Abstract: Software Cost Estimation is essential for efficient control and management of the whole software development process. Today, Constructive Cost Model (COCOMO 11) is very popular for estimating software cost. In Constructive Cost Model lines of code and function, points are used to calculate the software size. Actually, this work represents the implementation stages but in early stages in software development, it was not easy to estimate software cost. The entity relationship model (ER Model) is very useful in requirement analysis for data concentrated systems. This paper highlights the use of Entity Relationship Model for software cost estimation. Pathway Density is ushered in. By using the Pathway Density and other factors, many regression models are built for estimating the software cost. So in this paper, Entity Relationship Model is based on estimated cost of software. [Journal of
