Research for the People

The NIH invests most of its $45 billion budget1 in medical research for the American people.

Over 84 percent2 of NIH’s funding is awarded for extramural research, largely through almost 50,000 competitive grants to more than 300,000 researchers at more than 2,500 universities, medical schools, and other research institutions in every state.

In addition, over 10 percent2 of the NIH's budget supports projects conducted by nearly 6,000 scientists in its own laboratories, most of which are on the NIH campus in Bethesda, Maryland. The remaining 6 percent2 covers research support, administrative, and facility construction, maintenance, or operational costs.
