Cost-effectiveness is a concept used to evaluate the efficiency of a program, project, or intervention by comparing its costs to its outcomes or benefits. It is a way to determine if the resources invested are yielding the desired results. In essence, it asks whether the benefits achieved are worth the expenditure. This differs from cost-benefit analysis, which attempts to monetize all costs and benefits, as cost-effectiveness often focuses on non-monetary outcomes, such as lives saved or improved health status.

The calculation of cost-effectiveness typically involves dividing the total cost of an intervention by its measured effect. The resulting figure represents the cost per unit of outcome. For example, in healthcare, cost-effectiveness might be expressed as the cost per life-year gained or the cost per case of disease prevented. This metric allows for comparisons between different interventions that aim to achieve similar objectives. When evaluating options, the intervention with the lower cost per unit of outcome is generally considered more cost-effective.

Several factors can influence cost-effectiveness, including the accuracy of cost estimates, the reliability of outcome measures, and the time horizon over which costs and benefits are considered. It is a valuable tool for decision-making, particularly when resources are limited and choices must be made about where to allocate them for maximum impact. Policymakers, managers, and researchers frequently employ cost-effectiveness analysis to inform their strategies and ensure efficient use of public and private funds.
