Introduction

The Seer-ROI is a powerful tool that can be used for estimating the software development process. The tool can estimate all parts of the process such as labor, stuffing or maintenance cost. Nowadays, running a project without making ROI analyse on it is very risky for companies because of the rapidly changed economical situation of the world.

Behind the idea of using ROI software is increasing the cost/benefit efficiency. Since the common purpose of the corporates is lowering the cost and increasing the benefit of the project, ROI software is on of the most important tools that should be used before spending money and time on it. The company can lead the project according to the resulting analysis, including histograms, pie charts and gain-loss graph with the related data. A performance measure used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. To calculate ROI, the benefit (return) of an investment is divided by the cost of the investment; the result is expressed as a percentage or a ratio.

The return on investment formula:

In the above formula "gains from investment", refers to the proceeds obtained from selling the investment of interest. Return on investment is a very popular metric because of its versatility and simplicity. That is, if an investment does not have a positive ROI, or if there are other opportunities with a higher ROI, then the investment should be not be undertaken.
