How the Home Loan Calculator Works
This calculator uses the standard EMI (Equated Monthly Instalment) formula used by Australian lenders. It accounts for compound interest calculated on the outstanding principal balance each period.
The Formula
Where P = principal, r = periodic rate, n = total periods
Fortnightly vs Monthly
Choosing fortnightly repayments effectively means you make 26 half-monthly payments per year rather than 24. This extra principal reduction saves thousands in interest over the life of the loan.
Extra Repayments
Making additional repayments directly reduces your principal balance. Because interest is calculated on your remaining balance, a lower principal means less interest charged every period — accelerating how quickly you pay off the loan.
