Gas & Road Trip Split Calculator
Calculate the exact fuel cost for any road trip and split it fairly between passengers. Enter distance, gas price, and your car's MPG to get the fuel cost. Add tolls and parking, choose whether the driver gets a discount for wear and tear on their car, and see what each person owes.
To split gas costs for a road trip, divide the total distance by your car's MPG, multiply by the gas price, then divide by the number of passengers. For a 300-mile trip at 25 MPG with $3.50 gas and 4 people: 12 gallons × $3.50 = $42 ÷ 4 = $10.50 each. Add tolls and parking below.
