Federal Student Aid describes SAI as an index used by schools to determine aid eligibility; it is not a bill or the amount your family must pay. This tool applies the simple planning relationship cost of attendance − SAI − known aid. Your school may use professional judgment, different budgets, loans, work-study or other adjustments.
