Software cost estimation is accounted as an important factor while making estimations in Software Engineering. There is no simple way to make an accurate estimate of the effort required to develop software systems because of many reasons like unclear user requirements, lack of knowledge on new technology, changing technology requirements and not considering the reusable component cost. In this paper an attempt is made to use swarm particle optimization to eliminate unnecessary entries from database. This approach gives a good optimised result and proved to be the best cost estimation.
