Road Trip Cost Calculator: Gas, Hotels, Food, and Fun

Road trips offer freedom and flexibility, but costs add up quickly. Gas, hotels, food, and unexpected expenses can turn a budget trip into a financial stretch. This guide breaks down every road trip cost category and shows how to calculate your total before you leave.

Gas Costs

Formula: (Total Miles / MPG) x Price Per Gallon

Example: 2,000 miles in a 28 MPG car, gas at $3.50

  • Gallons: 71.4
  • Cost: $250

Add 15% for city driving, detours, and idling.

Road trips can be cheap or expensive depending on choices. A camping trip with home-cooked meals costs a fraction of a hotel-and-restaurant trip. Use our calculator to model both and pick what fits your budget.
