Using the current gas prices from over 80,000 retail stations Cost2Drive.com can calculate how much it will cost you to drive from one location to another, which can be helpful when planning your trip.

The newly launched site will calculate your gas milage and need for refilling to determine your total estimated cost. You can then compare this cost to the cost of flying, and decide which route would be better for you.

You’ll need to keep in mind, though, that your actual gas cost won’t be the only thing you have to factor in. You’ll need to consider the cost of food and lodging when you make your final determination. Still, it’s a helpful site, that should only get better with time.
