Living wage is defined as the income needed for a decent living, i. e. the wage needed to cover only the necessary living costs of an individual or family. Living wage for an individual is calculated by WageIndicator according to its own methodology based on the living cost prices collected in the WageIndicator Cost of Living survey. As the prices collected for various items differ by respondent, the living wage has to be calculated based on price figures reliable enough that a reasonable percentage of respondents reported that the goods are affordable for that price. Therefore, the living wage is provided as an interval of two figures (lower bound and upper bound living wage) instead of a single figure. The lowest (lower bound) living wage is always calculated from the 25th percentiles of prices collected for each item entering the living wage calculation.
