How Fuel Cost per Kilometer Calculator Works?
This tool works by multiplying your vehicle's fuel consumption in liters per kilometer by the price per liter. The tool reads consumption in liters per 100 kilometers (L/100km), the standard metric rating.
Enter the price per liter
Type the local pump price per liter. $1.65 per liter equals $6.25 per US gallon.
Enter the L/100km rating
Type the consumption figure from the vehicle manual or dashboard. 7.8 L/100km equals 30.2 miles per gallon (MPG).
Read the cost per km
The tool divides L/100km by 100 to get liters per km, then multiplies by the price.
Apply the result
Multiply cost per km by any distance. 500 km at $0.13 per km costs about $64.
Fuel Cost per Kilometer Calculator Formula
The formula is Cost per km = (L/100km ÷ 100) × Price per Liter.
Cost per km = (L/100km ÷ 100) × Price per LiterFormula variables
- L/100km
- Liters of fuel the vehicle burns every 100 kilometers (62.1 miles).
- Price per Liter
- Pump price for 1 liter (0.264 US gallons) of fuel.
Worked example
- Fuel Price per Liter: $1.65/L
- Consumption (L/100km): 7.8 L/100km
- Divide 7.8 L/100km by 100: 0.078 liters per km.
- Multiply by $1.65: 0.078 × $1.65 = $0.1287, shown as $0.13 per km.
- Convert to miles: $0.1287 × 1.609 = $0.207 per mile.
Result: $0.13 ($/km)
Lower L/100km values mean better efficiency, the reverse of MPG. A 5.0 L/100km car costs 36% less per km than a 7.8 L/100km car at the same fuel price.
Fuel Cost per Kilometer Calculator Conversion Table
The table shows cost per km for 5 fuel prices and 4 consumption ratings.
Rows: Fuel Price per Liter ($/L). Columns: Consumption (L/100km) (L/100km). Cells: $/km.
| $/L | 5 L/100km | 6.5 L/100km | 7.8 L/100km | 10 L/100km |
|---|---|---|---|---|
| $1.20/L | $0.06 | $0.08 | $0.09 | $0.12 |
| $1.45/L | $0.07 | $0.09 | $0.11 | $0.15 |
| $1.65/L | $0.08 | $0.11 | $0.13 | $0.17 |
| $1.90/L | $0.10 | $0.12 | $0.15 | $0.19 |
| $2.10/L | $0.11 | $0.14 | $0.16 | $0.21 |
At $2.10 per liter, a 10 L/100km SUV costs $0.21 per km, twice the fuel cost of a 5 L/100km compact.
What is Fuel Cost per Kilometer Calculator?
The Fuel Cost per Kilometer Calculator is a metric tool that returns the fuel cost of driving 1 kilometer. The calculator suits drivers in Canada, the United Kingdom (UK), Europe, Australia, and Asia, where fuel sells by the liter.
Metric countries rate vehicles in liters per 100 kilometers (L/100km) rather than miles per gallon (MPG). The tool uses those native units, so no conversion step is needed.
The output works in any currency. Enter the price in euros, pounds, or rupees, and the result appears in the same currency per kilometer.
What are the uses of Fuel Cost per Kilometer Calculator?
There are 4 main uses of the Fuel Cost per Kilometer Calculator: budgeting metric road trips, pricing taxi and courier work, comparing rental cars abroad, and claiming business kilometers.
Budgeting metric road trips
Travelers in Europe or Australia multiply cost per km by route length to set a fuel budget.
Pricing taxi and courier work
Drivers paid per kilometer subtract fuel cost per km to see net income.
Comparing rental cars abroad
Tourists compare a 5 L/100km hatchback with an 8 L/100km SUV before booking.
Claiming business kilometers
Employees check whether a per-km allowance covers the real fuel cost.
