| Distance | Petrol (15 km/L) | Est. cost @ ₹105/L |
|---|---|---|
| 100 km | 6.67 L | ₹700 |
| 300 km | 20.00 L | ₹2,100 |
| 500 km | 33.33 L | ₹3,500 |

Mileage & efficiency
Mileage calculator India (km per litre)A fuel cost calculator India workflow is: find litres for the trip, multiply by what you pay at the pump. Use illustrative price bands below as a starting point, then type your actual rate into the fuel cost calculator or the quick tool above.
Total fuel cost = (Distance ÷ Mileage) × Fuel price per litre
Example: 500 km journey with 15 km/L mileage at ₹105/L
Cost = (500 ÷ 15) × 105 = ₹3,500
Rates change by city and date—confirm at your pump before claiming expenses.
Petrol
₹95–110/L
Varies by state and taxes
Diesel
₹85–100/L
Often below petrol per litre
CNG
₹75–85/kg
Use km/kg in the same distance logic
| Daily distance | Mileage | Fuel price | Monthly cost |
|---|---|---|---|
| 20 km | 15 km/L | ₹105/L | ₹4,200/month |
| 40 km | 18 km/L | ₹95/L | ₹6,333/month |
| 60 km | 22 km/L | ₹90/L | ₹7,364/month |
Use our fuel cost calculator for your own distance, price, and km/L.
When you already logged a full tank, the fuel efficiency calculator helps turn odometer and litres into km/L and cost per km. When you want clean unit conversion or a quick mileage calculator for car checks, use the mileage calculator (km per litre and related formats).
For “how many litres for this trip?”, pair those mileage numbers with the fuel consumption calculator.
Enter distance in km, your mileage (km/L or km/kg for CNG), and local price per unit. Litres needed = distance ÷ mileage; trip cost = litres × price. For routes and tolls together, use the trip fuel calculator after you have mileage and price.
Divide 500 by your km/L. Example: at 15 km/L you need 500 ÷ 15 ≈ 33.3 L. Use your car or bike figure, then multiply by ₹/litre for petrol cost for that trip. Open the petrol required for 500 km page for a query-focused walkthrough.
Mileage usually means km per litre (how far you go on one litre). Fuel consumption often means litres used for a given distance—the same numbers, different view. Use the fuel consumption calculator for how many litres for X km; use a mileage calculator for car readings when you care about km/L or cost per km.
Use cost per km = fuel price ÷ km/L, or open the fuel cost calculator for distance and monthly-style estimates in one place.
Yes. Keep the same distance ÷ mileage step; plug in diesel ₹/L or CNG ₹/kg and km/kg where applicable. Child tools go deeper on each case; this page is the map.
Same site, different jobs: trip planning with the trip fuel calculator, litres-by-distance with the fuel consumption calculator, km/L focus with the mileage calculator, and budgets with the fuel cost calculator. For receipts and claims, use the fuel bill generator.
