How Fuel Cost Calculator Works: Mathematical Formula & Steps

Calculates total road trip fuel expenditure and volumetric gas consumption in both metric (liters) and imperial (gallons).

Journey Fuel Expense & Consumption Equation
Fuel Cost = ( Distance ÷ 100 ) × ( L/100km ) × Price per Liter
Where:
  • Distance (Trip Kilometers / Miles): Total one-way or round-trip driving distance.
  • Economy (Fuel Efficiency): Fuel rating in Liters per 100 km (L/100km) or Miles per Gallon (MPG).
  • Price (Pump Price): Price per liter or gallon of fuel.

Worked Real-World Example: Step-by-Step Calculation

To illustrate how the fuel cost calculator works in practice, consider the following real scenario:

350 km Journey in a Car Consuming 7.5 L/100km at $1.65/Liter

Scenario: Trip distance = 350 km, fuel economy = 7.5 L/100km, gas price = $1.65/L.

Step 1: Calculate liters required
(350 ÷ 100) × 7.5 = 26.25 Liters
Step 2: Multiply by pump price
26.25 L × $1.65/L = $43.31
Final Result: Total fuel required is 26.25 liters costing $43.31 ($0.12 per km).

Key Takeaways & Best Practices

  • Aggressive highway speeding (above 110 km/h or 70 mph) increases aerodynamic drag and lowers fuel efficiency by 15% to 25%.

Frequently Asked Questions

How do you convert MPG to L/100km?

To convert US MPG to Liters per 100 km: L/100km = 235.215 ÷ US MPG. For example, 30 MPG US equals 235.215 ÷ 30 = 7.84 L/100km.
