Trip & Vehicle Parameters
Total Cost: $70.00
Distance: 500 miles (804.7 km) | Fuel: 20 gal (75.71 L)How to Calculate Fuel Cost for a Road Trip
To calculate the fuel cost of any journey:
Example: A 500-mile trip in a car that gets 25 miles per gallon with gas priced at $3.50 per gallon:500 ÷ 25 = 20 gallons of gas × $3.50 = $70.00 total fuel cost.

Fuel Cost Calculator — Frequently Asked Questions
Q1 How do I calculate fuel cost for a road trip? ▾
Divide your total trip mileage by your vehicle’s miles per gallon (MPG) to determine how many gallons of gas you need, then multiply that by the gas price per gallon.
Q2 How do I convert between MPG and L/100 km? ▾
To convert L/100 km to US MPG, divide 235.214 by the L/100 km value. Formula: MPG = 235.214 ÷ (L/100 km).
Q3 What is the most effective way to improve vehicle fuel economy? ▾
Driving at steady highway speeds (between 55–65 mph), avoiding rapid acceleration and hard braking, maintaining proper tire pressure, and removing unnecessary cargo can improve fuel efficiency by 15% to 30%.
