Owning a new car averages about $11,577 a year. But the number that scares people, fuel and repairs, is not where the money goes. Most of it is depreciation and finance, two costs you never get a bill for and most people never think about. Once you see the real split, it is clear which costs are fixed, which are optional, and how buying used and doing a few jobs yourself saves thousands a year.
Reviewed July 2026, using AAA's latest annual figures. Your costs depend on the car, mileage, location and whether you finance.
When people budget for a car they think about fuel, insurance and the occasional repair. Those matter, but they are the middle of the list. The biggest cost by far is depreciation, the value the car quietly loses every year, and after that comes the interest on the loan. Neither shows up as a monthly bill, so both get ignored, and both are where the real money is. Get those two right and the rest is manageable.
| Cost | Typical per year | How controllable |
|---|---|---|
| Depreciation | ~$4,334 | High. The biggest cost. Buying used and keeping the car for years cuts it the most. |
| Fuel | ~$2,000–2,500 | Medium. Depends on the car's economy, your mileage and gas prices. |
| Insurance | ~$1,500–2,000 | Medium. Shop every year; loyalty is usually punished, not rewarded. |
| Finance charges | ~$1,131 | High. Finance less, put more down, or buy a cheaper used car outright. |
| Maintenance & repairs | ~$1,000–1,500 | High. The easy jobs (oil, wipers, filters) are cheap to do yourself. |
| Registration, taxes, fees | ~$700 | Low. Largely fixed by your state and the car's value. |
Figures are typical US averages for a new vehicle (AAA); a used, paid-off car can cost less than half as much per year, mostly because depreciation and finance shrink.
A new car loses about 40% of its value in three years. Buy one that is two or three years old and the first owner has already taken that hit, while you pay far less and lose value more slowly. This one choice saves more than everything else combined.

Oil change, DIY vs shop → Wiper blade cost →Fuel is a few thousand a year and swings with the car and your mileage. Work out your actual cost per mile and per trip, and let it steer your next-car choice as much as the sticker price does.
Fuel cost calculator →Insurers quietly raise renewals, banking on you not checking. Get fresh quotes each year and be ready to switch; the same cover is often hundreds cheaper elsewhere. Bundling and a higher deductible can cut it further.

About $11,577 a year for a new vehicle (AAA), roughly $965 a month, but that is dominated by depreciation (~$4,334) and finance (~$1,131), not fuel and repairs. A used, paid-off car often costs half as much or less.
Depreciation, by far, and the one people ignore because there is no bill for it. A new car loses ~40% of its value in three years. Reducing depreciation, by buying used and keeping the car, is the single biggest saving.
Buy slightly used, finance as little as possible, keep the car long after payoff, do simple maintenance yourself (oil, wipers, filters), and shop insurance every year. Together that saves several thousand a year.
Usually much cheaper, because the previous owner absorbed the fastest depreciation and you finance less. Used cars can need more repairs, but for most people the depreciation and finance savings far outweigh it, especially on a reliable model.
