Our guide explains negative equity in car loans, how to avoid it, expert insights and practical tips to help you avoid financial difficulties from a car loan.

Updated 17 March 2024
Summary:
Negative equity is a common financial situation for anyone with a car loan. It's often described as being "upside down" and occurs when the balance owed exceeds the vehicle's current market value.
Negative equity is a straightforward concept but has implications for car owners. Many New Zealanders quickly find themselves underwater when buying a car, which, alongside car repayments, can become stressful.
We've published this guide to help explain why understanding negative equity is important if you're considering financing a car or have a car loan already.
Our guide covers:
Know This First: Getting out of negative equity takes commitment and financial sacrifices:

"Negative equity often occurs when a new car requires a small deposit. Given the ads in the Herald, Stuff, and other media promoting 'zero deposit' car finance deals, it's not hard to owe more than your car is worth when 100% loans appear to be the standard way of buying them.
New cars almost always lose a substantial part of their value quickly - sometimes as much as 20% in the first year. This depreciation combines with low deposit loans to ensure you owe more on the car than its current value. When you sign up for a long-term loan (such as six or seven years), the higher the risk of negative equity in the first few years of the loan.
Car loans are, for many New Zealanders, hugely financially crippling. If a financed car later becomes a liability, selling it despite having negative equity might be financially sensible if it's in poor condition and becoming a money pit due to extensive repairs. However, you'll need to find the money to settle the balance on your lender's terms.
Before signing any car loan contract, it's crucial to carefully consider the financial implications of low or no deposit car loans, especially when it comes to new cars. Cars sink in value fast - don't fall into the negative equity trap".

Depreciation, deposits and the loan term length cause negative equity in car loans. We explain these in detail to help you make an informed decision about a car loan.
1. Depreciation: The Silent Factor
2. Deposits: The Less You Offer, the Riskier the Car Loan
3. Loan Terms: The Longer, the Riskier (and Costly)

Determining if your car loan is in negative equity is straightforward. Start by finding the current market value of your car - there are several free tools available for this:
Know This: The values you receive will likely vary - MoneyHub's car valuation guide provides further guidance. Once you have an estimate of your car's current value, you'll need to subtract the balance remaining on your car loan. If the result is negative, meaning you owe more on the loan than your car's current value, you are in negative equity.
For example, if your car's current market value is $15,000, but you still owe $18,000 on your car loan. In this scenario:

Negative equity can have substantial financial implications, particularly when you're looking to sell or trade-in your car, for the following reasons:
The 'best' car loan has a low interest rate, affordable monthly payments and an outstanding balance well below your car's value. Our suggested methods minimise the risk of having a car loan that drags you under:

Most people who owe more to their car lender than the car's worth will continue to make repayments until the loan is repaid in full. However, if you're looking to sell your car with finance owing, you'll want to maximise the sales price to minimise the shortfall of the car loan.
For most people, this will involve listing the car and selling it privately, given that it's likely to get a higher price than trading it in at a dealership.
Warning: We strongly suggest resisting the temptation to roll the negative equity into a new car loan. This only increases your debt and total interest costs and can lead to a cycle of negative equity. While few lenders in New Zealand offer this arguably dangerous debt, rolling the negative equity may be tempting to fast-track with a purchase.
If you have negative equity and your car is stolen or written off, the situation can become complex and financially stressful because the loss is 'realised,' meaning you must immediately deal with the cash shortfall while arranging another car. The standard process is as follows:

While negative equity doesn't directly affect your credit profile or history, how you manage your car loan does. If you continue to make timely payments on your car loan despite having negative equity, your credit history remains unaffected.
However, if you struggle with payments or default on the loan, this will be added to your credit profile and negatively impact your future borrowing applications.
Refinancing a car loan with negative equity is challenging but not impossible. You'll need to find a lender willing to refinance the loan amount that exceeds the car's value.
This will almost always come with higher interest rates and stricter terms, meaning it may not be cost-effective.
Electric and hybrid vehicles depreciate differently than traditional cars, which can impact how quickly you find yourself in negative equity (and the extent of it).
When financing such vehicles, it's crucial to consider their specific depreciation trends and market demands.
