Annual Fuel Cost Calculation

For a car traveling 15,000 km/year with mileage of 15 km/l:

  • Fuel required: 1,000 litres
  • Petrol cost (Delhi): Rs 1,10,000/year
  • Petrol cost (Mumbai): Rs 1,17,000/year
  • Annual difference: Rs 7,000 just from fuel tax

Diesel vs Petrol: Tax Considerations

Diesel vehicles offer better mileage but face higher road tax:

  • Diesel price: Lower per litre than petrol
  • Road tax: Higher for diesel vehicles in some states
  • Initial cost: Diesel cars cost more than petrol
  • Break-even: Typically 50,000-80,000 km

Electric Vehicle: Zero Fuel Tax

EVs eliminate fuel tax entirely:

  • Charging cost: Rs 0.80-1.50 per unit (kWh)
  • No petrol/diesel: No excise or VAT
  • Annual savings: Rs 80,000-1,50,000 for high-usage vehicles

CNG Vehicles: Lower Tax Alternative

CNG offers an intermediate tax advantage:

  • Lower fuel price: Rs 75-80/kg
  • Better mileage: 20-25 km/kg
  • Lower running cost: 30-40% cheaper than petrol
