Today’s petrol price in Guwahati is ₹105.73 per litre and diesel is ₹97.23 per litre (as of 9 June 2026). Prices update every day at 6:00 AM. That makes Guwahati, a Tier 2 city in Assam, about ₹3.61/litre costlier than Delhi (₹102.12).
Assam applies a higher-of VAT formula, though periodic rebates keep Guwahati near the national average.

What makes up the petrol price in Guwahati
Every litre of petrol in Guwahati carries two central charges that are the same across India, plus Assam’s own state tax on top. Assam levies approximately 32.66% or ₹22.63/L (higher) on petrol, and that state slab is the single biggest reason Guwahati prices differ from a city like Delhi.
| Component | Amount (₹/litre) |
|---|---|
| Base price (ex-refinery) | ~56.00 |
| Central excise duty | 19.90 |
| Assam state tax (VAT/cess) | ~25.96 |
| Dealer commission | ~3.87 |
| Total pump price | ~105.73 |
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 Guwahati (recent months)
| Month | Petrol (₹/L) | Diesel (₹/L) |
|---|---|---|
| June 2026 | 105.73 | 97.23 |
| May 2026 | 105.73 | 97.23 |
| April 2026 | 105.73 | 97.23 |
| March 2026 | 105.73 | 97.23 |
| February 2026 | 105.73 | 97.23 |
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 Guwahati figure moves only in paise on most days.
Monthly fuel cost for Guwahati commuters
At ₹105.73/litre, here is what 1,000 km a month costs on common vehicles. The formula is simple: monthly fuel cost = (monthly km ÷ mileage) × petrol price.
