First home buyer calculator

Looking to get on the property ladder? Use this calculator to work out how much you may be able to borrow and compare different repayment scenarios. This calculator is aimed at first home buyers intending to live in the property.


*If you're a first home buyer, and you’re intending on living in the property, you'll usually need at least a 20% deposit. In limited circumstances you may be able to borrow with a 10% deposit but this is subject to loan-to-value ratio (LVR) restrictions.

This calculator is intended to provide general information only and is based on the details you provide. It doesn’t take into account your personal financial situation or goals. Therefore this isn’t financial advice, nor is it a quote or an offer of finance from Kiwibank Limited.

Please note the amount we can lend may differ from the results displayed. If you apply for a home loan, you’ll need to complete an application form, where you'll need to provide more detailed information. Without this information, this calculator uses assumptions and allowances to estimate the amount you may be able to borrow.

Estimated repayment assumptions

  • **The interest rate selected remains the same for the loan term. Realistically, the interest rate is likely to change over the loan term
  • You make all your repayments in full and on time
  • You pay the minimum required, and don't make any additional lump sum payments or borrow more under the loan
  • Your repayment amounts are calculated on a 'principal + interest basis' for the loan term.
