Federal Science Budget Tracker

FYI’s Federal Science Budget Tracker provides up-to-date information on appropriations proposals and outcomes for agencies that fund the physical sciences. For each agency, you can click through to a page with program-level budget details, a timeline of actions, and historical budget data.

These trackers are updated as spending proposals become available and legislative action occurs. Previous-year spending levels are also available back to fiscal year 2017.

Note: We are in the process of upgrading the tracker to better display historical data. However, we caution that figures for many agency programs are not always comparable over time due to budget restructurings and reallocations of funds. There are also often differences between how budget figures are reported by agencies versus how they are reported by Congress.

Note for fiscal year 2027: Figures marked “final” for fiscal year 2027 in the charts below reflect the stopgap spending bill that extended federal funding until Dec. 11, 2026.

The stopgap bill provides level funding for most agencies and programs for about a quarter of fiscal year 2027. We have presented the full-year equivalent of that funding to make it easier for users to compare the funding provided by the stopgap bill to prior year appropriations.

The values for 2027 may change if Congress enacts traditional appropriations later this year. Additionally, the stopgap bill gives agencies some latitude to reposition funds within their budget. As a result, funding for specific programs may change due to unilateral agency decisions.
