The importance of profitability in investment analysis

The profitability of an investment is an important indicator of the success of a company or project. In this article, we will take a closer look at the concept of return on investment and explain the differences between static and dynamic profitability.

What is return on investment?

Return on investment measures the relationship between the profit generated and the investment made. It is a key measure of the performance of an investment and is often used to evaluate business projects. The profitability of an investment can be calculated in various ways, including static and dynamic profitability.

Profit after interest

Profit after interest is an important component of return on investment. It indicates how much profit a company generates after deducting interest on borrowed capital. A high profit after interest indicates that an investment is profitable and helps to increase the value of the company.

Static profitability

Static profitability is a method for calculating the profitability of an investment in which only the current cash flows are considered. This method does not take into account the time value of money and can therefore lead to a distorted valuation, especially for long-term investments.

Difference between static and dynamic profitability

Static profitability:

Static profitability only takes into account the current cash flows of an investment and ignores the time value of money. This method is better suited to short-term investments where the cash flows are stable and predictable.


Dynamic profitability:

  • In contrast, dynamic profitability takes into account the time value of money and discounts future cash flows to their current value. This method enables a more accurate assessment of the profitability of an investment and is therefore more suitable for long-term investments.


The profitability of an investment is a decisive factor for the success of a company or a project. By analyzing profit after interest and using methods such as static and dynamic profitability, companies can make informed decisions about their investments and ensure long-term financial success. It is important to understand the differences between these two methods and apply the appropriate method according to the situation.
