Diesel Cost Per Mile

Calculate diesel cost per mile.

Calculate your diesel cost per mile

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

What your result means

This estimates diesel fuel cost per mile from the diesel 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: 150p/litre and 50 UK MPG.

Diesel cost per mile
13.64p
Cost per 100 miles
£13.64

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 50 UK MPG by diesel price

140p/litre12.73p
150p/litre13.64p
160p/litre14.55p

Helpful questions

What does diesel cost per mile mean?

It is the estimated fuel spend for each mile based on the inputs. It excludes insurance, tax, servicing and depreciation.

How does MPG affect the estimate?

Higher UK MPG means fewer litres are used per mile, reducing the estimated fuel cost. Use the MPG Calculator to measure your real figure.

Why can actual cost differ?

Actual MPG and pump prices vary with driving conditions and where or when you buy fuel.
