Calculate the cost of your journey
To get the most accurate figures from this calculator we recommend you use our MPG Calculator to calculate mpg. You can get an approximate figure by using the MPG your car or the manufacturer tells you though.
You can use our fuel station finder to look up current prices near your start or end point.
Calculate the cost of a journey based on distance, MPG and fuel price
Frequently Asked Questions
Divide the journey distance (in miles) by your MPG to get gallons used. Multiply by 4.546 to convert to litres, then multiply by the fuel price in pence per litre and divide by 100 to get the cost in pounds. This calculator does all of that for you.
Always use your real-world MPG for the most accurate result. Manufacturer figures are typically 20–30% higher than what you'll achieve in normal driving. Use our MPG Calculator to measure your true fuel economy.
