Average MPG by Vehicle Type (EPA Combined)
Fuel economy varies significantly by vehicle class. These are typical EPA combined MPG ratings — a blend of city and highway driving. Real-world results usually run 10-20% lower, especially with highway speeds above 65 mph, heavy loads, or stop-and-go traffic.
| Vehicle Type | Typical MPG | Fuel Cost per Mile* | Annual Fuel Cost* |
|---|---|---|---|
| Pickup truck | 18 MPG | $0.19/mile | ~$2,625 |
| Large SUV | 20 MPG | $0.18/mile | ~$2,363 |
| Midsize SUV | 26 MPG | $0.13/mile | ~$1,817 |
| Sedan / compact | 32 MPG | $0.11/mile | ~$1,477 |
| Hybrid (Prius-class) | 52 MPG | $0.07/mile | ~$909 |
| Electric vehicle | 130 MPGe | ~$0.03/mile | ~$364 |

SUV vs Sedan: How Much More Does an SUV Cost in Fuel?
Choosing between an SUV and a sedan is one of the most common vehicle comparison decisions. At 13,500 miles per year and $3.50/gallon, a 20 MPG large SUV costs about $886 more per year in fuel than a 32 MPG sedan. Over a 5-year ownership period, that's roughly $4,400 — before counting higher purchase price and insurance.
Use the calculator above to compare your two candidate vehicles: enter the same distance and gas price, then check the annual savings between the midsize SUV (26 MPG) and sedan (32 MPG) presets to see the real dollar difference.
Hybrids change the math. A 52 MPG hybrid saves about $568/year vs a 28 MPG car — and the gap grows with annual mileage. If you drive 20,000+ miles per year, fuel efficiency should be a top purchase criterion.
Annual Fuel Cost & Gas Budget Planning
The US average driver covers 13,500 miles per year. Fuel is typically 3-5% of gross income for most households — above 8% becomes a significant financial burden worth addressing. To calculate your annual fuel budget: annual fuel cost = (annual miles ÷ MPG) × gas price.
For budgeting, remember that gas prices fluctuate seasonally: they typically rise in spring/summer (driving season) and fall in winter. Budget using a price $0.25-0.50/gallon above today's price to avoid surprises. Recalculate your fuel budget monthly or when gas prices shift by more than 10%.
Fuel Cost Scenarios: When to Use This Calculator
🚐 Planning a Road Trip
Estimate gas cost for a road trip before you leave: enter the total distance, your vehicle's MPG, and current prices along your route. For an 800-mile trip in a 26 MPG SUV at $3.50/gal: (800 ÷ 26) × $3.50 = $107.69 one-way.
🚗 Comparing Cars Before Buying
Use the MPG presets to compare fuel costs across vehicle classes over your annual mileage. The fuel difference between an 18 MPG pickup and a 52 MPG hybrid at 13,500 mi/yr is roughly $1,700/year.
💼 Business Mileage & Reimbursement
Know your cost per mile to evaluate the IRS standard mileage rate ($0.67/mile in 2024, covers all vehicle costs). At 26 MPG and $3.50/gal, your fuel-only cost is $0.13/mile — well under the IRS rate.
📆 Monthly Commute Budget
Estimate your monthly gas spend: enter your daily commute distance × 20-22 working days, your vehicle MPG, and today's price. A 30-mile round trip at 26 MPG and $3.50/gal costs about $80/month.
How to Save on Gas: The Non-Linear MPG Insight
Fuel savings from efficiency are not linear — and most people misunderstand this. At 12,000 miles/year and $3.50/gallon:
- 18 → 28 MPG (pickup to average car): saves $833/year — the biggest jump
- 28 → 50 MPG (average car to hybrid): saves only $188/year
The math: annual savings = annual miles × price × (1/old MPG − 1/new MPG). The huge savings are at the low end of the efficiency scale. If you're replacing an inefficient vehicle, efficiency should be a top priority. If you already own an efficient car, upgrading to a hybrid saves far less than you might expect.
Driving habits also matter: highway speeds above 65 mph cut MPG by 10-15%, aggressive acceleration reduces it by 15-30%, and properly inflated tires add 3-5%. Combined, driving style can cost or save $300-600/year at current prices.
Frequently Asked Questions
How do I calculate fuel cost for a trip?
Fuel cost = (distance ÷ MPG) × gas price per gallon. For a 300-mile trip in a 25 MPG car at $3.50/gallon: (300 ÷ 25) × $3.50 = 12 gallons × $3.50 = $42. For a round trip, double the distance first. Cost per mile = gas price ÷ MPG.
How much does gas cost per mile?
Cost per mile = gas price ÷ MPG. At $3.50/gallon: 32 MPG car = $0.11/mile, 26 MPG SUV = $0.13/mile, 18 MPG pickup = $0.19/mile. The IRS standard mileage rate ($0.67/mile) covers ALL vehicle costs, not just fuel.
How much do I spend on gas per year?
At the US average of 13,500 miles/year: a 28 MPG car costs about $1,687/year at $3.50/gallon; a 20 MPG SUV costs about $2,363/year. Fuel at 3-5% of gross income is manageable; above 8% it's a significant burden.
Is a hybrid worth the extra cost?
For high-mileage drivers (15,000+ miles/year), yes. A hybrid saves $500-900/year in fuel versus a comparable gas car — enough to offset the price premium within 3-5 years. For low-mileage drivers (under 7,000 miles/year), the payback period stretches to 7+ years.
Why is my real-world MPG lower than the sticker?
EPA ratings use controlled lab conditions. Real-world MPG typically runs 10-20% lower due to highway speeds above 65 mph, air conditioning, heavy loads, stop-and-go traffic, cold weather, and driving style. Calculate your actual MPG by dividing miles driven between fill-ups by gallons added.
How does the calculator handle electric vehicles?
EVs are rated in MPGe (miles per gallon equivalent) — typically 130 MPGe. For a more accurate EV cost, multiply your kWh consumption (usually 3-4 miles per kWh) by your electricity rate instead of using gas price.
Fuel is the running-cost half of car ownership — the Auto & Moving guide pairs it with what the car itself costs and what a move costs.
Methodology: All calculations use standard fuel math: fuel needed = distance ÷ MPG; cost = fuel needed × price; cost per mile = price ÷ MPG. MPG figures are typical EPA combined ratings for each vehicle class. Annual estimates assume 13,500 miles/year (US average) and $3.50/gallon — adjust with your own numbers in the calculator.
