How much can I actually borrow?

The number your bank quotes you depends on whose servicing test you run. Each major NZ lender uses a different stress rate, different living-cost benchmarks, and different debt-handling rules.

How NZ banks decide

The four things that move your borrowing number.

The servicing test rate

Banks don't qualify you at your real rate. They test what you could pay if rates were 7.5% to 8%. That single decision moves your maximum borrow by $100k+.

Dependants and living costs

Each lender uses a different living-cost benchmark per dependant. ANZ and BNZ run higher assumed costs than ASB; that gap alone can shift your borrow by $50k.

Existing debt

A $400/month car loan eats about $50k of borrowing capacity. Banks treat existing debt as fixed expense at the test rate, not the real rate.

Deposit and LVR

Anything under 20% deposit is a high-LVR loan with extra hoops. Kāinga Ora First Home Loan lets you buy with 5% but income caps apply. KiwiSaver withdrawal counts toward deposit.

Common questions

Things people ask before they trust the number.

How much can I borrow on my income in NZ?

As a rough rule, 4 to 5 times your gross household income, less existing debt commitments, adjusted for living costs. The exact number depends on each bank's servicing test rate (currently 7.5% to 8% as of May 2026). A household on $120,000 combined income with no significant debt typically borrows in the $480k to $600k range, depending on lender.

Why does each bank give me a different borrowing number?

Each lender uses a different servicing test rate (the stress rate they assume your repayments would be at, even if your actual rate is lower) and different living-cost benchmarks. ANZ, BNZ, ASB, Westpac and Kiwibank all differ by a few percent. A broker can model against all of them at once.

Does this calculator give me a pre-approval?

No. This is a directional estimate. A real pre-approval requires application, full income verification, and lender-specific underwriting. Book a 15-minute call with Craig to start that conversation.

Does KiwiSaver count toward my deposit?

Yes. If you've been a KiwiSaver member for 3+ years and are buying a first home, you can withdraw most of your balance (leaving a minimum of $1,000) as part of your deposit. The Kāinga Ora First Home Grant adds up to $5,000 per buyer in some cases.

What about the Kāinga Ora First Home Loan?

The Kāinga Ora First Home Loan scheme lets eligible first-home buyers borrow with 5% deposit at the same rate as a 20% deposit loan. Income caps apply ($95,000 single, $150,000 couple/joint as of 2026, illustrative). House price caps vary by region.
