How to Calculate Your Monthly Fuel Cost in Pakistan
Calculating your monthly petrol or diesel expense uses one simple formula: Monthly Fuel Cost = (Daily Distance ÷ Vehicle Mileage) × Fuel Price × Days Per Month.
For example: drive 50 km/day, car gives 14 km/L, petrol costs Rs. 293/L, driven 26 days/month → Rs. 27,178/month. Our petrol cost calculator does this in real-time the moment you enter your values.
Pakistan’s petrol and diesel prices change every two weeks due to international crude oil benchmarks, the PKR/USD exchange rate, and OGRA levies. Our adjustable price field means your monthly fuel cost estimate is always current — not based on an outdated default.

| Vehicle Type | Common Models | Fuel Average |
|---|---|---|
| 🏍️ Motorcycle | Honda CD70, CG125, Yamaha YBR | 40–60 km/L |
| 🚗 Small Car | Suzuki Alto, Mehran, Cultus | 16–22 km/L |
| 🚙 Family Sedan | Toyota Corolla, Honda Civic | 11–15 km/L |
| 🚗 Economy Hatch | Suzuki Swift, WagonR | 14–18 km/L |
| 🚐 SUV / Crossover | Honda BR-V, Kia Sportage | 8–12 km/L |
| 🟢 CNG Vehicle | Any CNG-converted car | 15–25 km/kg |
5 Proven Ways to Lower Your Monthly Fuel Bill
1. Keep Tyre Pressure Correct
Under-inflated tyres increase rolling resistance. Keeping pressure at the manufacturer-recommended level saves up to 3% on fuel — that’s Rs. 800–2,000/month for the average commuter.
2. Service Your Engine Regularly
A clogged air filter or worn spark plugs can cut fuel economy by 10–20%. Servicing every 5,000–8,000 km pays for itself quickly in reduced fuel costs.
3. Drive Smoothly
Aggressive acceleration and hard braking waste 15–30% more fuel. Smooth, gradual driving on highways and anticipating stops ahead of time improves your fuel average significantly.
4. Consider CNG Conversion
At roughly Rs. 150–180/kg versus Rs. 285–310/L for petrol, CNG cuts your per-km fuel cost by 50–60%. For commuters driving 40+ km daily, conversion ROI is typically under 8 months.
5. Reduce Unnecessary Idling
An idling engine burns fuel and covers zero distance. Turning off the engine when stationary for over 60 seconds — at signals, in queues, or waiting — adds up to meaningful monthly savings.

• Today’s CNG price per kg from your local station
• Your vehicle’s km per kg mileage rating
• Daily distance and days per month as usual
At roughly Rs. 150–180/kg, CNG costs 50–60% less than petrol per kilometre. For a 40 km daily commuter, switching to CNG can save over Rs. 12,000–15,000 per month.
WhatsApp opens with a pre-written message that includes your complete breakdown — daily, weekly, monthly and annual fuel costs — ready to send to any contact, family group, or saved to yourself for record-keeping.
• Petrol (14 km/L, Rs. 293/L): ≈ Rs. 21,629/month
• CNG (18 km/kg, Rs. 160/kg): ≈ Rs. 9,244/month
That’s a saving of roughly Rs. 12,385/month or Rs. 148,620/year. CNG conversion typically costs Rs. 40,000–80,000, meaning it pays back within 3–7 months for daily commuters.
