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
Fuel Tax Impact on Car Selection
| Fuel Type | Tax Burden | Best For |
|---|---|---|
| Petrol | High excise + VAT | Low usage <10,000 km/year |
| Diesel | Lower fuel, higher car tax | High usage >15,000 km/year |
| CNG | Moderate tax | Taxi/commercial use |
| Electric | Zero fuel tax | Future-proofing |
