By determining the value of only two variables, total efforts in person-months can be easily calculated. In basic cost estimation model the calculation is straightforward. Eventually, the final result is converted, through a standard conversion table to KLOC. Then this complexity is further adjusted via up to 14 different added-complexity factors.

In late models, complexity is determined firstly by inputs, outputs, interfaces, files and queries that the software system needs.
In early models, complexity means the project size or the program volume, which can be estimated merely via kilo lines of codes KSLOC. Though a vast body of knowledge exists today in respect to cost estimation techniques, most of these estimation techniques view cost as a function of complexity whether explicitly or implicitly. It has been proven that it is quite applicable to accurately and consistently predict development life cycle costs and schedules for a broad array of software projects. It s no wonder that so few companies realize that software cost estimating can be a science, not just an art. Cost Estimation Every year more projects are doomed by poor cost and schedule estimates than by technical, political or organizational problems. Relying on fixed costs as opposed to variable costs can boost the operating leverage while financing with high percentage on debtbased costs may boost the financial leverage.
4- Evaluating business performance: Cost is an essential ingredient to calculate many of the financial ratios explained above- uses to evaluate the financial performance for business firm 5- Leverage: Cost plays a significant role in both e the operating and the financial leverage in respect of risk and return. 3- Cost reduction: Since software engineering aims to provide cost-effective software solutions to business problems, many process and project related activities are designed or re-engineered to achieve the goal of cost minimization.

2- Feasibility Study: Making investment decisions regarding software projects requires full cost breakdown and nsequently, identified recurring and one time costs are then incorporated in a financial feasibility study in terms of cost-benefit analysis. 1 Cost Estimation Tutorial Cost is s strategic concept in software development for the following reasons: 1- Project management: Estimating cost is extremely crucial in carrying out project management activities such as scheduling, planning and control.
