EV Charging Cost Calculator

Estimate electric vehicle charging cost, kWh needed, wall energy, charging losses, charge time, cost per mile, cost per 100 miles, monthly charging cost, and annual EV charging cost.

Calculate EV Charging Cost

EV Charging Cost = Wall Energy Needed × Electricity Rate + Fees.

How the EV charging cost calculator works

Single charge cost:
Uses battery capacity, starting charge, target charge, charging efficiency, electricity rate, and fees to estimate one charging session.

Trip charging cost:
Uses trip distance and kWh per mile to estimate trip energy use and charging cost.

Monthly charging cost:
Uses monthly miles, EV efficiency, home charging share, home electricity rate, and public charging rate.

Charging time:
Uses wall energy needed and charger power to estimate hours needed to charge.

Why use an EV charging cost calculator?

An EV charging cost calculator helps estimate how much it costs to charge an electric vehicle at home, at work, or on public chargers.

It can help compare home charging, public charging, monthly driving cost, road trip cost, and cost per mile.

What your result means

Your result shows single charge cost, battery energy added, wall energy needed, charging losses, charge time, trip cost, monthly charging cost, annual charging cost, cost per mile, and cost per 100 miles. These are estimates based on the values you enter.

Frequently asked questions

How do you calculate EV charging cost?

Multiply the wall energy used in kWh by the electricity rate per kWh, then add any session fees or idle fees.

Why is wall energy higher than battery energy?

Charging is not perfectly efficient. Some energy is lost as heat or used by charging electronics, battery conditioning, and vehicle systems.

How do you estimate EV cost per mile?

Multiply kWh per mile by the effective electricity rate per kWh, adjusted for charging losses.

Is public charging more expensive than home charging?

Public charging is often more expensive, especially fast charging, but the actual cost depends on the charging network, location, time of day, and pricing plan.
