Calculate trip fuel cost in seconds
Trip fuel cost depends on three factors: distance, vehicle mileage (fuel efficiency), and fuel price. This calculator gives you instant cost estimates for any trip.
Fuel Needed = Distance (km) / Mileage (km/l)Total Cost = Fuel Needed x Price per liter| Vehicle | City (km/l) | Highway (km/l) | Cost per km at ₹95/l |
|---|---|---|---|
| 110cc commuter motorcycle | 55–65 | 65–75 | ₹1.4–1.7 |
| 150cc motorcycle | 40–45 | 45–50 | ₹2.0–2.4 |
| 125cc scooter | 38–45 | 42–48 | ₹2.1–2.5 |
| Small hatchback, petrol | 15–18 | 20–22 | ₹4.3–6.3 |
| Compact sedan, petrol | 13–16 | 18–21 | ₹4.5–7.3 |
| Compact SUV, petrol | 11–14 | 16–18 | ₹5.3–8.6 |
| Compact SUV, diesel | 15–18 | 20–23 | ₹3.9–5.9 |
| Hybrid hatchback / sedan | 22–27 | 24–28 | ₹3.4–4.3 |
| CNG hatchback | 26–30 km/kg | 30–33 km/kg | ₹2.6–3.4 at ₹85/kg |
| 7-seat MPV, diesel | 13–16 | 17–20 | ₹4.4–6.5 |
281 km each way, 562 km round trip, petrol SUV at 14 km/l, ₹95.4/l
562 ÷ 14 = 40.1 litres
40.1 × 95.4 = ₹3,829 in fuel
Add NH-48 tolls of roughly ₹700 each way
About ₹5,200 for the round trip — ₹9.3 per km all-in, or ₹1,300 a head split four ways.
The figure printed in a brochure comes from a standardised lab cycle (India moved to the MIDC-based cycle and, for newer certifications, to a WLTP-derived procedure). Real-world numbers land 15–30 % lower. The honest way to know your own is the tank-to-tank method: fill to the automatic click, zero the trip meter, drive normally for at least 250 km, refill to the click at the same pump, then divide the trip distance by the litres it took. Repeat over three tanks and average — one tank is noise.
Divide the trip distance by your vehicle’s real-world mileage in km per litre to get litres, then multiply by the current price per litre. For a return trip, double the distance before you start.
Fill the tank to the automatic cut-off, reset the trip meter, drive at least 250 km in your normal pattern, then refill to the cut-off at the same pump. Trip kilometres divided by litres added is your true mileage. Average three tanks.
Per kilometre usually yes, because diesel engines return 20–30 % better mileage and the fuel is priced slightly lower in most states. But the diesel variant costs more to buy and more to service, so the break-even is typically somewhere around 15,000–20,000 km a year.
On running cost, clearly — a CNG hatchback often costs under ₹3 per km against ₹5–6 for the petrol version. The trade-offs are boot space taken by the cylinder, a small power drop, and refuelling queues outside the metros.
In slow city traffic, yes, by around 5–10 %. On a highway it reverses: open windows at 100 km/h add enough aerodynamic drag to cost more than the compressor does.
