COST-BENEFIT ANALYSIS

Back to Glossary

Definition

A decision framework that compares the total expected costs and benefits of an action to determine net value.


Summary

Cost-Benefit Analysis (CBA) is a systematic approach to evaluating decisions by weighing all positive outcomes (benefits) against all negative outcomes (costs) in monetary terms. Think of it as creating a financial 'pros and cons' list where everything is converted to dollar amounts. The goal is to determine whether a project, policy, or decision will create more value than it costs. If total benefits exceed total costs, the action has a positive net present value and may be worth pursuing. This framework helps decision-makers compare different options objectively and allocate resources efficiently.

Usage Context

Understanding cost-benefit analysis is crucial when studying public policy evaluation, business decision-making, project management, and resource allocation. It's particularly important in economics, public administration, and business strategy courses where students learn to make data-driven decisions about investments, regulations, and organizational changes.

Common Confusions

  • Confusing cost-benefit analysis with simple budgeting or accounting
  • Forgetting to include opportunity costs or indirect effects
  • Not properly discounting future costs and benefits to present value
  • Mixing up cost-benefit analysis with cost-effectiveness analysis
  • Assuming all costs and benefits can be easily quantified in monetary terms
