Car finance with variable income in New Zealand

The short answer

Uneven income does not close the door on a car loan, but it changes what the lender wants to see. A permanent employee shows one payslip and the lender multiplies it. When your pay moves, the lender looks across many weeks, asks what the quietest ones looked like, and wants to know if the pattern is likely to continue.

Our pages on casual workers and gig workers cover those job types. This page is for anyone whose pay moves, whatever the job: seasonal work, commission, tips, rostered extras, mixed jobs, trades and cash. The focus is on what counts, how to work out a number you can trust and how to choose a loan that holds up in a bad month.

Fair Finance is a referral service, not a lender and not a broker. One application and one soft credit check go to a panel of approved New Zealand lenders. We are paid by the lender only if a loan settles, and that never changes your rate. Nobody can promise approval.

What lenders are really asking

Before lending, a lender must make reasonable inquiries and be satisfied you can repay without substantial hardship. Consumer Protection lists asking for evidence of your income and asking about your expenses as examples. The Responsible Lending Code, revised on 31 July 2024, gives guidance on how lenders can assess affordability, and following it is not compulsory but can be evidence of compliance.

With uneven pay, that comes down to three questions:

1. How much, on average? Over a long enough period to smooth out the spikes.
2. How low does it go? The worst month tells the lender more than the best one.
3. Is it likely to continue? A pattern that has run for a year says more than one good quarter.

Kinds of variable pay, and what proves each

Different kinds of uneven pay are read differently.

Seasonal work. Harvest, tourism, holiday trade and construction have busy and quiet stretches. The lender needs a full cycle, so twelve months of statements is the strongest evidence. If you work seasonally every year, a prior year’s statements show the pattern is repeatable.

Commission and piece rates. A base wage with commission on top is easier than commission alone. Payslips that itemise the base and the commission let the lender count the base with more confidence and the commission with caution.

Tips. Tips that go into your account regularly can be shown on statements. Tips kept in a jar and never banked cannot. If you are paid mostly in tips, the statements matter even more.

Overtime and extra shifts. Employment New Zealand says pay for extra work must be agreed and written into the employment agreement. A lender is more comfortable counting extras that are part of your normal pattern, and less comfortable with a burst that happened once.

Several small jobs. Two part-time jobs and some weekend work can add up, but each source needs its own evidence.

Trade and self-employed work. Jobs come in waves, and invoices get paid late. Our page on self-employed car loan documents lists what to collect, and car finance for contractors covers contract income.

Cash income

Some work is paid in cash, and this is where people get stuck. A lender can only count income it can verify, and cash that never goes near a bank account leaves nothing to verify.

There is also a tax side. Inland Revenue says to record every job and declare every dollar. It says cash that is deposited, moved to another account or spent on loan instalments and other costs leaves a trail, and that it can access information from banks and other sources. People who have not declared past cash jobs can correct earlier returns through Inland Revenue’s Get it right service. We cannot give tax advice, so talk to an accountant.

For the loan, the practical steps are:

• Bank the cash and record it. A clear run of declared, deposited income over several months is what a lender can use.
• Keep your records. Inland Revenue says to keep records of cash and non-cash sales and expenses for at least seven tax years.
• Do not hand a lender a figure you cannot show. An application that does not match the evidence tends to fall over.
• Give it time. If your cash income has been unrecorded, the honest route is to put it in order and then apply with a few months of clean statements.

What you can count on

Part of your income may be firmer than it feels. Employment New Zealand says an availability clause is valid only if the agreement has agreed hours with set hours, the employer has genuine reasons on reasonable grounds and you get reasonable compensation. Without a valid clause you can decline work outside your set hours, and your employer cannot disadvantage you for refusing. That means your set hours are the firm base, and anything above them is extra.

It helps to know which side of that line your pay falls on. If your agreement has set hours, a lender can reasonably count them. Hours above that are less certain, and a careful lender will treat them that way. Keep a record of your shifts. Employers must keep accurate time records, which can help if there is ever a dispute about hours.

Work out your quiet-month number

Before a lender does it for you, do it yourself. This protects you as much as it helps the application.

1. List twelve months of income from your statements, month by month.
2. Find the average. Add them up and divide by twelve.
3. Find the low. Note your lowest month and your lowest three-month stretch.
4. Subtract tax and business costs. If you are self-employed, set aside what you owe. Inland Revenue says you are a provisional taxpayer if your last return showed residual income tax over $5,000, so tax can be a large monthly sum.
5. Subtract your fixed costs. Rent, power, phone, food, insurance, existing debts, childcare.
6. See what is left in the low month. That is the money that has to carry the car loan and its running costs.

If the loan only works in your average month, it is too tight. Our guide to minimum income for car finance explains how lenders think about the threshold.

A worked example (illustrative numbers only)

Say a person earns the following over a year, after business costs and tax. The figures are made up to show the method.

Quarter	Monthly take-home
Busy quarter	$4,400
Normal quarter	$3,400
Normal quarter	$3,200
Quiet quarter	$2,100

The average is about $3,275 a month. The quiet quarter is $2,100. Fixed costs are $1,550 a month, which leaves about $1,725 in an average month and $550 in the quiet one.

Now look at a $14,000 loan at an illustrative 20% over four years. The repayment is roughly $424 a month. Running costs for insurance, registration, warrant of fitness, fuel and servicing come to, say, $300.

	Average month	Quiet month
Left after fixed costs	$1,725	$550
Loan repayment	$424	$424
Running costs	$300	$300
Left over	$1,001	-$174

In an average month the loan fits comfortably. In the quiet quarter it does not. A smaller loan, a cheaper car or a larger deposit would fix that. So would a financial buffer saved in the busy months. The shortfall is exactly what a careful lender looks for, and exactly what you want to see before you sign.

The repayment calculator lets you test your own numbers. Real rates, fees and terms vary by lender and by borrower.

Choosing a loan that holds up

For variable income, the shape of the loan matters as much as the price.

• Fixed repayments. The amount stays the same even when your pay does not, so you can plan.
• No balloon. A balloon payment lowers the regular figure but leaves a lump sum to find at the end. Our glossary entry on balloon payments explains the risk.
• A term you have tested. A longer term lowers the repayment and raises the total cost. Sorted suggests asking for the total dollar cost of the loan.
• A repayment frequency that matches your pay. If you are paid weekly or fortnightly, a weekly or fortnightly repayment can be easier than monthly. See car finance weekly payments.
• A buffer. Build a small cushion in the busy months if you can.
• Check the early repayment fee. If your income jumps, you may want to pay the loan off early. See pay off your car loan early.

If your income drops

Contact the lender early. Consumer Protection says that if you are struggling, options can include a longer repayment period, a payment holiday or interest-only payments. If you do not qualify for help, you can still ask the lender, get free help from a financial mentor or contact the Insolvency and Trustee Service. Returning the vehicle is possible, but you still owe the money. See our guide to struggling to pay your car loan.

Red flags

• A weekly price with no total. Ask for the total repayable, with every fee, in writing.
• A balloon sold as the way to afford the car. A low payment now can mean a big bill later.
• A lender who does not ask about your income. Lenders must make reasonable inquiries. Be careful with anyone who skips them.
• A promise of approval before they have seen your records. Nobody can make that promise.
• A fee before the loan settles. Be wary of any upfront payment.
• Advice to overstate your income. Never do it. The application should match your evidence.

How Fair Finance helps

Fair Finance is a referral service, not a lender. One application and one soft credit check go to a panel of approved New Zealand lenders, so you can see options without a hard check at each one. The lender decides case by case. We are paid by the lender only if a loan settles, and that never changes your rate. Use the quick check to start.
