Cost benefit analysis is a systematic process for calculating and comparing benefits and costs of a project. A cost benefit analysis finds, quantifies, and adds all the positive factors (the benefits). Then it identifies, quantifies, and subtracts all the negatives (the costs). The difference between the two indicates whether the planned action is advisable. The real trick to doing a cost benefit analysis well is making sure you include all the costs and all the benefits and properly quantify them.
