Road Trip Cost Estimator — Formula
## Road Trip Fuel Cost
Knowing your fuel costs in advance helps budget for road trips and compare driving vs flying.
### Formula
**Gallons Needed = Distance / MPG**
**Total Cost = Gallons x Gas Price**
**Cost per Person = Total Cost / Passengers**
Road trips become more cost-effective with more passengers. A 500-mile trip at 28 MPG and $3.50/gallon costs about $62.50 total, or just $31.25 split two ways.

Exemplo Resolvido
A 500-mile trip in a 28 MPG car at $3.50/gallon with 2 passengers.
- Gallons = 500 / 28 = 17.86 gallons
- Total cost = 17.86 x $3.50 = $62.50
- Per person = $62.50 / 2 = $31.25
- Cost per mile = $3.50 / 28 = $0.125/mile
