The cheaper car is the one with the lower total cost over your actual ownership period—not necessarily the one with the lower fuel bill. Compare similar vehicles using the same years and miles, then add purchase and financing, energy, insurance, maintenance, repairs, taxes, fees, charging equipment, and resale value.
Use local gasoline and electricity prices and real insurance quotes. Show both total dollars and cost per mile, then test how the result changes if you drive more or less, keep the car longer, pay different energy prices, or sell it for a different amount.
Start with an apples-to-apples comparison
A powertrain comparison is meaningful only when the vehicles serve the same job. A small economy gasoline car and a large premium electric vehicle have different purchase prices, space, equipment, performance, tires, and depreciation patterns. If you compare them anyway, you cannot tell how much of the price difference comes from electricity versus the vehicle itself.
Match the vehicles
Choose candidates in the same practical class and condition:
#1 Best Overall
- WORKS WITH EVERY NON-TESLA EV: Standard J1772 connector plugs straight into Ford, Chevrolet, Hyundai, Kia, Nissan, BMW, Volkswagen, Audi, Rivian, Lucid and every other EV or plug-in hybrid sold with a J1772 port - no adapter needed. Tesla drivers can charge too, using the J1772 adapter that comes with the car. The extra-long 25 ft cable easily reaches across a garage or driveway.
- HARDWIRED - PROFESSIONAL INSTALL: This Level 2 charger is hardwired (not plug-in), so a licensed electrician installs it per National Electrical Code. It delivers up to 48A on a dedicated 60A, 240V circuit - enough to charge most EVs fully overnight. Want more speed? You can set DIP switches 4 and 5 to unlock 50A on a dedicated 70A circuit. Before ordering, check your car's port type and that your electrical panel can support the circuit.
- CONTROL FROM YOUR PHONE: A stronger built-in antenna keeps the charger online even in a garage or basement. Use the free app to start and stop charging, set the charging speed (6-48A), get reminders, and track how much energy and money each charge uses. Requires a 2.4 GHz home WiFi network.
- SAFETY-CERTIFIED & WEATHERPROOF: Independently tested and certified (UL, ETL, FCC, Energy Star). A fully sealed IP66 / NEMA 4 housing stands up to rain, snow, heat and dust indoors or out, and internal steel shielding protects the electronics for years of reliable use.
- GLOW-IN-THE-DARK HOLSTER: The included high-visibility holster glows in the dark so you can find and dock the plug easily at night. Holds the connector securely when not in use.
- Compare new with new or used with used.
- Match body style, passenger and cargo capacity, towing or weather capability, and equipment level.
- Use similar age, mileage, warranty status, and optional equipment when comparing used cars.
- Record the exact trim and battery or engine configuration. Efficiency can vary materially within one model line.
The U.S. Department of Energy and Argonne National Laboratory model several size classes and powertrains for this reason: vehicle class is a cost variable, not a detail to ignore.
Fix the time and mileage assumptions
Pick an ownership horizon and annual mileage that reflect your plan. Five years at 12,000 miles a year is a different financial decision from ten years at 20,000 miles a year. Use the same horizon, annual miles, city/highway mix, and number of trips for both vehicles.
The DOE Alternative Fuels Data Center (AFDC) calculator asks for daily driving, days and weeks driven, highway share, and other trips because driving patterns affect energy use. Write these assumptions at the top of your worksheet so you do not quietly change them for one vehicle.

List every cost category before calculating
A reliable total-cost-of-ownership worksheet has a line for every cash cost and for resale proceeds. Do not let a low electricity bill stand in for the whole analysis.
1. Purchase price, financing, taxes, and fees
Use the transaction price you can actually obtain, not an old sample MSRP. Record the negotiated vehicle price, destination and dealer charges, sales or use tax, title, registration, documentation fees, and any required equipment. Subtract only incentives for which you are eligible.
Financing is a real ownership cost. For each vehicle, record the down payment, amount financed, annual percentage rate, term, total interest, and any loan fees. If you are paying cash, record the purchase amount and state that no loan interest is included. Keep the treatment consistent: a down payment is a timing of payment, while interest and fees are additional cost.
DOE’s incremental purchase-cost methodology compares current-market electric-vehicle costs with comparable internal-combustion models and is reviewed as markets change. That is a useful framework, but your signed quote is the relevant input for your decision.
2. Fuel or electricity
Energy cost is the category most people calculate first, but it is only one component. Calculate it from the vehicle’s efficiency, your miles, and prices you can actually pay.
For a gasoline car:
Annual fuel cost = annual miles ÷ real-world miles per gallon × local gasoline price per gallon.
Use an efficiency estimate that fits your driving, load, weather, and speed. An advertised test value can be a starting point, not a guarantee. Use the same city/highway assumptions for the electric candidate.

Separate home, workplace, and public charging. Home electricity may have a time-of-use rate; workplace charging may be free or priced separately; public stations can charge per kWh, by time, or add session fees. Include charging losses when your efficiency source excludes them or when you make a transparent allowance.
A practical worksheet uses a blended rate:
Blended EV rate = (home kWh × home price + workplace kWh × workplace price + public kWh × public price + applicable fees) ÷ total kWh.
Then multiply that rate by expected annual kWh. If you do not know the mix, create low-, medium-, and high-public-charging cases instead of hiding uncertainty in one number.
3. Insurance
Get quotes for the exact trims, the same driver or household, address, deductibles, liability limits, comprehensive and collision limits, annual mileage, and usage. An EV is not automatically cheaper or more expensive to insure. Repair costs, theft rates, vehicle value, driver history, and insurer underwriting can move the premium in either direction.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteSave the quote date and assumptions. If one insurer will not quote both vehicles, compare equivalent quotes from another insurer rather than mixing coverage levels.
4. Maintenance and repairs
Build a schedule for tires, inspections, fluids, brakes, filters, wiper blades, alignment, and manufacturer services. EVs generally do not need engine-oil changes, but they still need tires, brakes, suspension work, cabin filters, coolant or thermal-system service where specified, and electronic or charging-system repairs.
Use a defined horizon and vehicle-specific service information. General averages are planning estimates, not a promise about your car. Include a repair reserve for out-of-warranty work, and state whether that reserve is an expected average or a conservative budget.
The DOE and Argonne 15-year scenario found vehicle cost to be the largest component for the studied powertrains, with maintenance and repair together second for most of them. That finding applies to their modeled assumptions, not to every driver or model.

5. Taxes, registration, and recurring fees
Record purchase tax, title and registration, annual property or vehicle taxes where applicable, inspection charges, toll-program fees, and any EV-specific road-use or registration fee in your jurisdiction. Keep one-time purchase charges separate from recurring costs so changing the ownership period produces a sensible result.
Rank #3
- WORKS WITH EVERY NON-TESLA EV: Standard J1772 connector plugs straight into Ford, Chevrolet, Hyundai, Kia, Nissan, BMW, Volkswagen, Audi, Rivian, Lucid and every other EV or plug-in hybrid sold with a J1772 port - no adapter needed. Tesla drivers can charge too, using the J1772 adapter that comes with the car.
- PLUG IN, NO HARDWIRING: Level 2 charger delivers up to 40A to fully charge most EVs overnight. Plugs into a 240V, 4-prong NEMA 14-50 outlet (the RV/range type - NOT a dryer outlet) on a dedicated 50A circuit. The extra-long 25 ft cable easily reaches across a garage or driveway. Before ordering, check your car's port type and that you have the right outlet.
- CONTROL & SAVE FROM YOUR PHONE: A stronger built-in antenna keeps the charger online even in a garage or basement. Use the free app to start/stop charging, set speed (6-40A), get reminders, and track energy use and cost. Schedule off-peak overnight charging to cut your electric bill. Requires 2.4 GHz WiFi.
- SAFETY-CERTIFIED & WEATHERPROOF: Independently tested and certified (UL, ETL, FCC, Energy Star). A fully sealed IP66 / NEMA 4 housing stands up to rain, snow, heat and dust indoors or out, and internal steel shielding protects the electronics for years of reliable use.
- GLOW-IN-THE-DARK HOLSTER: The included high-visibility holster glows in the dark so you can find and dock the plug easily at night. Holds the connector securely when not in use.
6. Home charging equipment and installation
Add charging setup only when your intended arrangement requires it. AFDC says an EV includes a Level 1 cordset for a standard 120-volt household outlet. A Level 2 unit can generally charge a fully depleted EV overnight, but it may require a dedicated circuit, panel capacity, permits, wiring, and professional installation.
Separate these costs in the worksheet:
- Charging equipment or wall unit.
- Electrical work, conduit, wiring, breaker, panel upgrade, and labor.
- Permit or inspection fees.
- Utility connection or demand charges, if applicable.
- Any rebate that is actually available to your address and installation date.
Some drivers can use the included Level 1 cord, workplace charging, or an existing compatible outlet and need no Level 2 purchase. Renters or people without a dedicated parking space may face a different charging plan and should not be assigned a home-installation cost they will not incur. Ask the dealer or manufacturer about compatible home Level 2 options, then obtain an installer quote before treating the amount as known.
7. Resale value and depreciation
Resale is a cash benefit that reduces ownership cost. Estimate what each car will be worth at the end of the same period and mileage, then subtract that amount from cumulative cost.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Use comparable age, condition, mileage, battery or warranty status, trim, and market assumptions. Do not assume an EV or gasoline car will retain a fixed percentage forever. Used-market prices, new-car discounts, battery technology, incentives, fuel prices, and local demand can change depreciation.
Use a transparent calculation
For each vehicle, calculate:
Total ownership cost = purchase and financing cost + energy cost + insurance + maintenance + repairs + taxes and fees + charging setup − resale proceeds.
Cost per mile = total ownership cost ÷ total miles driven during the period.
Total dollars answer how much cash the plan consumes. Cost per mile makes plans with different annual mileage easier to compare. Report both; neither replaces the other.

Worked example: how the arithmetic behaves
The following is an illustrative worksheet, not a market quote or a prediction. It shows why a lower energy bill can still leave one car with a higher total cost. Assumptions are five years, 12,000 miles per year, and 60,000 total miles. Purchase-and-financing figures include illustrative taxes and interest; insurance, maintenance, repair, charging, and resale values are hypothetical inputs that must be replaced with your own quotes.
| Five-year item | Illustrative gasoline car | Illustrative electric car |
|---|---|---|
| Purchase, taxes, and financing | $31,500 | $39,500 |
| Fuel or charging energy | $6,750 (32 mpg, $3.60/gallon) | $3,162 (31 kWh/100 miles, $0.17/kWh blended rate) |
| Insurance | $8,000 | $9,000 |
| Maintenance and repairs | $5,500 | $4,000 |
| Home charging equipment and installation | $0 | $1,800 |
| Resale proceeds | −$15,000 | −$18,000 |
| Total ownership cost | $36,750 | $39,462 |
| Cost per mile | $0.61 | $0.66 |
In this particular set of assumptions, the electric car saves $3,588 in energy and $1,500 in maintenance and repairs, but its higher acquisition cost, insurance, and charging installation outweigh those savings. Change the purchase prices, annual miles, electricity rate, insurance quotes, or resale estimates and the ranking can reverse. The purpose of the example is the method, not a general verdict.
What published scenarios can—and cannot—tell you
The DOE and Argonne National Laboratory’s 2021 report modeled a 2025 small SUV over a 15-year scenario. It reported these modeled cost-per-mile results:

| HEV | 44.6 cents | 15-year modeled small-SUV scenario |
| BEV200 | 45.3 cents | 15-year modeled small-SUV scenario |
| BEV300 | 51.8 cents | 15-year modeled scenario; the report attributes the higher result in part to its assumed battery cost |
These are not 2026 market quotes, personal forecasts, or universal EV results. They demonstrate why vehicle cost, financing, energy, insurance, maintenance, repairs, taxes, and resale must be modeled together.
AFDC published 2023 sample annual fuel-cost figures for listed Kia Niro models: $1,100 for the Niro Hybrid, $850 for the Niro PHEV, and $650 each for the Niro Electric and Chevrolet Bolt. Those figures are dated examples, not current prices for your car. A current personalized calculation is more useful.
EPA states 39 kWh per 100 miles as the model-year 2025 median EV energy-consumption figure, using the national-average electricity carbon-emissions factor from eGRID 2023. That is an emissions-tool assumption, not a price estimate and not a substitute for the efficiency of a specific vehicle.
Check incentives against the transaction date
As of the current federal guidance described here, the new, previously owned, and qualified commercial clean-vehicle credits are not available for vehicles acquired after September 30, 2025. A qualifying vehicle acquired on or before that cutoff may potentially qualify when placed in service later, subject to the applicable requirements. The IRS describes acquisition using a binding written contract plus payment.
Do not place a former federal credit in a current estimate merely because a listing or calculator still displays it. Verify whether your contract and payment meet the cutoff and all eligibility rules. Check federal, state, local, utility, and dealer offers separately because amounts, income limits, vehicle rules, funding, and expiration dates vary by location and can change.
Run sensitivity checks before deciding
A single total hides the assumptions that matter most. Duplicate the worksheet and change one variable at a time.
Annual mileage
Test low, expected, and high mileage. Energy and some maintenance costs rise with miles, while purchase, financing, and installation costs are largely fixed. Higher mileage often makes an energy-efficiency advantage more valuable, but the result still depends on the purchase-price gap and resale.
Ownership period
Compare a short holding period with a longer one. A short period gives depreciation and transaction costs more weight; a long period spreads them over more miles and exposes the vehicles to more repairs, energy-price changes, and resale uncertainty.
Energy prices and charging mix
Use at least a low and high gasoline price and a low and high electricity rate. For an EV, test the share of public charging separately. A driver who charges mostly at home may have a very different result from one who relies on paid fast charging.

Resale value
Use optimistic, middle, and pessimistic end values. Depreciation is often one of the largest differences between otherwise similar ownership plans, and it is difficult to know precisely years in advance.
Break-even mileage
If the electric car costs more upfront, calculate the mileage at which its operating savings recover that difference:
Break-even miles = additional upfront and setup cost ÷ (gasoline cost per mile − EV charging cost per mile).
Use the full model for a final decision because insurance, maintenance, financing, taxes, and resale also vary. The formula is a quick diagnostic, not a replacement for total cost of ownership.
Use calculators without surrendering judgment
DOE AFDC Vehicle Cost Calculator
The AFDC calculator supports custom vehicle entries, purchase price, vehicle efficiency, driving pattern, state electricity price, and other inputs. DOE warns that prices and specifications change frequently and that not all information has been verified. Confirm current details with the manufacturer, dealer, utility, and insurer before signing a contract.

Use the report to understand comprehensive cost categories and how vehicle class and assumptions change results. Treat its modeled figures as scenarios, not a personalized forecast.

Common mistakes and fixes
- Comparing unlike cars: Match class, size, capability, condition, and equipment before comparing powertrains.
- Using a national average fuel price: Replace it with your local price and test a range.
- Assuming the EPA number is your bill: Adjust for your driving pattern and charging losses or fees where supported by data.
- Counting only home electricity: Include workplace and public charging in the expected mix.
- Ignoring financing: Add interest and loan fees, or clearly state a cash purchase.
- Assuming insurance is lower for an EV: Quote both cars with identical coverage.
- Leaving out resale: Estimate end value at the same age and mileage and subtract it from cost.
- Assigning every EV a Level 2 installation: Price the setup you actually need; some drivers can use Level 1 or existing charging.
- Using an expired incentive: Check acquisition date, eligibility, location, and funding before subtracting it.
- Treating a modeled report as a guarantee: Replace generic assumptions with your quotes and perform sensitivity checks.
Make the decision from the range, not one attractive number
After the sensitivity runs, identify which assumptions change the winner. If one vehicle remains cheaper under realistic low, expected, and high cases, the decision is financially robust. If the ranges overlap, choose based on non-financial priorities such as charging convenience, road-trip needs, performance, space, emissions goals, and tolerance for price uncertainty—but keep the cost worksheet available so you know what those preferences cost.
