Expected Family Contribution (EFC) Estimator

The Student Aid Index (SAI) — formerly called Expected Family Contribution (EFC) — is the number FAFSA calculates to determine your federal financial aid eligibility. A lower SAI means more need-based aid. Understanding the formula lets you make timing and planning decisions that legitimately reduce your SAI before filing. This estimator uses the federal methodology from the Higher Education Act to compute your SAI and show you which factors have the largest impact.

The full calculator is in active build. When it ships, you'll be able to model:

  • Student dependency status (dependent vs independent)
  • Parent adjusted gross income (AGI) for base year
  • Parent total assets (savings, investments, 529 — excluding primary residence and retirement)
  • Student income and assets
  • Family size and number of household members in college
  • State of residence (for state aid programs)
  • Enrollment year (determines which tax year is the base year)
Results preview

Estimated SAI (Student Aid Index). Parent contribution and student contribution components. Maximum Pell Grant eligibility. Need calculation for sample schools at different cost of attendance levels. Sensitivity analysis: how much SAI changes with $5,000 more/less in income or assets. Planning timeline: base year calendar for future enrollment years.

This panel reserves its final height now so there's zero layout shift when the live tool replaces the placeholder.
