Enter your battery size (kWh), electricity rate (per kWh), and current charge level to find out exactly what it costs to fully charge your electric vehicle at home or at a public station. You'll also get the cost to drive a set distance based on your vehicle's efficiency — helping you budget smarter for every mile.

The cost depends on your battery size and local electricity rate. For a typical 75 kWh battery at $0.16/kWh, a full charge from empty costs about $12. At the US average rate, most EVs cost between $8 and $20 to fully charge at home.
The formula is simple: Charging Cost = Energy Needed (kWh) × Electricity Rate ($/kWh). Energy needed equals your battery capacity multiplied by the percentage you're charging (e.g., from 20% to 100% = 80% of total capacity). Our calculator handles this automatically.
EVs are typically 3–4x cheaper to fuel than gasoline cars. At $0.16/kWh with an efficiency of 30 kWh/100mi, driving costs roughly $0.05/mile. A comparable gas car at 30 MPG and $3.50/gallon costs about $0.12/mile — more than double.
The US national average is approximately $0.13–$0.16 per kWh for residential electricity. Rates vary by state — Hawaii averages over $0.30/kWh while states like Louisiana are closer to $0.10/kWh. Check your utility bill for your exact rate.
Public DC fast chargers typically cost $0.25–$0.50 per kWh, which is 2–3x more expensive than home charging. Some networks like Tesla Supercharger or Electrify America charge around $0.35/kWh. Home charging remains the most cost-effective option for daily use.
This depends on the battery size and how depleted it is. A fully depleted 75 kWh battery needs about 75 kWh to reach 100% (accounting for small charging losses). Compact EVs may have 40–50 kWh batteries, while larger EVs like the Rivian R1T can have 135+ kWh batteries.
Most modern EVs average 25–35 kWh per 100 miles. The Tesla Model 3 is among the most efficient at about 25 kWh/100mi. Larger SUVs and trucks use more — typically 35–50 kWh/100mi. Lower numbers mean better efficiency and lower per-mile charging costs.
Most EV manufacturers recommend keeping daily charging between 20% and 80–90% to preserve long-term battery health. Charging to 100% is fine for long trips but doing it regularly can degrade lithium-ion battery capacity over time. Check your vehicle's manual for specific recommendations.
