How Cost per Kilometer Calculator Works
This tool works by dividing fuel cost by kilometers driven, or by multiplying the price per liter by liters per 100 kilometers (L/100 km) and dividing by 100.
- Step 1
Choose the method
Use recorded spending and kilometers, or use price per liter and L/100 km.
- Step 2
Enter spending and kilometers
Type total fuel spending and the odometer distance in kilometers (km).
- Step 3
Or enter price and consumption
Type the price per liter and the L/100 km rating.
- Step 4
Read the cost per km
The calculator shows cost per km, cost per 100 km, and cost per 1,000 km in any currency.
Cost per Kilometer Calculator Formula
The formula divides fuel cost by kilometers driven.
Cost per km = Total Fuel Cost ÷ Kilometers Driven
Cost per km = Price per Liter × L/100 km ÷ 100
- Price per Liter
- = fuel price in any currency per liter
- L/100 km
- = liters burned every 100 kilometers
Worked Example
- A driver in Spain pays €1.79 per liter and drives a car using 6.8 L/100 km (34.6 MPG).
- Cost per km = €1.79 × 6.8 ÷ 100 = €0.122 per km.
- Cost per 100 km = €12.17.
- A 820 km (510 mi) month costs €12.17 × 8.2 = €99.81.

What is a Cost per Kilometer Calculator?
A Cost Per Kilometer Calculator is a metric unit cost tool that divides fuel cost by kilometers driven.
Most countries measure distance in kilometers and fuel in liters. The Cost Per Kilometer Calculator works natively in those units and in any currency: euros, pounds, rupees, rand, or dollars. The result supports the same decisions as cost per mile in the United States.
Company car policies in Europe, Australia, and Asia often reimburse per kilometer, so the per-km fuel figure is the number to check.
What are the uses of a Cost per Kilometer Calculator?
There are 4 main uses of the Cost Per Kilometer Calculator, including metric trip pricing, per-km allowances, and car comparison abroad.
Price trips in kilometers
Multiply route kilometers by cost per km.
Check per-km allowances
Compare an employer’s per-km rate with real fuel cost.
Compare cars in metric markets
