How to Use the Fuel Cost Calculator

This calculator uses a straightforward formula: Fuel Cost = (Distance ÷ Mileage) × Fuel Price. Here is what each field means:

Real-World vs Claimed Mileage

ARAI (Automotive Research Association of India) lab-tested mileage figures are always higher than real-world figures. For accurate calculations, use these real-world estimates:

Tips to Improve Fuel Economy

Proper tyre inflation (check the owner's manual for recommended PSI) can improve mileage by up to 3%. Driving at a steady 60–80 km/h on expressways saves 15–20% fuel compared to maintaining 110–120 km/h. Avoiding hard braking and unnecessary idling further stretch each litre.

Frequently Asked Questions

How is fuel cost calculated?+

Fuel cost = (Distance ÷ Fuel Efficiency) × Fuel Price per litre. For example, a 500 km trip in a car that gives 15 km/L at ₹102/L costs (500 ÷ 15) × 102 = ₹3,400 in fuel.

What is the average mileage of Indian cars?+

Mileage varies by car type. Hatchbacks like Maruti Swift give 20–23 km/L (claimed) but 14–17 km/L real-world. Sedans average 13–17 km/L, SUVs 10–14 km/L, and diesel cars typically give 18–24 km/L claimed. Always use your real-world average for accurate results.

What is the current petrol price in India?+

Petrol prices vary by city due to local taxes. As of mid-2025, petrol is around ₹94–106/L in major metros. Diesel is typically ₹8–12 cheaper per litre. Check your local petrol station or fuel price apps for today's rate.

Does driving speed affect fuel cost?+

Yes, significantly. Most Indian cars achieve peak fuel efficiency between 60–80 km/h. Highway driving at 100–120 km/h can reduce mileage by 15–25% compared to the claimed figure. AC usage reduces mileage by another 8–12%. Account for this in your estimates.

How can I reduce my fuel cost on a long trip?+

Maintain steady speeds (60–80 km/h on highways), keep tyre pressure correct (check before long trips), avoid unnecessary idling, travel in the cooler parts of the day to reduce AC load, and ensure the car is serviced (clean air filter, fresh spark plugs all help).

Should I include return journey fuel cost?+

If you are entering one-way distance, multiply the result by 2 for a return trip. The calculator computes fuel for the distance you enter, so enter total round-trip distance for a full estimate.
