Calculate how much it costs to charge your electric vehicle at home, public stations, or work. Enter your battery size, electricity rate, and desired charge level to get instant cost estimates. Free, private, and completely client-side.
Home chargers are ~90% efficient. Public DC fast chargers are ~95% efficient.
This free EV charging cost calculator helps electric vehicle owners estimate how much it costs to charge their car at home or at public charging stations. Enter your battery capacity, current and desired charge levels, electricity rate, and charging efficiency to get instant cost estimates, charging times, and cost-per-mile comparisons. All calculations happen 100% in your browser — no data is sent to any server.
The cost depends on your battery size, electricity rate, and charging efficiency. For a typical mid-size EV with a 65 kWh battery charging from 20% to 80% at $0.16/kWh, the cost is approximately $5.55. At EU rates (~€0.25/kWh), it would be about €8.67.
Home charging is almost always cheaper. Home electricity rates typically range from $0.10–$0.30/kWh, while public fast charging stations charge $0.30–$0.60/kWh or more. However, public charging is faster and more convenient for long trips.
Level 1 (120V home outlet) adds about 3–5 miles of range per hour. Level 2 (240V home charger) adds 25–40 miles per hour. DC Fast Charging at public stations can add 100–250 miles in 30 minutes depending on the vehicle and charger power.
Not all electricity drawn from the wall makes it into the battery. Some is lost as heat during AC-to-DC conversion. Home chargers are typically 85–92% efficient, while modern DC fast chargers are 93–96% efficient. This means you pay for slightly more electricity than what actually gets stored.
EVs typically cost $0.03–$0.06 per mile for electricity vs $0.10–$0.15 per mile for gasoline (depending on local prices and vehicle efficiency). This means EVs can save $500–$1,000+ per year on fuel costs.
Compact EVs typically have 40–50 kWh batteries. Mid-size sedans and crossovers usually have 60–80 kWh. Large SUVs and electric trucks can have 100–130+ kWh batteries. The average across all EVs sold today is approximately 65 kWh.
Yes, solar panels can significantly reduce or eliminate your EV charging costs. If your solar system generates enough power during the day, you can charge your EV for free. With home battery storage, you can even charge overnight using stored solar energy.
Level 1 uses a standard 120V household outlet and provides ~1.4 kW (slowest, no installation needed). Level 2 uses a 240V outlet or dedicated wall charger and provides 3–19 kW (most common for home charging). DC Fast Charging uses direct current at 50–350 kW (fastest, found at public stations for road trips).
