Carfinance.org.nz exists because researching a car loan in New Zealand usually means handing over a phone number before getting a straight number back.
We've flipped that. The calculator runs in the browser, the inputs stay on-device, and a lender only gets contacted if the user chooses to. If the number works for the household budget, one click hands off to our vetted partner for a formal quote. If it doesn't, closing the tab is fine and nobody gets chased.
Why we built it
An hour spent typing "car loan calculator NZ" into Google reveals a pattern. The first few sites want a full name, a date of birth, and two contact methods before they show any numbers. The numbers that appear afterwards are often rounded, never explained, and flanked by CTAs designed to route users straight into a lender's sales funnel.
We built Carfinance.org.nz because we think the arithmetic is the useful part. How much does a $25,000 loan cost per week at 9% over 5 years? That is a simple question with an exact answer, and handing over personal information to learn it is not a reasonable price to pay.
The calculator here is the whole product. The inputs are sliders, the weekly cost updates live, a different term or bigger deposit can be modelled in seconds, and the URL can be shared with a partner or co-buyer. If the numbers look right, the next step is applying with our partner. If not, walking away is the right call.

How we make money
We earn a commission from our finance partner when a visitor applies through Carfinance.org.nz and the partner approves them. Our rate with the partner is fixed, so we don't get paid more for bigger loans, longer terms, or higher rates. That matters because it means we have no financial incentive to recommend a particular loan shape to you.
The calculator's defaults (7% interest, 5 years, no deposit) are set to be a reasonable middle-of-the-market point for a secured used-car loan, not to flatter the partner's own rate. The guidance in our guides (deposit size, term trade-off, total-interest impact) is the same guidance we'd give a family member.
The calculator can be used without ever clicking through to the partner. Nothing on this site requires an application.
Our partner
Every "Get a rate" or "Apply" link on Carfinance.org.nz will route to a single vetted referral partner: a New Zealand-based loan comparison service that checks your application against multiple NZ lenders and presents the best-placed option, rather than charging you to shop the market yourself.
We are finalising the partner. The criteria are deliberate: a partner that compares a reasonable spread of NZ lenders (not just one bank's book), keeps the application short, charges no separate broker fee, and is a registered financial service provider. While the relationship is being finalised, the apply buttons open a notice that the finance partner is coming soon.
The partner name and link will appear on the partner page as soon as the arrangement is signed.
The calculator covers amount, deposit, rate, and term. The result stays on-device until the next step is a formal rate.
Disclaimer
A car loan is a commitment that runs for years, and repayments come out of the same pay cheque as everything else. Before committing, it is worth modelling the weekly and monthly cost against the household budget, which is what this site is built to help with. Borrowing at a level that stays comfortable on a bad week, not a good one, is widely regarded as the safer frame.
Carfinance.org.nz earns a commission from a partner brand when a visitor applies through this site and their application is approved. That commission is paid by the partner, not the applicant, and it does not influence the rate the lender offers. We refer every visitor to the same partner because they compare multiple New Zealand lenders on the applicant's behalf, so the recommendation is not driven by a sponsored deal. Every figure shown on this site is a modelled estimate based on the inputs entered; the actual rate, fees, and repayments are set by the lender after assessing the applicant's circumstances and own credit decision. Carfinance.org.nz is a calculator and information tool. We are not a lender, not a broker, and not a registered financial adviser. Any decision about whether a specific loan suits a specific situation is best made after talking with the lender, and for amounts that materially affect the household, with a registered financial adviser.
We are finalising our New Zealand finance partner. The calculator above is the whole tool, and the figures you have already worked out are yours to keep. Check back soon, the partner referral will go live here.
