Since then the indicies record the changes in prices of raw agricultural and industrial products and intermediate and final goods and services.
There are three different inflation indicies:
- General Price Index (Índice Geral de Preços – 10 (IGP-10)
- General Market Price Index (Índice Geral de Preços do Mercado (IGP-M)
- General Price Index Domestic Supply (Índice Geral de Preços – Disponibilidade Interna (IGP-DI))

The IPG-10 Index measures the prices in the period of the 11th of the past month to the 10th of the present month. The index has first been collected in 1993.
The IPG-M index measures prices in the period of the 21th of the previous month to the 20th of the present month. The index has been introduced in 1989.
The IPG-DI index compares prices from the first to the last day of the present month and was first measured in 1944.
The IPG-M, different from the other two indicies, is based on a system of previously released tabulations before the month’s end. The tabulations represent partial results of the index based on information collected in 10 days.
The first preview of the index, measured from the first 10 days, calculates the price variations in the period of the 21st to the 30th of the past month to the present month. The second preview of the index expands this time frame to the period from the 21st of the past month to the 10th of the present month.
The third and last preview of the index is the correct IPG-M.
