A 7,200 watt EV charger costs about $2.45 to run for 2 hours at $0.17 per kWh.
Quick estimate
This uses 7200 watts, 2 hours per day, and an electricity rate of $0.17 per kWh.
EV charging cost is usually better estimated from kWh added to the battery, but charger watts can estimate session cost.
Many electric vehicle charger units fall around 7200 watts, with a rough range of 1400 to 11500 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 1400W | 1 | $0.24 | $7.14 |
| Typical use | 7200W | 2 | $2.45 | $73.44 |
| High estimate | 11500W | 3 | $5.87 | $175.95 |
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this electric vehicle charger example: 7200 / 1000 x 2 x 0.17 = $2.45 per day.
These details make this estimate more useful for real-world use.
For electric vehicles, the most accurate everyday estimate is usually the number of kWh added to the battery multiplied by your electricity rate. Charger wattage and hours are still useful when planning a charging session.
Some utility plans charge much less overnight and more during peak hours. If you have time-of-use pricing, enter the rate that applies when you normally charge.
Charge during lower-rate periods if your utility offers time-of-use pricing.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
