Practical Example

Let’s say you’re planning a 500-mile road trip with four friends in a car that averages 25 MPG, and the gas price is $3.75 per gallon.

Here’s how the Gas Road Trip Calculator would compute your costs:

• Total Gallons Needed: 500 ÷ 25 = 20 gallons
• Total Fuel Cost: 20 × $3.75 = $75.00
• Cost Per Person: $75 ÷ 4 = $18.75 per person
• Cost Per Mile: $75 ÷ 500 = $0.15 per mile

This quick calculation gives you an accurate estimate so you can easily plan your trip budget or split costs fairly among passengers.
