How is a cost benefits analysis done step by step?

A cost-benefit analysis (CBA) is conducted in several key steps:

1. Identify the project or decision: Clearly define the scope and objectives of what you are analyzing.
2. List costs and benefits: Identify all potential costs (direct, indirect, and opportunity costs) and benefits (tangible and intangible) associated with the project.
3. Quantify costs and benefits: Assign monetary values to each cost and benefit, often using estimates or market values for intangibles.
4. Compare and analyze: Calculate the net present value (NPV) by subtracting total costs from total benefits, and assess whether the benefits outweigh the costs to inform decision-making.
