New student success interventions generate costs for colleges (for example, staff time and supplies). However, if they lead more students to remain enrolled, cause students to attempt more credits, and improve longer-term student outcomes, they can also generate tuition revenue and state funding (for public institutions in states that allocate funding based on enrollment, student outcomes, or both). Leaning on a robust body of evidence, this brief offers suggestions to policymakers, college administrators, and researchers for forecasting the financial impact of new interventions in postsecondary education, based on the interventions' costs and their ability to keep more students enrolled, generate tuition revenue and state funding, and improve outcomes.
