4

Compare vs. Gas

Switch to the vs Gas Comparison tab, enter your equivalent MPG and local gas price, and see your exact annual fuel savings.

Daily EV Charging Cost

Daily Cost = (Home kWh × Home Rate) + (DCFC kWh × DCFC Rate)

Daily kWh demand is (daily miles ÷ mi/kWh) ÷ charging efficiency. That demand is then split between home and DCFC portions by the % charged at home setting.

Cost per Mile

Cost/mile = Daily EV Cost ÷ Daily Miles

Divides total daily electricity cost by miles driven, giving a per-mile fuel cost directly comparable to a gas vehicle's cents-per-mile.

Annual Fuel Savings

Savings = (Miles/yr ÷ MPG × Gas Price) − Annual EV Cost

Computes the full-year gas spend for an equivalent ICE vehicle and subtracts your annual EV electricity cost. Positive values mean EV is cheaper.

kWh (Kilowatt-hour) The unit of energy used for both battery capacity and electricity billing — a 75 kWh battery stores 75 kilowatt-hours of energy.

Efficiency (mi/kWh) The distance your EV travels per kilowatt-hour, ranging from roughly 1.4 mi/kWh (Hummer EV) to 5.5 mi/kWh (Lucid Air).

Level 1 Charging Standard 120V household outlet delivering roughly 1.2 kW, adding 3–5 miles of range per hour — adequate for low-mileage drivers.

Level 2 Charging Dedicated 240V circuit delivering 7–11 kW, adding 20–30 miles of range per hour — the standard home charging setup.

DC Fast Charging (DCFC) Direct-current charging at 50–350 kW that can bring most EVs from 20% to 80% in 15–45 minutes, typically at 2–3× home charging rates.

Charging Efficiency The fraction of grid energy that actually enters the battery; Level 2 home charging is roughly 90% efficient, DCFC about 92%.

TOU (Time-of-Use) Rates Utility pricing that varies by time of day, with off-peak overnight rates often 30–60% cheaper than daytime peak rates.

Annual Fuel Savings The difference between what you would spend on gasoline vs. what you spend on electricity for the same mileage, expressed per year.

F-150 Lightning vs. Gas F-150

Vehicle Ford F-150 Lightning (2.0 mi/kWh) Daily miles 50 miles Home rate $0.15/kWh (80% home) Gas equivalent 20 MPG at $3.50/gal

Despite lower EV efficiency, annual savings vs. a gas F-150 still top $1,600/year — truck drivers see some of the largest absolute fuel savings from going electric.

No home charger — relies on public DCFC

Vehicle Tesla Model Y LR (3.9 mi/kWh) Daily miles 35 miles DCFC rate $0.45/kWh (10% home) Gas equivalent 28 MPG at $3.50/gal

Heavy DCFC reliance raises annual EV cost to ~$1,440, narrowing savings vs. gas to ~$100/year. This shows why home charging access matters so much for EV economics.

The answer depends on three things: where you charge, how efficient your vehicle is, and how much you drive. This guide breaks down the full cost picture — from overnight home charging to highway fast stops — and shows exactly how much you can save compared to gasoline.

Home Charging: Your Biggest Cost Lever

Home Level 2 charging is almost always the cheapest way to power your EV, typically costing $0.10–$0.28/kWh depending on your state. The single best move most EV owners can make is asking their utility about EV or time-of-use (TOU) rate plans. Overnight off-peak rates as low as $0.05–$0.09/kWh are available in many regions, cutting charging costs by 30–60% compared to daytime peak rates.

A Level 2 home charger (240V, 7–11 kW) costs $600–$1,500 installed and qualifies for the federal 30% tax credit. It pays back quickly: at $0.14/kWh for a 40-mile daily commute, home Level 2 costs about $1.40/day versus $4.67/day for a 30 MPG gas car at $3.50/gal — roughly $1,200/year in fuel savings alone.

DC Fast Charging and Its Hidden Cost

DC fast chargers are essential for road trips but expensive for daily use. At $0.30–$0.60/kWh, public DCFC can cost 2–4× your home rate. For a driver who relies entirely on public charging (no home access), annual electricity costs can approach or even exceed the equivalent gas cost depending on local rates.

The takeaway: maximize the percentage you charge at home. Even moving from 60% to 85% home charging can save $200–$400/year. The % Charged at Home slider in this calculator lets you model the exact impact for your vehicle and rates.

EV vs. Gas: Where the Real Savings Are

For most US drivers covering 12,000–15,000 miles per year, annual fuel savings of $800–$1,500 are realistic when switching from a 28–35 MPG gas vehicle to an EV charged primarily at home. Larger, less efficient EVs (trucks, SUVs) show higher absolute savings simply because the gas alternative burns more fuel. At $3.50/gal, a 20 MPG gas truck costs $2,625/year in fuel; even an inefficient 2.0 mi/kWh EV charged at $0.15/kWh for the same mileage costs just $1,125 — saving $1,500 annually.

These savings compound over time as gasoline prices fluctuate upward and electricity rates remain more stable (especially with a fixed TOU rate plan). Running the Monthly Budget tab for a full 12-month view shows just how consistent the savings are month to month.

How much does it cost to charge an EV at home per month?+

For a typical 40-mile daily commute with a 4 mi/kWh EV, you'll use about 10 kWh/day or ~300 kWh/month. At the US average of $0.15/kWh, that's about $45/month. In California at $0.28/kWh it's ~$84; in low-rate states like Louisiana (~$0.09/kWh) it's just $27.

Is Level 2 or DC fast charging cheaper?+

Home Level 2 is almost always cheaper — typically $0.10–$0.20/kWh versus $0.30–$0.60/kWh for DC fast chargers. On a per-mile basis, home Level 2 costs 2.5–5¢/mile while DCFC costs 7–15¢/mile. Maximizing home charging is the single most effective way to lower your EV operating cost.

How much does an EV save vs a gas car per year?+

For 12,000 miles/year: a 4 mi/kWh EV at $0.15/kWh costs ~$450 in electricity, while a 28 MPG gas car at $3.50/gal costs ~$1,500 — about $1,050 in annual savings. F-150 Lightning owners save more because their gas comparison (15–20 MPG) is so much worse. Use the vs Gas tab to calculate your exact number.

What is the cost per mile for an electric vehicle?+

At $0.15/kWh: 5.5 mi/kWh Lucid Air = 2.7¢/mile; 4.0 mi/kWh Tesla Model 3 = 3.8¢/mile; 2.0 mi/kWh F-150 Lightning = 7.5¢/mile. Gas at $3.50/gal: 30 MPG = 11.7¢/mile; 20 MPG = 17.5¢/mile. EVs are 2–5× cheaper per mile when charged at home.

How long does it take to charge an EV overnight?+

A Level 2 home charger delivers about 7.2 kW. For a 40-mile commute (roughly 10–12 kWh needed), it takes 1.4–1.7 hours. For a full charge of a 75 kWh battery from empty, expect 10–11 hours. Level 1 (120V) takes 5–6× longer for the same energy. Most EV owners simply plug in every evening and wake to a full battery.

Does cold weather increase charging costs?+

Yes — cold weather reduces range 20–40%, so you'll charge more often to cover the same miles. In winter, budget 20–30% more electricity consumption and reduce your expected mi/kWh by 15–25%. The % Charged at Home setting doesn't change in winter, but the total kWh consumed increases, directly raising your monthly cost.

Why does % charged at home matter so much?+

Home charging typically costs $0.10–$0.20/kWh while DCFC costs $0.30–$0.60/kWh. If you charge 50% at home and 50% via DCFC, your blended rate can be 2× your home rate, eroding most of the savings vs. gasoline. Aim for 80%+ home charging to maximize the cost advantage of EV ownership.

What is the difference between Level 1, Level 2, and DC fast charging?+

Level 1 (120V) delivers ~1.2 kW and adds 3–5 miles/hour — fine for low-mileage drivers. Level 2 (240V) delivers 7–11 kW and adds 20–30 miles/hour, covering most overnight home needs. DC Fast Charging delivers 50–350 kW and can add 100–400 miles/hour, filling most packs to 80% in 15–45 minutes at highway rest stops.
