Global Fuel CalculatorFuel average and petrol cost calculator for Pakistan
In Pakistan almost everyone talks about fuel in terms of "average" — how many kilometres a vehicle covers on one litre of petrol. Pump readings are in litres, odometers are in kilometres, and prices are quoted per litre in rupees, so km/L is the figure that actually means something at the pump. This calculator is set up that way by default: enter the distance on your trip meter, the litres you filled, and the price you paid, and it returns your average in km/L along with the L/100km equivalent used in vehicle brochures.
Because fuel prices here are revised by the government roughly twice a month, the price field is left fully editable rather than locked to a stored rate. Put in the figure from your last fill-up and the cost per kilometre and trip estimates will reflect what you are actually paying, not a stale national average.

How fuel economy is measured here
Pakistan works in kilometres for distance and litres for fuel, with economy normally quoted as km/L. The calculator above is set that way by default, and the unit selectors let you switch if you need a different basis.
| Unit | Typical local figure |
|---|---|
| L/100km | 7.69 |
| km/L | 13.00 |
| MPG (US) | 30.58 |
| MPG (imperial) | 36.72 |
Local context
Petrol (motor spirit) and high-speed diesel are the two common road fuels, sold by the litre at pumps that display the current notified price. CNG remains in use in parts of Punjab and Sindh and is sold by the kilogram, so if you run on CNG treat "litres" as kilograms and read the result as km per kg — the arithmetic is identical, only the label changes.
A 1000cc hatchback driven mostly in city traffic typically returns somewhere in the low-to-mid teens in km/L; the same car on a motorway run will do noticeably better. Motorcycles, which do most of the country's commuting, commonly sit far higher. Those are rough bands, not promises — load, tyre pressure, air-conditioning use and Lahore or Karachi traffic all move the number.
Common questions
How do I calculate my car's average in km/L?
Fill the tank completely, reset the trip meter, drive normally, then fill completely again. Divide the kilometres shown on the trip meter by the litres it took to refill. That figure is your km/L average. Doing it over a full tank rather than a few litres removes most of the error from pump cut-off differences.
Why is my average lower than the company figure?
Manufacturer figures come from controlled test cycles with a warm engine, no air-conditioning, steady speeds and no traffic. Real driving in Lahore, Karachi or Rawalpindi involves idling, stop-start crawling and frequent acceleration, all of which consume fuel without adding distance. A gap of twenty to thirty percent between brochure and reality is normal, not a fault.
Should I use km/L or L/100km?
Use km/L for day-to-day comparison in Pakistan — it is what pumps, mechanics and other drivers use. L/100km is useful when you are comparing against imported vehicle specifications or European reviews. This calculator shows both from the same input so you never have to convert by hand.
Does the calculator handle CNG?
Yes, with one substitution. CNG is sold by the kilogram rather than the litre, so enter kilograms in the fuel field and the price per kilogram in the price field. The result reads as kilometres per kilogram and cost per kilometre, both of which are correct.
How often should I check my average?
Every few fill-ups is enough to spot a trend. A single tank can be misleading if that week happened to be unusually heavy on traffic or motorway driving. A sudden sustained drop of more than about ten percent is worth investigating — underinflated tyres, a clogged air filter and a dragging brake are the usual culprits.
Are the prices in this calculator official?
No. The price field starts with an indicative figure and is meant to be overwritten. Fuel prices in Pakistan change on a fortnightly notification cycle, so always enter the rate printed on your own receipt for an accurate cost per kilometre.
