TopToolsAiCalculate how much fuel a trip will use and what it will cost, based on distance, your vehicle's mileage, and the current fuel price per litre. A 300km trip in a car that does 12km per litre, with fuel at PKR 280 per litre, burns 25 litres and costs PKR 7,000 — handy to check before committing to a long drive.

Frequently asked questions
What if my car's mileage varies by driving conditions?
Use your average real-world mileage (from past fill-ups) rather than the manufacturer's rated figure for a more realistic estimate.
Does this account for fuel price changes mid-trip?
No — it uses a single price you enter. For long trips with price changes, calculate each leg separately.
How do I find my actual mileage (km/l)?
Divide the kilometers driven since your last full tank by the liters used to refill it — do this over a few tanks for a more reliable average.
Can I use this for a round trip?
Yes — just enter the total round-trip distance rather than the one-way distance.
