Sub-agencies have no page of their own; each row opens its parent department, where the full sub-agency breakdown lives. Not every loaded year carries this breakdown.

Questions

Which federal sub-agency spends the most in FY2021?
Centers for Medicare and Medicaid Services, with $1.4T obligated in FY2021.
What counts as a sub-agency?
A sub-tier organisation reporting to a cabinet department or independent agency: a bureau, a military command, an administration. USASpending records both tiers on every award.
Where does this ranking come from?
It is computed from USASpending.gov award records, which are U.S. government works and in the public domain. Each figure is the sub-agency's obligations for FY2021. TheFiscalFinder does the ranking; the underlying figures are the government's own.
How many sub-agencies are shown?
The top 100 for FY2021. Each row opens that sub-agencie's own page, where the same money is broken out by year, by counterparty and by place.
Does a high position mean anything is wrong?
No. This is a description of where public money went in FY2021, computed from public records. It is not an allegation about anyone on it.

Why the labels? The graph is only worth anything if the links are trusted. Facts taken straight from a federal filing are ✓ from source; figures we calculate are ≈ computed; links we infer (corporate parents, districts, competitors, connections between records) are ≈ inferred, worded carefully, never asserted as fact and never a claim that one thing caused another.
