Every immigrant without a high School diploma costs the US $231,000, in net present value, according to a report on “The Economic and Fiscal Consequences of Immigration” from the National Academies of Sciences, Engineering, and Medicine:
On average, a nonelderly adult immigrant without a high school diploma entering the U.S. will create a net fiscal cost (benefits received will exceed taxes paid) in both the current generation and second generation. The average net present value of the fiscal cost of such an immigrant is estimated at $231,000, a cost that must be paid by U.S. taxpayers.
However, a rough estimate of the future net outlays to be paid by taxpayers (in constant 2012 dollars) for immigrants without a high school diploma appears to be around $640,000 per immigrant over 75 years. The average fiscal loss is around $7,551 per year (in constant 2012 dollars).
Slightly more than 4 million adult immigrants without a high school diploma have entered the U.S. since 2000 and continue to reside here. According to the estimates in the National Academies report, the net present value of the future fiscal costs of those immigrants is $920 billion.
This means government would have to immediately raise taxes by $920 billion and put that sum into a bank account earning 3 percent plus inflation per year to cover the future fiscal losses that will be generated by those immigrants.
To cover the future cost, each taxpaying U.S. household, on average, would have to pay an immediate lump sum of over $10,000. Costs would go up in the future as more than 200,000 additional adult immigrants without a high school diploma arrive in the country each year.
