How to use the Australian Mortgage Calculator

Our free Australian mortgage calculator helps you estimate your home loan repayments based on your property value, deposit, loan term and interest rate. Simply enter your details using the sliders or type directly into the fields to see your weekly, fortnightly and monthly repayments update instantly.

The borrowing power estimate is calculated based on your annual income and monthly expenses, giving you a realistic guide to how much an Australian lender may approve. As a general rule, lenders assess that your mortgage repayments should not exceed 30% of your gross income.

Use the repayment visualisation charts to see how your loan balance reduces over time and how much of each year's repayments go toward interest versus principal.

Understanding your mortgage repayments

  • Weekly repayments — paying weekly can reduce total interest paid over the life of the loan
  • Fortnightly repayments — the most common repayment frequency in Australia
  • Comparison rate — includes fees and charges, giving a truer cost of the loan
  • LVR — Loan to Value Ratio, the percentage of the property value you are borrowing
  • LMI — Lenders Mortgage Insurance, required when LVR exceeds 80%
