How It Works
How to Estimate Road Trip Cost
Add up fuel, tolls, lodging, and food expenses for the full trip.
Formula
Fuel = Total Miles / MPG x Gas Price
Total = Fuel + Tolls + (Hotel Nights x Rate) + (Days x Food Budget)
Worked Example
800-mile round trip, 28 MPG, $3.50/gal, $30 tolls, 2 nights at $120, $50/day food, 3 days.
total_miles = 800mpg = 28gas_price = 3.5tolls = 30hotel_nights = 2hotel_rate = 120daily_food = 50trip_days = 3
- 01Fuel = 800 / 28 x $3.50 = $100.00
- 02Tolls = $30.00
- 03Lodging = 2 x $120 = $240.00
- 04Food = 3 x $50 = $150.00
- 05Total = $100 + $30 + $240 + $150 = $520
