• Gas price per gallon
• Whether the trip is one way or round trip

But this version goes much further. Your calculator includes:

• Trip cost estimation
• Split gas cost calculation
• Fuel efficiency comparison for two vehicles
• Trip planning assistant with estimated arrival time

This combination makes your tool a complete trip-management resource.

How the Travel Gas Calculator Works

Here is a simplified explanation of the main functions behind this calculator.

1. Gas Consumption Calculation

Gallons Needed = Total Distance ÷ Vehicle MPG
Total Cost = Gallons Needed × Gas Price
Cost Per Mile = Total Cost ÷ Total Distance

2. Splitting Cost with Driver Discount

Driver Discount Amount = (Total Cost × Discount %) ÷ 100
Adjusted Total = Total Cost – Discount Amount
Cost Per Person = Adjusted Total ÷ Number of People
Driver Pays = Cost Per Person + Discount Amount

3. Vehicle Comparison

Vehicle 1 Cost = (Distance ÷ MPG1) × Gas Price
Vehicle 2 Cost = (Distance ÷ MPG2) × Gas Price
Savings = |Vehicle 1 Cost – Vehicle 2 Cost|

4. Arrival Time Estimation

Driving Hours = Distance ÷ Speed
Total Minutes = Driving Minutes + Rest Stop Minutes
Estimated Arrival = Departure Time + Total Minutes
