Frequently asked questions

How do I calculate gas cost for my car?

Divide the miles you drive by your car's mpg to get gallons used, then multiply by the price per gallon. For 12,000 miles at 30 mpg and $3.50 a gallon, that's $1,400 a year.

How much does gas cost per month on average?

Most US drivers spend about $100-$250 a month on gas, depending on miles driven, the car's fuel economy and local prices.

How much do I save with a more fuel-efficient car?

Going from 22 mpg to 35 mpg at 12,000 miles a year and $3.50 gas saves about $700 a year, or roughly $3,500 over five years.

Is an electric car cheaper to fuel?

Usually yes. Charging at home often costs a third to half as much per mile as gas. Use our EV vs Gas calculator to compare a specific pair.
