Abstract
The article considers the theoretical and practical problems of the project efficiency calculating on the example of one of its main estimated indicators ‒ NPV (net present value). The discounted project performance indicators used by most theorists and analysts in some cases do not reflect the real project profitability (unprofitability). The net present value calculation for various options for the nature of projects cash flow is shown in a number of simulated examples. It is shown that for some unprofitable projects the net present value indicator, nevertheless, indicates a positive effect, which contradicts with idea of this indicator using for evaluating of alternative projects efficiency. This situation is typical for projects with long-term loans and quick returns on capital investments. We believe that this situation arises as a result of the fact that costs include in the calculations of performance indicators, which are discounted simultaneously with revenues and thus numerically increase the discounted level of project profitability (when discounting a negative amount of costs, total profitability increases). Although, if we proceed from the theory of money value over time, exactly costs create a future value ‒ PV. The article analyzes the considered contradictions of performance indicators of various project options and proposes a new indicator for projects efficiency evaluating.
Highlights
‒ if NPV> 0, PI> 1, IRR> i; ‒ if NPV
Most of the authors [2‒6; 9; 10] and analysts use a set of efficiency criteria that describe the feasibility of the project from different angles. They use the index of net present value (NPV) as the main indicator of the project profitability which can be updated taking into account the time factor
NPV stands for the difference between the discounted for a moment incomes measures В (t) and expenditures for the realization of the project C (t)
Summary
It is generally accepted that there is such an estimation rule of an effective project [2‒6; 8‒11]:. ‒ if NPV> 0, PI> 1, IRR> i (the project is effective); ‒ if NPV
