Expected Family Contribution (EFC) Calculator

Enter your family's financial details — household size, parent income, student income, assets, and dependency status — to estimate your Expected Family Contribution (EFC), now called the Student Aid Index (SAI). Your EFC/SAI helps colleges determine how much federal financial aid you may qualify for each academic year.

Most undergraduates under 24 are considered dependent unless married, a veteran, or legally emancipated.

Frequently Asked Questions

What is the Expected Family Contribution (EFC)?

The EFC (now officially called the Student Aid Index, or SAI) is a number calculated from your FAFSA that colleges use to determine your eligibility for federal financial aid. It represents how much your family is expected to contribute toward college costs for one academic year. A lower EFC means you may qualify for more need-based aid.

What is the difference between EFC and SAI?

The Student Aid Index (SAI) replaced the Expected Family Contribution (EFC) starting with the 2024–25 FAFSA. The SAI uses a revised formula and can now be a negative number (as low as -$1,500), indicating even greater financial need. Most schools still use the terms interchangeably in conversations, but the official FAFSA now uses SAI.

Does the EFC represent what I must pay out of pocket?

Not necessarily. The EFC/SAI is a measure of your family's financial strength, not a bill. Colleges use it to determine your financial need (Cost of Attendance minus EFC), but most schools do not meet 100% of demonstrated need. Your actual out-of-pocket costs depend on the specific aid package each college offers.

What income and assets are included in the EFC calculation?

The EFC formula considers parent and student adjusted gross income (AGI), untaxed income, federal taxes paid, and non-retirement assets like savings, checking, and investment accounts. It excludes retirement accounts (401k, IRA), the value of your primary home, and small family businesses with fewer than 100 employees.

How does having more than one child in college affect the EFC?

When multiple family members attend college simultaneously, the parent contribution portion of the EFC is divided among the number of college students. This can significantly reduce each student's individual EFC, potentially increasing eligibility for need-based aid.

Why does parent age affect the EFC calculation?

Parent age determines the 'asset protection allowance' — the portion of parent assets sheltered from the formula. Older parents have a higher allowance because they have less time to rebuild savings before retirement. This reduces the countable parent assets and may lower the EFC.

How accurate is this EFC calculator?

This calculator provides a close estimate based on the federal EFC/SAI methodology, but the official figure is determined by the FAFSA processor using verified data. Differences can arise from rounding, state allowances, and specific line-item details on your tax return. Always submit the FAFSA for your official SAI.

Can an independent student have a lower EFC than a dependent student?

Yes. Independent students' EFC is based only on their own (and their spouse's) income and assets — parent financials are not considered. For students with low personal income, this often results in a lower EFC and greater financial aid eligibility compared to dependent students with higher-income parents.
