About this tool

Plan your New Zealand home loan repayments. Compare weekly, fortnightly, and monthly repayment schedules, calculate total interest payable over the loan term, and explore the savings of accelerated repayments.

How to use it

  1. 1 Enter the property purchase price and your cash deposit.
  2. 2 Set the annual interest rate and loan term in years (e.g. 25 or 30 years).
  3. 3 Select repayment frequency: weekly, fortnightly, or monthly.
  4. 4 Review payment amounts, principal balance, and total interest payable.

Questions

Why do fortnightly repayments save interest in New Zealand?

Paying half the monthly payment every two weeks results in 26 half-payments (equal to 13 full monthly payments per year), paying off the loan years earlier.

What is a typical deposit requirement for a home loan in NZ?

Most NZ banks typically require a 20% deposit for owner-occupiers, though first-home buyers may qualify with 5% to 10% under certain lending schemes.
