Because mandatory programs often dominate farm bill 
policy and the debate over the farm bill budget, the rest of 
this document focuses on mandatory spending. 
Importance of Baseline to the Farm Bill 
The Congressional Budget Office (CBO) develops the 
budget baseline under various laws and follows the 
supervision of the House and Senate Budget Committees. 
The CBO baseline is a projection at a particular point in

which proposed changes in law are measured.

When a new bill is proposed that would affect mandatory 
spending, the cost impact (score) is measured in relation to 
the baseline. Changes that increase spending relative to the 
baseline have a positive score; those that decrease spending 
relative to the baseline have a negative score. 
Most of the major farm bill provisions such as the farm 
commodity programs and nutrition assistance have 
baseline. However, 39 programs that were authorized in the 
2014 farm bill with mandatory funding do not have a 
continuing baseline (see CRS Report R44758, Farm Bill 
Programs Without a Budget Baseline Beyond FY2018). 
CBO’s April 2018 Baseline 
The mandatory spending baseline for farm bill programs 
contains $867 billion over FY2019-FY2028, 77% of which
