Cost-Benefit Analysis

ConceptualFrameworksFinance

Definition

Cost-Benefit Analysis: Cost-benefit analysis systematically compares the costs and benefits of a decision, project, or policy. By quantifying both sides in comparable terms (usually monetary), CBA reveals whether benefits justify costs and enables comparison between alternatives. It forces explicit consideration of trade-offs.

Example Usage

CBA showed our custom integration would cost $200K to build but save customers $500K annually. The 2.5x return justified the investment.

Common Misconceptions

Only count financial costs and benefits. Include time, opportunity cost, risk, and intangible factors.
All benefits are measurable. Some benefits are qualitative; acknowledge them even if not quantified.
CBA is always worth doing. For small decisions, intuition is faster; reserve CBA for significant choices.
