Whitman College introduced a tuition cap tied to family income, the “10% Promise,” guaranteeing that tuition for covered students will not exceed 10% of family earnings over four years. The policy applies to first-year and transfer students starting fall 2027 and is designed to remove “secret formulas” from affordability expectations. Whitman’s model uses FAFSA submission plus a straightforward calculation based on parents’ adjusted gross income to determine the aid needed to reach the capped tuition. The plan targets tuition affordability specifically, while students remain responsible for housing, living, and other non-tuition costs. For higher education leaders monitoring affordability and net-price uncertainty, the policy is notable as a structural pricing commitment rather than a conventional discount strategy—and may influence competitive behavior among smaller selective institutions.
