Short answer: An electric car usually costs less to fuel than a comparable gasoline car when gasoline prices rise, provided your electricity rate and the vehicles’ efficiency stay the same. That is an energy-cost result, not a guarantee that an EV will cost less to buy and own. Purchase price, financing, depreciation, insurance, maintenance, repairs, charging access and installation can outweigh fuel savings for some drivers.
The only reliable way to decide is to compare specific vehicles with your annual mileage, local pump price, electricity tariff and expected ownership period. The figures below show how to do that for the United States; prices and incentives elsewhere require local data.

What high oil prices change—and what they do not
Crude oil is an input to gasoline markets, but a change in oil prices does not translate one-for-one into the price displayed at every fuel station. Taxes, refining, distribution and local competition also matter. Use the gasoline price you actually pay rather than trying to infer it from a crude-oil quote.
Electricity is not completely insulated from energy markets either. The U.S. Energy Information Administration says electricity prices reflect generation, grid construction and maintenance, transmission and distribution, fuel, weather and regulation. Some utilities also use time-of-day rates. Your marginal charging rate can therefore differ substantially from a national average.

Higher gasoline prices improve an EV’s per-mile energy advantage when the electricity rate and vehicle efficiencies are held fixed. They do not, by themselves, establish a lower total cost of ownership. A fair decision separates two questions:
- Running cost: How much will energy cost for each mile?
- Ownership cost: What will the vehicle cost after purchase, financing, depreciation, insurance, maintenance, repairs, charging equipment and incentives?
U.S. electricity prices vary widely
EIA’s 2025 annual averages, based on Electric Power Monthly tables published in February 2026 and marked preliminary, illustrate why a national average is only a starting point.
| Customer class or measure | 2025 average electricity price |
|---|---|
| U.S. residential | 17.30 cents per kWh |
| U.S. commercial | 13.41 cents per kWh |
| U.S. industrial | 8.62 cents per kWh |
| U.S. transportation | 13.83 cents per kWh |
| All U.S. customer types | 13.63 cents per kWh |
| Lowest state all-customer average: North Dakota | 8.20 cents per kWh |
| Highest state all-customer average: Hawaii | 35.72 cents per kWh |
These are annual averages, not a quote for your next charge. A residential customer may pay a different marginal rate after fixed charges, tier thresholds or time-of-use adjustments. Check the tariff that applies to the outlet where you will charge.

The two energy-cost formulas
Gasoline vehicle
Use either the vehicle’s real-world fuel economy or its EPA combined rating, and be consistent when comparing cars:
Annual gasoline cost = annual miles ÷ miles per gallon × gasoline price per gallon
For a distance-based comparison:
Gasoline cost per 100 miles = 100 ÷ MPG × gasoline price per gallon
Electric vehicle
Use the EV’s consumption in kilowatt-hours per 100 miles and your effective electricity price:

Worked example: a transparent high-gasoline-price scenario
The following is an illustration, not a forecast or a claim about today’s prices. It holds the same assumptions constant while changing only the gasoline price:

- Gasoline car rated at 25 MPG combined.
- EV consumption of 39 kWh per 100 miles, the EPA model-year 2025 median combined city/highway assumption.
- Residential electricity at 17.30 cents per kWh, EIA’s 2025 U.S. average.
- Scenario gasoline prices of $3, $4 and $5 per gallon.
| Scenario gasoline price | Gasoline cost per 100 miles | EV cost per 100 miles | Gasoline annual cost at 12,000 miles | EV annual cost at 12,000 miles |
|---|---|---|---|---|
| $3 per gallon (scenario) | $12.00 | $6.75 | $1,440 | $810 |
| $4 per gallon (scenario) | $16.00 | $6.75 | $1,920 | $810 |
| $5 per gallon (scenario) | $20.00 | $6.75 | $2,400 | $810 |
Under these assumptions, the EV’s energy advantage widens as gasoline becomes more expensive. At $5 per gallon, the modeled difference is $1,590 per year. That is not a predicted saving for any particular driver: a different EV, MPG rating, electricity tariff, mileage, weather or charging mix changes the result, and the table excludes every non-energy ownership cost.
How your electricity rate changes the result
Keeping the 39-kWh-per-100-mile EV assumption, the energy cost is about $3.20 per 100 miles at North Dakota’s 8.20-cent all-customer average, $6.75 at the 17.30-cent residential U.S. average, and $13.93 at Hawaii’s 35.72-cent all-customer average. The comparison uses statewide annual averages, not individual residential bills.
Public charging can be more expensive than a home tariff. EPA says home or workplace Level 1 and Level 2 charging is usually cheaper than DC fast charging. If most of your miles come from paid fast chargers, use those session prices in the EV calculation instead of assuming the household rate applies to every mile.
Build a blended charging rate
Many drivers use more than one charging source. Calculate a weighted effective rate rather than applying the cheapest rate to every mile:
Do these 3 things before closing this tab:

Estimate the share of energy supplied at home, at work, at public AC stations and at DC fast chargers. Include per-session, parking or connection fees in the relevant category. If a workplace charger is free today, model that as a current assumption and test what happens if the benefit disappears. For time-of-use plans, use the rate during the hours your car actually charges, not simply the plan’s lowest advertised rate.
Charging access is part of the price
Level 1 at home
Level 1 uses a 120-volt outlet. EPA’s home-charging guide estimates roughly 3–5 miles of range per hour. It can suit a short daily commute, a plug-in hybrid or an EV that sits overnight for many hours. Some vehicles include the required cord, but verify what is supplied before budgeting.
Level 2 at home
Level 2 uses 240 volts and delivers about 25–40 miles of range per hour in EPA’s guide, with actual speed varying by amperage, vehicle and charger. It is more useful for long commutes, multiple vehicles or drivers who need a faster overnight refill.
EPA estimates Level 2 equipment at $400–$1,000 depending on features. Installation is estimated at $300–$2,000 depending on the home’s setup. These are planning ranges, not installer quotes. Cost can change with amperage, the distance from the electrical panel, wall or trench work, outdoor placement and required electrical upgrades.
Public AC and DC fast charging
Level 2 public stations can fill gaps when home charging is unavailable. DC fast charging is primarily offered at public stations and is useful on longer trips, but its price structure is often higher than charging at home or work. Include the share of your annual miles charged publicly, session fees and any idle or parking charges.
Electrical and safety checks
For a new Level 2 circuit, EPA advises professional installation. Before buying equipment, verify:
- Charger certification and the connector that matches your vehicle.
- Cable length and whether the unit is rated for outdoor weather.
- Available electrical capacity, breaker size and panel condition.
- Whether a permit, load calculation or service upgrade is required.
- Current federal, state, local or utility incentives, which must be confirmed for your address and installation date.
When an EV can still cost more overall
Purchase price and financing
Sticker prices differ by model, trim and market. The Department of Energy maintains a methodology for estimating incremental purchase costs of EV types compared with comparable internal-combustion vehicles and lists a January 2025 report. It periodically reviews technology and market changes rather than asserting one universal EV premium. Compare the actual transaction prices and financing terms for the two vehicles you would buy.

Depreciation is often the largest ownership expense after purchase. Estimate the expected resale value over your planned holding period instead of comparing only monthly fuel bills. A vehicle with lower energy cost can still lose more value, or a higher-priced model can retain more value; neither outcome is universal.

Insurance
Obtain quotes for the exact trims and drivers. Repair costs, replacement-part prices, location, driving history and coverage limits can move premiums independently of fuel type.
Maintenance and repairs
EVs generally have fewer engine-related service items, but they still require tires, brakes, suspension work, fluids specified by the manufacturer and eventual repairs. Gasoline cars have engine oil and other powertrain maintenance. Use the manufacturer’s schedule and local labor rates rather than assuming a fixed percentage saving.
Existing-car decisions
If you already own a gasoline car, compare the cost of keeping it with the incremental cost of replacing it. Do not count the past purchase price as a new switching expense. Include remaining loan balance, expected repairs, resale or trade-in value, insurance changes and the cost of installing a charger.
Turn energy savings into a payback estimate
First calculate the EV’s additional upfront cost: purchase-price difference, financing charges attributable to that difference and any charger or electrical work. Then subtract verified incentives. Divide the remaining amount by the expected annual difference in energy, maintenance and repair costs. The result is a simple payback estimate in years:
Payback period = net additional upfront cost ÷ annual operating-cost savings
This is only a screening tool. If the annual operating difference is small or negative, there is no energy payback. A more realistic comparison discounts future cash flows, includes resale value at the end of the holding period and tests several gasoline and electricity-price scenarios. A high gasoline price shortens payback only while the EV’s other assumptions remain unchanged.
A step-by-step comparison you can reproduce
- Choose comparable vehicles. Match body size, passenger and cargo needs, performance and expected use. Compare the EV with the gasoline model you would realistically purchase, not an unrelated luxury or economy car.
- Record efficiency. Enter the gasoline model’s combined MPG and the EV’s kWh per 100 miles. Note whether the figures are EPA ratings, manufacturer figures or your own logged results.
- Measure your driving. Use annual miles, commute length, road-trip frequency, climate and the proportion of city, highway and towing use.
- Price energy locally. Enter the pump price you face and the marginal household electricity rate. Add workplace, public AC and DC fast-charging prices according to how often you use them.
- Calculate annual energy cost. Apply the formulas above, then test low, base and high gasoline-price scenarios. Label scenarios as hypothetical rather than current market facts.
- Price charging infrastructure. Determine whether Level 1 meets your routine. If not, obtain an electrician’s quote for Level 2 and subtract only incentives you have verified for your location.
- Add ownership costs. Compare purchase price, financing interest, depreciation, insurance, maintenance and repairs over the same ownership period.
- Check the break-even point. Divide the EV’s additional upfront and installation cost by the expected annual energy and maintenance difference. Recalculate if prices, mileage or resale assumptions change.
- Run the result through the DOE AFDC Vehicle Cost Calculator. Enter the vehicle, purchase price, driving pattern, fuel economy, electricity efficiency and state. Treat its output as an estimate: DOE notes that vehicle prices and specifications change frequently and that not all data have been verified by DOE or its site manager.
Common mistakes that reverse the conclusion
- Using a national electricity average as your bill. State, utility territory, customer class, tier and time of day can materially change the marginal rate.
- Assuming every EV gets 39 kWh per 100 miles. That is EPA’s model-year 2025 median comparison input, not an efficiency rating for every EV. Size, tires, speed, temperature and driving style matter.
- Counting only the cheapest charging. If you rely on DC fast charging, model its actual price and frequency.
- Comparing unlike vehicles. A small, efficient gasoline sedan and a large electric SUV do not answer the question of replacing one with the other.
- Ignoring winter and highway effects. Cold weather, heating, high speeds, hills and payload can increase energy use for either powertrain.
- Treating incentives as permanent. Verify eligibility, expiration dates, income limits, vehicle qualification and whether the benefit is a tax credit, rebate or utility discount.
- Confusing operating savings with payback. A lower annual energy bill does not automatically recover a purchase-price or charger-installation difference during your ownership period.
- Ignoring time value of money. Financing rates and the timing of fuel savings affect the result; compare cash flows over the same years.
- Forgetting fixed utility charges. Do not assign an entire monthly electric bill to the car. Use the incremental or marginal cost of the additional charging energy, while separately listing any charger-specific demand or connection fees.
Which drivers are most likely to benefit from an EV during expensive gasoline periods?
- Drivers with high annual mileage and a predictable place to charge overnight.
- Households whose electricity tariff is relatively low or offers inexpensive off-peak hours.
- People replacing an older, inefficient gasoline vehicle with a similarly sized EV.
- Drivers who can use Level 1 or Level 2 at home or work instead of frequent DC fast charging.
- Owners who keep the vehicle long enough for recurring energy savings to matter.
The case is less certain for low-mileage drivers, apartment residents without reliable charging, households facing costly panel upgrades, or buyers comparing a high-priced EV with a much cheaper used gasoline car. In those situations, access, financing and depreciation can dominate the energy calculation.

Frequently Asked Questions
Does a higher gasoline price always make an EV cheaper to own?
No. It generally lowers an EV’s energy cost relative to gasoline when electricity rates and efficiency stay fixed, but purchase price, financing, depreciation, insurance, charging equipment, maintenance and repairs determine total ownership cost.
How do I calculate fuel cost for a gasoline car?
Divide annual miles by the car’s combined MPG and multiply by your actual gasoline price per gallon. For 100 miles, use 100 divided by MPG, multiplied by the gallon price.
How do I calculate an EV’s charging cost?
Multiply annual miles by the EV’s kWh per mile and by the effective electricity rate. For 100 miles, multiply kWh per 100 miles by the applicable rate, including relevant charging fees and losses.
Is 39 kWh per 100 miles the efficiency of every EV?
No. It is EPA’s model-year 2025 median combined city/highway comparison assumption. Individual vehicles vary with size, tires, speed, temperature, terrain and driving style.
Can I charge an EV with a regular household outlet?
Often, yes. EPA’s Level 1 guide estimates about 3–5 miles of range per hour from a 120-volt outlet. It may work for short commutes or long overnight parking, while longer commutes may justify Level 2.
What does a home Level 2 charger cost?
EPA estimates equipment at $400–$1,000 and installation at $300–$2,000, depending on features, amperage, panel capacity, distance, location and required upgrades. These are planning ranges, not quotes.
Is public fast charging cheaper than gasoline?
It depends on the station’s price and your vehicle’s efficiency. Home or workplace Level 1 and Level 2 charging is usually cheaper than DC fast charging, so model your actual charging mix rather than assuming a home rate.

What calculator can compare a gasoline car and an EV?
The DOE Alternative Fuels Data Center Vehicle Cost Calculator lets you enter vehicle, purchase-price, driving, efficiency, electricity and state inputs. Treat its result as an estimate because prices and specifications change and not all data are verified by DOE or its site manager.
The Bottom Line
When gasoline is expensive, a comparable EV usually has the lower energy cost per mile, especially with home or workplace charging. That advantage is not the same as a guaranteed ownership saving. Use your actual pump price, marginal electricity tariff, charging mix, mileage, vehicle prices, financing, depreciation, insurance, maintenance and installation costs. Compare the resulting cash flows over the years you expect to keep the car, and test more than one gasoline-price scenario.
