Expected Family Contribution Calculator
The Number Financial Aid Offices Start From
Expected Family Contribution — now formally replaced by the Student Aid Index on the FAFSA but still widely used in scholarship and financial planning contexts — is the federal government's estimate of what a family can reasonably afford to pay toward college in a given year. Everything downstream, from need-based grants to subsidized loans, is calculated relative to this figure. This calculator applies a simplified approximation of the federal methodology to estimate it from income and assets.
The Formula
Student Contribution = 50% of Available Income + 20% of Assets
EFC = Sum of all contributions
Available income subtracts a protection allowance first — $15,000 for parents and $7,040 for a dependent student in this simplified model — before the percentage is applied. Assets are assessed at a flat rate with no protection allowance in this simplified version.
A Worked Example
| Component | Value |
|---|---|
| Parent Contribution (Income) | $11,000.00 |
| Parent Contribution (Assets) | $2,400.00 |
| Student Contribution (Income) | $480.00 |
| Student Contribution (Assets) | $600.00 |
| EFC | $14,480.00 |
Where This Calculation Matters
- Pre-FAFSA planning — getting a rough sense of EFC before completing the official application, to set expectations for financial aid.
- Financial need calculations — EFC is subtracted directly from cost of attendance to determine demonstrated financial need.
- Comparing schools — the same EFC applies across every school a student applies to, which is why net price can vary so much between schools with different costs of attendance.
- Savings and asset planning — because assets factor into the calculation, families sometimes adjust savings strategy years ahead of college with this in mind.
