EV Charging Cost Calculator: How Much It Really Costs to Charge Your Electric Car (2026)

The short answer

Charging an electric vehicle at home costs $0.03–$0.06 per mile in 2026, depending on your local electricity rate and EV efficiency. Public Level 2 charging runs $0.08–$0.12 per mile, while DC fast-charging costs $0.10–$0.18 per mile. A driver covering 1,000 miles monthly pays $40–$70 charging at home versus $120–$180 in gasoline for a 30-mpg car at $3.60/gallon.

How home charging costs break down

Your home charging cost equals your electricity rate multiplied by your EV's efficiency. The average US residential rate in 2026 is $0.14 per kWh. A typical EV uses 3.0–3.5 kWh per 10 miles.

Calculate cost per mile: (kWh per mile) × (your electricity rate). A Tesla Model 3 uses 0.25 kWh per mile. At $0.14/kWh, that's $0.035 per mile. A Ford F-150 Lightning uses 0.48 kWh per mile, costing $0.067 per mile at the same rate.

Monthly cost for 1,000 miles: multiply your per-mile cost by miles driven. The Model 3 driver pays $35; the Lightning driver pays $67. Check your actual utility rate on your latest electric bill—rates range from $0.10/kWh in Louisiana to $0.32/kWh in California.

Off-peak rates cut costs 30–50 percent. Time-of-use plans charge $0.08–$0.10/kWh between 9 PM and 6 AM in most markets. Set your EV to charge overnight and the same 1,000 miles drops to $25–$40.

Public charging costs by charger type

Level 2 public chargers cost $0.20–$0.40 per kWh or $1.50–$3.00 per hour. At $0.30/kWh, a Model 3 pays $0.075 per mile. ChargePoint and EVgo networks publish rates in their apps; hotel and workplace chargers often provide free Level 2 access.

DC fast-charging costs $0.35–$0.60 per kWh in 2026. Electrify America charges $0.48/kWh for non-members; Tesla Superchargers average $0.42/kWh. The Model 3 pays $0.105 per mile; the Lightning pays $0.20 per mile. A 250-mile road trip costs $26–$50 depending on vehicle and network.

Idle fees add $0.40–$1.00 per minute after charging completes. Move your car within 5 minutes of reaching 80 percent to avoid $12–$30 in penalties on a 30-minute session.

How to calculate your monthly charging bill

Estimate monthly miles driven. Check your odometer or insurance telematics: the average US driver covers 1,100 miles monthly.

Find your EV's EPA efficiency rating in kWh per 100 miles. The window sticker or manufacturer website lists this. Divide by 100 to get kWh per mile. A Chevrolet Bolt lists 28 kWh/100 miles = 0.28 kWh per mile.

Multiply miles × kWh per mile × your electricity rate. For 1,100 miles at $0.14/kWh: 1,100 × 0.28 × $0.14 = $43.12.

Add your current monthly electric bill to see total impact. A household paying $110/month sees a 39 percent increase to $153. Install a separate meter to track EV-only usage if your utility offers EV-specific rate plans.

Worked example

Sarah drives a 2026 Hyundai Ioniq 5 (rated 27 kWh/100 miles or 0.27 kWh per mile) in Austin, Texas, where electricity costs $0.13/kWh.

Monthly driving: 950 miles (750 commuting, 200 errands). She charges 90 percent at home overnight on a time-of-use plan at $0.09/kWh and 10 percent on Electrify America fast-chargers at $0.48/kWh.

Home charging: 855 miles × 0.27 kWh/mile × $0.09/kWh = $20.79. Public charging: 95 miles × 0.27 kWh/mile × $0.48/kWh = $12.31. Total monthly charging cost: $33.10.

Gas comparison: Sarah's previous Honda Accord averaged 32 mpg. At $3.50/gallon in Austin: 950 miles ÷ 32 mpg × $3.50 = $103.91. Monthly savings: $70.81, or $850 annually.

Five-year savings: $4,250 in fuel alone. Subtract the $1,200 cost of her Level 2 home charger install for net savings of $3,050 over five years, before factoring in lower maintenance.

Factors that increase or decrease your cost

Temperature extremes reduce efficiency 20–40 percent. Heating the cabin in 20°F weather or running AC in 95°F heat increases consumption to 0.35–0.45 kWh per mile. Budget an extra $15–$25 monthly in January and July.

Driving style matters. Aggressive acceleration and highway speeds above 70 mph cut range 15–25 percent. Regenerative braking and steady 55-mph cruising improve efficiency to 0.22–0.26 kWh per mile.

Charger installation costs $800–$2,500 one time. A basic 240V outlet runs $800; a hardwired Level 2 unit costs $1,500–$2,500 installed. Federal tax credits cover 30 percent of install costs up to $1,000 through 2032. Your utility may offer $250–$500 rebates.

What to do next

1. Check your electricity rate on your latest utility bill and look for time-of-use or EV-specific rate plans. Call your provider to ask about off-peak hours and whether you qualify for EV discounts. Switching to time-of-use saves $180–$300 yearly.

2. Find your EV's EPA kWh/100 miles rating on the window sticker or at fueleconomy.gov. Multiply by 0.01, then multiply by your monthly miles and electricity rate to estimate your monthly charging cost. Compare this to your current gas expense (monthly miles ÷ mpg × price per gallon).

3. Download apps for public charging networks in your area—ChargePoint, Electrify America, EVgo, and Tesla—to compare per-kWh rates and locate free Level 2 chargers at shopping centers and employers. Membership plans ($4–$7/month) cut fast-charging rates 10–25 percent if you road-trip monthly.
