Home EV Charging Basics
⚡ Level 2 Charging
A Level 2 (240V) home charger adds 20–30 miles of range per hour — enough to fully recharge overnight. It costs $1,200–$2,000 installed, versus a standard outlet (Level 1) that adds only 3–5 miles per hour.
💰 Home vs Gas vs Public
Charging at home costs roughly a third of gasoline per mile, and about half of public charging. Your savings depend on your local electricity rate, gas prices, and how far you drive — the calculator shows all three.
🏛️ Federal 30C Credit (Expired)
The 30% federal charger credit (up to $1,000) expired June 30, 2026. It had also only applied in eligible low-income or non-urban census tracts. State and utility charger rebates and EV time-of-use rates are now the main incentives.
🌙 Off-Peak Charging
Many utilities offer special EV rates for charging overnight, when electricity is cheapest. Scheduling your charging for off-peak hours can cut your home charging cost further — often below $0.10/kWh.
Free EV Charger Calculator FAQ
Is this EV charger calculator really free?
Yes. Our EV charger calculator and home charging estimator are 100% free — no email, phone number, or sign-up required. Enter your annual miles and state to get an instant estimate.
Do I have to enter my email or phone number?
No. The estimator runs entirely in your browser and asks for nothing personal. You only share contact details later if you choose to request quotes from installers.
How accurate is the charging estimator?
It uses real, state-by-state data — your local electricity rate, gas prices, and how far you drive. It is a strong planning estimate; a licensed electrician confirms exact install cost for your panel and garage.
What information do I need to use it?
Just your annual miles driven and your state. The calculator estimates your home-charging fuel savings versus gas, the cost to install a Level 2 charger, available rebates, and payback.
Does the calculator include the federal EV charger tax credit?
The 30% federal charger credit (30C, up to $1,000) expired June 30, 2026, and only applied in eligible census tracts. Our estimates do not assume it — the calculator instead reflects the state and utility charger rebates and EV rates available where you live.
How does the calculator estimate my savings?
It compares the cost of charging at home — your local electricity rate times the kWh your driving needs — against buying gasoline for the same miles, then factors in charger install cost and rebates to show payback.
