Five years of reported amounts
Fiscal years end September 30. These are actual net outlays in nominal dollars, using the account structure in OMB’s FY2027 database.
| Fiscal year | Reported amount |
|---|---|
| 2021 | $1,180,000,000 |
| 2022 | $1,384,000,000 |
| 2023 | $1,616,000,000 |
| 2024 | $1,400,000,000 |
| 2025 | $1,531,000,000 |
FY2025 outlays were $131,000,000 higher than FY2024 (9.4%). Changes in account coverage, transfers and payment timing can affect the comparison.
Trace this figure to the source workbook
Use Sheet1, column “2025”, rows 3224, 3225. Sum these records and multiply by 1,000 to convert the published thousands of dollars to dollars. Each record is included once, including all grant, budget-status and spending-category splits within this function.
How these numbers work
FY2025 actual outlays from OMB’s FY2027 Public Budget Database. Published thousands of dollars are multiplied by 1,000. Records are grouped by agency, bureau and account across budget-status splits. Selected positive-outlay accounts appear once; zero-outlay accounts are omitted, and offsets and other accounts remain in the reconciliation. A running counter applies the historical pace and does not track actual transactions today.
Running amounts apply a constant historical pace: the reported amount divided by every second in FY2025 · October 1, 2024–September 30, 2025, multiplied by elapsed time in the selected range. They illustrate the flow; they do not track actual transactions today. Week starts Monday and YTD starts January 1, in UTC. Dollar increments show motion, not dollar-level measurement accuracy.
“Reported period” restores the original source amounts. This pace model freezes at 2027-01-01 unless a newer official snapshot is imported. These program snapshots have their own reporting periods and coverage, which differ from the national Treasury budget-function counter.
