Building a wall on the southern U.S. border could save taxpayers four to five times its cost over the next 10 years, a new report by the Center for Immigration Studies (CIS) shows.

Using National Academy of Science (NAS) and Department of Homeland Security (DHS) data, the study looks at the lifetime net financial drain (taxes minus services used) of each illegal alien entering the country.

Given the $12-15 billion cost of the border wall and assuming 1.7 million illegal crossings without the wall over the next 10 years:

  • Each illegal is a lifetime net cost to taxpayers of $74,722
  • If the wall cut illegal entries in half (850,000), the wall would save $64 billion over ten years
  • The wall would pay for itself in two years (1.9-2.2 years, depending on cost)
  • It would save taxpayers 4-5 times its cost over 10 years

If the wall stopped only 9-12% (160-180,000) of illegal crossing over the next decade, a $12-15 billion wall would pay for itself in ten years

Factoring in the average cost of an illegal alien’s U.S.-born children, the net financial cost taxpayers would have to absorb is $94,931. If the wall stopped only 9% (160,000) illegal crossing, a $12,000,000 wall would still pay for itself in about eight years.
