EV charging cost calculator
What an EV charge actually costs at home vs DC fast-charge: kWh per 100mi × $/kWh, with day/night utility rate windows.
Monthly EV charging cost
$6.97 per 100 miles
Savings vs gas
Gas estimate: $133.93 per month

- Fast charging energy62.2 kWh
- Gas comparison cost$133.93
EV charging cost is a blended energy-price problem
The core formula is:
Monthly kWh = miles x kWh per 100 miles / 100
Then adjust for charging losses and split the energy between home charging and fast charging.
The gas comparison is:
Gas cost = miles / MPG x price per gallon
Use the blended result to evaluate commute cost, road-trip charging, time-of-use rates, and whether installing a home charger changes the economics enough to matter.
