Mortgage & Loan Calculator

Calculate monthly payments, see how extra payments can save you money, and compare different loan scenarios to make informed decisions.

Loan Details

Loan Amount (NZD)

The total amount you want to borrow. For mortgages, this is typically the home price minus your deposit.

Interest Rate (% per year)

The annual interest rate offered by your lender. This greatly affects your monthly payment and total cost.

Loan Term (Years)

How long you'll take to pay off the loan. Longer terms mean lower monthly payments but more total interest paid.

Payment Frequency

How often you make payments. More frequent payments (weekly/fortnightly) can reduce total interest paid.

Extra Payment (Optional)

Additional amount you pay with each scheduled payment beyond the required amount. This dramatically reduces total interest and payoff time.

Even a 0.25% difference in interest rate can save thousands over the life of your loan. Compare offers from multiple lenders.

Making extra principal payments early in your loan can dramatically reduce total interest paid and shorten your loan term.

Remember to factor in insurance, rates, maintenance, and other homeownership costs beyond just your mortgage payment.

Apply for pre-approval before house hunting to understand your budget and strengthen your offers. Lock in rates when they're favorable.

Choose shorter loan terms or make bi-weekly payments to build equity faster. Consider refinancing if rates drop significantly.

Put down 20% or more to avoid private mortgage insurance (PMI). If you can't, plan to remove PMI once you reach 20% equity.
