📐 How We Calculate

View methodology & assumptions

Electricity cost = Rate (¢/kWh) × Energy used (kWh).
Energy used = Daily miles ÷ Efficiency (mi/kWh).
Charge time = Battery size (kWh) ÷ Charger power (kW).
Gas comparison = (Daily miles ÷ 25 MPG) × Gas price per gallon.

  • Rates: State-average residential rates from EIA (2024).
  • Gas prices: State-average regular unleaded from AAA (2024).
  • TOU: 20% discount for off-peak charging.
  • Efficiency: EPA combined mi/kWh.
  • Assumptions: 25 MPG for gas cars, 85% charging efficiency.
  • Accuracy: Typically within 5–7% of actual costs.

⚠️ Estimates are for comparison. Actual costs vary by driving habits, weather, and utility rates. Data updated quarterly.

📉 Factors That Affect Your EV Charging Cost

⚡ Utility Rates

Rates vary from 10¢ (WA) to 40¢ (HI) per kWh. Your ZIP code determines the local rate.

🚗 Vehicle Efficiency

More efficient EVs (e.g., Tesla Model 3) cost less per mile than larger EVs (e.g., Rivian).

⏱️ Time‑of‑Use

Charging during off‑peak hours can lower your rate by 20% or more.

🌤️ Weather & Driving

Cold weather and aggressive driving reduce efficiency, increasing cost.

🔌 Charger Speed

Faster chargers (Level 3) are more expensive and less efficient than Level 2.

📏 Daily Miles

More miles = higher cost, but also higher savings vs. gas.

💡 Tips to Reduce Your Charging Cost

  • Charge off‑peak: Use TOU plans to save up to 20% on your electricity bill.
  • Install a Level 2 charger: Faster charging reduces energy loss (85–90% efficiency vs. 75–80% for Level 1).
  • Combine with solar: Generate your own electricity for near‑zero charging cost.
  • Choose an efficient EV: Higher mi/kWh = lower cost per mile.
  • Maintain tire pressure: Under‑inflated tires reduce efficiency by up to 5%.
  • Use smart charging: Schedule charging to start when rates are lowest.

🚫 Common Mistakes to Avoid

  • Ignoring TOU rates: Charging at peak times can double your cost.
  • Using the wrong efficiency figure: Real‑world efficiency is often 10–15% lower than EPA.
  • Forgetting charging losses: 85–90% efficiency means you pay for more energy than goes into the battery.
  • Not accounting for installation: Home charger installation adds upfront cost ($500–$2,000).
  • Overlooking maintenance savings: EVs save on oil changes, brake pads, and engine repairs.
  • Using public charging exclusively: Public charging costs 30–50% more than home charging.

❓ Frequently Asked Questions

This calculator uses state‑average electricity and gas prices from official sources (EIA, AAA). Actual costs vary based on your specific utility plan, driving conditions, and charging habits. For the most accurate estimate, use the custom rate override with your actual electricity bill. Accuracy is typically within 5–7%.
Yes! Toggle the TOU switch to see how off‑peak charging can lower your costs. When TOU is enabled, we apply a 20% discount to the electricity rate, reflecting typical off‑peak savings. Check with your utility for exact TOU rates.
Home charging uses your residential electricity rate. Public charging typically costs more (we add a 30% premium). Workplace charging is often subsidized (we apply a 10% discount). The calculator adjusts the rate based on your selection.
Check your monthly utility bill for the rate per kWh (kilowatt‑hour). It's usually listed as "electricity charge" or "energy charge." You can also look up your utility's website or call them directly. Enter your rate in the "Override Electricity Rate" field for a personalized estimate.
Electricity rates and gas prices vary significantly by state and region due to differences in energy sources, taxes, infrastructure, and regulations. This calculator uses state‑level averages to give you a localized estimate.
Yes! The calculator is designed for individual use, but you can run multiple scenarios to estimate fleet costs. For larger fleets, we recommend consulting with an energy advisor for more precise modeling.
Yes. We assume 85% charging efficiency for Level 2 (AC) home charging, meaning you pay for more energy than actually goes into the battery. Level 1 is assumed at 80% efficiency.
After calculating, click the "Share" button to copy a unique link with your parameters. You can share it via email, social media, or messaging.
Not directly, but you can manually reduce your EV's efficiency by 10–20% in the winter to simulate increased energy consumption. Many EVs see a 15‑30% range drop in freezing temperatures.
No. This calculator focuses on ongoing charging costs. However, we recommend budgeting $500–$2,000 for Level 2 charger installation. Check your local incentives for potential rebates.
The average U.S. residential electricity rate is ~16.5 ¢/kWh. For a typical EV with 3.5 mi/kWh efficiency, home charging costs about $0.047 per mile. A 40‑mile daily commute costs ~$1.88 per day or ~$56 per month.
Public Level 2 charging typically costs 30–50% more than home charging. DC fast charging can cost even more — often $0.30–$0.60 per kWh. Some networks offer subscription plans for lower rates.
Yes — significantly. On average, EV charging costs about 50–70% less than gasoline per mile. Savings vary by state, but the average EV owner saves $800–$1,500 per year compared to a 25 MPG gas car.
For the most accurate estimate: (1) Enter your exact ZIP code, (2) Select your specific vehicle model, (3) Use your actual daily mileage, (4) Enter your actual electricity rate from your utility bill using the "Override" field, and (5) Enable TOU if you charge off‑peak.
Not directly. However, we recommend checking the federal EV tax credit (up to $7,500) and your state's rebate programs. Many states also offer additional incentives for home charger installation.
