state charges are excluded. Verify with official sources. Not financial advice.Borrowing above 80 percent of the property value, an LVR over 80, usually triggers Lenders Mortgage Insurance, a one-off premium often capitalised into the loan; a smaller deposit can cost more in LMI than years of extra interest would. Offset accounts, redraw and extra repayments all reduce interest on variable loans. Stamp duty differs by state and territory. Verify with official revenue offices.
