Home Loan Repayment Calculator
See what a home loan would cost to repay — per month, fortnight or week — along with the total interest over the term and how much faster extra repayments clear it. It’s arithmetic on the figures you enter, not advice on what you can borrow.
Monthly repayment
$3,694.30
- Total interest over 30 years
- $729,949
- Total repaid (loan + interest)
- $1,329,949
Indicative only — general information, not credit assistance or advice. It assumes a fixed rate for the whole term and doesn’t include fees, offset or redraw. Your lender’s actual repayment will differ. Compare a mortgage broker to find the rate you’d actually be offered.
How it works
For a principal-and-interest loan, this uses the standard amortisation formula: each repayment covers the interest charged that period, and whatever’s left chips away at the balance. Early on most of your repayment is interest; later, most is principal. Change the rate or term and you can see how sharply the total interest moves.
A word on the “pay fortnightly and save years” claim. That popular tip only works because people pay half the monthly amount every fortnight — which is 26 half-payments, or 13 monthly payments a year instead of 12. The saving comes from paying more, not from the frequency itself. Switching to fortnightly at the mathematically equal amount barely changes anything. To see the real effect, use the extra-repayment field — that’s where the years come off.
We keep it deliberately simple and honest: it assumes a fixed rate for the whole term and leaves out fees, offset and redraw, because those vary by lender and product. And it will never tell you what you can borrow — that’s credit assistance, which needs a licence we don’t hold. For the rate you’d actually be offered, and how a broker is paid, compare a mortgage broker or read how broker commission works.
