A benefit cost analysis finds, quantifies, and adds together all of the positive impacts or benefits of a project. It then identifies, quantifies, and subtracts 
all the negative impacts or costs of a project or action.
The difference between the two determines whether or not the project or action is advisable.
It is a challenge to do a benefit cost analysis well, because it is difficult to include and quantify all the costs and benefits properly.
