About the Road Trip Cost Calculator
A road trip budget starts with fuel and adds lodging, food, and tolls. This estimates the total from your distance, mileage, and gas price, then splits it evenly among travelers.
How it’s calculated
Fuel = distance ÷ mpg × price. Total = fuel + lodging + food + tolls. Per person = total ÷ travelers.
Example calculation
An 800-mile round trip at 28 mpg with $3.50 gas is about $100 in fuel before lodging and food.
Frequently asked questions
Should I use one-way or round-trip distance?
Enter the full round-trip distance so the fuel estimate covers getting home too. Add any local driving at your destination if it's significant.
How is the per-person cost figured?
The total is divided evenly by the number of travelers. Adjust the lodging and food figures to match how you actually share expenses.
