Select Your EV or Enter Custom Battery
Choose your electric vehicle model from our comprehensive database or enter your custom battery capacity for accurate calculations.
Set Charging Range
Use the slider to set your typical charging range. Most EV owners charge from 20% to 80% for optimal battery health and daily use.
Enter Electricity Rate
Input your local electricity rate per kWh. Check your utility bill or use the US average of $0.13/kWh as a starting point.
💡 Calculation Method
Energy Needed: Battery Capacity × (Charging Percentage ÷ 100)
Total Cost: Energy Needed × Electricity Rate
Cost per Mile: Total Cost ÷ (Vehicle Range × Charging Percentage ÷ 100)
💰 Money-Saving Tips
- • Charge during off-peak hours for lower rates
- • Use time-of-use electricity plans
- • Consider home solar panels for cheaper electricity
🔋 Battery Health Tips
- • Avoid charging to 100% daily
- • Keep battery between 20-80% for longevity
- • Use fast charging sparingly
Understanding the fundamentals of electric vehicle charging costs
The Basic Formula
This simple formula is the foundation of all EV charging cost calculations
Step-by-Step Calculation Process
Step 1: Determine Energy Needed
Calculate how much energy your battery needs based on charging percentage:
Example: 75 kWh battery, charging from 20% to 80%
Energy = 75 × (80 - 20) ÷ 100 = 45 kWh
Step 2: Apply Electricity Rate
Multiply energy needed by your local electricity rate:
Example: 45 kWh × $0.13/kWh = $5.85
Step 3: Calculate Cost per Mile
Determine efficiency by dividing cost by range added:
Example: $5.85 ÷ 180 miles = $0.033 per mile
Factors That Affect Your Charging Costs
Time of Use
Electricity rates vary by time of day. Off-peak hours (typically 9 PM - 6 AM) can be 50% cheaper.
Location
Electricity rates vary by state. Hawaii ($0.33/kWh) vs Louisiana ($0.09/kWh) can triple your costs.
Charging Speed
Fast DC charging costs 2-3x more than home charging but saves time. Level 2 home charging is most economical.
Battery Size
Larger batteries cost more to fill but often provide better efficiency and longer range per charge.

Pro Tips for Accurate Calculations
Check Your Utility Bill
Look for the "Energy Charge" or "kWh Rate" on your electricity bill. This is more accurate than using averages.
Consider Time-of-Use Plans
Many utilities offer cheaper rates during off-peak hours. This can reduce your charging costs by 30-50%.
Track Your Actual Usage
Use your car's energy consumption display or a smart charger to monitor real-world efficiency.
Compare with Gas Costs
Calculate equivalent gas costs using: (Miles ÷ MPG) × Gas Price to see your savings.
