2026-27 FAFSA Financial Aid Estimator: What's Your SAI?
The Student Aid Index (SAI) is the number colleges use to calculate your eligibility for need-based financial aid. A lower SAI means more aid. For families earning $150K–$400K, the SAI typically lands between $20,000 and $90,000 — high enough that need-based grants are limited at lower-cost public schools, but often meaningful at high-sticker private colleges that meet 100% of demonstrated need.
How the SAI formula works
The 2026-27 SAI has two components: parent contribution from income and parent contribution from assets. These are added together. Here is the full calculation chain.
Step 1: Build Available Annual Income (AAI)
Starting with your 2024 AGI, the formula subtracts five items to produce Available Annual Income (AAI):
- Federal income taxes paid (line 24 of Form 1040)
- FICA taxes — 7.65% of wages up to the 2024 Social Security wage base ($168,600 per earner), plus 1.45% Medicare above that
- State and other tax allowance — varies by state, roughly 3–5% of income (this calculator uses 4% as a mid-range default)
- Employment expense allowance — approximately $4,400 for two-earner households; recognizes the real cost of both parents working
- Income Protection Allowance (IPA) — shields a baseline living standard from assessment; $44,880 for a family of 4 in 2026-271
Step 2: Apply the income assessment rate schedule
The AAI is assessed at progressive rates from 22% to 47%. These brackets apply to AAI (the income after all deductions above), not to gross income — so even high-income families benefit from the full IPA and allowances before the rate kicks in.1
| Available Annual Income (AAI) | Income contribution formula |
|---|---|
| Below −$8,500 | −$1,870 |
| −$8,500 to $21,800 | 22% of AAI |
| $21,801 – $27,300 | $4,796 + 25% of amount over $21,800 |
| $27,301 – $32,800 | $6,171 + 29% of amount over $27,300 |
| $32,801 – $38,400 | $7,766 + 34% of amount over $32,800 |
| $38,401 – $43,900 | $9,670 + 40% of amount over $38,400 |
| Over $43,900 | $11,870 + 47% of amount over $43,900 |
Step 3: Add the asset contribution
Parent-owned assets are assessed at a flat 5.64%. Every $100,000 in parent assets adds $5,640 to the SAI. Critically, the Asset Protection Allowance (which used to shelter up to $84,000 in assets at its 2009 peak) was reduced over the years and is now $0 for 2026-27 — every dollar in parent assets is counted at the full 5.64% rate.3
Three 2026-27 formula changes that matter
1. No addback for pre-tax retirement contributions
Under the old EFC formula, contributions to 401(k), 403(b), and pension plans were added back to income — meaning a family contributing $49,000/year to two 401(k)s saw their FAFSA income rise $49,000 above their actual AGI. The 2026-27 formula eliminates this addback entirely. Your AGI (which is already reduced by pre-tax contributions) is used directly. A family in the 22% income bracket can reduce their SAI by $10,000–$20,000 per year through full 401(k) maximization.1
2. No sibling discount — each student calculated independently
The old formula divided the SAI by the number of college students in the household simultaneously. Two kids in college at the same time used to cut each student's SAI roughly in half. That adjustment is gone. Under 2026-27 rules, each student's SAI is calculated independently from the full household income and assets, regardless of how many siblings are enrolled concurrently.2 For families with children close in age, this is the largest structural change in the new FAFSA.
3. Small business and farm exclusion (new)
Family-owned businesses with 100 or fewer employees, farms on which the family resides, and commercial fishing businesses are now excluded from parent assets. If you own a qualifying small business, leave its value out of the assets input above.2 The IRS-based valuation rules apply — consult a FAFSA strategist if your business is a meaningful share of household net worth.
SAI vs. net price: what colleges actually charge you
Your SAI is an input to each school's financial aid calculation — it is not a bill. How your SAI translates to actual out-of-pocket cost depends entirely on the school:
- Need = COA − SAI. Each school's Cost of Attendance (tuition + fees + room + board + estimated personal expenses) minus your SAI gives your "demonstrated need." If your SAI exceeds the COA, your need is $0 at that school.
- Meeting 100% of need vs. not. High-endowment private colleges (many Ivies, liberal arts colleges, and selective universities) publish policies that meet 100% of demonstrated need with grants — no loans, no work-study requirement. A $68,000/year school that meets full need can cost the same as a $32,000/year state school for families with significant demonstrated need.
- Merit aid is separate. Merit scholarships are not need-based and don't interact with the SAI formula. A family with a high SAI can still receive substantial merit awards at schools eager to attract strong applicants.
| SAI | In-state public (~$32,200/yr) | Private nonprofit (~$68,100/yr) | Need-based Pell eligibility |
|---|---|---|---|
| $0 or below | ~$32,200 need | ~$68,100 need | Max $7,395/yr |
| $15,000 | ~$17,200 need | ~$53,100 need | Partial Pell possible |
| $30,000 | ~$2,200 need | ~$38,100 need | None |
| $50,000 | Zero need | ~$18,100 need | None |
| $75,000+ | Zero need | Zero need at most schools | None |
2026-27 COA estimates based on College Board 2025-26 data adjusted for ~4% annual cost growth. Aid awards depend on individual school policies. High-endowment schools may meet 100% of need with grants; others fill with loans.
Income Protection Allowance by family size (2026-27)
| Household size | IPA (2026-27, 1 student in college) |
|---|---|
| 3 people (2 parents + 1 child) | $37,890 |
| 4 people (2 parents + 2 children) | $44,880 |
| 5 people | $51,870 |
| 6 people | $58,860 |
| 7 people | $65,850 |
| Each additional person | +$6,990 |
