Beyond today's rate, these calculators help you plan around it — budgeting your commute, checking your car's real efficiency, and splitting a road trip bill. Every result updates live using the current petrol rate in Samastipur.
Petrol rates in Samastipur are shaped by state VAT, dealer commission, and transportation costs from the nearest fuel depot, which explains why prices can differ from neighbouring cities and states. Because VAT is applied as a percentage rather than a flat amount, even small movements in the base fuel price get amplified differently depending on the local tax rate in Samastipur.
Daily revisions in Samastipur also reflect changes in international crude oil benchmarks and the rupee-dollar exchange rate, which oil marketing companies review each morning before announcing new rates. This is why petrol prices in Samastipur can move slightly up or down even on days when there is no major news event.
The rates published here are sourced from primary oil marketing companies and refreshed daily, giving residents and commuters in Samastipur a dependable, up-to-date reference for current petrol prices without needing to check multiple websites or visit a fuel station.
Samastipur's state levies its own VAT on petrol, and some cities add a small local body tax or cess. That tax gap accounts for most of the price difference you see between cities.

Enter both readings and the litres filled in between into the mileage checker on this page — you'll get your real km/L, your cost per kilometre at today's rate, and a good, average, or poor efficiency rating. Real-world mileage is usually well below the manufacturer's claimed figure, so measure it before deciding anything.
Planning a weekend road trip to a nearby hill station or beach? Use the road trip cost calculator on this page. Enter the distance, your vehicle's mileage, and how many people are travelling — you'll get the total fuel cost, each person's share, and the there-and-back round-trip figure so nobody underpays on the return leg. At ₹113.58/L in Samastipur, a 350 km drive at 16 km/L needs about 21.9 litres, or ₹2,485 one-way — ₹621 each with 4 travellers.
For petrol cars, anything above 18 km/L is good, 12–18 km/L is average, and below 12 km/L is worth investigating. Hatchbacks typically deliver 16–20 km/L, sedans 14–18 km/L, and SUVs 10–14 km/L. Bikes and scooters are in a different league at 40–60 km/L. Under-inflated tyres, a clogged air filter, a skipped service, and hard acceleration are the usual causes of a sudden drop — use the mileage checker on this page to measure your real km/L before and after fixing them.
