Mortgage Repayment Calculator
Calculate the cost of mortgage repayments. See how different interest rates, loan terms and more can affect a home loan’s cost.
How does this work?
- Enter the amount you want to borrow.
- Select the loan term from the slider.
- Add the interest rate for your loan. We have added the default interest rate, which is today’s average Big 4 owner occupier advertised discounted variable rate (LVR 80%).
- Select the repayment type. This is whether you’d be paying back the principal and interest or just the interest (for a certain number of years).
- The results are calculated automatically. Select if you’d like to see estimated weekly, fortnightly or monthly values.
- What you can also do:
- Email the results to yourself for future reference.
- Check over the repayments graph to see what the total repayment values are over the period.
- Go through the full repayment schedule. You can download the file easily on your device.
- Click or tap ‘Reset’ to start over.
- Browse available loan options right below the calculator.
- To see more loan options, click or tap on the Compare home loans button.

- All calculations are estimates only; they are not guarantees, pre-qualifications or pre-approvals for borrowing. All results are based solely upon the data entered into the calculator.
- It is assumed that data entered into the calculator, including interest rates, do not change for the lifetime of the loan - unless specified.
- The Present Value provided by this calculator is displayed as the amount labelled 'Loan amount'.
- At the end of the interest-only period, the rate may change. For this calculation, rate switches to the current rate.
- The current rate is today’s average big 4 owner occupier advertised discounted variable rate (LVR 80%), unless you have inserted your own rate.
- Interest is calculated by compounding on the same frequency as the repayment selected, i.e. weekly, fortnightly or monthly.
- Months are assumed to be of equal length. However, given some months are longer than others, interest charged may vary depending upon the month.
- One year is assumed to contain exactly 52 weeks or 26 fortnights. Thus each year has 364 days.
- The calculator uses the unrounded repayment to derive the home loan summary line graph and repayment schedule. However, institutions may round repayments to the nearest cent.
- Your final mortgage repayments or borrowing amount will depend on your lender’s eligibility criteria among other factors.
- Calculator does not include the cost of fees or other extra charges.
- Calculator does not account for changes to interest rates over time.
- This calculator is for information purposes only. Any advice is general and has not taken into account your personal circumstances. Consider whether you need financial advice from a qualified adviser.
- After the interest only term ends, your repayments will change based on the current* interest rate. This rate is subject to change. Read our full disclaimer.
