The federal "sibling discount" in college financial aid — which previously lowered a family's expected contribution when multiple children were enrolled simultaneously — has been eliminated with the introduction of the Student Aid Index (SAI).. According to the source article, the new formula no longer accounts for the number of family members in college, leaving middle-income households particularly exposed to a sudden, unbudgeted financial burden. The change means that parents who planned for overlapping college years must now navigate a system that offers no automatic federal relief for the added strain.

The SAI Formula That Erased the Sibling Adjustment

Under the old Expected Family Contribution (EFC) system, the federal formula included a clear buffer: when two or more children were enrolled simultaneously , the contribution was divided among them, effectively reducing the amount expected from each. The SAI, introduced as part of the FAFSA Simplification Act, removed that calculation entirely. As the source article explains, the SAI now treats each student independently, regardless of how many siblings are in college at the same time. This change has transformed the way need is calculated — and for many parents, it has dramatically increased the out-of-pocket cost for each child .

Two Housing Contracts and Two Meal Plans: The Compounding Cost of Multiple Enrollments

The financial impact goes far beyond tuition. The report emphasizes that when a family has two students in college simultaneously, they face a multiplier effect across every major expense: separate housing contracts,two meal plans, doubled fees, and two sets of textbooks, laptops, and specialized software. Transportation and health insurance also add up. For families who saved under the assumption that the sibling discount would ease the burden once the second child enrolled, the new reality is a "jarring awakening," the article states. The absence of the federal adjustment means that diligent savers may deplete their funds faster than anticipated.

The Missing National Count: How Many Middle-Income Families Are Affected?

The source article does not provide precise data on how many households are currently feeling the sting of the SAI change. This is a notable gap: without a national count of families with multiple children in college, the true scale of the disruption remains unclear. It is also unknown how many colleges have responded by adjusting their own institutional policies. The report notes that some private schools using the CSS Profile may still exercise discretion in awarding their own grants, but whether those adjustments are widespread or rare is not specified. These unanswered questions leave parents in a state of uncertainty as they plan for overlapping enrollments.

Pressing for Institutional Relief: The Appeal and the CSS Profile Workaround

With the federal safety net gone, the source article argues that families must adopt a proactive, even aggressive, approach to financial aid. Parents should cotact financial aid offices well before committing to a college and ask specifically about any institutional sibling grants. The article advises filing a formal appeal — known as a professional judgment review or special circumstances request — to make the case that the SAI formula fails to capture the true cost of supporting mutliple children. According to the report, families who provide detailed documentation of expenses may be able to secure additional institutional funding. The key, the article concludes, is to shift from expecting an automatic discount to actively negotiating on behalf of each child's education.
