Campervan Fuel Cost Calculator (UK MPG)

Estimate campervan fuel use and cost from mileage, UK mpg and pounds per litre. See the formula and a worked example.

How to estimate campervan fuel cost

Divide miles by UK mpg to get imperial gallons. Multiply by 4.54609 for litres, then multiply by the fuel price per litre for an estimated cost. The calculator starts with an example price of £1.50 per litre. Replace it with your own price.

Worked example

A 45-mile drive at 28 UK mpg uses about 7.3 litres. At £1.50 per litre that comes to about £10.96, calculated before rounding the litres. If a return trip takes the same route, enter 90 miles for the total.

Use fuel economy from a similar journey if you have it. Hills, load, speed and traffic can change actual fuel use.
