Fuel Cost
⚖️ Fuel Type Comparison
Compare running costs for the same distance across fuel types.
Total Monthly km = (One-way × 2 × Working Days) + Extra km
Fuel Required = Total km / Mileage
Monthly Cost = Fuel Required × Price per Litre
Example: 25 km one-way, 22 days, 200 km extra, 15 km/L
Total km = 25 × 2 × 22 + 200 = 1,300 km
Fuel = 1,300 / 15 = 86.7 L
Cost = 86.7 × 103 = ₹8,929/month
Electric Vehicle Cost
kWh Required = Distance / Efficiency (km/kWh)
Cost = kWh × Electricity Rate
Example: 300 km, 6 km/kWh, ₹8/kWh
kWh = 300 / 6 = 50 kWh
Cost = 50 × 8 = ₹400
EV is typically 4-6× cheaper per km vs petrol
India: Petrol ~₹7/km vs EV ~₹1.3/km
Cost Per km
Cost per km = Fuel Price / Mileage
Petrol ₹103/L, 15 km/L: ₹6.87/km
Diesel ₹91/L, 18 km/L: ₹5.06/km
CNG ₹90/kg, 22 km/kg: ₹4.09/km
EV ₹8/kWh, 6 km/kWh: ₹1.33/km
Savings vs Petrol (monthly 1500 km):
Diesel: ₹2,715 saved
CNG: ₹4,170 saved
EV: ₹8,310 saved
