Petrol Cost Per Mile

Calculate petrol cost per mile.

Calculate your petrol cost per mile

Enter your price and MPG to estimate petrol cost per mile.

What your result means

This estimates petrol fuel cost per mile from the petrol price per litre and UK MPG you enter. Better MPG or a lower entered fuel price reduces the estimated fuel-only cost.

Worked example

Example only: 142p/litre and 45 UK MPG.

Petrol cost per mile
14.35p
Cost per 100 miles
£14.35

This represents fuel cost only, not total vehicle ownership cost.

Formula

p/mile=Price (p/litre)×4.54609UK MPG\text{p/mile}=\frac{\text{Price (p/litre)}\times4.54609}{\text{UK MPG}}

Cost at 142p/litre by UK MPG

UK MPGp/mile
3021.52p
4016.14p
5012.91p
6010.76p
