Aggregate Capital Tied-up by Investment Projects——The Possibility of a Simple Estimation

The aggregate capital needs are a new business economics category which provides a new aspect to evaluate investment projects.The literature does not deal with this category as the project‘s total financial resource requirement.It is the total capital tied-up for the project in its lifetime.For calculation of it,the yearly capital tie-ups are being added together.Based on this,it can be examined the total capital amount,which results in a given net present value,or the total capital amount,which operates according to the given rate of profitability.The paper interprets the category,presents its relationship with the interest rate,and also presents the method of calculation based on model editing.In the case of the internal rate of return,the estimation may be greatly simplified.Instead of determining the yearly amounts and summation of these,the estimation can be carried out also with a simple division of two data.The paper demonstrates the possibility of simplification and shows an example to present the interrelations of data.
