Trip details

✅ Inputs

One-way distance. Enable round trip if needed.

If enabled, distance is doubled automatically.

Pick the unit you know; we’ll convert internally.

We calculate cost using your selected currency and unit.

Tolls, parking, snacks — added to “Total trip cost”.

Useful for AC, traffic, hills, heavy load.

Core Formula: Fuel Used = Distance ÷ Mileage (or Distance × L/100km ÷ 100).
Then Fuel Cost = Fuel Used × Fuel Price. Add optional extras for total trip cost.

Explanation

This Fuel Cost Calculator estimates the cost of fuel for your trip using distance, fuel efficiency (mileage), and fuel price. You can choose km/L, L/100 km, or MPG units, and optionally add a safety buffer for traffic, AC, hills, or heavy load.

Tip: Use your realistic mileage (not the brochure value). For long highway trips, mileage is usually better than city driving.

Formula

Fuel Used (L) = Distance (km) / Mileage (km/L)
Fuel Used (L) = Distance (km) × (L/100km) / 100
Fuel Cost = Fuel Used × Fuel Price
