Major Direct (“Mandatory”) Spending Programs

The largest block of federal spending — about 60% — is called “direct spending” because the outlays flow directly from legal obligations of the federal government established in authorizing laws. Direct spending is also referred to as “mandatory spending” because it is mandated by legal obligations written into law (such as Social Security benefits).
