This study is devoted to considering the level of influence of some factors on the growth of teachers' incomes in the digital economy. The main research hypothesis is that there is a certain level of influence of qualitative and quantitative factors on the relationship between sales of digital educational products (resources) and the income of authors. The analysis in the article was carried out using the fuzzy output logic method in the MATLAB software package. Statistical data from Azerbaijan for the years 2010–2020 were used in the study. It was determined that quality indicators such as the ease of finding the digital product during the search, the availability of new information on the digital educational product, the image of the product owner, and the usefulness of the digital educational product for the buyer have a moderate to high effect on the increase of the authors' income.
