Sizing formula kW = Annual kWh ÷ (Peak Sun Hours × 365 × 0.82)

The average American driver spends $12,182 per year keeping a vehicle on the road — and whether that money goes toward electrons or gasoline increasingly defines two very different financial outcomes over five years. Electric vehicles have crossed a meaningful tipping point in 2026: the upfront price premium has narrowed, federal incentives remain strong, and the per-mile fuel advantage has widened. But “EVs are cheaper” is only the full story if you account for every cost category, not just what you pay at the pump or the charger.

This comparison uses a realistic pairing: a 2026 mid-size EV sedan (think Tesla Model 3, Chevrolet Equinox EV, or Hyundai Ioniq 6) priced at $42,000 versus a comparable 2026 gas sedan (think Honda Accord or Toyota Camry) priced at $32,000. Both are driven 15,000 miles per year — the U.S. average — over five years. Every cost category is itemized so you can see exactly where each vehicle wins, loses, or breaks even.

The short answer is that the EV comes out about $2,700 cheaper over five years after federal tax credits at national average prices — a gap that grows to $5,800 or more in states with stacked incentives and low electricity rates, and narrows to near zero where gas is cheap and electricity is expensive. Your personal number depends on where you live, how you charge, and what you do with the car at the end.

Purchase Price and Federal Tax Credits in 2026

The sticker price gap between EVs and comparable gas vehicles has compressed steadily, but a $10,000 difference remains typical in the mid-size segment. The 2026 EV in this comparison lists at $42,000; the gas equivalent at $32,000. That $10,000 gap is the EV’s biggest hurdle — but the IRS Section 30D clean vehicle credit changes the math at the point of sale.

For 2026, qualifying new EVs receive up to $7,500 in federal tax credit applied directly at purchase, thanks to the Inflation Reduction Act’s direct-pay provision. That brings the effective EV purchase price down to $34,500 — only $2,500 more than the gas car. Income limits apply ($150,000 for single filers, $300,000 for joint filers), and the vehicle must have final assembly in North America with battery components meeting domestic sourcing thresholds. Most mainstream EVs from GM, Ford, Hyundai, and Tesla currently qualify. You can check your specific vehicle’s eligibility and estimate your exact benefit using the IRA rebate calculator before you commit to a purchase.

State-level credits can stack on top of the federal benefit. Colorado offers an additional $5,000 state EV tax credit for new purchases in 2026, effectively bringing a qualifying $42,000 EV to $29,500 out of pocket — nearly $2,500 less than the gas car. California provides rebates up to $4,500 through the Clean Vehicle Rebate Project for income-qualified buyers. Even without state credits, the federal benefit alone closes most of the purchase price gap in the mid-size segment.

Buyers who exceed the income threshold for the new-vehicle credit should consider the IRS Section 25E used clean vehicle credit, which offers up to $4,000 on qualifying used EVs priced under $25,000. The IRS updated eligibility guidance for this credit in early 2026, expanding the pool of qualifying vehicles. Between new and used credit pathways, the federal incentive structure makes the electric vehicle purchase price competitive with gas equivalents for a wide range of households.

5-year cost tally so far — EV: $34,500 | Gas: $32,000 (difference: +$2,500 EV)

Fuel Costs: Electricity vs Gasoline Over Five Years

This is where the EV pulls ahead most consistently. The U.S. Energy Information Administration (EIA) reports the average retail gasoline price in early 2026 at $3.48 per gallon. A gas sedan averaging 32 mpg burns through about 469 gallons annually, costing $1,632 per year or $8,160 over five years.

The EV equivalent — running at 3.5 miles per kWh over 15,000 miles per year — consumes roughly 4,286 kWh annually. At the national average residential electricity rate of $0.163 per kWh (EIA, January 2026), that is $699 per year when charging exclusively at home. Over five years: $3,495. That is a $4,665 fuel saving compared to the gas car before accounting for any public charging costs.

The caveat is public fast charging. If you rely on DC fast charging networks for 30% of your miles, your effective rate climbs to roughly $0.30–$0.40 per kWh at major networks, pushing annual electricity costs closer to $900. Even in that scenario, the EV saves $3,660 in fuel over five years. Drivers who pair their EV with rooftop solar can reduce that fuel cost significantly — the solar EV charging savings calculator estimates annual savings of $800–$1,400 depending on system size and local utility rates.

Electricity prices vary widely by state. Hawaii averages $0.39 per kWh, making EV charging more expensive relative to the national average — though still cheaper per mile than gasoline at 2026 prices. Louisiana averages below $0.10 per kWh, where home EV charging costs drop to under $430 per year. Washington similarly benefits from hydroelectric-driven rates near $0.10 per kWh.

Maintenance, Repairs, and Insurance Over Five Years

Electric vehicles have a fundamental mechanical advantage: fewer moving parts. A gas engine contains roughly 2,000 moving components; a typical EV drivetrain has fewer than 20. No oil changes, no transmission fluid, no spark plugs, no timing belt, no exhaust system. According to NREL research, EV owners spend approximately $0.061 per mile on maintenance versus $0.101 per mile for gas vehicles — a 40% reduction that compounds significantly over high-mileage ownership.

Over five years at 15,000 miles per year — 75,000 total miles — that difference amounts to $3,000 saved on maintenance alone. EV costs are not zero: tires wear faster due to torque and vehicle weight, brake fluid needs periodic replacement, and cabin air filters still require service. Budget around $1,500 in total maintenance for a mid-size EV over five years versus $4,500 for a comparable gas vehicle. The 40% per-mile maintenance gap is one of the most durable financial advantages for electric vehicle total cost of ownership, particularly for drivers who hold vehicles longer than three years.

The wildcard is battery health. Modern EV battery packs carry 8-year/100,000-mile warranties as a federal requirement, but gradual capacity loss still occurs during normal use. Typical lithium-ion packs lose 8–12% of range over five years under normal conditions. A degraded battery rarely requires full replacement within five years, but monitoring it matters if you plan to sell or trade in. Buyers in hot climates such as Texas and Florida see slightly faster degradation and should factor that into their five-year ownership projections.

Insurance is a meaningful offset to the maintenance advantage. EVs cost 5–15% more to insure than equivalent gas vehicles because repair costs for high-voltage battery modules, electric motors, and onboard chargers exceed conventional part costs, and fewer independent shops are equipped to handle them. On a mid-size sedan, expect to pay roughly $180–$250 more per year for EV coverage — approximately $1,000 additional over five years. Net of insurance, the EV still holds a maintenance and running-cost advantage of around $2,000 over five years compared to a gas equivalent.

Cumulative 5-year maintenance and insurance net advantage — EV saves approximately $2,000 vs gas

Resale Value, Depreciation, and Financing Costs

Depreciation is the single largest cost of car ownership for most drivers, yet it rarely appears in EV versus gas cost comparisons. A mid-size gas sedan typically retains about 42% of its original value after five years. A mid-size EV currently retains about 38% after five years — slightly lower, driven by rapid model-year updates and lingering battery uncertainty in the used vehicle market.

On the vehicles in this comparison: the gas car bought at $32,000 is worth approximately $13,440 after five years. The EV retains roughly $15,960 of its original $42,000 sticker — but measured against the effective $34,500 paid after the federal credit, that works out to about $13,110 in net residual value. When compared against actual out-of-pocket cost rather than sticker price, the two vehicles’ resale positions are broadly equivalent after five years.

Regional variation matters here. Texas and Florida EV buyers face a specific challenge: sustained heat accelerates battery degradation and suppresses used EV prices more than in cooler markets. The Pacific Northwest and Upper Midwest tend to show stronger EV residual values due to climate conditions and higher regional EV adoption rates, which support a more liquid secondary market for used electric vehicles.

Financing costs are a final variable worth including. At 6.5% APR over 60 months, the $34,500 EV purchase adds roughly $6,100 in interest. The gas car at $32,000 under identical terms adds approximately $5,680 — a $420 difference over the loan term. What matters more is whether you qualify for manufacturer financing promotions: in early 2026, several EV models are available with rates as low as 2.9% APR, which could save an additional $1,800 in interest compared to standard market rates over five years.

5-year depreciation and financing outcome — broadly equivalent between EV and gas when measured against net purchase price

True 5-Year Total Cost of Ownership: The Complete Breakdown

Adding every category together produces the complete comparison. All figures assume 15,000 miles per year, a 70/30 split between home and public charging for the EV, national average electricity and gasoline prices from the EIA, and the $7,500 federal tax credit applied to the EV purchase price.

EV total 5-year cost:

Effective purchase price (after $7,500 federal credit): $34,500. Fuel (electricity, home and public charging mix): $4,200. Maintenance: $1,500. Insurance premium over gas baseline: $1,000. Interest on financing at 6.5% APR: $6,100. Minus resale value: −$13,110. Net 5-year cost: $34,190.

Gas car total 5-year cost:

Purchase price: $32,000. Fuel (gasoline at $3.48/gallon): $8,160. Maintenance: $4,500. Insurance at baseline: $0 additional. Interest on financing at 6.5% APR: $5,680. Minus resale value: −$13,440. Net 5-year cost: $36,900.

The EV advantage at national average prices comes to approximately $2,710 over five years — or closer to $5,800 in a state with stacked incentives and moderate electricity rates. The gap narrows to near zero where electricity costs are high and gasoline is cheap, and it widens for high-mileage drivers whose annual fuel savings compound faster. The electric vehicle total cost of ownership advantage is real, but it is not uniform across every driver profile and region.

The broader household opportunity is also worth sizing. Drivers who install a Level 2 home charger — typically $800–$1,500 all-in after the federal 30C tax credit — and pair it with rooftop solar often find that combined energy savings outperform either investment on its own. For those evaluating whether home charging infrastructure is worth the setup cost, the EV charger install cost estimator is the right place to scope expenses before you commit. To generate a personalized five-year cost comparison using your actual state, electricity rate, annual mileage, and insurance figures, the EV vs gas calculator delivers a tailored number in under two minutes.
