The cheaper car is the one with the lower cost over your actual ownership period—not necessarily the one with the lower fuel bill. Compare similar vehicles using the same purchase date, financing assumptions, annual miles, local energy prices, insurance quotes, maintenance and repair estimates, taxes, charging costs, and end-of-period resale value. Then divide the resulting total by miles driven and test how the result changes if your mileage, energy prices, ownership length, or resale estimate changes.
Start with a fair, like-for-like comparison
A total-cost comparison is meaningful only when the vehicles serve the same job. A small gasoline hatchback and a large, highly equipped electric SUV may have very different prices, space, performance, tires, insurance and depreciation before their powertrains are considered. Match the candidates as closely as practical on body style, seating, cargo capacity, capability, safety equipment, trim level and condition.

Match new with new, or used with used
Do not compare a new EV with a three-year-old gasoline car unless your decision really is between those two purchases. For a clean powertrain comparison, use new vehicles at similar equipment levels, or used vehicles with similar age, mileage, warranty status and condition. Record the actual transaction price you could pay, not an old sample MSRP. Dealer discounts, destination charges and market conditions can make the transaction price materially different from the window sticker.
Use the same ownership horizon and driving pattern
Choose a period such as five, eight or 15 years and use it for both vehicles. Set annual miles from your real commute, errands, road trips and seasonal use. If one car is likely to be driven more, that is a legitimate ownership choice, but it should be explicit rather than hidden in the comparison.

Energy use depends on more than an annual-mile figure. Note the share of city and highway driving, number of driving days, weeks driven and occasional long trips. The U.S. Department of Energy’s Alternative Fuels Data Center (AFDC) calculator asks for these kinds of inputs because use patterns change consumption.
Create one input sheet before calculating
| Input | Gasoline car | Electric car | How to establish it |
|---|---|---|---|
| Purchase price | Actual negotiated price plus required charges | Actual negotiated price plus required charges | Written dealer or private-party quote |
| Financing | Amount financed, APR and term | Amount financed, APR and term | Loan offer for each vehicle; include down payment |
| Taxes and registration | Local sales/use tax, title and registration | Local sales/use tax, title and registration | State and local motor-vehicle authority or dealer worksheet |
| Efficiency | Expected miles per gallon | Expected kilowatt-hours per mile | Vehicle specification, then adjust for your driving and weather |
| Energy price | Local gasoline price | Home, workplace and public charging prices | Your utility tariff, charging receipts and local fuel prices |
| Insurance | Quote for your driver and coverage | Quote for your driver and coverage | Quotes using identical limits and deductibles |
| Maintenance and repairs | Scheduled service plus a repair reserve | Scheduled service plus a repair reserve | Manufacturer schedule, warranty terms and independent estimates |
| Charging setup | Usually none beyond normal household costs | Equipment, electrical work and installation if required | Electrician and utility estimates for your home |
| Resale value | Estimated value at the end of the horizon | Estimated value at the end of the horizon | Several current used-listing or valuation references |
Calculate acquisition and financing cost first
Purchase and financing often dominate the early years of ownership. For each candidate, record:
- Vehicle transaction price, including destination or documentation charges that you will actually pay.
- Down payment and the amount financed.
- Annual percentage rate and loan term.
- Total interest over the loan, not only the monthly payment.
- Sales or use tax, title, registration, inspection and other mandatory fees.
- Any incentive for which you are eligible and can document.
A simple ownership worksheet can use acquisition cost = transaction price + taxes and fees − eligible incentive. If you finance, add the interest paid during the ownership period. Do not add the entire loan principal a second time: the principal is already represented by the vehicle price, while interest is the incremental financing cost.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsHandle incentives by eligibility and date
Federal clean-vehicle guidance from the Internal Revenue Service says 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, provided all applicable requirements are met. The IRS describes acquisition using a binding written contract plus payment.
Do not subtract a former federal credit from a current estimate merely because a model used to qualify. Check whether your transaction date, vehicle, buyer, income, dealer process and other requirements fit the rule. Separately check state, local, utility and dealer programs; their amounts, funding and deadlines vary by location and can change. Put each incentive in its own line with a source, expiration date and eligibility note so that a withdrawn offer cannot silently distort the result.
Model gasoline and electricity costs locally
Energy savings are important, but they are only one line in total cost. Use the efficiency of the exact vehicles and the prices you can actually pay.

For a gasoline vehicle, estimate annual fuel cost with:
annual gallons = annual miles ÷ expected real-world mpgannual gasoline cost = annual gallons × local gasoline price

Use a realistic mpg assumption rather than treating a laboratory rating as a promise. If your driving includes winter conditions, roof cargo, towing, heavy traffic or high speeds, create a higher-consumption case. Apply the same annual miles and driving horizon used for the EV.
Electricity calculation
For an EV, convert efficiency to energy used:
annual kWh = annual miles × kWh per mileannual charging cost = (home kWh × home rate) + (workplace kWh × workplace rate) + (public kWh × public rate) + applicable session or parking fees
Vehicle specifications may be expressed as kilowatt-hours per 100 miles. Convert them by dividing by 100 to obtain kWh per mile. If a specification or calculator already accounts for charging losses, do not add another blanket loss factor. If it reports only battery energy and your meter records more, use a transparent assumption for the difference and label it.

Separate your charging mix. A driver with a garage and an inexpensive overnight tariff may pay very differently from a driver who relies on paid fast charging. Include workplace charging only if access is dependable, and include public charging fees, parking charges or idle fees when they are part of your normal use. If a utility has time-of-use rates, model the hours in which you can realistically charge rather than the cheapest rate on paper.
What published examples can—and cannot—tell you
AFDC published 2023 sample annual fuel-cost estimates for the vehicles in one comparison: $1,100 for the listed Kia Niro Hybrid, $850 for the Niro Plug-in Hybrid, and $650 for the Niro Electric and Chevrolet Bolt. Those are dated examples, not current prices and not forecasts for every driver. Use a current personalized calculation instead of copying them into a 2026 budget.
The Environmental Protection Agency states a 2025 median EV energy consumption of 39 kWh per 100 miles for an emissions-tool assumption using the national-average electricity emissions factor from eGRID 2023. That figure is useful context for emissions analysis; it is not a substitute for the efficiency of your chosen EV and it is not a monetary cost estimate.
Include insurance, maintenance, repairs, taxes and fees
Insurance requires real quotes
Obtain quotes for both vehicles using the same driver, address, annual mileage, liability limits, comprehensive and collision limits, deductibles and optional coverage. An EV is not automatically cheaper or more expensive to insure. Vehicle replacement cost, parts availability, claims history, repair procedures, theft risk and your own profile can move the premium in either direction.
Enter the annual premium for each year of the ownership horizon, or state a documented escalation assumption. A single introductory quote is not a guarantee of future renewal pricing. If you change vehicles, re-quote rather than carrying the old premium across.

Maintenance and repairs are separate lines
List scheduled maintenance by time or mileage: inspections, tires, brakes, fluids, filters, alignment and other manufacturer requirements. EVs generally have no engine oil service, but they still need tires, brake components, suspension work, cabin filters, coolant-related service where specified and other repairs. Gasoline cars have engine, exhaust and transmission systems that may require additional service. Neither general reputation nor a single average guarantees your individual bill.
Use the warranty period and coverage limits to decide which repairs are your responsibility. Create a repair reserve for the years outside warranty, and make the reserve explicit rather than hiding it in a vague “miscellaneous” percentage. If a data source provides only a fleet average, identify it as an estimate and test a low and high case.
Taxes, registration and usage charges
Some jurisdictions charge different registration or road-use fees by powertrain, weight or value. Include one-time title and registration costs and recurring renewal fees. If your state or city applies an EV-specific fee, place it beside the gasoline vehicle’s comparable recurring charges. Do not assume a tax difference exists without checking the rules where the vehicle will be registered.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Price the EV charging setup you actually need
AFDC says EVs come with a Level 1 cordset for a standard 120-volt household outlet. A Level 2 unit can generally charge a fully depleted EV overnight, but the useful choice depends on your daily miles, parking arrangement, electrical service and charging schedule.
Treat charging as three separate costs:
- Hardware: the Level 1 cordset or optional Level 2 home charging equipment.
- Electrical work: a circuit, outlet, panel upgrade, load management or other work required by your installation.
- Installation and permits: electrician labor, inspection and permit charges.
Some buyers need none of these beyond the supplied cord and an existing safe outlet. Others need a dedicated circuit or a service upgrade. Ask the dealer or manufacturer about compatible Level 2 options, then obtain an electrician’s quote for your specific panel, cable route and parking location. Add the one-time cost to the EV’s acquisition section, not to an invented universal charging rate.
If you rent, park on the street or cannot install equipment, model public charging as your normal energy source and include its fees. A charger that is technically faster but rarely accessible does not reduce your actual cost.
Account for depreciation and resale value
Resale value is a cost offset, not an afterthought. For each vehicle, estimate its value at the end of the same ownership horizon and subtract it from the costs you paid:

Use several current references for the same model year, trim, mileage and condition. Adjust for battery warranty remaining on the EV, accident history, market demand, mileage, regional supply and any major repair. If the horizon is 15 years, do not use a three-year residual percentage without explaining the uncertainty; long-term values are especially sensitive to technology, regulation and market conditions.
If you sell before the loan is paid off, compare the expected sale price with the remaining loan balance. Negative equity is a cash-flow risk and should not be mistaken for a low monthly payment.
Build the total-cost worksheet step by step
- Choose the candidates. Record model year, trim, battery or engine configuration, equipment, condition and mileage. Confirm that the vehicles meet the same practical need.
- Set assumptions. Enter ownership years, annual miles, city/highway mix, seasonal use and long-trip frequency. Save a base case before experimenting.
- Enter acquisition data. Add transaction price, taxes, registration, fees, down payment, APR, term and verified incentives. Calculate total interest over the period you expect to keep the vehicle.
- Enter energy inputs. Add mpg and gasoline price for the gas car. Add EV kWh per mile, charging shares, electricity rates, public fees and any supported loss assumption for the EV.
- Enter recurring ownership costs. Add insurance quotes, scheduled maintenance, repair reserves, tire costs, inspections and powertrain-specific registration or road charges.
- Add EV setup costs. Include hardware, electrical work, permits and installation only if your intended charging arrangement requires them.
- Estimate resale. Enter expected proceeds at the end of the same horizon and record the assumptions behind the estimate.
- Calculate totals. Use
total ownership cost = acquisition and financing + energy + insurance + maintenance and repairs + taxes and fees + charging setup − resale value. - Calculate cost per mile. Divide each total by
annual miles × ownership years. Show both the total dollars and dollars per mile; a low per-mile result can still require a larger upfront budget. - Run sensitivity cases. Change one assumption at a time, then run a combined conservative case. Save the outputs so you can see which inputs actually determine the result.
Use calculators as frameworks, not guarantees
The DOE AFDC Vehicle Cost Calculator lets you enter a custom vehicle, purchase price, 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, so confirm current details with the manufacturer or dealer.

What a published 15-year model illustrates
The 2021 DOE/Argonne study modeled a 2025 small SUV over 15 years. It reported these cents-per-mile results:
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →| Modeled powertrain | Modeled cost | How to interpret it |
|---|---|---|
| Hybrid (HEV) | 44.6 cents per mile | Small-SUV, 15-year modeled scenario; not a quote for a specific purchase |
| Battery EV with 200-mile range (BEV200) | 45.3 cents per mile | Same modeled framework; outcome depends on the report’s assumptions |
| Battery EV with 300-mile range (BEV300) | 51.8 cents per mile | Higher modeled cost was attributed in part to the assumed battery cost |
The report found that modeled vehicle cost was the largest 15-year component for the studied powertrains, with maintenance and repair together second for most of them. These figures do not establish that every EV costs more or less than every gasoline car. They show why battery size, vehicle class, purchase price, financing, depreciation and the chosen horizon can outweigh an energy-cost advantage.

Run sensitivity checks that answer your real decision
A single total hides uncertainty. At minimum, create the following cases:
- Low-mileage case: reduce annual miles to reflect remote work, a second household car or limited commuting.
- High-mileage case: increase miles for a long commute or frequent road trips.
- Energy-price case: vary gasoline, home electricity and public charging prices separately rather than moving one blended number.
- Charging-access case: compare mostly-home charging with a public-fast-charging-heavy pattern.
- Ownership-length case: compare an early sale with keeping the vehicle through the loan and warranty period.
- Resale case: use lower and higher end-of-horizon values, especially when the market evidence is thin.
- Insurance and repair case: use your actual quotes, then test a higher premium or repair reserve.
To find an approximate break-even point, hold all non-energy assumptions constant and vary annual miles. The mileage at which cumulative EV savings offset its higher acquisition or charging-setup cost is a property of your inputs, not a universal threshold. If the result flips when one plausible assumption changes slightly, report the decision as sensitive rather than declaring one powertrain definitively cheaper.
Common comparison mistakes and how to correct them
Comparing a fuel bill with a car payment
A monthly gasoline bill versus an EV’s monthly payment is not a total-cost comparison. Put purchase, interest, depreciation, insurance, maintenance, repairs, taxes, fees and energy in the same time period.
Recommended Free Tools
Using one national energy price
Gasoline and electricity prices vary by location and time. Replace a national average with your utility tariff, realistic charging mix and current local fuel price. Keep a dated record so you know when to refresh the model.
Assuming every EV requires a costly charger
Some drivers can use the supplied Level 1 cordset; others need Level 2 equipment or electrical work. Inspect the actual parking and panel situation before adding a setup cost.
Assuming EV insurance or repairs are always lower
Quote both cars for identical coverage and create vehicle-specific maintenance and repair lines. Battery warranty, parts availability and collision repair can change the result.
Subtracting an incentive without checking the transaction date
Verify federal cutoff rules and local program eligibility before reducing the purchase price. Record whether the benefit is a tax credit, point-of-sale discount, rebate or dealer promotion and when the money is received.
Ignoring resale value
A lower operating bill can be overwhelmed by depreciation. Use the same sale date and mileage for both candidates and show the residual assumptions next to the result.
Treating a modeled benchmark as a personal forecast
Published cents-per-mile studies are valuable for understanding cost categories, but their vehicle class, battery cost, financing, energy prices and 15-year assumptions may not match your purchase. Rebuild the calculation with your own quotes.
Make the decision from the result you can verify
Choose the EV when its total cost under your realistic base case is lower and its charging arrangement fits your life, not merely because its energy line is lower. Choose the gasoline car when its purchase price, financing, insurance, resale outlook or refueling convenience produces a lower verified total for your use. If the totals are close, give greater weight to the assumptions you can control—home charging access, annual miles and ownership length—and present the result as a range rather than false precision.
Keep the worksheet, quotes and dates behind your conclusion. Recheck prices, incentives, insurance and resale assumptions before signing, because those inputs can change faster than the vehicle’s advertised efficiency.
