Budget Projection Sources


NIH sets the Predoctoral stipend level.

Institutional Allowance:

NIH sets the Institutional allowance.

Tuition and fees calculation:

Tuition and Fees Chart from Graduate Division T/F page. Everything except for the health insurance fee is included in the total of tuition and fees. Health insurance is not an allowable cost for the tuition and fees request for NIH. If awarded, health insurance fees may be paid out of the institutional allowance.
The current year’s tuition and fees serve more as a jumping off point because if awarded these students will not be paying for tuition and fees this year but next year so the 10 percent increase applies to the first year of requested tuition and fees.
