The aim of this paper is to compare the impact of national culture on financial health considering Hofstede's cultural dimensions. For this purpose, the nonlinear cross-sectional soft transition threshold (CS-STR) model was used based on cross-sectional data for 50 developing countries and 58 developed countries in 2023. The results of estimating the nonlinear part of the model (second regime) for developed countries show that for a one-unit increase in power distance, uncertainty avoidance, individualism, masculinity, long-term orientation, and judicial effectiveness, financial health increases by 0.11, 0.07, 0.04, 0.0003, 0.05, and 0.08 units in developed countries, respectively. For developing countries, for every one unit increase in uncertainty avoidance, individualism, long-term orientation, and judicial effectiveness, financial health increased by 0.02, 0.03, 0.05, and 0.003 units, respectively. Also, the power gap and government debt lead to a decrease of 0.08 and 0.06 units in financial health in developing countries, respectively. In countries with a higher power gap, conflicts arise between the powerful and the powerless. In contrast, societies with a lower power gap are more harmonious, with an average power gap of 54% for developed countries and 74% for developing countries. Uncertainty avoidance through reduced uncertainty (uncertainty) and high individualism through greater participation in the market and more efficient contract enforcement lead to increased financial health. Long-term orientation towards thrift and seriousness in achieving individual goals and judicial effectiveness leads to improved financial health
