I get ~3.5mi/kWh in my EV with how I drive. I pay ~$0.11/kWh for electricity including delivery.

The average US driver drives ~13,000mi/yr. We'll make the math easier and just say you drive ~1,000mi/mo.

1000 mi / 3.5 mi/kWh = 285.7kWh per month. At $0.11/kWh, that's ~$31.43 added to the bill.

Gas around me has been around $3/gal for a while. Average US car fuel economy is like 25mpg, which is a bit better than the car my EV replaced. 1000 mi / 25mpg = 40 gallons of gas, * $3/gal gives ~$120 per month. If I had a 40mpg car, it would cost ~$75/mo in gas. I'd need close to 100mpg in an ICE car to get to the same fuel cost.
