Diesel prices in Patna depend on state VAT, dealer commission, and freight costs from the nearest supply depot, which is why rates can vary compared to other cities in the region. Local factors such as distance from the nearest refinery or bottling plant also play a role in the final price consumers pay at the pump in Patna.
Like other fuels, diesel rates in Patna are reviewed daily based on changes in international crude oil prices and the rupee-dollar exchange rate. This dynamic pricing approach means that even without any change in local taxes, the price in Patna can shift slightly from one day to the next.
Figures displayed here are sourced from primary oil marketing companies and updated daily, offering residents, transporters, and fleet operators in Patna a trustworthy, real-time snapshot of diesel prices for better budgeting and planning.
Patna's state levies its own VAT on diesel, 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.

The base refinery price and dealer commission are broadly common, but the state's VAT rate and local freight are what set Patna's final pump price.
Use the monthly diesel cost calculator on this page. Enter your daily commute distance, working days per month, and vehicle mileage in km/L. The calculator uses today's diesel rate of ₹99.36/L in Patna to show your monthly fuel spend and yearly total. Toggle between one-way and round-trip modes depending on whether you drive back the same day.
Note your odometer reading when you fill the tank, then note it again at the next refuel. Enter both readings and the litres filled between them into the mileage checker on this page — you'll get your real km/L along with a good, average, or poor efficiency rating. Switch between passenger car and commercial truck for the right benchmarks, since good mileage for a truck is very different from a car.
Use the fleet fuel cost calculator on this page. Enter the number of trips per month, average distance per trip, and your truck's mileage. It shows your monthly diesel bill, cost per trip, and cost per kilometre — the last two are what you need for freight pricing and margin decisions. At today's ₹99.36/L diesel rate in Patna, a truck doing 20 trips of 300 km at 5 km/L mileage spends roughly ₹1.19 lakh a month.
It depends on how much you drive. Diesel cars cost more upfront but give better mileage and use cheaper fuel. Use the Diesel vs Petrol total cost of ownership calculator at the bottom of this page — enter both car prices, both mileages, your annual kilometres, and ownership years to see the breakeven distance and 5-year total spend on each. As a rough guide, diesel typically wins if you drive over 15,000 km a year for 5+ years.
Diesel hatchbacks and sedans typically deliver 18–24 km/L, and diesel SUVs 12–18 km/L. Commercial trucks range from 4–7 km/L depending on load and terrain. If your vehicle is delivering meaningfully less, a service, cleaner fuel, or better driving habits often help. Use the mileage checker on this page to measure your real km/L.
