The Two-Step Fuel Formula
Litres needed = Distance (km) ÷ Vehicle Fuel Average (km/L)
Trip Cost (Rs.) = Litres needed × Price per litre (Rs.)
Car averages are based on standard highway driving. For exact city vs highway measurement, use the fuel average calculator.
How to Calculate Fuel Cost for a Trip
You can figure out the fuel cost for any trip in two steps:
Example: A 1300cc car (14.5 km/L) driving Lahore to Islamabad (378 km) needs 378 ÷ 14.5 = 26.1 litres. At today's price of Rs. 377.71 per litre, that is Rs. 9,860 (rounded to nearest Rs. 10).
With AC on, the average drops by about 12% (14.5 → 12.76 km/L), so the same trip needs about 29.6 litres. For a return trip, double the litres and the cost.
Petrol Cost per km by Car Type
A quick way to estimate fuel cost for travel is to know how much petrol your car uses for every 100 km. Multiply the litres by today's price to get the cost, or divide the price by your km/L to get the cost per km.
| Car class | Typical average | Petrol per 100 km | Cost per km (Live) |
|---|---|---|---|
| 660cc (Alto, Mira) | 19.5 km/L | 5.1 L | Rs. 19.37 |
| 1000cc (Cultus, Vitz) | 16.5 km/L | 6.1 L | Rs. 22.89 |
| 1300–1500cc (City, Yaris) | 14.5 km/L | 6.9 L | Rs. 26.05 |
| 1800cc (Civic, Corolla) | 12 km/L | 8.3 L | Rs. 31.48 |
| SUV / Crossover | 10.5 km/L | 9.5 L | Rs. 35.97 |
| Diesel 4x4 (Fortuner, Revo) | 9.5 km/L | 10.5 L | Rs. 41.44 |
| Hybrid (Prius, Aqua) | 21 km/L | 4.8 L | Rs. 17.99 |
| Motorcycle (CD70, CG125) | 45 km/L | 2.2 L | Rs. 8.39 |
Averages are the calculator's default values for highway driving. Your real average may be different; find it with the fuel average calculator.

What Changes Your Fuel Cost?
Adds about 10% more fuel in this calculator due to engine compressor load.
On motorways, 90–100 km/h usually uses less petrol than high-drag 120 km/h.
Stop-start urban congestion consumes significantly more petrol than steady highway cruising.
A full car and heavy boot luggage lower your vehicle's effective kilometre per litre.
Underinflated tyres, a clogged air filter or degraded engine oil noticeably raise fuel use.
Selecting a round trip doubles the total distance, required litres and final petrol expenditure.

Where Our Numbers Come From
Petrol and diesel prices come from official OGRA notifications and are updated when a new price is announced. Car averages are typical highway values that you can change. The carbon estimate uses about 2.3 kg of CO₂ per litre of petrol burned. Last updated: April 2026.
