Road Trip Fuel Cost Calculator
Planning a drive or a cruise with the crew? Estimate the gas cost in seconds and split it fairly across everyone in the car.
How to estimate gas cost for a trip
The math is simple: gallons = distance ÷ MPG, then cost = gallons × price per gallon. For a 300-mile drive in a car that averages 28 MPG with gas at $3.50/gal, that's about 10.7 gallons and roughly $37.50 in fuel.
Real-world economy is usually a little below the EPA sticker, especially loaded up with people and gear or driven hard through the canyons — so pad the estimate slightly if you want to be safe. Toggle round trip to double the distance automatically, and split the total to settle up fairly with everyone riding along.
Once you're on the road, Ryvve records the actual drive with GPS — distance, route, and stats — so you can compare the real numbers to your estimate and keep a log of every trip.
Frequently Asked Questions
Divide the total trip distance by your car's fuel economy (MPG) to get the gallons of gas you'll burn, then multiply by the price per gallon. This calculator does it instantly and can double the distance for a round trip and split the total across everyone in the car.
