The total cost of driving breaks into two parts: what you pay upfront and what you pay per mile
A new car costs roughly $400 to $600 per month in payments, insurance, registration, and maintenance combined. A used car costs less upfront but may cost more per mile if repairs pile up. Then you add fuel, tolls, and parking on top of that. The real number depends on what car you own, how far you drive, where you live, and how old the vehicle is. There is no single "cost to drive" — but there are ways to calculate your own.
Most people underestimate their driving costs because they only count gas. They miss insurance, which often costs more than fuel. They forget about maintenance until something breaks. They don't account for depreciation — the value your car loses every month you own it. When you add all of it together, the cost per mile is usually between 50 cents and $1.50, depending on the vehicle.
Key Takeaways
- Fixed costs (insurance, registration, loan payments) stay roughly the same whether you drive 5,000 miles or 15,000 miles per year.
- Variable costs (fuel, maintenance, tires) rise with every mile you drive, and maintenance costs are often higher than drivers expect.
- A new car typically costs $0.60 to $1.00 per mile; a used car paid in cash might cost $0.50 to $0.80 per mile depending on repair history.
- Insurance is usually your second-largest driving expense after fuel, and rates vary dramatically by age, location, driving record, and vehicle type.
- The cheapest way to reduce driving costs is to drive less; the second-cheapest is to own a reliable used car outright.
Fixed costs that don't change with mileage
Fixed costs are what you pay whether you drive 100 miles or 10,000 miles in a month. They include your car payment (if you have a loan), insurance, registration and tags, and roadside information if you pay for it separately.
A car payment on a new vehicle runs $300 to $500 per month depending on the price and your down payment. A used car loan is typically $150 to $350 per month. If you own the car outright, you have no payment, but you still have insurance. Insurance costs $100 to $250 per month for most drivers, though it can be higher if you are under 25, have accidents on your record, or live in a high-cost urban area. Registration and tags cost $100 to $300 per year in most states, which works out to $8 to $25 per month. Some states charge more; some charge less.
Add these together and your fixed costs are probably $400 to $700 per month before you buy a single gallon of gas. If you finance a new car, you are closer to $700. If you own a used car outright, you might be at $100 to $150 just for insurance and registration.
Variable costs that rise with every mile
Variable costs scale with how much you drive. The main ones are fuel, maintenance, tires, and repairs.
Fuel is the most visible cost. At $3.00 to $3.50 per gallon (prices vary by region and change over time), a car that gets 25 miles per gallon costs about 12 to 14 cents per mile in fuel alone. A truck or SUV that gets 18 miles per gallon costs 17 to 19 cents per mile. A hybrid that gets 50 miles per gallon costs 6 to 7 cents per mile. These numbers shift when gas prices rise or fall.
Maintenance and repairs are the variable cost most people underestimate. The IRS estimates that routine maintenance — oil changes, air filters, brake pads, coolant flushes — costs about 4 cents per mile for an average car. That sounds small until you drive 12,000 miles in a year and realize you have spent $480 on maintenance alone. Major repairs (transmission, engine work, suspension) can cost thousands and happen unpredictably. A used car with 100,000 miles on it will have higher maintenance costs than a new car. A car with a history of poor maintenance will cost more to repair than one that was serviced regularly.
Tires are a separate line item. A set of four tires costs $400 to $1,200 depending on the vehicle and tire quality. If they last 40,000 miles, that is 1 to 3 cents per mile. If they last 60,000 miles, it is less. Tires on trucks and performance cars cost more.
Depreciation: the cost of owning instead of renting
When you buy a car, it loses value the moment you drive it off the lot. A new car loses 15 to 20 percent of its value in the first year. After that, it loses 10 to 15 percent per year for the next few years. A $30,000 car might be worth $24,000 after one year and $18,000 after three years. That $12,000 loss is a real cost of ownership, even though you do not write a check for it.
Depreciation is usually the largest single cost of driving a new car, larger than fuel or insurance. A used car depreciates more slowly in percentage terms but still loses value. A car you buy for $10,000 might be worth $7,000 two years later. The way to minimize depreciation cost is to keep the car longer (spread the loss over more miles) or buy a used car that has already taken its biggest depreciation hit.
If you lease instead of buy, you avoid depreciation risk — the leasing company absorbs it. But you pay for that protection through higher monthly payments and mileage limits. Leasing makes sense if you drive predictable miles, want a new car every few years, and do not want to deal with repairs. It does not make sense if you drive more than 12,000 to 15,000 miles per year or want to customize the vehicle.
How to calculate your own cost per mile
To find your actual cost per mile, add up everything you spent on the car in a year: payments, insurance, gas, maintenance, registration, and tires. Then divide by the number of miles you drove.
Example: You own a five-year-old Honda Civic outright. In one year you spent $1,200 on insurance, $150 on registration, $800 on gas, $300 on maintenance and tires, and $0 on payments. That is $2,450 total. You drove 12,000 miles. Your cost per mile is $2,450 ÷ 12,000 = about 20 cents per mile.
Example: You financed a new Toyota Camry for $28,000 at 5 percent interest. Your payment is $530 per month, or $6,360 per year. Insurance is $1,200 per year. Gas is $1,000 per year. Maintenance is $400 per year. Registration is $150 per year. Depreciation (the car loses $4,000 in value that year) is $4,000. Total: $13,110 per year. At 12,000 miles, that is $1.09 per mile.
The second example costs five times more per mile than the first, even though the Camry is a reliable car. The difference is the car payment and depreciation. This is why buying a reliable used car and keeping it for 10 years is usually cheaper than buying new every five years.
Insurance: usually your second-largest expense
Insurance costs vary more than any other driving expense. A 25-year-old with a clean record in a rural area might pay $80 per month. A 19-year-old with an accident on their record in a city might pay $250 per month. A 65-year-old in the suburbs might pay $120 per month. The same car can have wildly different insurance costs depending on who is driving it and where.
The main factors that set your rate are your age, driving record, location, the type of car, and how much coverage you choose. Younger drivers pay more because they have more accidents. Drivers with accidents or tickets on their record pay more. Urban areas have higher rates than rural areas because there are more collisions and theft. Sports cars and luxury cars cost more to insure than sedans. Choosing higher deductibles ($1,000 instead of $500) lowers your premium but means you pay more out of pocket if you have a claim.
The only way to know what insurance will cost you is to get quotes from multiple companies. Rates change every six months, so shopping around every time your policy renews can save you $200 to $500 per year. If your driving record improves or you move to a cheaper area, your rate should drop.
Fuel economy makes a real difference in total cost
A car that gets 30 miles per gallon costs less per mile in fuel than a car that gets 20 miles per gallon. Over 12,000 miles per year, that difference adds up to $400 to $600 per year in fuel alone.
| Miles Per Gallon | Cost Per Mile (at $3.25/gallon) | Annual Fuel Cost (12,000 miles) |
|---|---|---|
| 18 MPG (truck) | 18 cents | $2,167 |
| 25 MPG (sedan) | 13 cents | $1,560 |
| 35 MPG (hybrid) | 9 cents | $1,086 |
| 50 MPG (plug-in hybrid) | 6.5 cents | $780 |
Fuel economy matters more if you drive a lot. If you drive 5,000 miles per year, the difference between a 20 MPG truck and a 35 MPG sedan is only $150 per year. If you drive 20,000 miles per year, it is $600 per year. Over five years, that is $3,000. This is why people who drive long commutes often save money by buying a more efficient car, even if it costs more upfront.
Frequently Asked Questions
Does it cost more to drive an electric car?
Electricity is cheaper than gasoline per mile — usually 3 to 5 cents per mile versus 12 to 15 cents for a gas car. But electric cars cost more upfront, and battery replacement (if needed after the warranty) can be expensive. Over the life of the car, an electric vehicle often costs less per mile, especially if you charge at home on a cheap electricity plan. The math changes if you have to pay for public charging.
What is the cheapest way to reduce my driving costs?
Drive less. Every mile you do not drive saves you fuel, maintenance, and depreciation. If you can combine trips, work from home one day per week, or use public transit for one commute, you cut costs when ready. The second-cheapest option is to buy a reliable used car with good fuel economy and keep it for 10 years instead of trading it in every five.
Should I buy a new car or a used car?
A used car costs less upfront and depreciates more slowly, so the per-mile cost is usually lower. A new car has lower maintenance costs for the first few years and comes with a warranty. If you drive fewer than 10,000 miles per year and keep the car for three years, new might make sense. If you drive more or keep cars longer, used is almost always cheaper per mile.
How much does it cost to own a car if I do not drive it?
You still pay insurance, registration, and depreciation. If you own the car outright, that is $100 to $200 per month in insurance and registration alone. If you have a loan, add your payment. This is why storing a car you do not drive costs money — you are better off selling it or using a car-sharing service when you need a vehicle.
Does regular maintenance really save money?
Yes. A car that gets oil changes every 5,000 miles and has its brakes and filters serviced on schedule costs less to repair than one that is neglected. Preventive maintenance catches small problems before they become expensive ones. A $100 brake inspection might reveal that pads need replacing soon, saving you from a $500 rotor replacement later. Over the life of the car, staying on top of maintenance usually saves $1,000 to $3,000.
