How prices are formed


Production with the fuel you use today started 10 years ago.

Get to know the journey of Oil to understand the price of diesel.

Producing the fuel you use today starts with the discovery of reservoirs and the construction and installation of platforms up to 300 km from the coast, to extract the oil that is up to 7 thousand meters deep. From there, the oil goes to refineries, where it is transformed into derivatives, including diesel of low sulfur content (S10). 

The data are public and you can consult them whenever you want, here or on the ANP website.


After the refinery, the diesel is sold to distributors, and taxes are included.

After being produced, the fuels are sold to distributors, at which point the fuel taxes are added. Federal taxes are CIDE, PIS/PASEP and COFINS.¹ 
In addition to them, the state tax is also added, in this case, the ICMS, which is incorporated into the amount charged at the refineries following the tax substitution rule and considering the Weighted Average Price to the Final Consumer (PMPF) defined by the States. 

Value of federal taxes:

R$ 0.0¹

Value of ICMS:

R$ 0.91

1. As determined by Complementary Law No. 192/2022, federal taxes for diesel and biodiesel are zeroed until 12/31/2022. 


Distributors then need to add biodiesel to diesel.

Fuel distributors buy type “A” diesel from refineries. According to Brazilian legislation, automotive diesel must be mixed with biodiesel, a renewable fuel produced from vegetable oils or animal fats, forming diesel oil “B”, which is sold at gas stations.

The price of biodiesel² is freely negotiated between distributors and production plants. For 2022, the mandatory blending content of biodiesel is 10%.³  

Value of the biodiesel portion:

R$ 0.61

2. Biodiesel reference value R$0.00 per liter. Source: ANP. 

3. Composition considered: 90% diesel and 10% biodiesel.

Distribution and resale

Finally, distributors and dealers sell gasoline at gas stations.

At this stage, distributors and dealers add their own costs and profit margin to the previously paid prices.⁴ Under the 1997 Petroleum Law, pricing at all stages of the chain is free. 

Distribution and resale value:

R$ 0.85

4. The share of distribution and resale margins is estimated.

As you can see, Petrobras⁵ is responsible for a part of the price of your fuel, but other factors enter into the calculation of the price⁶ that reaches you.
