What an SUV Actually Costs to Fill Up and Drive
How much it costs to fuel an SUV depends on the model, the gas price where you live, and how you drive
An SUV typically costs between $50 and $100 to fill the tank, depending on tank size and current gas prices. Most SUVs hold between 18 and 28 gallons. At a national average gas price, a full tank for a mid-size SUV runs roughly $70 to $85. Larger SUVs and those with bigger engines cost more; smaller crossovers cost less. The price you actually pay shifts with gas prices in your area, which can swing 50 cents or more per gallon between states and even between gas stations a few miles apart.
The real cost to drive an SUV is measured in miles per gallon (MPG). Most SUVs get between 18 and 28 MPG on the highway, and 15 to 22 MPG in the city. That means a 300-mile trip might cost $35 to $50 in fuel alone. If you drive 12,000 miles a year—close to the national average—you will spend roughly $1,500 to $2,200 on gas, assuming a national average price of around $3 per gallon. Your actual number depends on your local gas price, how much city versus highway driving you do, and the specific model you own.
Key Takeaways
- A full tank for most SUVs costs $50 to $100, with the exact amount depending on tank size and your local gas price.
- SUVs typically get 15 to 28 miles per gallon depending on driving conditions and the model, which directly affects your yearly fuel budget.
- Annual fuel costs for an SUV driven 12,000 miles range from roughly $1,500 to $2,200 at average gas prices, but vary by region and driving habits.
- Larger engines, towing, and city driving all increase fuel consumption and push costs higher than the baseline estimate.
- Hybrid and electric SUVs cost significantly less to fuel, though they have higher upfront purchase prices.
What affects how much an SUV costs to drive
Engine size is the biggest factor. A V6 engine uses more fuel than a four-cylinder, and a V8 uses more still. A V8 SUV might get 16 to 20 MPG, while a four-cylinder crossover might get 26 to 32 MPG. The difference adds up: driving 12,000 miles per year in a V8 SUV versus a four-cylinder could cost you $400 to $600 more annually in fuel.
How you drive matters just as much as what you drive. Highway driving is more efficient than city driving because you are not stopping and starting. Aggressive acceleration, speeding, and carrying extra weight all reduce MPG. Towing a trailer can cut fuel economy by 20 to 30 percent. If you tow regularly, budget for noticeably higher fuel costs than the EPA estimate for your vehicle.
Tire pressure and maintenance also shift the number. Under-inflated tires increase rolling resistance and lower MPG. Keeping tires at the manufacturer's recommended pressure and staying current on oil changes can preserve fuel economy. A poorly maintained engine burns more fuel to do the same work.
Comparing fuel costs across SUV types
| SUV Type | Typical MPG Range | Annual Fuel Cost (12,000 miles) |
|---|---|---|
| Small crossover (four-cylinder) | 26–32 MPG | $1,125–$1,385 |
| Mid-size SUV (V6) | 18–24 MPG | $1,500–$2,000 |
| Large SUV (V8) | 16–20 MPG | $1,800–$2,250 |
| Hybrid SUV | 28–35 MPG | $1,030–$1,285 |
| Electric SUV | N/A (electricity) | $400–$600 |
These estimates assume a national average gas price of around $3 per gallon and electricity at $0.14 per kilowatt-hour. Your actual costs will be higher or lower depending on prices in your area. Electric SUVs cost far less to fuel but require access to charging and have a higher purchase price upfront. Hybrid SUVs split the difference: they cost more to buy but use significantly less fuel than traditional gas SUVs.
How to estimate your own SUV fuel costs
Start with your vehicle's EPA rating. You can find it on the window sticker when you buy, in your owner's manual, or on fueleconomy.gov. The EPA lists both city and highway MPG. If you drive mostly highway, use the highway number; if you drive mostly city, use the city number. Most people drive a mix, so averaging the two gives a reasonable estimate.
Next, divide your annual miles by the MPG. If you drive 12,000 miles per year and your SUV gets 22 MPG, you will use about 545 gallons per year. Multiply that by your local gas price. If gas costs $3.20 per gallon where you live, your annual fuel cost is roughly $1,745. Check your local gas prices on GasBuddy or at your regular station to use a realistic number instead of a national average.
Keep in mind that real-world MPG often runs 10 to 20 percent lower than the EPA estimate, especially in city driving. If the EPA says 24 MPG, budget for 20 to 22 MPG in actual use. This gives you a buffer and a more honest picture of what you will actually spend.
Ways to lower fuel costs in an SUV
Keep your tires properly inflated. Check the pressure monthly and before long trips. Under-inflated tires can reduce fuel economy by up to 3 percent per PSI below the recommended level. The correct pressure is listed on a sticker inside the driver's door, not on the tire itself.
Reduce unnecessary weight. Remove roof racks, cargo carriers, and items from the trunk that you do not regularly use. Every 100 pounds of extra weight reduces fuel economy by roughly 1 to 2 percent. If you tow, unhitch the trailer when you are not using it.
Drive smoothly. Accelerate gradually, maintain steady speeds, and avoid idling. Aggressive driving can lower fuel economy by 15 to 30 percent compared to calm, steady driving. On the highway, driving 55 MPH instead of 75 MPH can improve fuel economy by 10 to 15 percent.
Keep up with maintenance. Replace air filters on schedule, use the oil grade recommended in your manual, and address engine problems promptly. A well-maintained engine runs more efficiently and uses less fuel.
Hybrid and electric SUVs as a fuel cost alternative
Hybrid SUVs use a gas engine and an electric motor together. They recharge the battery while you drive and brake, so you do not plug them in. Hybrid SUVs typically get 28 to 35 MPG, cutting fuel costs roughly in half compared to a traditional V6 SUV. The trade-off is a higher purchase price—usually $3,000 to $8,000 more than the gas version of the same model.
Electric SUVs run entirely on battery power and cost far less to fuel. Charging at home typically costs $0.03 to $0.05 per mile, compared to $0.12 to $0.15 per mile for a gas SUV. Over 12,000 miles per year, an electric SUV might cost $400 to $600 in electricity versus $1,500 to $2,200 in gas. The upfront cost is higher, but the fuel savings add up over time. You also need reliable access to charging—either at home or at public stations near your regular routes.
Frequently Asked Questions
How often do I need to fill up an SUV?
It depends on your tank size and driving habits. Most SUVs hold 18 to 28 gallons and get 18 to 28 MPG, so a full tank takes you 300 to 500 miles. If you drive 12,000 miles per year, you will fill up roughly once a week. Highway driving stretches that interval; city driving shortens it.
Is a hybrid SUV worth the extra cost?
A hybrid costs $3,000 to $8,000 more upfront but saves roughly $700 to $1,000 per year in fuel. That payback period is typically five to eight years. If you plan to keep the vehicle that long and drive regularly, a hybrid often makes financial sense. If you trade vehicles every three years, the fuel savings may not offset the higher purchase price.
Why does my SUV get worse gas mileage than the EPA estimate?
Real-world driving is less efficient than EPA test conditions. City traffic, cold weather, short trips, and aggressive driving all lower MPG. Towing, roof racks, and under-inflated tires also reduce fuel economy. Most drivers see 10 to 20 percent lower MPG than the EPA rating in actual use.
Does premium gas improve fuel economy in an SUV?
Only if your SUV requires it. Check your owner's manual or the fuel door for the minimum octane rating. Most SUVs run fine on regular 87-octane gas. Using premium when regular is recommended does not improve MPG or performance and wastes money. If your manual says "premium recommended" (not required), regular gas is safe to use.
What is the cheapest SUV to fuel?
Small crossovers with four-cylinder engines cost the least to fuel, typically $1,100 to $1,400 per year. Hybrid SUVs cost $1,000 to $1,300 per year. Electric SUVs cost the least overall at $400 to $600 per year, though they require a higher purchase price and access to charging.
