How to use it
A quick estimate, without the spreadsheet.
Inputs and units
Enter miles driven, imperial miles per gallon and pump price in pence per litre.
Formula
Litres = miles / imperial MPG × 4.54609. Cost in pounds = litres × pence per litre / 100.
Worked example
100 miles at 50 imperial MPG uses about 9.09 litres; 150p per litre gives approximately £13.64.
Assumptions and limitations
Uses imperial gallons, not US gallons. Pump-price defaults are illustrative. Actual consumption depends on roads, traffic, driving style and vehicle load.
