Trip fuel cost
Estimate fuel cost from distance, fuel economy, and price per liter.
When to use this calculator
Calculate trip fuel cost, actual fuel economy, and estimated driving range from fuel price, usage, or budget.
- Planning a road-trip fuel budget
- Checking real-world efficiency after refueling
- Estimating range from available money
Worked examples
Trip cost
120 km at 12 km/L and KRW 1,700/L costs about KRW 17,000.
Actual efficiency
450 km using 35 L is about 12.86 km/L.
Budget range
KRW 50,000 at KRW 1,700/L and 12 km/L gives about 353 km.
Frequently asked questions
Does the estimate include tolls?
No. It only estimates fuel cost.
Why does actual economy differ from the official rating?
Traffic, temperature, tires, speed, idling, and air conditioning all affect it.
Should I enter one-way or round-trip distance?
Enter the full distance you expect to drive.
How to interpret the result
Fuel prices and real efficiency change, so leave a margin in travel budgets.
Do not rely on a calculated maximum range when the fuel warning light is on.
