Today’s petrol price in Patna is ₹113.37 per litre and diesel is ₹99.36 per litre (as of 9 June 2026). Prices update every day at 6:00 AM. That makes Patna, a Tier 2 city in Bihar, about ₹11.25/litre costlier than Delhi (₹102.12).
Bihar layers an additional irrecoverable tax over VAT, so Patna petrol stays above the ₹105 mark.
What makes up the petrol price in Patna
Every litre of petrol in Patna carries two central charges that are the same across India, plus Bihar’s own state tax on top. Bihar levies approximately 23.58% + irrecoverable tax on petrol, and that state slab is the single biggest reason Patna prices differ from a city like Delhi.
| Component | Amount (₹/litre) |
|---|---|
| Base price (ex-refinery) | ~56.00 |
| Central excise duty | 19.90 |
| Bihar state tax (VAT/cess) | ~33.60 |
| Dealer commission | ~3.87 |
| Total pump price | ~113.37 |
The base price and excise duty are fixed nationally. State tax is the variable layer, so two cities can sell the same fuel at very different pump prices purely because of state politics.
Petrol price history in Patna (recent months)
| Month | Petrol (₹/L) | Diesel (₹/L) |
|---|---|---|
| June 2026 | 113.37 | 99.36 |
| May 2026 | 113.37 | 99.36 |
| April 2026 | 113.37 | 99.36 |
| March 2026 | 113.37 | 99.36 |
| February 2026 | 113.37 | 99.36 |
Pump prices across India have been broadly stable since the May 2022 excise cut, when fuel was reduced by about ₹8/litre nationally. Daily revisions by the oil marketing companies have stayed small since then, so the Patna figure moves only in paise on most days.
