How Much Would Universal Basic Income Cost? In July 2022, there were 164 million Americans in the labor force.7 FRED, Federal Reserve Bank of St. Louis. "Civilian Labor Force Level." A GBI of $12,000 per year ($1,000 per month) for each person in the labor force would cost $1.968 trillion per year. Many supporters argue that UBI would not need to be an addition to current welfare spending; a basic income would allow the government to cut redundant programs and reduce associated bureaucratic costs. A UBI would cost even more—with more than 300 million Americans, $12,000 per year would cost more than $3.6 trillion per year.
