The main goals of each country are satisfied citizens, looking ahead to the prosperity of present and future generations. That is why it is a very important sustainable surplus of the current account balance account that will contribute to the reduction of foreign trade imbalances and the economic growth of the country. The study found that the global financial crisis has led to an end to the investment cycle, ie to the fall in gross fixed capital formation. Such movement indicates the movement of the balance of the current balance of payments account. Similarly, it was established that average gross investments in the observed period in the selected countries had the greatest impact on the decline in the value of GDP. Similarly, research has shown that investments and savings are highly related. The conducted research has shown that the regression and correlation model of savings serves for analytical purposes at the microeconomic and macroeconomic level. Research has shown that savings are associated with selected economic determinants. The conducted research has shown that the regression model is representative between saving and spending households, taxes and wages and salaries. The regression model is not representative between savings and the number of employees. The research carried out is in accordance with theoretical settings.
