In 2016, 54 percent of American workers ended 2016 with unused vacation days, amounting to a total of 662 million vacation days. Unused vacation days cost the U.S. economy $236 billion in 2016, due to lost spending. That spending would have supported 1.8 million American jobs and generated $70 billion in additional income for American workers. If the 54 percent of workers who left time unused in 2016 took just one more day off, it would drive $33 billion in economic impact. (The State of American Vacation 2017)
