Mathematical Formula & Method
Fuel Cost Calculator Formula
Total Fuel = Distance / Mileage | Total Cost = Total Fuel × Price per Unit
Worked Examples & Step-by-Step Solutions
350 km trip, 14 km/L efficiency, $1.50/L price
- Total Fuel Needed: 350 / 14 = 25.0 Liters.
- Total Trip Fuel Cost: 25 × $1.50 = $37.50.
- Cost per km: $37.50 / 350 = $0.11/km.
How to Use the Fuel Cost Calculator
- Enter trip distance, vehicle fuel economy, and current gas price.
Important Assumptions & Unit Conventions
- Actual fuel consumption varies with vehicle load, traffic, speed, and terrain.
