How Negative Equity Works on Car Loans & How to Avoid It

Negative equity occurs when your car value drops faster than you pay down the loan balance. Several factors contribute to this common situation.

New car depreciation is the biggest one. A new car can lose 10-20% of its value the moment you drive it off the lot, and 30-40% within the first year. If you made little or no down payment, you are immediately upside down because the car is already worth less than you paid for it.

Long loan terms make the problem worse. With a 72 or 84-month loan, your monthly payments are lower, but you build equity much more slowly in the early years. More of each payment goes toward interest at the beginning, so the principal balance drops slowly while the car value drops quickly.

Low or zero down payment is another factor. If you put nothing down, you are financing the full purchase price plus taxes, fees, and maybe even extended warranties or other add-ons. The loan starts higher than the car actual value right from the beginning.

Certain vehicles depreciate faster than others. Luxury cars, electric vehicles (historically), and less popular models can lose value more quickly. Vehicles from brands with strong reputations for reliability and resale value — like Toyota and Honda — tend to hold their value better, reducing the risk of negative equity.

Negative equity is a problem because it limits your options and can cost you money in certain situations. Here is why it matters.

If you want to sell or trade in your car, you have to deal with the negative equity. If you trade in at a dealership, they might roll the negative equity into your new loan, meaning you start your next car loan already owing more than the new car is worth. This keeps the cycle going.

If you sell privately, you have to pay the difference out of your own pocket. If you owe $18,000 and the car is only worth $15,000, you need to come up with $3,000 to pay off the loan before you can transfer the title to the buyer.

If your car is totaled in an accident or stolen, insurance only pays the current market value of the car, not what you owe. If you are upside down, you still have to pay the remaining loan balance even though you no longer have the car. This is where gap insurance comes in — it covers the difference between the insurance payout and what you owe.

Negative equity also makes refinancing harder. Most lenders want you to have at least some equity, or at the very least not be significantly underwater, before they approve a refinance. If you are deeply upside down, your options are limited.

That said, if you plan to keep the car until you pay off the loan and you do not have any plans to sell or trade it in, negative equity might not affect you much day to day. You still make the same monthly payments either way. The problem only arises when you need to get out of the loan early.

Figuring out whether you have positive or negative equity is straightforward: you compare your current loan balance to your car current market value.

Your loan balance is the amount you still owe on the car. You can find this on your most recent loan statement or by logging into your lender online portal. Make sure you get the current payoff amount, which might be slightly different from the principal balance shown on your statement due to interest accrual.

Your car value is a bit trickier because it depends on factors like mileage, condition, location, and equipment. You can get estimates from sources like Kelley Blue Book (KBB), Edmunds, or NADA Guides. These websites let you enter your car details and get estimated trade-in value, private party value, and dealer retail value.

For calculating equity, the trade-in value or private party value is usually the most relevant, depending on how you plan to sell. Trade-in is what a dealer would give you, which is lower than what you could sell for privately.

Once you have both numbers, subtract the loan balance from the car value. If the result is positive, you have equity. If it is negative, you are upside down.

For example: if your car is worth $15,000 and you owe $18,000, you have negative equity of $3,000. If the car is worth $15,000 and you owe $12,000, you have positive equity of $3,000.

Our negative equity car loan calculator makes this easy and also shows projections for how your equity will change over time.

If you are currently upside down on your car loan, you have several options for getting back to positive equity. The best approach depends on how underwater you are and your financial situation.

The simplest strategy is to keep the car and keep making payments. Over time, you pay down the principal while the depreciation rate slows down. Cars depreciate fastest in the first few years, so after that, the value drops more gradually while you keep paying down the loan. Eventually you cross into positive equity.

Making extra principal payments speeds this up. Every dollar you put toward extra principal reduces your loan balance and helps you build equity faster. Even $50-$100 extra per month can make a meaningful difference over time.

If you need to get out of the car sooner, you have a few options. You can pay the difference out of pocket — if you owe $3,000 more than the car is worth, you write a check for $3,000 when you sell or trade it in. This cleans the slate but requires having the cash available.

You could also roll the negative equity into a new loan, but this is generally not advisable. You end up paying interest on that negative equity for years, and you start the new loan already underwater. It perpetuates the cycle and can cost you thousands in extra interest.

A lease assumption or transfer is sometimes possible if someone else takes over your lease. This works for leases more than loans, though some lenders may let someone assume your loan with credit approval.

Finally, as a last resort, you could sell the car and take out a personal loan for the remaining balance. Personal loan interest rates are often higher than auto loan rates, but it does get you out from under the car and the negative equity.

The best way to deal with negative equity is to avoid it in the first place. There are several steps you can take when buying your next car to minimize the risk of going upside down.

First, make a substantial down payment. Aim for at least 20% down on a new car and 10% on a used car. This immediately gives you equity and offsets the initial depreciation hit. If you can put even more down, that is even better.

Second, choose a shorter loan term. 60 months or less means you build equity faster and pay less interest overall. While 72 or 84-month loans have lower monthly payments, they also mean you stay underwater longer and pay thousands more in interest.

Third, pick a vehicle that holds its value well. Brands like Toyota, Honda, Subaru, and Porsche typically have strong resale value. Research depreciation rates before you buy. EVs historically depreciated faster, though that gap has been narrowing in recent years.

Fourth, avoid rolling negative equity from a previous car into your new loan. This is a common trap that keeps people perpetually underwater. If possible, pay off any negative equity from your old car before buying the next one.

Fifth, skip the unnecessary add-ons. Extended warranties, paint protection, fabric protection, gap insurance, and other dealer add-ons get financed into the loan, increasing the amount you owe from day one. Some of these might have value, but they also push you closer to negative equity.

Gap insurance is a type of coverage that pays the difference — the gap — between what your car is worth and what you owe on the loan if the car is totaled or stolen. It is specifically designed to address the negative equity problem.

Here is how it works: suppose you buy a new car for $30,000 with no down payment. A year later, the car is worth $22,000 but you still owe $26,000. If the car is totaled in an accident, your insurance company pays you $22,000 (the actual cash value). But you still owe $26,000 on the loan. Without gap insurance, you have to come up with $4,000 out of pocket to pay off the loan.

With gap insurance, the gap coverage pays that $4,000 difference, so you are not left owing money on a car you no longer have. That is why gap insurance is especially important for new cars with low down payments or long loan terms — situations where negative equity is likely.

Gap insurance is relatively inexpensive. Some lenders charge a few hundred dollars added to the loan, while insurance companies might charge $20-$40 per year as an add-on to your regular policy. When you consider the thousands it could save you in a worst-case scenario, it is often worth it for at least the first couple years of ownership.

You typically do not need gap insurance for the entire loan term. Once you have positive equity — when the car is worth more than you owe — gap insurance is no longer necessary. You can cancel it at that point if you are paying for it separately.

Many dealerships offer gap insurance when you buy the car, but you can often get it cheaper from your regular auto insurance company. Shop around before buying from the dealer.
