Vehicle & Purchase Details

Vehicle Type

New cars often have lower interest rates. Used cars may have higher rates but lower purchase price. EVs may qualify for special finance deals.

Vehicle Price (NZD)

Total purchase price of the vehicle. For dealer purchases, this includes GST (15%).

Deposit (NZD)

Most NZ lenders prefer 10-20% deposit for used vehicles and up to 30% for new cars. Larger deposits reduce interest costs.

Trade-In Value (NZD)

Value of your current vehicle being traded in. This reduces the amount you need to finance.

Financial Disclaimer: This is an illustration of vehicle finance costs, not a quote or an offer of credit. Ask any dealer or lender for the total amount payable and the annual interest rate, and compare those rather than the weekly or monthly figure. Full disclaimer.

Calculation type: Exact calculation. Figures are taken from Consumer Protection, Ministry of Business, Innovation and Employment (NZ) — see sources below.

Formula & methodology

Formula used

Amount financed

P = vehicle price − deposit − trade-in + fees

Your deposit and trade-in reduce what you borrow; establishment and dealer fees added to the agreement increase it.

Regular repayment

M = P × i × (1 + i)^n ÷ [(1 + i)^n − 1]

The level payment that clears the financed amount and its interest over the term.

Repayment with a balloon

M = (P − B ÷ (1 + i)^n) × i × (1 + i)^n ÷ [(1 + i)^n − 1]

Where a final lump sum is deferred, only the balance above its present value is amortised — the monthly cost falls but a large payment remains at the end.

Variable definitions

Symbol	Meaning	Unit
P	Amount financed. Price less deposit and trade-in, plus fees rolled into the agreement.	NZD
B	Balloon / residual. A lump sum deferred to the end of the agreement.	NZD
i	Periodic rate. Annual rate divided by the number of payments a year.	decimal

Step-by-step calculation

1. Work out what is being financed
Deduct deposit and trade-in from the price, then add fees and any add-ons being financed.
2. Discount any balloon to present value
A deferred lump sum is brought back to today before the regular payment is calculated.
3. Apply the amortisation formula
Produces the level repayment for the chosen term and frequency.
4. Total the real cost
Add every repayment plus any balloon, then subtract the amount financed to see the cost of credit.

Limitations

Depreciation, insurance, registration, warrant of fitness, servicing and fuel are excluded. These running costs often exceed the finance cost over the life of the vehicle.
A balloon lowers the regular payment but not the debt, and interest accrues on the deferred amount throughout the term.
On long terms you can owe more than the vehicle is worth for much of the agreement, because cars depreciate faster than the loan reduces.
Payment protection insurance, extended warranties and mechanical breakdown cover are treated only as amounts added to the balance.
Advertised rates are indicative; the rate you are offered depends on your credit assessment and the security taken over the vehicle.

Help & FAQs

Frequently Asked Questions

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

Why is the dealer's repayment different from this estimate?

Tap to view the answer

Dealer quotes typically fold in establishment fees, payment protection insurance, extended warranties and sometimes a balloon payment. This calculator applies the rate you enter to the amount financed. Ask for the total amount payable and the annual rate, then compare.

Does a longer term make a car more affordable?

Tap to view the answer

It lowers the monthly payment but raises the total cost, because interest accrues on the balance for longer. On long terms you can also owe more than the car is worth for much of the agreement, since vehicles depreciate faster than the loan reduces.

What is a balloon payment and should I take one?

Tap to view the answer

A balloon is a large lump sum deferred to the end of the agreement. It cuts the monthly figure but the debt has not gone away, and interest is charged on that deferred amount throughout. Only take one if you have a concrete plan for paying or refinancing it.

Is dealer finance or a bank loan cheaper?

Tap to view the answer

It depends on the rate and fees rather than the source. Dealer finance is convenient and occasionally subsidised at very low promotional rates, but it can be more expensive once fees and add-ons are counted. Compare the total repayable on both.

What does this calculator leave out?

Tap to view the answer

Depreciation, insurance, registration, warrant of fitness, servicing, tyres and fuel. Those running costs frequently exceed the finance cost over the life of the vehicle.

How to Use This Calculator

Enter vehicle and loan details

Enter the vehicle price, your deposit, trade-in value, and loan term.

Select interest rate

Use current market rates (6.5-14.9% APR). Bank loans are typically lower than finance company rates.

Choose repayment frequency

Weekly, fortnightly or monthly. Fortnightly matches NZ pay cycles and reduces interest.

Add optional balloon payment

If you want lower regular repayments, add a balloon payment (10-30% of the loan).

Include running costs

Add insurance, registration, WoF, servicing, and fuel to see the full cost of ownership.

Review CCCFA affordability

Enter your income and expenses to check if you can comfortably afford the loan.

Key Tips

✓
A larger deposit reduces your loan amount and total interest – aim for 20% if possible.
✓
Fortnightly repayments reduce total interest by making an extra payment per year.
✓
Secured loans (against the vehicle) have lower rates than unsecured personal loans.
✓
Check the CCCFA affordability – lenders must ensure you can comfortably repay the loan.
✓
Budget for running costs – they can add $3,000-6,000/year to your total vehicle costs.
✓
EVs have lower running costs but higher purchase price – compare total cost of ownership.
✓
Shop around – interest rates vary significantly between banks and finance companies.
✓
Avoid long loan terms (7+ years) – they increase total interest and reduce equity.
✓
A balloon payment reduces regular repayments but requires a lump sum at the end.
✓
Refinance if rates drop – you may save hundreds in interest over the loan term.

New Zealand Auto Finance Guide (2026)

How car loans work in New Zealand

A car loan (auto finance) is a secured or unsecured loan used to purchase a vehicle. Most NZ car loans are secured against the vehicle, meaning the lender can repossess the car if you default. Secured loans typically have lower interest rates than unsecured personal loans.

2026 car loan interest rates

For 2026, typical car loan rates range from 6.5% to 14.9% APR. Major banks (ANZ, ASB, Westpac, BNZ) offer secured rates around 7-9% for new vehicles. Finance companies may charge 10-14.9% depending on credit profile, vehicle age, and loan amount.

Deposit requirements

Most NZ lenders prefer a deposit of 10-20% for used vehicles and up to 30% for new cars. A larger deposit reduces your loan amount, lowers interest costs, and improves approval chances under CCCFA rules. Some lenders offer 100% financing, but these often have higher rates.

Balloon payments explained

A balloon payment is a lump sum due at the end of the loan term. It reduces your regular repayments but means you need to pay a large amount at the end. Typical balloon percentages range from 10-30%. Balloon payments are common for new vehicle finance.

Weekly vs fortnightly vs monthly repayments

Fortnightly repayments align with common NZ pay cycles and result in 26 payments per year instead of 12 monthly payments. This can shorten your loan term and reduce total interest. For a 5-year loan, fortnightly repayments can save hundreds of dollars in interest.

GST on vehicle purchases

Vehicle purchases from dealers include 15% GST in the price. Private sales between individuals do not attract GST. Registered businesses can claim GST back on vehicle purchases and running costs for IRD purposes. This calculator includes GST in the vehicle price by default.

CCCFA – responsible lending rules

The Credit Contracts and Consumer Finance Act (CCCFA) requires lenders to assess whether you can afford the loan. This calculator checks affordability against the income and expenses you enter. A lender goes further: it will verify your figures and apply its own living-cost benchmarks, including an allowance for each dependent, so its assessment can be stricter than this one.

Running costs of car ownership

In addition to loan repayments, budget for: Insurance ($800-1,500/year), Registration/Rego ($200-400/year), WoF ($50-100/year), Servicing ($400-1,500/year), Fuel ($2,000-3,000/year), and parking ($500-2,000/year depending on city).

Electric vehicle financing

EVs may qualify for special finance deals with lower interest rates. Running costs are significantly lower (fuel $500-1,000/year, maintenance $300-600/year). This calculator includes EV as a vehicle type with adjusted cost benchmarks.

Location cost differences

Costs vary significantly across NZ cities: Auckland (higher insurance, parking, fuel), Wellington (moderate costs, higher parking in CBD), Christchurch (lower costs overall). This calculator adjusts running costs based on your location.

Refinancing and early repayment

You can refinance your car loan to get a lower rate if interest rates drop or your credit improves. Early repayment fees (break fees) may apply. Check your loan contract before making extra payments.

Disclaimer

This calculator provides estimates for educational purposes. Actual loan rates, fees, and eligibility depend on the lender, your credit profile, and CCCFA assessments. Always consult a financial advisor or broker for personalised advice.
