TheCost costestimation ofin software engineering is mainlytypically fromconcerned developerwith timethe financial spend on the effort to develop and test the software, butthis can also beinclude fromrequirements review, maintenance, training, managing and buying extra equipment, servers and software. Many methods have been developed for estimating software costs for a given project.

*[[Proxy-based estimating]] (PROBE) (from the [[Personal Software Process]])

*[[Program Evaluation and Review Technique]] (PERT)

*[[Putnam_modelPutnam model]], also known as SLIM

*[[PRICE Systems]] Founders of Commercial Parametric models that estimates the scope, cost, effort and schedule for software projects.

*[[SEER-SEM]] Parametric Estimation of Effort, Schedule, Cost, Risk. Minimum time and staffing concepts based on [[Brooks's law]]

*[[Wideband Delphi]]

Most cost software development estimation techniques involve estimating or measuring software size first and then applying some knowledge of historical of cost per unit of size. Software size is typically sized in [[Source lines of code|SLOC]], [[Function Point]] or [[https://en.wikipedia.org/wiki/Burn_down_chartBurn down chart|Agile story points]].
