European integration is supported through important financial resources in order to sustain the investment effort for aligning the business infrastructure and increase in the business competitiveness in order to fulfill the European Union standards.

The financial management, a basic component of the general management, has as scope to realize complex financial analysis in order to substantiate the decisions for investments and financing which should ensure the maximization of results, ensuring also the elaboration of the project budget as an essential document in the identification of the needs for resources and for obtaining the non-reimbursable financial sources.

An essential role in the investment decision making, having as support European funding, is realized by the financial-accounting reporting documents such as balance sheet, profit and loss account, table of the treasury flows, which together with a realistic established actualization rate ensures the relevance and efficiency of the financial indicators: Net present Value(NPV), Internal Rate of Return(IRR), the investment recovery period, the benefit/cost ratio.

This study has as its goal to realize a critical analysis over the main simulation methods and techniques for forecasting annual return based on its growth rate, which should ensure the success of the implementation and operation of an investment realized through European structural funds respecting also the requirements for minimization of risks. In this research it is shown the importance of proper generation/modeling of the annual turnover in an investment project. Several methods were presented and case study was realized. Since the annual turnover constitutes the basis for the entire financial analysis it is very important that a realistic growth rate is used. Otherwise the provisions within the financial analysis of the investment (including CBA), the project implementation strategy and later the plan for the utilization of the newly realized investment might prove difficult to be fulfilled.
