Fuel Cost Calculator: How to Calculate Car Fuel Consumption
Fuel economy is one of the top concerns for car owners. Knowing your car's real fuel consumption helps you plan driving budgets better.
Fuel Consumption Formula
Fuel Consumption (L/100km) = Fuel Used (L) ÷ Distance (km) × 100
Cost Per Kilometer
Cost/km = Fuel Consumption × Fuel Price ÷ 100
Example: 8L/100km at $1.2/L = $0.096/km
Factors Affecting Fuel Economy
1. Driving habits: rapid acceleration increases consumption; 2. Traffic: city driving uses 30%-50% more; 3. Load: every 100kg adds ~5%; 4. Tire pressure: under-inflated tires increase rolling resistance; 5. AC use: adds 10%-20%.
