Results
- Fuel required23.68 L
- Estimated fuel cost$29.60
Formula
Fuel used (L) = distance (km) × consumption (L/100km) ÷ 100; trip cost = fuel used × fuel price.

How this formula works
Fuel cost estimation translates route distance into expected liters consumed, then multiplies by current unit fuel price. It is a practical model for trip budgeting and route comparison.
Real outcomes vary with speed, load, traffic, terrain, and weather. Use this result as a planning estimate and add a safety margin when budgeting high-variability trips.
