Understanding Fuel Cost Calculations
Calculating fuel costs for your trip involves key factors: distance, vehicle fuel efficiency (mileage), and current fuel price. Our calculator uses the formula: Fuel Required = Distance ÷ Mileage, and Total Cost = Fuel Required × Fuel Price.
For example, a 300 km trip in a car with 15 km/l efficiency and petrol at ₹100/liter needs 20 liters costing ₹2,000 total, with ₹6.67 per kilometer cost.
Petrol vehicles offer good performance but higher costs. Diesel vehicles provide better mileage for long trips. CNG vehicles are most economical with lower per-kilometer costs.
Tips to Reduce Fuel Costs
- Maintain proper tire pressure to improve fuel efficiency by up to 3%
- Remove excess weight – every 100 kg increases consumption by 6-8%
- Use AC wisely – open windows at low speeds, AC at highway speeds
- Plan routes to avoid traffic and reduce idle time
- Regular maintenance including oil changes and air filter replacement
- Drive smoothly with gradual acceleration and braking
