Common Questions


  • What does IGP mean?

    IGP is the acronym in Portuguese for General Price Index, a result that aggregates three indexes: Broad Producer Price Index (IPA), Consumer Price Index (CPI) and National Construction Cost Index (INCC). The weights assigned to these indices are 6, 3 and 1, respectively. Aggregation is made from index numbers, a way the FGV traditionally uses for the dissemination of results.


  • What is IGP for?

    Briefly, the IGP, besides an economic indicator widely reported, serves as a reference for pricing and financial values. Contracts of residential and commercial rents, utility charges, state debts to the Union, budget of the Federal Government, financial investment funds, among others, use the IGP for updating their values. 

  • Why are released multiple versions of IGP (IGP-DI, IGP-M and IGP-10)?

    Each index has its own timetable for price collection and dissemination of results, according to its frequency. Between the collection of prices and the release of final figures it requires a period in which the results are determined. 

    The indexes calculated for the calendar month, that is, with price collection between the 1st and the 30th are disclosed within 7 days of the closing of the collection. In the case of the IGP-M, whose collection is from the 21st of the previous month to the 20th of the reference month, the dissemination of results always takes place on the penultimate working day of the reference month. The following table shows the differences in collection periods for each version of IGP:


  • How are the FGV price indexes disclosed?

    FGV releases its price indexes based on: fixed base index numbers (to 3 decimal places) monthly rates of change and cumulative rates in the year and in 12 months (with 2 decimal places). The indexes are published in  Press Release and  Database (FGVDADOS) on Access via IBRE Portal:

  • How can I get the release timetable of FGV indexes?

    The calendar is available on the IBRE’s website:

  • Access to FGV data is made only through the Internet? Can I go there and get the data for free?

    FGV's technicians have no customer service. Free series and other calculation tools are available only on the IBRE Portal. Contact Us via IBRE Portal:

  • What is the Official Inflation Monitor?

    It is a system intended to support the analysis and forecasting of price indexes. The system consists of two modules. The first one is aimed to the simulation of IPCA and IPCA-15, combining the IBGE weighting structure to the price collection by FGV/IBRE. The second one shows daily the rates of change for all sub-items in IPC/FGV.

  • What are the most common uses of IPCs?

    Several price indexes are produced to measure different aspects of inflation.  IPCs measure the inflation experienced by consumers in their day-to-day expenses. They are usually used for wage adjustment.

    Consumer prices differ from Producer ones (IPA) because of tax incidence, as well as transportation and marketing margins.

  • What is the Consumer Price Index for the Elderly - IPC-3i?

    This version of IPC was developed based on families composed chiefly of individuals over 60 years of age. With this version of IPC it is possible to observe how the change in prices of goods and services affects the cost of living for this portion of the Brazilian population. In addition to measuring changes in the cost of living for individuals over 60 years of age, the IPC-3i is a reference to the implementation of public policies in the areas of health and welfare.

  • What is the Consumer Price Index class 1 - IPC-C1?

    It measures the change in prices of a basket of goods and services whose families earning between 1 and 2.5 minimum wages have increased consumption or commitment of income. Usually based on POF data, families with lower incomes spend larger portions of their expenses with food, while other families spend most of their income on education or health.
