More about the survey
To calculate the IPCA-15, the methodology is the same as the one used for the IPCA; the difference lies in the period of price collection and in the geographic coverage. In order to estimate the IPCA-15, prices were collected from March 18 to April 14, 2025 (reference) and compared with those in effect from February 13 to March 17, 2025 (base).
