Investment feasibility indicators: NPV, IRR, DPB
Net Present Value (NPV) is a tool for measuring the difference between the current value of cash flows from an investment and the costs associated with it. This tool allows us to assess the profitability of a project and is used for comparing various opportunities within a company and making financing decisions.
Internal Rate of Return (IRR) represents the interest rate at which the NPV of the investment equals zero. This tool is used to determine which financial decision yields the highest profit. A project with an IRR greater than the discount rate is considered profitable.
The investment payback period (DPB) determines how long it takes for an investment to pay back from its net cash proceeds. The lower the DPB figures, the faster the investment returns and grows.
When it is necessary to resort to feasibility indicators
Net present value is used for long-term investments when it is necessary to take into account the change in the value of money over time. Internal rate of return is useful when evaluating projects with applied cash flows or for comparison with a discount rate representing the cost of capital. Investment payback period indicators are used to determine short-term financial investments when it is important to know after what period they will begin to pay off.

Benefits for Business
Investment feasibility metrics provide valuable tools for businesses to evaluate and make decisions regarding projects. This process assists businesses in making informed decisions by selecting directions with the highest profit potential, thereby promoting the sustainable development of the company. The implementation of investment feasibility metrics also offers the following advantages to the company:
- NPV, IRR, and DPB provide quantitative data that help businesses make well-informed decisions regarding which projects to finance.
- Feasibility analysis helps determine which projects yield the highest return on invested capital, optimizing resource allocation and focusing on the most profitable opportunities.
- Using these metrics data helps prevent financial losses associated with unprofitable projects, enhancing business stability and ensuring reliable financial planning and risk management.
- Increased investor interest in projects with high NPV, IRR, and DPB metrics.

Implementing investment feasibility indicators in practice requires planning and an adequate approach. This process consists of the following steps:
- Conducting staff training on NPV, IRR, DPB indicators.
- Choosing the right tools, for example Microsoft Excel program can be useful.
- Compiling a professional model for investment projects.
- Analyzing and comparing the feasibility indicators of different projects to select the best one.
