A software metric is the measurement of a particular characteristic of a software program. These metrics are very useful for optimizing the performance of the software, managing resources, debugging, schedule planning, quality assurance and periodic calculation of software metrics increases the success rate of any software project. Therefore, a software metrics tool is developed in this research which provides an extensible way to calculate software metrics. The tool developed is a web-based application which has the ability to calculate some of the important software metrics and statistics as well. It also provides a functionality to the user to add additional metrics and statistics to the application. This software metrics tool is a language-dependent tool which calculates metrics and statistics for only C# source files.
