What is the major predictor of funding for an agency?

The budget that the agency worked with the year prior to the current funding year is treated as the major predictor of funding for an agency.

Explanation:

Before funding any subordinate agency or an organization, the government takes reference from the agency's previous year budget and the funding previously done. It also looks into how the funds last sanctioned were utilized by the agency for the good of society. Based on this information, the agency is funded accordingly.
