NIH Appropriations

NIH funding is vital to the careers of many AAI members and the biomedical research enterprise as a whole.

The $34.1 billion NIH budget for fiscal year (FY) 2017 funds more than 300,000 extramural scientists at 2,500 universities, medical schools, and research institutions. 

Approximately 80% of the NIH budget is awarded to extramural scientists; about 10% supports the work of NIH's nearly 6,000 intramural scientists.

NIH funding has a huge impact on the advancement of biomedical research and on the economy (local, state, national, and international).


In May 2017, Congress passed, and President Donald Trump signed into law, an omnibus appropriations bill for FY 2017 that included a $2 billion (6.2%) funding increase for NIH, bringing the total NIH budget to about $34.1 billion. All NIH Institutes and Centers received additional funding, including an increase of about $270 million (6%) for the National Institute of Allergy and Infectious Diseases (NIAID), a $174 million increase (3.4%) for the National Cancer Institute (NCI), and a $448 million increase for the National Institute on Aging (NIA) ($400 million of which is earmarked for research on Alzheimer’s disease). This is the second consecutive year that NIH has received a $2 billion funding increase, and reflects the strong bipartisan support that NIH enjoys in Congress.  This year’s increase is particularly noteworthy as it was provided despite a recommendation by President Trump to cut the NIH budget by $1.2 billion.
