Real wage is a wage deflated by the current consumer price index. It gives information on how much current wage compares to the wage of given base year period. Real wage is obtained by dividing the nominal wage by the current Consumer Price Index (CPI) of a given month multiplied by 100. Table 1 below presents the real wage and nominal wage of non-agriculture workers in the Philippines as of December 2019 by region.
