† This home loan calculator is intended as a guide only and is based on the Residential Owner Occupied rates. It is not intended to provide advice, and is not a quote or an offer of finance by BNZ.​ Low equity interest rate premium may apply to loans with less than 20% equity. An establishment fee of up to $150 may apply.

Classic home loans are no longer available for new applications from 19 September 2024.

Things you should know about our home loans and this calculator

All home loans are subject to our lending criteria (including minimum equity requirements), terms and fees. Some interest rates may require you to have a certain minimum equity in the property used as security, and for some rates a low equity interest rate premium rate may apply if you have a low loan to value ratio. An establishment fee of up to $150 may apply.

You can view the rates that apply to all home loans, including those whose interest rate type is Residential Owner Occupied or Residential Investor, on our compare page.

We’ve had to make some assumptions to calculate your approximate repayments:

  1. There are no changes to the loan amount and you don’t borrow any extra on this loan.
  2. You don’t make any additional lump sum repayments or increase your regular repayments above the standard repayments (but you could choose to do this to reduce the term and interest charges, if your loan allows).
  3. You make all your repayments in full and on time.
  4. The interest rate remains the same for the term of your home loan. Note that in reality, interest rates are likely to change over time.
  5. For monthly repayments, this calculator works out interest as if every month has the same number of days, even though some months have more days and others have fewer. For weekly and fortnightly repayments, interest is calculated daily. When you take out a loan with us, we use the daily method to calculate interest.
  6. Your repayment amounts are calculated on a “principal and interest” basis for the term of the loan.
  7. Actual amounts may vary slightly due to rounding.
