EV Charging Cost Calculator

Battery Information

Check your vehicle specs (e.g., Tesla Model 3: 75 kWh)

For cost per mile calculation

Charge Levels

Recommended: 80% for daily charging

Charging Costs

US average: $0.13/kWh (check your electric bill)

Level 2 home: ~90%, DC fast: ~85%

How to Use This Calculator

Calculate the cost to charge your electric vehicle from your current battery level to your target level. This accounts for charging efficiency loss and your local electricity rates.

Key Concepts:

  • Battery Capacity: Total kWh your battery can hold (found in vehicle specs)
  • Charging Efficiency: Energy lost as heat during charging (~10-15%)
  • Electricity Rate: Check your utility bill (varies by location and time of day)
  • 80% Rule: Daily charging to 80% maximizes battery longevity

Tip: Sign up for time-of-use rates and charge overnight to save 40-60% on electricity costs.
