What decides the diesel price in Bihar
Diesel prices in India are revised every day at 6:00 AM. A few main things decide the rate you pay at the pump:
- Crude oil price: India imports most of its oil, so the global crude oil rate is the biggest driver of the diesel price.
- Rupee to dollar rate: Oil is bought in US dollars. When the rupee weakens against the dollar, fuel gets costlier.
- Central excise duty: A fixed tax set by the central government and added to every litre.
- State VAT: Each state adds its own tax, which is why the diesel rate is different from one state to another.
- Dealer commission: The amount the fuel station earns on each litre it sells.
- Freight and supply cost: Moving fuel from refineries and depots to local pumps adds to the final rate.
- Demand and supply: Higher demand or tight supply, such as during festivals or travel seasons, can push rates up.
How the diesel price is made up
The rate on the board is built from four main parts:
- Base price: The cost of the fuel itself, linked to international crude oil rates.
- Central excise duty: A fixed central government tax per litre.
- State VAT: A state government tax, charged as a percentage.
- Dealer commission: The fuel station’s margin on each litre.
