Compare College OffersThe Student Aid Index, or SAI, is a FAFSA result used in the financial aid process.
It is not the amount a family will definitely pay. It is one input schools use when building a financial aid offer, along with cost of attendance, grant aid, scholarships, loans, work-study, and school policy.
That distinction matters because families can misunderstand the SAI as a bill. The real planning number is the net price after gift aid and the borrowing needed to cover the rest.
What does SAI replace?
SAI replaced the older Expected Family Contribution language used in prior FAFSA cycles.
The name change matters because many families heard Expected Family Contribution and assumed it was the exact amount they would pay. SAI is still easy to misunderstand, but it is better thought of as a financial-aid formula result rather than a family invoice.
A school can use the SAI to help determine eligibility for need-based aid, but the final offer depends on the school and available aid.
Why can two schools use the same SAI differently?
Schools have different costs and different aid budgets.
A family can have the same FAFSA result at two colleges but receive very different aid offers because tuition, housing, institutional grants, merit aid, and unmet need vary.
That is why comparing only SAI or sticker price can mislead families. Compare the actual offer letter and the remaining out-of-pocket cost.
What should families calculate next?
Start with cost of attendance, then subtract grants and scholarships that do not need to be repaid.
The remaining amount is the gap that must be covered by savings, current income, student work, federal student loans, parent loans, private loans, or a lower-cost option.
Use the calculator to compare the real net price and debt plan, not just the FAFSA result.
The Bottom Line
SAI matters, but it is not the final answer.
Use it as one part of the financial aid picture, then compare actual net price, gift aid, loans, and monthly repayment risk before choosing a school.
