The 20% Rule: Are You Flirting With the ‘Car-Poor’ Threshold?

For many households, a car payment is an unavoidable expense. Of course, when that payment starts consuming a large share of take-home pay, the ripple effects across the rest of your finances can be significant.

Financial experts explained to Moneylion what happens if your car payment is eating up 20% of your income.

It Eats Into Your Financial Buffers

Unless you're going to live in your car, 20% is way too high, said Howard Dvorkin, a CPA and chairman of Debt.com. The car payment is only one expense; there's also fuel, insurance and maintenance. "I've known clients who spent nearly 30% of their take-home pay on their car, once you factor in the inevitable repairs. That's how much financial experts say you should spend on housing costs."

Joe Giranda, automotive expert and director of sales and marketing for CFR Classic, echoed that concern and explained that cars are depreciating assets, so "dedicating a large percentage of your net income each month to something that loses value leads to the potential of missing out on more important opportunities in your financial journey with the money you are earning."

Other Budget Categories Start To Suffer

When transportation costs become too large, the rest of the budget often has to absorb the pressure.

"You're probably not saving money for life goals or emergencies," Dvorkin said. "And if something bad happens — an illness, an accident or even a major appliance breaks — then your budget is thrown in reverse."

Retirement contributions and emergency funds frequently get shunted off for later when vehicle costs dominate the budget, Giranda added.

A Debt Domino Effect Is Triggered

Another problem of a too-large car payment is that households may begin relying on credit cards to cover everyday expenses. Brit Simon, chief experience officer at National Debt Relief, said this dynamic is becoming increasingly common among borrowers.

"Auto loans increasingly show up in the financial challenges our clients face because the size of those payments nowadays is becoming a tipping point for other financial burdens," he said.

Simon explained that because transportation is essential, people often prioritize the car loan even when money gets tight and "credit cards then become the buffer for everything else — groceries, school expenses and emergencies."

Over time, this can lead to "revolving debt" that amasses significant interest.

Warning Signs You May Be 'Car-Poor'

A car that takes too big a chunk of your income can throw a household budget into disarray. Giranda said difficulty saving is often the first sign. Other signs include routine credit card usage or stress when unexpected repairs crop up.

"If maintaining a car is causing you to forego investing or securing your future financially, it is time to do the math again," he said.

Even more dangerous is if the cost of your car means putting off essential maintenance, Dvorkin said. "I've known clients who drove on bald tires and ignored warning lights because they didn't have the cash or credit limit to address those issues. That can be deadly."

When It Might Be Time To Reevaluate Your Vehicle

If transportation costs rise above recommended guidelines, experts said it may be worth reassessing the car itself.

"If you have a car payment that is greater than 15% of your income, Dvorkin advised, "get another car." He added, "I know we've been trained by mass media and Madison Avenue to think of our cars as extensions of ourselves, but really, they're just metal boxes on wheels. That metal box isn't a reflection of you."

Refinancing only makes sense if it lowers your interest rate, which often isn't available, he said.

The Bigger Budget Picture

A car is often necessary for work and daily life, but it should not dominate your financial picture.

For many households, the smartest move may simply be stepping back and asking whether the car still fits the life they want their budget to support.
