Frequently asked questions
How much is gas for a 1,200-mile road trip?
$136.00 at 30 MPG and $3.40/gal — $45.33 per person with 3 passengers.
How do you split road trip costs fairly?
Split fuel per person (or per mile), then add tolls and parking to the shared pot. The road trip calculator does the per-person math for any distance and party size.
Does MPG matter more than gas price?
Both matter equally in the formula — gallons = miles ÷ MPG, cost = gallons × price. A 10% better MPG saves exactly as much as 10% cheaper gas.
