An infinitesimal amount when compared to the overall federal spending. The government currently spends about 582 million per year on refugee resettlement. Total government spending in 2016 was approximately 3.54 trillion. Thus, the current money spent on refugee resettlement is less than .02% (not 2%, not 0.2%, but .02%) of spending in 2016. The percentage is similar for the last five years, except in 2012 when even less, .008%, of government spending went toward refugee resettlement.
As a point of comparison, if you spent approximately $50,000 per year on your household expenses, it would be like spending less than $10 of that $50,000 to give thousands of people safety, opportunity, and life (survival).
Or, to put it another way, there are approximately 122 million taxpayers in the U.S. If we divide the amount of money spent on refugee resettlement by the number of tax payers, each tax payer contributes less than $5 to refugee resettlement each year.
