How to use

1 Enter your EV's battery capacity in kWh. Common: Tesla Model Y 75 kWh, Ford Mustang Mach-E 88 kWh, Hyundai Ioniq 5 77 kWh, Chevy Bolt 65 kWh.
2 Enter the EPA-rated efficiency in miles per kWh (or mi/kWh). Most modern EVs: 3–4 mi/kWh; pickups (F-150 Lightning, Cybertruck) ~2 mi/kWh.
3 Enter the kWh price for your charging scenario: home (use your utility bill — US average $0.1765/kWh), workplace (often free), public Level 2 ($0.25–$0.40), or DC fast ($0.40–$0.65).
4 Click Calculate to see cost per full charge, cost per mile, and projected annual cost at your typical driving.
5 For long-distance trips, build in 25–40% margin — DC fast chargers in California, NY, and tourist areas often charge premium pricing during peak hours.

EV Charging Cost by Location

Location	Typical price	Notes
Home Level 1 (120V)	$0.10–$0.20/kWh	3–5 miles per hour charging — overnight only
Home Level 2 (240V)	$0.10–$0.20/kWh	20–40 mph charging — most US EV owners' primary method
Workplace	Often free or $0.10/kWh	Common employee benefit at tech and Fortune 500
Public Level 2	$0.25–$0.40/kWh	ChargePoint, Blink, EV Connect
Tesla Supercharger	$0.30–$0.55/kWh	Off-peak cheaper, peak summer noon expensive
Electrify America DC fast	$0.36–$0.56/kWh	Pass+ $4/mo unlocks lower rate
EVgo DC fast	$0.39–$0.59/kWh	Membership cuts ~25%

Cost Per Mile: EV vs. Gas

A typical EV at 3.5 mi/kWh on home electricity at $0.18/kWh costs 5.1¢ per mile. A 30-MPG gas car at $3.20/gal costs 10.7¢ per mile — EV is 52% cheaper. On DC fast charging at $0.50/kWh, EV cost rises to 14.3¢ per mile — actually more than the gas car. This is why home charging is the EV economy story.

Federal and State EV Charging Incentives

The Federal Alternative Fuel Vehicle Refueling Property Credit covers 30% of home Level 2 charger installation cost, up to $1,000 per charger (current law through 2032). State and utility programs add more — California PG&E offers $700–$1,000 EV charger rebate; Colorado tax credit $5,000 for new EVs; New York charging station rebate $4,000. Check your state energy office and utility for current programs.

Charging Speed Reference

Charger type	Power	Range added per hour

Level 2 (240V home)	7.7 kW	25–30 miles
Level 2 commercial	11.5–19.2 kW	35–60 miles
DC fast (50 kW)	50 kW	~150 miles
DC fast (150 kW)	150 kW	~450 miles (until 80% taper)
Tesla Supercharger V3	250 kW	~750 miles (until 80% taper)

FAQ

Q How much does it cost to charge a Tesla at home?

Tesla Model Y (75 kWh battery, ~3.6 mi/kWh) at the US average $0.1765/kWh costs about $13.24 per full charge from empty to 100%. That gives roughly 270 miles of range, working out to about 5 cents per mile — much cheaper than 30-MPG gas at $3.20/gal (about 10.7 cents/mile).

Q How much does Supercharger cost on a road trip?

Tesla Superchargers run $0.30–$0.55/kWh depending on time of day and location. A 75-kWh battery refill costs $22–$41 per stop. Off-peak pricing (typically 6 PM–10 AM in many regions) saves 30–40%. Tesla's in-car nav shows pricing per stall before you arrive.

Q Is home Level 2 charging worth installing?

For most EV owners with a garage or driveway, yes. The federal 30% tax credit covers up to $1,000 of installer cost; state utilities often add $400–$1,000 more. Net out-of-pocket commonly $500–$1,500 for a complete install. Charges 6× faster than Level 1 — full overnight charge instead of 1–2 days.

Q How much does it cost to charge an EV at a public station?

Highly variable. Free at some workplaces and shopping centers; $0.25–$0.40/kWh at most public Level 2 stations (ChargePoint, Blink); $0.40–$0.65/kWh at DC fast chargers. A 70-kWh charge from 10–80% (roughly 50 kWh added) costs $20–$33 at typical DC fast stations, more on expensive networks.

Q Why is DC fast charging more expensive than home?

DC fast chargers cost $40,000–$200,000 each to install plus high demand-charge electricity rates from utilities. Operators (Tesla, Electrify America, EVgo) need to recoup that capital, and they price based on convenience for road trips, not daily commuting. Home charging is by far the cheapest method — for owners without home charging, EV economics break down.

Q Should I charge to 100% every night?

For lithium-ion batteries (most EVs), 80% daily charging extends battery life. Charge to 100% only before long trips. Tesla, Ford, Hyundai, and most EV apps let you set a daily charge limit. Battery degradation adds up over years — a Tesla charged daily to 100% may lose 5–10% more capacity over 100K miles than one charged to 80%.

Q How long does an EV battery last?

Modern EV batteries typically last 200,000–300,000 miles with normal use. Manufacturers warranty 8 years / 100,000 miles minimum (federal requirement) — Hyundai, Kia, and others offer 10 years / 100,000 miles. Most lose 10–15% capacity in first 100K miles, then degradation slows.

Q Do EVs need oil changes?

No — they have no engine oil. EVs need: tire rotation every 5,000–7,500 miles, brake fluid replacement every 2 years, cabin air filter annually, and battery coolant every 100,000 miles or so. Annual maintenance typically runs $300–$600, vs. $800–$1,500 for a comparable gas car (per AAA).
