How Much Does It Cost to Charge an Electric Vehicle at Home?
Charging an electric vehicle (EV) at home is almost always significantly cheaper than filling a gasoline car at the pump. However, exact charging costs depend on your vehicle’s battery capacity, efficiency rating, local electric rate per kWh, and whether you charge during off-peak utility hours.
This EV Charging Cost Calculator includes a standard 10% charging loss adjustment (energy lost as heat during transfer) to give you an accurate real-world cost estimate for full charges, monthly commuting, and annual home electricity expenses.
EV Home Charging Cost Formula
To calculate your electric vehicle charging expense manually:
- Full Charge Cost:
(Battery Capacity in kWh × 1.10 Charging Loss Factor) × Electricity Rate ($/kWh) - Cost Per 100 Miles:
(100 ÷ Vehicle Efficiency in Mi/kWh) × 1.10 × Electricity Rate ($/kWh) - Monthly Charging Cost:
(Monthly Driving Miles ÷ Vehicle Efficiency) × 1.10 × Electricity Rate ($/kWh)
Average EV Home Charging Costs Comparison
Assuming a standard electricity rate of $0.16 per kWh and 1,000 miles driven per month:
| Vehicle Class & Battery Size | Full Charge Cost (0-100%) | Cost Per 100 Miles | Estimated Monthly Cost |
| Compact EV (60 kWh) | $10.56 | $4.57 | $45.71 |
| Mid-Size SUV / Sedan (75 kWh) | $13.20 | $5.03 | $50.29 |
| Performance / Large SUV (100 kWh) | $17.60 | $6.10 | $60.95 |
| Electric Pickup Truck (130 kWh) | $22.88 | $8.38 | $83.81 |
Frequently Asked Questions
Is it cheaper to charge an EV at home or at a public station?
Charging at home is almost always 50% to 70% cheaper than using public DC fast chargers. Public fast-charging stations often charge $0.35 to $0.50 per kWh, whereas residential electricity averages between $0.12 and $0.18 per kWh in most regions.
What is time-of-use (TOU) charging?
Many electric utility companies offer Time-of-Use rates that discount electricity costs significantly during off-peak hours (typically late night to early morning). Setting your EV or home wall charger to start charging after 11:00 PM can cut your charging costs in half.
How much do you save on gas with an electric car?
The average gas-powered car costs roughly $0.13 to $0.18 per mile in fuel, while an electric vehicle charged at home costs around $0.04 to $0.06 per mile. Driving 12,000 miles per year in an EV typically saves $1,000 to $1,500 in fuel costs annually.
