Understanding USAspending.gov Data
A guide to reading and interpreting the federal spending data that powers this site.
Last updated: February 1, 2025
About USAspending.gov
USAspending.gov is the official source for federal spending data, maintained by the U.S. Department of the Treasury. It tracks trillions of dollars in federal spending across all agencies.
What Data Is Available
- --Award-level data: Individual contracts, grants, loans, and other financial assistance
- --Agency spending: Budget authority, obligations, and outlays by agency
- --Recipient data: Which companies and organizations receive federal money
- --Geographic data: Where federal money is spent, by state and congressional district
Data Limitations
Timing: Agencies report spending data with a lag. Some data may be days or weeks behind actual spending activity.
Completeness: Not all federal spending appears on USAspending.gov. Some classified defense spending and certain types of financial transactions may not be included.
Accuracy: While Treasury works to improve data quality, some records contain errors in reporting — incorrect amounts, misclassified categories, or incomplete descriptions.

- --Modifications to existing awards appear as separate transactions
