How to use the fuel cost calculator.
Calculate and review
Use the main action when needed. Choose miles with UK MPG or kilometres with litres per 100 km; both are converted to litres for the cost.
Try a worked example
For UK MPG, litres used = miles ÷ MPG × 4.54609 before multiplying by price per litre.
Check the assumptions
Traffic, weather, load, driving style and pump prices make actual fuel use vary.
