How is trip fuel cost calculated?

Divide the distance by your kilometres per litre to get the litres required, then multiply the litres by the price per litre. For a 300 kilometre trip at 12 kilometres per litre and 280 per litre, that is 25 litres costing 7,000. For a return journey, double the distance before you start or double the final cost.

What is the easiest way to improve fuel efficiency?

Keep tyres inflated to the recommended pressure, since under inflated tyres can cost several percent in mileage. Avoid harsh acceleration and heavy braking, maintain a steady speed, and remove unnecessary weight from the boot. Service the vehicle on schedule with clean air and fuel filters, and avoid long idling. Air conditioning increases consumption noticeably in city driving.

Does city driving really use more fuel than highway driving?

Yes, usually by a wide margin. Stop and go traffic means constant acceleration from rest, which is the most fuel hungry part of driving, plus extended idling at signals where you cover no distance at all. Highway driving at a steady moderate speed lets the engine run in its most efficient range, which is why highway figures are typically 30 to 50 percent better.

How should we split fuel costs on a shared trip?

Calculate the total fuel cost for the full journey, then divide by the number of people travelling, including the driver. If the vehicle owner is also absorbing wear, tyres, and maintenance, it is common to add a modest allowance on top. For trips where passengers join partway, split each leg separately among the people actually in the vehicle for that leg.

How it works

We multiply the one-way distance by the trip type and number of trips, divide by your vehicle's mileage to get fuel used, then multiply by the price.

Total distance = 100 km × 1 × 1 = 100 km
Fuel needed   = 100 / 12 = 8.33 L
Total cost    = 8.33 × PKR 258 = PKR 2,150
Per passenger = PKR 2,150 / 1 = PKR 2,150
CO₂ emissions = 8.33 × 2.31 kg/L = 19.3 kg

Overview

What is the Fuel Cost Calculator?

A Fuel Cost Calculator estimates how much fuel a journey will consume and what that fuel will cost at current prices. It takes the distance you plan to travel, how efficiently your vehicle uses fuel, and the price per litre, and turns those three numbers into a single figure you can budget against before setting off.

Fuel is one of the largest running costs of owning a vehicle and one of the easiest to underestimate, because it is paid in small amounts spread across the month rather than as a single visible bill. Working out the true cost of a route helps with everyday decisions: whether a daily commute is worth it, how much to charge a client for travel, how to split costs fairly on a shared trip, and whether a longer route with better roads actually costs less than a shorter route through heavy traffic.

Step-by-step

How to use this calculator

1Enter the total distance of your journey in kilometres, remembering to double it if you are calculating a return trip.
2Enter your vehicle fuel efficiency in kilometres per litre, using the real world figure from your own driving rather than the manufacturer claim.
3Enter the current price per litre of petrol or diesel at the pump you use.
4Submit to see how many litres the trip will consume and what that will cost in total.
5Adjust the efficiency figure to compare vehicles, or divide the total by the number of passengers to work out a fair cost per person.

Methodology

How it works

The calculation runs in two steps. First, the distance is divided by your fuel efficiency to find how many litres the journey needs. A 300 kilometre trip in a vehicle achieving 12 kilometres per litre requires 25 litres. Second, that litre figure is multiplied by the price per litre to give the total cost. At 280 per litre, those 25 litres cost 7,000.

Accuracy depends almost entirely on the efficiency figure you enter. Real world mileage is usually well below the published number and varies with traffic, air conditioning use, tyre pressure, load, terrain, driving style, and engine condition. The most reliable way to find your own figure is to fill the tank completely, reset the trip meter, drive normally until you refill, then divide the distance travelled by the litres it took to fill up again. Repeat this over a few tanks and use the average.
