Gross disposable income and purchasing power

The gross disposable income (GDI) is the income available for the households, after the payment of current taxes on income and wealth, social contributions and the reception of social benefits other than social transfers in kind and other current transfers.

The evolution of the purchasing power of the GDI weights the evolution of the GDI with the final consumption expenditure price index. To obtain a more accurate measure of the purchasing power, its evolution is assessed per person, household and consumption unit.

Following the recommendations of the commission concerning the "Measurement of the purchasing power of the households" an arbitrable disposable income, closer to the perception of the households, is also calculated.
