Calculate your principal and interest repayments

Use our principal and interest loan calculator to estimate your weekly, fortnightly or monthly home loan repayments. Enter your loan amount, interest rate, loan term and preferred payment frequency to see how much you could repay and the estimated total interest over the life of the loan.

With a principal and interest home loan, each repayment covers the interest charged by the lender and repays part of the original amount borrowed—the principal. As the outstanding balance decreases, more of each repayment will generally go towards reducing the principal.

You can adjust the figures in the calculator to compare different loan amounts, interest rates and terms. A shorter loan term will usually result in higher regular repayments but less interest paid overall. A longer term may reduce the regular repayment amount but generally increases the total interest paid.
