Fuel Cost Calculation Methods
Accurate Fuel Costing
Our calculator uses the following formula to determine fuel costs:
Fuel Cost = (Distance ÷ MPG) × (Fuel Price per Litre × 4.546)
The factor 4.546 converts litres to gallons, as fuel is sold by the litre but efficiency is measured in miles per gallon.
Factors Affecting Fuel Consumption
Driving Conditions
Motorway driving typically offers better fuel efficiency than city driving due to consistent speeds and fewer stops.
Vehicle Maintenance
Well-maintained vehicles with proper tyre pressure and recent services achieve optimal fuel efficiency.
Driving Style
Smooth acceleration and braking, maintaining steady speeds, and anticipating traffic can improve MPG by up to 15%.
