* FY2026 is year-to-date — the fiscal year is still in progress, so its total is still filling in. The striped band and dashed line mark that provisional stretch.
How to read these numbers
- Committed, not paid
Every figure is money this agency committed — legally promised by signing a contract or awarding a grant — counted in the year each action happened, not cash out the door.
- From FY2018 on
Agency pages start at fiscal year 2018, the first year of complete federal-assistance reporting. Earlier years aren't shown rather than shown wrong.
- Awards, counted once
An award count is the number of distinct awards with at least one action that year — each counted once, however many times it was amended.
- Benefits show as programs
Medicare, Social Security, and other direct payments to individuals are aggregated by the government, so under Where the money goes they appear as the program, not a named recipient.
- The colored bars
Every bar on this page splits by how the money moves:
