How does the Palkkadata.fi website work?
Methodology of salary survey Palkkadata.fi
Palkkadata.fi is a website where you can get a comparison of the salaries of about 500 positions. The list of positions reflects the labour market in Finland and is constantly updated. This salary survey was launched in 2014 as Palkkadata.fi. Alma Career Oy is the author of the methodology concerning the acquisition, collection and processing of the data gathered in the survey, and its subsequent evaluation.
The target group of the portal is people in the
labour market who want to compare their salary.
1. Input data
People in the labour market can get a comparison of their salary with other employees in the same position and region. Everyone who completes the questionnaire with 14 questions (8 of which are compulsory) becomes a respondent, and receives a free salary comparison with the average of the reference sample. This is created by other respondents according to the position and region filled in the questionnaire.
The data from each respondent are valid for one year, and there is no interference with the information entered in any way. All data in the salary survey are anonymous.
2. Output data
Prior to actual calculations, the sample data is cleaned up. Errors such as negative numbers, extreme values (e.g. EUR 1 / month or EUR 10 mil. / month are filtered out first. The second step in cleaning the database is to detect duplicate questionnaires and to determine extremes. Extremes are determined specifically for a particular position with regard to the region (Helsinki region, outside the Helsinki region). The methodology for detecting extreme data (data trimming) is based on the robust estimations of parameters regarding the theoretical distribution of salaries in a particular position by region.
Data from the questionnaires that have undergone cleaning are used in the calculations.
Survey results publish only information from the data that has been accepted:
- one profile (output of the questionnaire) is used as a sample for one year,
- we never interfere with completed questionnaires,
- inflation or cost of living are not taken into account during the calculations,
- we never estimate salaries in one region according to another region.
For a more vivid understanding of the results of salary comparisons, we also provide their graphic representation.
3. Outputs for people

comparison of actual or anticipated salary are shown. Outputs are displayed
