Fuel consumption and trip cost
Estimate fuel and trip cost from distance, consumption and your entered fuel price.
Your inputs
The editable example is illustrative. Enter your own dimensions, operating data, prices, and fees. Results update as you edit.

How it works
- Fuel volume = (km) × (L/km); Fuel-only trip cost = Fuel volume (L) ÷ (L) ×
- Worked example: 300 km × 6/100 = 18 L; 18 × 1.50 = 27; 27/3 = 9
- Supported input limits: : 0 ≤ x ≤ 1,000,000,000,000; : 1e-12 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000; : 1 ≤ x ≤ 1,000
