Mortgage repayment calculator.
Estimate your monthly home loan repayment, total interest and total repaid for any loan amount, rate and term.
Repayment estimate
See the estimated monthly repayment on a loan amount.
Principal & interest, illustrative only. Enter any rate to test scenarios; it is not a quoted rate. Assumes the rate stays the same for the full term and excludes fees and charges. Actual repayments vary by lender and product.
Compare my optionsTest different scenarios
Change the loan amount, interest rate and term to see how each affects your repayment. A shorter term raises the monthly repayment but can save a large amount of interest overall.
The rate here is whatever you enter. It isn't a quote. We'll show you real options once we understand your situation.
What the numbers mean
The monthly repayment is the principal and interest payment needed to clear the loan over the term you choose. Total interest is what you'd pay the lender on top of the amount borrowed if the rate never changed. In practice, variable rates move, so treat the result as a guide.
Ways to reduce what you pay
- A sharper rate. Even a small rate difference adds up over 25 or 30 years. See the refinance savings calculator.
- Extra repayments. Paying a little more each month cuts both the interest and the term. Try the extra repayments calculator.
- An offset account. Savings held in offset reduce the balance you pay interest on. See offset vs redraw.
- Fortnightly repayments. Paying half the monthly amount every fortnight results in the equivalent of one extra monthly repayment each year.
Interest-only repayments
Interest-only loans have lower repayments during the interest-only period, but the balance doesn't fall and repayments rise when it ends. See interest-only loans, weighed honestly.
