Hyötyhaittasuhde

Hyötyhaittasuhde, often translated as cost-benefit analysis or benefit-cost ratio, is an economic and decision-making tool used to evaluate the desirability of a project or policy. It involves comparing the total expected benefits of an action to its total expected costs. The fundamental principle is that a project is considered worthwhile if the benefits outweigh the costs.

To calculate the hyötyhaittasuhde, all anticipated benefits are quantified in monetary terms and summed up. Similarly, all anticipated costs, including direct expenses, indirect costs, and potential negative externalities, are also monetized and totaled. The ratio is then typically expressed as the total benefits divided by the total costs. A ratio greater than 1 suggests that the benefits exceed the costs, making the project potentially a good investment. Conversely, a ratio less than 1 indicates that the costs are higher than the benefits.

This method is widely applied in various fields, including public policy, environmental management, business investment, and project appraisal. It helps decision-makers to objectively compare different options and allocate resources efficiently. However, the accuracy of a hyötyhaittasuhde analysis heavily relies on the reliability of the estimations for both benefits and costs, which can sometimes be challenging, especially for intangible or long-term effects. Despite these challenges, it remains a valuable framework for informed decision-making.
