Fuel Cost Calculator — Petrol & Diesel Trip Cost

What is a Fuel Cost — Petrol & Diesel Trip Cost?

Fuel cost is one of the largest recurring expenses for Pakistani households with a vehicle. With petrol and diesel prices changing monthly and averaging PKR 250–300+ per litre, calculating the true cost of driving is essential for personal budgeting and business planning. Fuel efficiency (commonly called mileage in Pakistan) describes how many kilometers your vehicle travels per litre of fuel — higher is better and means lower cost per kilometer. The fuel cost formula is straightforward: Fuel Cost = (Distance ÷ Fuel Efficiency) × Price per Litre. However, the cumulative impact over a monthly commute or annual driving is often surprising. A daily 30km commute in a car getting 12 km/litre at PKR 280/litre costs approximately PKR 16,800 per month — a significant household expense that many people underestimate.

How to Use This Calculator

Enter your trip distance in kilometers. Enter your vehicle's fuel efficiency in km per litre — check your car manual or calculate it by filling the tank, driving normally, then calculating km driven divided by litres to refill. Enter the current fuel price per litre in PKR (or your selected currency). Select the trip type: one way, return trip, monthly commute (22 working days × 2), or annual commute. Click Calculate to see total fuel cost, total litres needed, cost per km, and total distance.

💡 Pro Tips

• ✓Pakistan average car fuel efficiency: 10–14 km/litre. Motorcycles: 35–50 km/litre.
• ✓Driving at 80–90 km/h gives the best fuel economy — highway speeds above 110 km/h reduce efficiency significantly.
• ✓Tyre pressure affects fuel efficiency by up to 3% — keep tyres inflated to the recommended PSI.
• ✓Air conditioning reduces fuel efficiency by 10–15% in city driving — factor this into calculations for summer.
• ✓Fuel price in Pakistan changes monthly — update the price field to get accurate current costs.
• ✓Carpooling with just one colleague halves your commute cost immediately.
