Cost analysis can help improve education decision-making and policy. There are different types of costs to consider: individual/private costs borne by students and families; institutional/public/social costs borne by governments and institutions; and opportunity costs of forgone earnings. Costs can be classified as fixed, variable, recurring, non-recurring, current, or capital depending on how they change with activity levels or over time. Considering all relevant cost types helps provide a comprehensive understanding of the full social costs of education. Unit cost analysis examines costs per student, graduate, or other educational output to help evaluate efficiency and inform planning.
