In 2021, U.S. consumers spent an average of 10.3 percent of their disposable personal income on food—divided between food at home (5.2 percent) and food away from home (5.1 percent). The share of disposable personal income spent on total food has trended downward since 1961—driven by a decline in share of income spent on food at home.
