See how switching from monthly to fortnightly repayments could save you money. Use our Fortnightly Repayment Calculator to compare schedules and reduce your mortgage faster.
Calculator results are estimates only and not quotes. Actual quotes will be provided by licensed brokers after you submit an enquiry.

Our Fortnightly Repayment Calculator helps you compare monthly vs fortnightly home loan repayments, so you can estimate whether paying more frequently could reduce interest and shorten your mortgage term. Many borrowers choose fortnightly repayments to align with pay cycles and to potentially repay principal sooner, which can lower interest over time.
This calculator is a general information tool only. It provides estimates and does not consider your objectives, financial situation or needs. Results are not a quote, and your lender’s actual repayment method, fees, and interest calculation (often daily interest charged monthly) can produce different outcomes. If you’re unsure, consider speaking with a licensed mortgage broker or adviser before changing repayment frequency.
How to complete the form (in order) for the most accurate estimate:
1. Loan Amount (in dollars). Enter your current loan balance or the amount you plan to borrow. Use the loan principal only (exclude ongoing fees unless they are capitalised into the loan). Round to the nearest dollar for a cleaner comparison.
2. Term of Loan (in years). Select the total remaining term (for an existing loan) or your intended term (for a new loan). A longer term usually reduces each repayment but increases total interest paid.
3. Interest Rate (percent per annum). Choose the interest rate you expect to apply. If you have a variable rate, you can re-run the calculator with higher and lower rates to stress-test your budget.
4. Calculate. Review the comparison between monthly repayments and fortnightly repayments (often shown as half the monthly amount paid every two weeks).
How to interpret the results: focus on the estimated repayment amount per frequency, the total interest over the life of the loan, and any reduction in the time to repay. If the fortnightly method results in 26 payments per year, you may effectively make the equivalent of one extra monthly repayment each year, which can accelerate principal reduction. Confirm with your lender how fortnightly repayments are applied and whether extra repayments are allowed without fees.
