In 2020, CBO estimates a deficit of $1.0 trillion, or 4.6 percent of gross domestic product (GDP). Under current law, the projected gap between outlays and revenues increases to 5.4 percent of GDP in 2030. Federal debt held by the public is projected to rise over the coming decade, from 81 percent of GDP in 2020 to 98 percent of GDP in 2030. It continues to grow thereafter, in CBO’s projections, reaching 180 percent of GDP in 2050, well above the highest level ever recorded in the United States.
