Calculate Fuel Cost for Any Trip in India

Planning a road trip or daily commute? Our fuel cost calculator helps you estimate the exact cost of fuel for any journey in India. Enter the distance, your vehicle's mileage, and the current fuel price to get an instant estimate. You can also split the cost between passengers - perfect for carpooling and group road trips.

Fuel prices in India vary by city and are revised daily by oil companies based on international crude prices and rupee-dollar exchange rates. Petrol prices in major cities typically range from Rs.90-110 per litre, while diesel ranges from Rs.80-95 per litre.

Typical Mileage for Popular Indian Vehicles

  • Maruti Swift: 22-25 km/l (petrol)
  • Hyundai Creta: 16-18 km/l (petrol)
  • Honda Activa: 45-50 km/l (petrol)
  • Royal Enfield Bullet: 35-40 km/l (petrol)
  • Mahindra Scorpio: 13-15 km/l (diesel)
  • Tata Tiago CNG: 26-28 km/kg (CNG)

How to estimate fuel cost for a trip

Enter your trip distance, your vehicle mileage and the current petrol, diesel or CNG price. The calculator works out how much fuel the trip needs, the total rupee cost and the cost per kilometre. Useful for one-off trips, daily commutes or budgeting a month of driving.

How many litres for a fixed budget

If you already know your budget and want to work backwards, divide the amount by the current per-litre price to see how many litres it buys. For example, at ₹95 per litre, ₹5,000 gets you just over 52 litres of diesel. You can also reverse it: enter the litres you expect to need and estimate the final cost before you drive to the pump.

Fuel cost for distance-based planning

For longer trips, start with distance divided by mileage to get the litres required, then multiply by the current fuel price. A 1,000 km highway run in a car that does 18 km/l needs about 56 litres. At ₹100/litre, that works out to ₹5,600 in fuel alone. Handy for planning road trips, taxi routes and monthly commute budgets.

Useful before a trip

  • Compare petrol vs diesel running cost for the same route
  • Estimate how much each passenger should pay in a group trip
  • Check whether a longer route with better mileage may cost less overall
  • Budget recurring office or school commute expenses more accurately

How to Use the Fuel Calculator - Step by Step

Estimating trip fuel cost takes under a minute if you have the three key inputs ready:

  1. Enter the trip distance in kilometres. For known routes, confirm the distance on Google Maps. For a daily commute, multiply the one-way distance by two and by the number of working days if you want a monthly figure.
  2. Enter your vehicle mileage. Use km/l for petrol and diesel vehicles, or km/kg for CNG. Your owner's manual lists ARAI-certified mileage, but real-world figures are typically 10-20% lower. Use your last few tank fill-ups to calculate actual mileage: litres filled divided by kilometres driven since the previous full tank.
  3. Enter the current fuel price per litre or per kg. Fuel prices in India are revised daily at 6 AM. Check live prices on the IOCL, BPCL or HPCL websites, or on the official apps such as IndianOil ONE, BPCL SmartDrive or HP Pay before filling up.
  4. Optionally split the cost. Enter the number of passengers to divide the total equally. This is useful for carpools, office cabs, and group road trips where each person pays a fair share.

Fuel Cost Formula with Indian Route Examples

The three formulas the calculator uses are simple enough to do by hand:

  • Fuel required (litres) = Distance (km) ÷ Mileage (km/l)
  • Total cost (₹) = Fuel required × Price per litre
  • Cost per km (₹) = Price per litre ÷ Mileage (km/l)

Worked examples on popular Indian routes. Prices used below are illustrative only - plug your actual mileage and today's pump rate into the calculator for a real estimate:

  • Mumbai to Pune (150 km via Mumbai-Pune Expressway) in a Maruti Swift at 22 km/l, petrol at ₹105/l - 6.82 litres needed, total ₹716, cost per km ₹4.77.
  • Delhi to Agra (210 km via Yamuna Expressway) in a Hyundai Creta at 17 km/l, petrol at ₹95/l - 12.35 litres, total ₹1,173, cost per km ₹5.59.
  • Bengaluru to Chennai (345 km via NH48) in a Mahindra Scorpio diesel at 14 km/l, diesel at ₹90/l - 24.64 litres, total ₹2,218, cost per km ₹6.43.
  • Delhi to Jaipur (265 km via NH48) in a Tata Tiago CNG at 26 km/kg, CNG at ₹77/kg - 10.19 kg, total ₹785, cost per km ₹2.96.

Round-trip costs are roughly double the one-way figure. Add 10-15% for city traffic, stop-go driving and AC use on summer trips.

Rupees to Litres - Quick Reference

How many litres you get for a fixed rupee amount depends on the current pump price in your city. The table below uses representative 2026 prices; switch the calculator above to the "Rupees to Litres" mode and enter your local price for the exact answer.

AmountPetrol @ 105/LDiesel @ 92/LCNG @ 80/kg
1000.95 L1.09 L1.25 kg
5004.76 L5.43 L6.25 kg
1,0009.52 L10.87 L12.50 kg
2,00019.05 L21.74 L25.00 kg
5,00047.62 L54.35 L62.50 kg

Formula: Litres = Budget ÷ Price per litre. At 100/L exactly, 500 buys 5 L and 1,000 buys 10 L. CNG is sold per kilogram, so the unit changes but the math is identical.

Cost of X Litres of Fuel - Quick Reference

Going the other way, here is what common volumes cost at representative 2026 pump prices. Use the "Litres to Cost" mode above with your city's current price for a precise figure:

VolumePetrol @ 105/LDiesel @ 92/L
5 L525460
10 L1,050920
15 L1,5751,380
30 L3,1502,760
45 L4,7254,140
50 L5,2504,600
65 L6,8255,980
80 L8,4007,360

Formula: Total cost = Volume × Price per litre. Car fuel tanks are typically 35-60 litres (hatchbacks/sedans) or 55-80 litres (SUVs); bikes hold 10-18 litres. Pick the volume closest to your tank size for a full-tank estimate.

Fuel Prices Across Major Indian Cities

Petrol and diesel prices vary by city because state VAT, freight costs and local cess differ. Oil marketing companies (IOCL, BPCL, HPCL) revise rates daily at 6 AM based on international crude prices and the rupee-dollar exchange rate. The table below shows broad price bands that have held across recent months - treat them as a rough sanity check, not a quote. Always verify the current pump price on the official OMC website or app before budgeting a trip:

CityPetrol (₹/l)Diesel (₹/l)CNG (₹/kg)
Delhi94-9687-8976-78
Mumbai103-10690-9275-77
Bengaluru102-10488-9085-88
Chennai100-10392-9486-88
Kolkata104-10691-93Limited
Hyderabad107-11095-9785-87

Prices shown are indicative ranges based on recent trends and will drift with daily OMC revisions, state tax changes and crude price movements. The calculator accepts any price you enter, so it works across cities and fuel types - use the live rate from your nearest pump for an accurate answer.

Petrol vs Diesel vs CNG - Running Cost Comparison

For the same vehicle body style (typically a compact SUV or sedan), the three fuel types produce very different running costs. The figures below use representative real-world mileage and round-number fuel prices to illustrate the gap - your actual cost per km depends on your vehicle and your local pump rate:

FuelTypical MileageTypical PriceCost per km
Petrol18 km/l₹100/l₹5.56
Diesel22 km/l₹90/l₹4.09
CNG25 km/kg₹77/kg₹3.08

CNG offers the lowest running cost but its refuelling network is still concentrated in major metros and nearby highways. Diesel is cheaper per km than petrol, but diesel vehicles cost more upfront and have higher service costs - the break-even point for buying diesel over petrol is usually 15,000-20,000 km per year for at least five years. Note that NGT rules prohibit diesel vehicles older than 10 years from plying in Delhi-NCR, and several other cities are expected to follow, so resale value and usability matter when choosing between fuels.

A bike at 45 km/l on the same Rs 500 covers about 214 km. Use 'Rupees to Litres' mode with your mileage for the exact distance.
How do I calculate fuel cost per kilometre?+
Divide the fuel price per litre by your vehicle's mileage in km/l. For example, if petrol is Rs 100/litre and your car does 20 km/l, your fuel cost per km is Rs 5.
What is car mileage and how do I calculate it for my Indian car?+
Mileage is the distance your vehicle travels per unit of fuel, measured in km/l (km/kg for CNG). To measure real-world mileage: fill the tank full, reset the trip meter, drive normally, and on the next full fill-up divide the trip kilometres by the litres filled. Real-world mileage is typically 10-20 percent lower than the ARAI-certified figure in the owner's manual.
Is diesel cheaper than petrol for running cost in India?+
Usually yes. With petrol at about Rs 100/l and mileage around 18 km/l, running cost is roughly Rs 5.56/km. With diesel at about Rs 90/l and mileage around 22 km/l, running cost is roughly Rs 4.09/km. However, diesel cars cost more upfront and have higher maintenance, so the total cost advantage only shows up if you drive 15,000-20,000 km or more per year.
Which is cheapest to run - petrol, diesel, or CNG?+
CNG is typically the cheapest at roughly Rs 3.00-3.10 per kilometre, followed by diesel at about Rs 4.00-4.20 and petrol at about Rs 5.50-5.60 for a comparable car. CNG's drawback is limited pump availability outside metro cities. Use the calculator to compare with your specific vehicle and local fuel prices.
