To find out whether an electric car will save you money, compare one specific EV with a similar gasoline car over the same years and miles. Add each vehicle’s purchase or depreciation cost, energy, maintenance, insurance, taxes and fees, and any charging equipment or installation you need. An EV can cost less to run per mile yet still cost more overall if its upfront or ownership costs are higher.
Start with two comparable cars and one ownership period
Choose an EV and a gasoline car that meet the same needs: similar size, equipment, passenger or cargo capacity, and use. Compare them over the same ownership period and annual mileage. Use transaction prices for the vehicles you are actually considering, not a generalized claim about the average EV price premium.
Decide how you will account for the purchase cost before doing the arithmetic. You can compare cash outlay, or compare ownership cost using depreciation and resale value. Apply the same convention to both cars; adding the full purchase price and depreciation together would count the vehicle cost twice.
Use your own figures for financing, resale, insurance, registration, taxes, and fees when available. If you do not yet have a reliable quote, use a clearly labeled estimate or range rather than treating an unknown as zero.

Calculate energy cost per mile
Compare fuel and electricity in the same unit: dollars per mile. Use local gasoline prices, your cars’ actual efficiency, and the electricity price you will pay for each kind of charging.
| Calculation | Formula | What to enter |
|---|---|---|
| Gasoline cost per mile | Local gas price per gallon ÷ gasoline car’s miles per gallon | Your local price and the car’s expected mpg |
| EV electricity cost per mile | EV kWh per mile × effective electricity price per kWh | The EV’s energy use and the rate for the charging you expect to do |
| Annual energy cost | Cost per mile × annual miles driven | Your expected yearly mileage |
| Energy cost over ownership | Annual energy cost × ownership years | Your chosen period and explicit price assumptions |
If the EV’s efficiency is listed in kWh per 100 miles, divide that number by 100 to get kWh per mile. For example, at 39 kWh/100 miles and an assumed electricity price of $0.20/kWh, the arithmetic is 0.39 × $0.20 = $0.078 per mile. That is an illustration, not a forecast for a particular car: replace both inputs with the model’s efficiency under your driving conditions and your effective rate.
Charging location affects the effective rate. Home, workplace, and public charging can have different prices, so estimate the share of your charging that comes from each and calculate a weighted price. Include applicable time-of-use rates or other charges if they affect what you pay. The DOE’s Electric Vehicle Basics describes charging options; the EIA’s electricity price information explains why rates vary by state and other factors.
For context, EIA reports that the 2025 average U.S. residential electricity price was 17.30¢/kWh, based on preliminary Electric Power Monthly data published in February 2026. The all-customer average was 13.63¢/kWh, and state all-customer averages ranged from 8.20¢/kWh in North Dakota to 35.72¢/kWh in Hawaii. These national and state averages are not your personal tariff. Use your utility bill or rate schedule for a personal estimate.

EPA reports a median energy consumption of 39 kWh/100 miles for model-year 2025 EVs using its comparison methodology on a page updated February 18, 2026. That figure is context, not a substitute for the specific car’s efficiency or your driving conditions. The EPA page uses eGRID 2023 for its emissions calculation; that detail does not make the median a personal energy-cost estimate. See EPA’s car-versus-EV comparison.
Add the costs that energy savings do not capture
Estimate each vehicle’s total cost for the chosen period using the same categories. Subtract verified incentives from the applicable vehicle’s costs, and keep unconfirmed incentives out of your main result.
| Cost category | What to include |
|---|---|
| Vehicle cost | Purchase and transaction costs, or depreciation after expected resale value; use one consistent accounting method |
| Financing | Interest and financing charges if you are borrowing, applied consistently to both comparisons |
| Energy | Gasoline or electricity over the ownership period, based on annual miles and stated price assumptions |
| Maintenance and repairs | Model-specific maintenance schedules and realistic repair estimates, where available |
| Insurance | Your quoted premiums for each vehicle |
| Taxes, registration, and fees | Applicable costs for your location and vehicle |
| Charging setup | Home charging equipment and installation only if you need them; account for any relevant utility costs |
| Other owner-specific costs | Any material costs that differ for your use case |
| Verified incentives | Subtract only incentives you have confirmed you and the vehicle qualify for |
All-electric vehicles generally need less maintenance than conventional vehicles because they have no conventional engine and fewer moving parts and fluids to change. Regenerative braking typically reduces brake wear, too. Those are reasons to examine maintenance costs, not a universal dollar saving: use the maintenance schedule and model-specific estimates where available. DOE’s EV basics fact sheet provides this general maintenance context.
You do not necessarily need to buy or install a home charger. If your plan depends on home charging, include equipment and installation costs and obtain local quotes; if you will rely on workplace or public charging, use the prices and availability relevant to those options instead.

Compare total costs and estimate a break-even point
For each vehicle, add its costs over the selected period. Then calculate:
Estimated EV savings = comparable gasoline car’s total cost − EV’s total cost
A positive result means the EV is cheaper under the assumptions you entered; a negative result means it costs more. Show the assumptions alongside the result, especially annual miles, years of ownership, energy prices, purchase or resale figures, and charging mix. There is no universal mileage at which an EV pays for itself: the result depends on the particular cars and the buyer’s costs.
If the EV has a higher upfront cost but lower annual operating costs, estimate the simple operating-cost payback as:

Incremental EV cost ÷ annual operating savings
Here, incremental EV cost is the EV’s extra upfront cost relative to the comparable gasoline car, after any verified incentives you include. Annual operating savings are the gasoline car’s annual operating costs minus the EV’s, using the categories you have chosen to count. This arithmetic is useful only when annual operating savings are positive. If they are zero or negative, there is no fuel-cost payback under those assumptions. The calculation is not a full ownership-cost comparison and does not replace the total-cost calculation above.
Use a calculator, then verify its inputs
The DOE Alternative Fuels Data Center’s Vehicle Cost Calculator is a useful starting point. It uses driving habits to estimate ownership costs and emissions for many vehicle makes and models, and asks for details such as state and driving patterns. Treat its output as an estimate: DOE warns that prices and specifications change frequently, not all data have been verified, and buyers should check with a dealer or manufacturer.
Check current vehicle prices, specifications, insurance quotes, utility rates, charger installation costs, and applicable taxes or fees against your own circumstances. Incentive eligibility depends on the buyer, vehicle, date, and jurisdiction; verify it before including the amount in your main comparison. You can also show an incentive as a separate scenario if eligibility is uncertain. DOE’s purchase-cost methodology is useful context for how purchase-cost comparisons are framed, but it does not establish that a particular buyer qualifies for an incentive.
What published cost-per-mile examples can—and cannot—tell you
DOE’s August 2023 consumer fact sheet gives illustrative costs of 2¢–6¢ per mile for all-electric vehicles and 10¢–15¢ per mile for conventional gasoline or diesel sedans under that document’s assumptions. Those dated general ranges are not current local prices or a guaranteed saving for an individual driver.
