Summary
This calculator estimates the monthly principal-and-interest repayment on a New Zealand home loan. It splits the first payment into interest and principal, then builds a yearly amortization summary showing the balance paid down over the full loan term. It covers payment math only, not lending criteria, LVR restrictions, or tax advice.
How it works
- Enter the loan amount in New Zealand dollars.
- Enter the annual interest rate as a percentage.
- Enter the loan term in years.
- Read the monthly repayment and the interest-versus-principal split in the results panel.
- Scroll the yearly amortization summary to see the balance decline over the loan term.
Use cases

- Checking how a higher interest rate changes the monthly repayment.
- Comparing loan terms, such as 25 years versus 30 years.
- Seeing how much of each early repayment goes toward interest versus principal.
- Estimating the remaining loan balance at a given year of the term.
