Home loan repayment calculator
Type your figures. Everything recalculates instantly.
The result is a calculation on your figures. It is not a guaranteed saving or an offer.
Worked out for the frequency you chose, at the rate you entered, over the term you entered.
Half or a quarter of the monthly repayment
A year has 26 fortnights and 52 weeks, so these amounts add up to a little more than 12 monthly repayments. The extra goes off the balance. Your lender decides which frequencies and amounts it accepts.
During interest-only years the balance does not fall, so the principal and interest repayment afterwards is higher than it would have been from the start.
With your offset balance and extra repayments
Your offset balance is as large as the balance owing, so in this calculation no interest is charged and every repayment goes off the loan.
Assumes the offset balance stays the same for the whole term and the extra amount is paid every period. Your loan contract sets how an offset account and extra repayments work, including any limits or fees.
The loan as a share of the property value you entered. A lender works this out with its own valuation.
If the rate were different
The steps are a quarter and half a percentage point either way around the rate you entered. They are scenarios, not forecasts.

This calculation is not a loan offer or a personal recommendation about a home loan.
Basis: the figures you entered and interest worked out per repayment period. The rate and costs you can actually get may differ.
- The rate you enter stays the same for the whole term.
- Interest is worked out per repayment: the yearly rate divided by 12, 26 or 52. Your lender's method can differ, so its figures can differ slightly.
- Repayments are made in full and on time. Fees, redraw and changes to the offset balance are not included.
- An offset balance lowers the balance that interest is worked out on. The repayment stays the same, so more of it goes off the loan.
- Transfer (stamp) duty and other purchase costs are not part of the calculation.

How the repayment is worked out
The calculator divides your yearly rate by the number of repayments in a year and applies the standard formula for a loan repaid in equal amounts over the term you enter. Weekly and fortnightly repayments are worked out on their own basis, which is why they are not simply the monthly figure divided.
For an interest-only start, each repayment covers only the interest for the years you choose. Principal and interest repayments are then worked out on the full balance over the years that are left.
With an offset balance or extra repayments, the calculator follows the loan repayment by repayment: interest on the balance less the offset, then the repayment and any extra off the balance, until nothing is owed.
