Purchasing power of the consumer households one calls in private households for consumer purposes available incomes, thus that amount, which remains per household of the income, after all regularly returning liabilities (e.g. housing rents, credit rates, insurance premiums) were served. Usually the purchasing power is represented as size referred to the monthly income.

The purchasing power of a household is coupled not alone to the acquisition situation of the household members, but is subject to also clear regional differences. These differences are of great importance for the consumer goods industry, which must adapt their offers to the purchasing power available in a certain region, in order not to produce at the needs of the market past. The market study created itself in form of the so-called Nielsengebiete an instrument, in order to divide the surface of the Federal Republic of Germany into areas with relatively homogeneous purchasing power, which for a uniform marketing and marketing strategy are suitable.

The so-called purchasing power theory of the wages for purchasing power stimulation is disputed.

The available income of the private households represents a particularly expressive indicator for (monetary) the "“prosperity"” to the population and is as the amount to be understood, which stands for humans living in a certain region for consumer purposes or for saving formation for order. The available income results from the received primary incomes after departure of the performed current transfers and after adding the received current transfers. However the available income should not be equated overall with the term "“purchasing power"”, since purchasing power apart from the nominal money would have to consider also in principle the price level (real wages), while the available income considers no differences in prices as pure nominal money in principle.

For the retail trade also the plays an important role apart from the purchasing power. The is calculated by the relationship of the purchasing power index (purchasing power in the comparison to the Federal average) to the turnover index (retail turnover in the comparison to the Federal average).

Purchasing power index

The purchasing power index of a region indicates the purchasing power level of this region per inhabitant in the comparison to the national average. The national average has thereby the standard value 100. The purchasing power index of a region in Germany e.g. amounts to. , then he is appropriate for 84 easily below the Federal average - the inhabitants in this region have then on the average only 84 per cent of the average purchasing power of the German Federal Republic.

The computation purchasing power index is essentially based on wage and income statistics, i.e. on data of the tax offices and on data in connection with national transfer services (unemployed person and child benefit payments, pensions etc.).
