How to use this ANZ bank mortgage repayment calculator
If you're planning to buy a home or refinance an existing property loan, understanding repayments early can save you stress later. This calculator helps you estimate:
- Your regular repayment amount
- Total interest over the life of the loan
- Total amount repaid
- How much time and interest you can save by making extra repayments
Input fields explained
Loan amount: The amount borrowed from the bank, excluding your deposit.
Interest rate: The annual rate charged on the outstanding balance.
Loan term: The number of years you plan to repay the mortgage.
Repayment frequency: Weekly, fortnightly, or monthly repayment cycle.
Extra repayment: Any additional amount paid each cycle above the required minimum.
Example repayment scenario
Suppose you borrow $700,000 at 6.00% p.a. over 30 years. Your repayment amount will differ depending on whether you choose monthly or fortnightly repayments. If you also add a small extra repayment each period, you can often reduce total interest significantly and potentially repay the loan years earlier.
The reason is simple: extra money goes directly toward principal once interest is covered. A lower principal means less interest accrues in future periods.
Why repayment frequency matters
Monthly repayments
Most borrowers default to monthly repayments because they align with salary cycles and budgeting apps.
Fortnightly repayments
Fortnightly repayments are popular in Australia because there are 26 fortnights per year. This can improve cash-flow consistency and, depending on structure, may lead to faster principal reduction.
Weekly repayments
Weekly repayments can create an even faster debt reduction pattern for disciplined borrowers, though some people find the frequent schedule harder to track.
Strategies to reduce mortgage interest
- Round up repayments: Even small extra amounts can reduce total interest over decades.
- Use windfalls wisely: Tax refunds, bonuses, or inheritance can be directed into your loan.
- Review rates regularly: A lower rate can materially impact long-term cost.
- Avoid unnecessary redraws: Pulling money back out can extend payoff time.
- Stay consistent: Long-term discipline generally beats sporadic large repayments.
Important limitations of any mortgage calculator
This repayment calculator uses a standard amortisation model. Real home loans may include features and costs not captured here, such as:
- Application, settlement, or ongoing account fees
- Introductory rates and later variable rate movements
- Offset accounts that reduce daily interest calculation
- Fixed-rate break costs
- Lender-specific repayment policies
Always compare this estimate against the official figures from your lender before committing to a property purchase.
Final thoughts
A mortgage is usually the biggest financial commitment most households ever make. Running different scenarios now—changing rate, term, frequency, and extra repayments—can help you set a more realistic budget and avoid over-borrowing.
