Use the ANZ home loan calculator to estimate your mortgage repayments, compare rates, and plan your property purchase in New Zealand. Full guide with tips and FAQs.
Planning to buy a home in New Zealand? The ANZ home loan calculator is a free, practical way to estimate your repayments before you talk to a bank.
This guide explains how to use each input, what the results really mean, how ANZ’s loan types work, and the current lending rules that shape how much you can borrow. It’s general information, not financial advice.
The calculator is simple, but the value comes from understanding what each field represents — and being honest with your own numbers.
Loan amount is the purchase price minus your deposit. Buying at $750,000 with a $150,000 (20%) deposit means a $600,000 loan.
Loan term is how long you take to repay. Most NZ home loans run 25–30 years, and 30 years is ANZ’s maximum. A shorter term means higher repayments but far less interest overall.
Interest rate has to be typed in — the calculator doesn’t pull in live rates. Check ANZ’s current published rate, then enter it manually.
Repayment frequency can be weekly, fortnightly or monthly. Paying fortnightly rather than monthly effectively squeezes in one extra monthly payment a year, which trims both your term and your total interest.
After at least three years’ membership you can withdraw most of your balance towards a first home, but must leave at least $1,000 in your account. Any money transferred from an Australian super fund can’t be withdrawn for this.
If you can’t meet essential living costs, your provider (not Inland Revenue) may approve a limited withdrawal. Evidence is required and the bar is high.
A life-shortening condition or being permanently unable to work may allow a full withdrawal.
If you move overseas permanently (other than to Australia), you can generally withdraw after 12 months. Balances can instead be transferred to an Australian super scheme.
Your KiwiSaver balance forms part of your estate.
Early withdrawals permanently reduce your retirement savings. Rules and evidence requirements vary by scheme — check with your provider before applying.
Treat the output as a baseline, not a promise. Your real repayments depend on the rate ANZ actually offers you, your loan structure, and any fees. The Reserve Bank’s Official Cash Rate (OCR) is the main lever behind where home loan rates sit, so rates move over time.
ANZ is one of New Zealand’s big four banks, and picking the right structure matters as much as the repayment figure.
A fixed rate locks your interest rate for a set term — ANZ offers terms from around six months up to five years. You get certainty for budgeting, but if market rates fall you stay on your rate until the term ends, and repaying early during a fixed term can trigger break costs (ANZ calls these “Early Repayment Recovery”).
Useful to know: with ANZ you can lock in a fixed rate up to 60 days before your current fixed term ends.
A floating rate moves up and down with the market. It’s usually higher than fixed rates, but it’s flexible — you can make extra repayments or repay in full without break costs. Many borrowers split their loan, fixing part for certainty and floating part for flexibility.
This is where the original version of this guide was wrong, and it’s worth being clear. ANZ’s Flexible Home Loan is a revolving credit facility, not an offset account.
Revolving credit works like a large approved overdraft linked to your everyday account. Your pay goes in and reduces the balance you’re charged interest on; you can redraw up to your credit limit when you need to. Used with discipline it can reduce interest, but because the money stays available, it suits people who won’t simply spend the headroom. (A true “offset” loan — where separate savings are netted off your loan balance — is offered by some other banks, but that’s a different product.)
A standard ANZ home loan is a table loan: repayments stay level, but the split between interest and principal shifts over time. A reducing loan has higher early repayments that fall as the balance drops. Most NZ borrowers choose table loans for predictability.
Before you rely on a repayment figure, it helps to know the Reserve Bank rules that limit low-deposit and high-debt lending.
A loan-to-value ratio (LVR) compares your loan to the property’s value. A debt-to-income (DTI) ratio compares your total debt to your gross income. The Reserve Bank sets “speed limits” on how much high-LVR and high-DTI lending each bank can do.
If your deposit is under 20%, ANZ (like most lenders) may add a Low Equity Premium — an extra charge on higher-LVR lending. The calculator won’t add this automatically, so use a rate that reflects your deposit size when you run your numbers. For a broader view across lenders, our mortgages guide and general home loan calculator walkthrough are good next reads.
If you’re buying your first home, the raw repayment figure is only part of the picture — and one widely repeated claim is now out of date.
Estimates weekly, fortnightly or monthly repayments and the total interest over the loan’s life.
Gives a rough idea of how much you might borrow based on your income and expenses.
Shows how much interest and time you save by paying a bit more each week or a one-off lump sum.
Estimates the interest you could save by linking savings accounts to your loan.
Weighs rate certainty against the flexibility to make extra repayments.
Using several tools together gives a fuller picture than a single repayment estimate. All results are indicative — your real numbers depend on BNZ’s full assessment.
The key correction: the First Home Grant no longer exists — it was scrapped on 22 May 2024. What remains is the First Home Loan (buy with as little as a 5% deposit, underwritten by Kāinga Ora) and the KiwiSaver first-home withdrawal after three years’ membership. If KiwiSaver is part of your deposit plan, see our KiwiSaver guide for how withdrawals work.
For independent budgeting help, Sorted — the free service run by Te Ara Ahunga Ora Retirement Commission — has a mortgage calculator with rate stress-testing and a full amortisation schedule, which is a useful cross-check against ANZ’s tool.
Once the calculator has given you a comfortable range, pre-approval (also called conditional approval) is the next step. Broadly, ANZ will ask you to:
Pre-approval is usually valid for a set period (often around 90 days — check the current terms), and it doesn’t guarantee the final loan, since ANZ still needs to approve the specific property. It does, however, make your offers more credible to vendors.
The repayment figure isn’t fixed for life. Real strategies include making extra repayments (even small ones cut interest disproportionately), using a split structure, reviewing your rate at rollover instead of auto-refixing, and increasing your repayment frequency.
It’s also worth comparing lenders rather than defaulting to your existing bank. Running the same scenario at ANZ and a competitor — for example using our BNZ home loan calculator and BNZ mortgage calculator guides — can reveal a meaningful gap. A mortgage adviser can also access several lenders on your behalf; advisers in New Zealand must follow the Code of Professional Conduct and give priority to your interests, and are overseen by the Financial Markets Authority.
Use the ANZ calculator to set a realistic repayment range and stress-test it against higher rates. Then compare structures and lenders, confirm which fees and low-equity charges apply to your deposit, and consider talking to an adviser. Buying a home is likely your largest financial decision — the more grounded your numbers, the better your outcome.

| Type | How it works | Good to know |
|---|---|---|
| Fixed rate | Locks your rate for a set term, from 6 months to 5 years. | Certainty for budgeting. Exiting early can trigger an early repayment charge. BNZ allows up to 5% of the original loan a year in extra repayments without a break fee. |
| Classic (floating) | A variable rate that moves with the market. | Full flexibility to make extra repayments or repay in full without break fees; usually a higher rate than short fixed terms. |
| TotalMoney (offset) | Links your savings and everyday accounts so their balances offset your loan. | You only pay interest on the difference; repayments stay the same. Up to 10 accounts can be linked. |
| Rapid Repay (revolving credit) | A floating facility that works like a large approved overdraft on your transaction account. | Flexible, but suits disciplined borrowers who won’t simply spend the available headroom. |
A Low Equity Premium (an added interest charge) applies if your deposit is under 20% (an LVR above 80%). An establishment fee of up to $150 may apply. You can also hold a fixed rate for up to 60 days. Confirm current rates, fees and conditions with BNZ.
No. You have to enter the interest rate yourself. Check ANZ’s current published rate and type it in, and ideally run a second scenario at a rate about 2% higher to stress-test your budget.
No. The ANZ Flexible Home Loan is a revolving credit facility — it works like a large approved overdraft linked to your everyday account, where your income reduces the balance you’re charged interest on. It is not a savings-offset loan.
Low-deposit lending is limited by the Reserve Bank’s LVR speed limits, and ANZ may add a Low Equity Premium — an extra charge — on lending above 80% of the property’s value. Use a rate that reflects your deposit size when you run the calculator.
No. The First Home Grant was scrapped on 22 May 2024 and Kāinga Ora no longer accepts applications. First-home support that remains includes the Kāinga Ora First Home Loan (from a 5% deposit) and the KiwiSaver first-home withdrawal after three years’ membership.
Debt-to-income restrictions have applied since 1 July 2024. Banks can make only a limited share of new lending above a 6× DTI for owner-occupiers and 7× for investors, though new builds, refinancing and Kāinga Ora First Home Loans are generally exempt.
Repaying some or all of a fixed-rate loan early can trigger a break cost that ANZ calls “Early Repayment Recovery.” The amount depends on how rates have moved since you fixed, so ask ANZ for a written figure before you act.
No. Conditional (pre-)approval tells you the maximum ANZ is likely to lend, usually for a set period, but the bank still needs to approve the specific property you buy.
