How much should I spend on a car?
The rule of thumb in dollars for your pay, what a car really costs once gas and insurance are counted, and what households spend on getting around.
Checked October 26, 2026
10% of pay, in dollars
| Monthly pay before tax | All car costs, 10% | A year |
|---|---|---|
| $4,000 | $400 | $4,800 |
| $5,000 | $500 | $6,000 |
| $6,000 | $600 | $7,200 |
| $8,000 | $800 | $9,600 |
| $10,000 | $1,000 | $12,000 |
The payment is whatever is left after insurance, gas and upkeep. To see what car price that allows with 20% down and a 4-year loan, use the 20/4/10 calculator.
What a car really costs a year
| Cost | Average household, 2024 | A month |
|---|---|---|
| Buying vehicles (net outlay) | $5,337 | $445 |
| Gas and other fuels | $2,645 | $220 |
| Other vehicle costs | $4,206 | $351 |
| of which insurance | $1,993 | $166 |
| of which loan interest | $418 | $35 |
| Together | $12,188 | $1,016 |
The price is only part of it. For the average household, insurance, repairs, fees and interest came to $4,206 a year, close to what it spent buying the cars themselves. Price those before you pick a payment.
A car inside the whole budget
Fidelity counts transportation among the must-haves, which together should take no more than 60% of take-home pay. A car that fits 10% of gross can still crowd rent and food if those are already high. Check the car against what is left after rent, not against your pay alone. The rent page shows how that part adds up.
Ways to keep the number down
- Put more down. 20% down means a smaller loan and less interest.
- Keep the loan short. 4 years or less: a longer loan lowers the payment but adds interest and keeps you paying for longer.
- Get the insurance quote first. It counts toward the 10% from the first month.
- Weigh leasing. See lease vs buy.
Questions people ask
How much should I spend on a car?
A common rule, 20/4/10, keeps all your car costs at no more than 10% of your monthly income before tax: the payment, insurance, maintenance and fuel together. On $6,000 a month that is $600 for everything.
What is the 20/4/10 rule?
Put 20% down, borrow for 4 years or less, and keep transportation costs at or under 10% of gross monthly income. Chase describes it this way.
How much should you spend on a car payment?
Less than the whole 10%. The 10% has to cover insurance, gas and upkeep too, so the payment is what is left after those. If insurance and gas run $250 a month on $6,000 of pay, the payment fits in $350.
How much do people spend on cars a year?
In 2024 the average U.S. household spent $13,318 on transportation, 17% of its spending: $5,337 on buying vehicles, $2,645 on gas and other fuels, and $4,206 on other vehicle costs, including $1,993 of insurance, per the Bureau of Labor Statistics.
Is 10% of income for a car too low?
It is a guideline. The average household's transportation spending in 2024 was 12.8% of average income before tax, so many people spend more. Going over it means less for saving, which is the trade to decide on purposely.
How should a couple budget for two cars?
Hold both cars together to the 10% line of your combined income, then split the cost the way you split other shared bills, by income or 50/50. A car only one of you drives can stay that person's own cost.
