Financial literacy as a key element of ensuring sustainability and stability of economic systems is becoming important in the process of economic development. Financial literacy contributes to improving the well-being of citizens and the efficiency of financial resource management at the macro level. Thus, the purpose of the present study was to develop models for evaluating the effectiveness of various financial literacy strategies and their impact on the formation of life projects. A complex of scientific methods, including the analysis of statistical data and modelling of financial behaviour, was used to create a strategic model of financial literacy as a concept of a life project. A methodological approach, encompassing the decomposition of the stages of a person’s life and the identification of the peculiarities, connected with the use of money at each of these stages, was implemented in the research. Approaches to financial literacy focused on various forms of interaction with financial resources were suggested, and effective strategies for improving financial literacy were identified. The concept of financial literacy was examined and specified through the lens of knowledge, skills, and confidence for making responsible financial decisions. The advantages and disadvantages of developing financial literacy in Ukraine were identified, and examples of successful strategies of leading countries were provided. The importance of financial education at different stages of a person’s life was substantiated; the key periods of a person’s life and development, when money can act as earnings, expenses, accumulation, preservation, and transfer, were specified. The assessment of the influence of financial literacy on economic behaviour was carried out, and a life project model that takes into account financial decisions and actions was developed. Monetary models of preservation and accumulation of parental income, pocket money, and earnings from employment were considered in detail. The results of this study can be applied in practice when creating a state strategy aimed at increasing the level of financial literacy of the population and ensuring economic security
