Fuel Cost Calculator (KM) — Know Your Exact Petrol/Diesel Cost Per Kilometre

Wondering how much petrol or diesel your next trip will actually cost — whether it’s a 15 km office commute or an 800 km highway drive? Our Fuel Cost Calculator (KM) gives you an instant, accurate answer. Just enter your distance in kilometres, your vehicle’s mileage (km per litre), and the current fuel price in your city — the calculator does the rest in real time.

This tool is built specifically around how Indian and South Asian drivers plan trips: by distance in kilometres rather than miles, and by per-litre pricing rather than per-gallon. That’s why it directly answers real questions people search for every day, such as “1 km petrol price”, “300 km how much petrol”, or “22 km me kitna petrol lagta hai”.

How the Calculation Works

Fuel Cost = (Distance in KM ÷ Vehicle Mileage in km/l) × Current Fuel Price per Litre

For example, if you’re driving 300 km in a car that gives 15 km/l mileage, and petrol costs ₹100/litre, your fuel cost = (300 ÷ 15) × 100 = ₹2,000. If diesel costs ₹90/litre and your car gives 20 km/l, the same 300 km trip costs (300 ÷ 20) × 90 = ₹1,350.

Why This Matters

Knowing your exact per-km fuel cost helps you budget for road trips, compare petrol vs diesel vehicles before buying, split fuel costs fairly in carpools, and decide whether a cab, your own car, or public transport is cheaper for a given distance.

You can use this calculator for any distance — from a quick 1 km, 2 km, or 10 km local errand to long-distance drives of 500 km, 800 km, or 2,200+ km. Simply update the distance field and the tool recalculates instantly, with no page reload needed.
