5 reasons a $1,000 monthly car payment can be a costly mistake

It was once common to joke about owning a $1,000 car. Now, financial experts are warning about the risk of a $1,000 monthly car payment.

Edmunds says more than 20% of new-car borrowers are now taking on monthly payments in four figures. The average monthly payment for a new vehicle reached $787 in the third quarter of 2026.

Car payments have climbed as buyers finance larger amounts over longer periods. The average new-vehicle loan was $44,664 in the third quarter, and more than one-quarter of new-car loans now stretch to seven years or longer.

According to Ivan Drury, director of insights at Edmunds, a $1,000 car payment “crosses a threshold in our minds that seems unfathomable to many consumers.”

Many households only make one monthly payment that reaches that level: rent or a mortgage. But a home and a car are not the same kind of asset. One usually gains value, while the other usually loses it.

Here are five reasons a $1,000 car payment may be a bad financial move.

1. Cars lose value

In strict terms, a car “is not an investment,” says Ernie Wingard of Capital Choice Financial Group in North Richland Hills, Texas.

Vehicles generally depreciate as they get older. According to LendingTree, a new car typically loses about 20% of its value after one year and 60% after five years.

“You’re paying a lot more for an asset that’s going to depreciate,” says Chuck Bell, a financial policy advocate at Consumer Reports. “Is that a good value for you, versus buying a used car, a car that’s coming off a lease?”

2. It may violate the 10% guideline

Financial advisers often use rules of thumb. One is the 20/4/10 guideline for car buyers, which says a vehicle is probably affordable if you meet these three conditions:

• You can make a down payment of 20% or more of the car’s price.

• You finance the purchase with a loan term of four years or less.

• Your monthly car costs, including the loan payment, stay under 10% of your income.

That standard may be hard to follow now, since the average new-car loan has stretched to 67 months, or more than five years.

To carry a $1,000 monthly payment and still follow the 10% rule based on take-home pay, “You’d have to be making over $120,000 a year,” says Kimberly Palmer, a personal finance expert at NerdWallet.

Even so, experts advise trying to stay within some version of the 10% rule.

Insurance, fuel and repairs can also raise total ownership costs quickly. Those expenses could push a $1,000 monthly payment to $1,500 a month in all.

One goal is to keep total monthly car costs below 15% of take-home pay, or keep the payment alone under 10% of that amount.

3. The money could be saved or invested instead

A $1,000 car payment goes toward both principal and interest on a loan. The average new-car loan carries an annual interest rate of 7%.

But what if the same amount were earning 7% a year? Based on recent market performance, investing $1,000 a month in stocks could do at least that well.

If you put $1,000 a month into a brokerage account earning 7% annually, you would have about $73,000 after five years, according to a NerdWallet calculator.

That money could also help build an emergency savings fund. Financial planners say households should have enough emergency savings to cover three to six months of expenses.

Palmer says a four-figure car payment “makes it harder to build up an emergency fund, or any other kind of long-term savings.”

4. It reduces financial flexibility

A large car payment takes up more of the household budget, leaving less money for everything else.

“It reduces your financial resilience,” Palmer says. “Anything that pops up, you’re less able to deal with it.”

Other monthly bills are also likely to keep climbing.

“You need some room in your family budget to handle other things that are increasing in cost,” Bell says.

If your household income takes a hit, making a $1,000 car payment could become difficult.

“If you fall behind, you’re going to be in a very bad position going forward,” Drury says.

More drivers are also ending up “underwater” on car loans, meaning they owe more than the vehicle is worth, according to trade-in data.

That means if you can no longer keep up with the payments, selling the car may not be enough to get you out of debt.

5. It can make other borrowing harder

A large auto loan with a high monthly payment can push up your debt-to-income ratio, which compares what you owe with what you earn.

A higher debt-to-income ratio can make it harder to qualify for another loan, including a mortgage.

“Every dollar spent on a car loan counts against your debt-to-income ratio,” Bell says.

“Depending on what your income is,” he adds, “a $1,000 monthly car payment could significantly reduce how much mortgage you qualify for, because lenders see it as an ongoing financial obligation.”
