Risk build-up method is the most used for calculating the capitalization rates. With the help of the literature analysis, the origin of this method is considered. The method was based on the relationship between risk and profitability of a stock in exchange trading, proven statistically. Later, when formulating the build-up method, this idea was transferred without any justification to the valuation of enterprises that do not list their securities on stock exchange. In other words, the formulas traditionally used in the application of the build-up method are empirical in nature and not precise.It is more accurate to write them down by analogy with Irwin Fisher's equation of returns. Based on the principle of dependence, one of the main ones for the valuation procedure, the essence of which is that the value of the valuation subject depends on its economic location, a set of four independent risks is given for use in the build-up method in general case: risk-free rate, country risk premium, branch risk premium, and subject risk adjustment. It is noted that the numerical value of these parameters used in the method fundamentally depends on the monetary unit used in the calculation (the valuation currency). Recommendations are given on finding a risk-free rate for various currencies, on calculating country risk premium, branch risk premium, and subject risk adjustment.
