Just remember, they are not looking, for example, at this year’s income - so even if she makes less, that won’t be seen til two years out. So the 2026/27 FAFSA is using the 2024 income.
The other thing is - the privates use the CSS form - so your SAI is a federal index but based on her assets (home, investments, etc.) they may want more $$.
Best of luck.
