Calculate complete road trip expenditures, estimating fuel consumption from mileage and MPG, highway tolls, motel lodging, roadside dining, and park passes.

Transportation & Mobility Summary

Road Trip Total Cost Formula

Road Trip Total = ((Distance Miles / Vehicle MPG) * Gas Price) + Tolls + Lodging + (Daily Food * Days * Travelers) + Parks
  • Fuel Subtotal: Total driving distance divided by vehicle fuel efficiency (MPG) multiplied by average price per gallon.
  • Tolls & Transit: Anticipated turnpike, bridge, and toll highway charges.
  • Per-Mile Operating Cost: Total trip budget divided by miles driven.

Step-by-Step Worked Example

Scenario: Two friends embark on a 1,200-mile, 5-day road trip in an SUV getting 25 MPG with $3.60/gallon gas, $45 in tolls, $500 in motel lodging, and $45/person/day food.

Calculation Steps:

  1. Gallons Consumed: 1,200 / 25 = 48 gallons
  2. Fuel Cost: 48 gallons * $3.60 = $172.80
  3. Food Subtotal: $45 * 5 days * 2 travelers = $450.00
  4. Lodging & Tolls: $500.00 + $45.00 = $545.00
  5. Total Road Trip Cost: $172.80 + $450.00 + $545.00 = $1,167.80
  6. Cost Per Traveler: $1,167.80 / 2 = $583.90 ($0.97 per mile)
Result: The total road trip cost is $1,167.80 ($583.90 per traveler, or $0.97 per mile driven). Fuel accounts for $172.80 (48 gallons).

How to Use This Calculator

  1. 1Input total driving distance in miles and your vehicle average fuel economy (MPG).
  2. 2Provide current gas prices per gallon and anticipated highway toll charges.
  3. 3Add lodging and daily meal allowances to review your all-in travel budget.

Assumptions & Limitations

  • Assumes steady highway fuel efficiency across the driving itinerary.
  • Does not include vehicle wear-and-tear or oil changes unless entered manually.

Frequently Asked Questions

Is driving cheaper than flying for a family vacation?

For 3 or more travelers, driving is almost always significantly cheaper than flying for distances under 800-1,000 miles. Four round-trip airline tickets with bags often cost $1,200-$1,800, whereas driving 800 miles consumes only $100-$140 in gasoline.
