Use this calculator to estimate your home loan repayments, total interest, and how much time you can save with extra repayments.

How to use this ANZ bank mortgage calculator
If you are comparing home loans, the first number you should understand is your expected repayment. This ANZ-style mortgage calculator helps you quickly estimate what your budget might look like before talking to a lender or broker.
Enter your expected loan amount, annual interest rate, loan term, and repayment frequency. You can also add an extra repayment amount to see how much faster you could pay off your mortgage and how much interest you may save over time.
What this calculator shows
- Minimum repayment: The estimated amount needed each period to repay principal and interest over your chosen term.
- Repayment with extra: Your minimum repayment plus any optional additional amount.
- Total interest: Estimated interest paid over the life of the loan.
- Loan payoff time: How long it may take to become mortgage-free.
- Interest savings: How much extra repayments can reduce your total interest.
Mortgage repayment formula (simple version)
Most principal-and-interest home loan calculators use a standard amortisation formula. In plain terms, the repayment is based on:
- Loan balance
- Interest rate per period
- Total number of repayment periods
Because interest is charged on the remaining balance each period, earlier payments usually contain more interest, while later payments include more principal.
Example repayment scenario
Sample numbers
- Loan amount: $650,000
- Interest rate: 6.19% p.a.
- Term: 30 years
- Frequency: Monthly
With values like these, your repayment will typically be several thousand dollars per month. If you add even a small extra amount (for example, $100 to $300 each month), you may reduce both your payoff time and total interest by a meaningful amount over the full loan term.
Factors that can change your results
1) Interest rate changes
Variable rates can move with market conditions. A small increase in rate can have a large long-term impact on total interest paid. Run multiple scenarios to stress-test your budget.
2) Loan term length
A longer loan term lowers your regular repayment but increases total interest. A shorter term increases repayments but may reduce total borrowing cost.
3) Repayment frequency
Weekly or fortnightly repayments can help some borrowers stay disciplined. In many cases, increasing effective payment frequency can reduce interest over time, especially if the annual amount paid is higher.
4) Extra repayments
Extra repayments usually go directly toward principal, lowering the amount interest is calculated on in future periods. This is one of the most powerful ways to reduce the cost of a mortgage.
5) Fees and loan features
This calculator focuses on principal and interest estimates. Real loans may include application fees, package fees, redraw restrictions, offset account features, and discharge costs.
Using this tool when comparing ANZ home loans
When evaluating options, use the calculator with at least three scenarios:
- Base case: Current rate, no extra repayments
- Rate rise case: Add 1.00% to test affordability
- Accelerated payoff case: Add regular extra repayments
This approach gives you a practical view of both risk and opportunity. It also helps you prepare better questions before speaking with a bank representative.
