Formula & methodology

Formula used

Regular repayment (principal & interest)

P = L × [r(1+r)^n] / [(1+r)^n − 1]

L is the loan amount, r is the periodic interest rate (annual rate ÷ number of periods per year), and n is the total number of repayment periods over the loan term.

LVR (Loan-to-Value Ratio)

LVR = loan amount / property value

Most owner-occupier lending requires an LVR of 80% or below (a 20% deposit); eligible first-home buyers can go to 95% LVR through Kāinga Ora's First Home Loan.

Variable definitions

Symbol	Meaning	Unit
L	Loan amount. property price minus deposit	NZD
r	Periodic interest rate. annual interest rate divided by repayments per year	%
n	Number of repayments. loan term in years × repayments per year	count

Step-by-step calculation

1. Calculate loan amount and LVR
Property price minus deposit gives the loan amount; LVR is the loan as a percentage of the property value.
2. Amortise the loan
Regular repayment is calculated from the loan amount, interest rate and term at your chosen frequency.
3. Check KiwiSaver withdrawal eligibility
After 3+ years of KiwiSaver contributions, most of the balance can be withdrawn for a first home (see the dedicated KiwiSaver first-home withdrawal calculator for the full rules).
4. Run the CCCFA affordability check
Compares the repayment plus other debts and expenses against income to flag likely affordability limits.

Limitations

The First Home Grant (a cash grant) was discontinued in Budget 2024 — this calculator does not include it. Only the KiwiSaver withdrawal and Kāinga Ora's First Home Loan remain.
Interest rates and LVR settings are entered by the user; actual bank offers depend on individual credit assessment and RBNZ's current LVR restrictions, which can change.
The CCCFA affordability check is a simplified approximation of a lender's actual serviceability test.

This page is educational. It applies a standard formula to the figures you enter and shows the arithmetic behind the result. It is an estimate, not an offer, a quotation or financial advice: real costs depend on the provider's pricing, fees and underwriting, and on circumstances this calculator does not collect.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What deposit do I need for a mortgage in New Zealand?

Tap to view the answer

Most owner-occupiers need a 20% deposit (80% LVR). Eligible first-home buyers can access as little as 5% through Kāinga Ora's First Home Loan, subject to income caps ($95,000 for a single buyer with no dependants, $150,000 for a buyer with dependants or a joint application).

Is the First Home Grant still available?

Tap to view the answer

No. The Kāinga Ora HomeStart Grant (up to $5,000 single, $10,000 couple) was abolished in Budget 2024, with applications closing 22 May 2024. It is not available in 2026. What remains is the KiwiSaver first-home withdrawal and Kāinga Ora's First Home Loan.

Can I use my KiwiSaver for a deposit?

Tap to view the answer

Yes — after 3 or more years of contributions, you can withdraw most of your KiwiSaver balance for a first home, leaving a small minimum balance. Only members who joined before 21 May 2015 have a non-withdrawable $1,000 kick-start amount.

What's the difference between fixed and floating mortgage rates?

Tap to view the answer

Fixed rates are locked for a set term (typically 1-5 years), giving repayment certainty. Floating rates can change with market conditions, offering more flexibility but more risk. Many NZ borrowers split their loan between both.

Does repayment frequency affect how much interest I pay?

Tap to view the answer

Yes — fortnightly repayments (26 a year) reduce interest faster than monthly (12 a year) because more repayments hit the principal sooner, and weekly repayments save slightly more again. The effect compounds over a 25-30 year term.

New Zealand Mortgage & Home Loan Guide (2026)

How mortgages work in New Zealand

A mortgage is a loan secured against a property. You repay the loan with interest over a set term (typically 25-30 years). Mortgages are the largest financial commitment most New Zealanders make.

2026 mortgage interest rates

For 2026, typical mortgage rates range from 5.5% to 7.5%. Fixed rates (1-5 years): 5.5-6.5%. Floating rates: 6.0-7.5%. Rates vary by bank, deposit size, and loan term. This calculator uses current market averages.

LVR – Loan-to-Value Ratio rules

Owner-occupiers typically need a 20% deposit (80% LVR). Eligible first-home buyers may qualify for a deposit as low as 5% (95% LVR) through Kāinga Ora's First Home Loan, subject to income caps. Investors generally face stricter deposit requirements set by individual lenders.

KiwiSaver for first home buyers

After 3+ years of contributions, you can withdraw most of your KiwiSaver balance for a first home. Only members who joined before 21 May 2015 have a $1,000 kick-start balance that can't be withdrawn — that payment was abolished for everyone who joined after that date.

The HomeStart Grant no longer exists

The Kāinga Ora HomeStart Grant (up to $5,000 single, $10,000 couple) was abolished in Budget 2024 — applications closed 22 May 2024. It is not available in 2026 and this calculator does not include it. What remains is Kāinga Ora's First Home Loan (a low-deposit loan, not a grant): income caps of $95,000 for a single buyer with no dependants, or $150,000 for a buyer with dependants or a joint application.

CCCFA and mortgage affordability

Under the Credit Contracts and Consumer Finance Act (CCCFA), lenders must assess your income, expenses, and debts to ensure you can afford the mortgage. This calculator helps you understand your borrowing capacity.

Fixed vs floating mortgage rates

Fixed rates: Set for 1-5 years. Offer stability and certainty. Floating rates: Can change with market conditions. Offer flexibility but more risk. Most NZ borrowers choose a mix of fixed and floating.

Principal & Interest vs Interest Only

Principal & Interest: You pay down the loan amount over time. Most common. Interest Only: You only pay interest for a set period (1-5 years). Lower repayments but the principal doesn't reduce. Usually for investment properties.

Repayment frequency impact

Fortnightly repayments (26/year) reduce interest faster than monthly (12/year). Weekly repayments (52/year) save even more. A $500,000 mortgage at 6% over 30 years saves ~$30,000 in interest with fortnightly vs monthly.

City property prices (2026)

Auckland median: ~$1,050,000. Wellington: ~$800,000. Christchurch: ~$600,000. Hamilton: ~$750,000. Regional NZ: $500,000-700,000. Prices vary significantly by location and property type.

First home buyer schemes that remain available

Kāinga Ora First Home Loan (5% deposit, income caps apply — this scheme was formerly called the Welcome Home Loan before Kāinga Ora's 2019 rebrand, it is the same live scheme under a new name), the KiwiSaver first-home withdrawal, and bank-specific first-home buyer packages. The separate cash First Home Grant has been discontinued and is not a current scheme.
