Compare energy costs using your real daily distance, petrol price, vehicle mileage, EV efficiency and electricity rate. The calculator shows monthly savings and how long a higher purchase price may take to recover.
How to Calculate Vehicle Fuel Cost in Pakistan
Estimate trip and monthly fuel expense using measured mileage, distance and current pump price.
Read the complete guide →How to use it
- 1
Estimate your normal daily distance rather than using a single long trip.
- 2
Enter real-world petrol mileage and the fuel price you currently pay.
- 3
Compare monthly energy expense, then account separately for purchase price and battery replacement.
Formula and methodology
Petrol cost = distance ÷ mileage × petrol price. EV cost = distance × kWh/km × electricity rate.
Uses distance, efficiency, price and ownership assumptions entered by the user. Actual performance depends on route, vehicle condition and changing prices.
Worked calculation example
At 50 km daily, a 40 km/litre bike uses 37.5 litres monthly. Compare that with the electricity needed by the selected EV efficiency.
How to interpret your result
Compare monthly petrol and electric vehicle running costs and estimate your payback period. Read the main result together with the supporting values rather than treating one number as a guarantee. The disclosed method is: Petrol cost = distance ÷ mileage × petrol price. EV cost = distance × kWh/km × electricity rate.

Scenario comparison
| Scenario | What it demonstrates |
|---|---|
| Worked baseline | At 50 km daily, a 40 km/litre bike uses 37.5 litres monthly. Compare that with the electricity needed by the selected EV efficiency. |
| Driving conditions check | Congestion, speed, load and terrain change petrol and electric efficiency. |
| Charging source stress test | Grid tariff, off-peak charging and solar power create different electricity costs. |
Common mistakes to avoid
- Ignoring driving conditions: Congestion, speed, load and terrain change petrol and electric efficiency.
- Overlooking charging source: Grid tariff, off-peak charging and solar power create different electricity costs.
- Failing to test ownership costs: Maintenance, financing, insurance and resale value may outweigh energy savings.
Verify the inputs using fuel receipts, measured distance, manufacturer specifications and current official prices where applicable.
What can affect the result?
Driving conditions
Congestion, speed, load and terrain change petrol and electric efficiency.
Charging source
Grid tariff, off-peak charging and solar power create different electricity costs.
Ownership costs
Maintenance, financing, insurance and resale value may outweigh energy savings.
Limits of this estimate
The quick comparison uses a fixed EV energy assumption and does not model a specific vehicle, charger losses, battery ageing or financing.

Frequently asked questions
Is the EV versus petrol calculator free?＋
Yes. SolvePilot tools are free, work in your browser, and require no account.
Does SolvePilot store my values?＋
No. Calculations run locally in your browser and the values you enter are not sent to a server.
Should I treat the result as an exact bill or quotation?＋
No. Results are informed estimates. Final charges can vary because of taxes, tariffs, lender terms, usage patterns, or provider rules.
How can I improve the accuracy?＋
Use recent values from your own bill, statement or institution, review every assumption, and confirm important results with the relevant official source.
Does this include battery replacement?＋
The primary result compares energy expense. Purchase difference and optional maintenance allowance are included separately; long-term battery replacement should also be considered.
