Ev Charging Home Nasıl Hesaplanır?
learn.whatIsHeading
The Home EV Charging Cost Calculator estimates your monthly and annual cost to charge an electric vehicle at home using your local electricity rate, daily driving distance, and vehicle efficiency.
Formül
Monthly Charging Cost = (Monthly Miles / Efficiency in mi/kWh) x Electricity Rate ($/kWh)
- D
- Monthly Driving Distance (miles) — Total miles driven per month
- E
- Vehicle Efficiency (mi/kWh) — Miles traveled per kWh of energy consumed
- R
- Electricity Rate ($/kWh) — Your fully loaded electricity cost per kilowatt-hour
- L
- Charging Loss Factor (%) — Energy lost as heat during charging, typically 10-15%
Adım Adım Kılavuz
- 1Enter your daily or monthly driving distance in miles
- 2Input your vehicle efficiency in miles per kWh (check your EV dashboard)
- 3Enter your home electricity rate in dollars per kWh from your utility bill
- 4The calculator divides miles by efficiency to get kWh needed, then multiplies by your rate

Giriş
1,000 miles/month, 3.5 mi/kWh, $0.13/kWh
Sonuç
(1000 / 3.5) x $0.13 = $37.14/month ($445.71/year)
Giriş
1,000 miles/month, 3.5 mi/kWh, $0.30/kWh (CA rate)
Sonuç
(1000 / 3.5) x $0.30 = $85.71/month ($1,028.57/year)
Kaçınılması Gereken Yaygın Hatalar
- ✕Using the base electricity rate without adding delivery charges, taxes, and fees which can double the effective rate
- ✕Not considering time-of-use rates — charging at off-peak hours (11 PM - 7 AM) can save 30-50%
- ✕Forgetting charging losses of 10-15% from the wall to the battery, meaning you pay for more kWh than the car actually stores
Sık sorulan sorular
How much does it cost to charge an EV at home?
The average US household pays about $0.16/kWh, which means charging a typical EV (3.5 mi/kWh) costs roughly $0.046 per mile, or about $45-55 per month for 12,000 miles per year.
Is it cheaper to charge at home or at a public station?
Home charging is almost always cheaper. Home rates average $0.10-0.30/kWh, while DC fast chargers cost $0.30-0.60/kWh — often 2-4x more expensive.
Do I need a Level 2 charger at home?
A Level 1 charger (standard 120V outlet) adds about 4-5 miles of range per hour. If you drive under 40 miles daily, Level 1 may suffice. Level 2 (240V) adds 25-30 miles per hour and is recommended for most EV owners.
