How much does UBI cost?

I just completed some simple, “back-of-the-envelope” estimates the net cost of a UBI set at about the official poverty line: $12,000 per adult and $6,000 per child with a 50% “marginal tax rate.” They are in a paper entitled, “the Cost of Basic Income: Back-of-the-Envelope Calculations.” It’s currently under peer-review at an academic journal and available in un-reviewed form on my website.

Here are some of its most important findings:

  • The net cost—the real cost—of a roughly poverty-level UBI is $539 billion per year, less than 16% of its often-mentioned but not-very-meaningful gross cost ($4.15 trillion), less than 25% of the cost of current U.S. entitlement spending, less than 15% of overall federal spending, and about 2.95% of Gross Domestic Product (GDP)
  • This $539 billion UBI would drop the official poverty rate from 13.5% to 0%, lifting 43.1 million people (including about 14.5 million children) out of poverty.
  • This UBI will be a net financial benefit to most families with incomes up to $55,000, making it an effective wage subsidy (or tax cut) for tens of millions of working families.
  • The average net beneficiary of this UBI is a family of about two people making about $27,000 per year. The family’s net benefit from the UBI would be nearly $9,000 raising their income to almost $36,000.
  • Lowering the marginal tax rate to 35% would spread the benefits of the UBI program to more of the middle class while increasing the cost to $901 billion.
  • The cost of a UBI of $20,000 per adult and $10,000 per child is $1.816 trillion per year, less than 85% of total entitlement spending, less than 45% of total federal spending, and less than 10% of GDP.

    415 trillion is a typo.
    Should be 4.15 trillion. Otherwise, nice summary.

    It kind of makes everyone that receives it, a slave to government. Does it not? I can see it. Everyone gets chipped. All currency goes digital (no more cash). The holdouts either starve or are rounded up and done away with. The masses will swallow everything government feeds them, and label the resisters, terrorists. Can you think of a better scenario to have the entire world involved in civil war at the same time? Because that’s what will happen. There are people everywhere that just will not go along with this.

      @Adam….how would it make people slaves giving them a floor level subsistence income? if anything those people are slaves now and poorly treated at that. If everyone below the $50k a year had $1k a month they get at least have food and a place to live, they would still need a job to get the rest of things people usually want to have like a car or the newest phone.

      But lets say the worst case scenario happens like you stated and people get cut off all of a sudden, then guess what, they are no worse off then than they are now. But while they were getting a UBI they had a better quality of life AND the opportunity to better themselves by starting a business or getting a higher education while not being at or below poverty level.

      Besides, all businesses want customers to spend money on them. It would be a boon to the economy and to businesses profits. The free (but regulated) markets will keep prices in check as well as improve the well being of society in general. UBI is not a silver bullet to solve all problems but it will help to move us in that direction.

      “Starve to death or become a wageslave” is fine for capitalism, but people giving you things is slavery! I don’t understand this capitalism double-think.

    How is the net cost only 13% of the gross cost? Where do you account for landlords increasing rent? You can’t cap rent because that would then trigger a shortage of low income housing.

      This is only a static analysis. It does not look at how anyone will change their behavior in response to UBI, not workers, employers, consumers, landlords, or anyone else. It is the jumping off point for analyses that look at those effects.

      Certainly UBI would cause an increase in rent in neighborhoods where net beneficiaries live and a decrease in rent where net contributors live. So it would reduce the value of the UBI to net recipients. That’s a bad thing. But it would also reduce housing segregation, and that’s a good thing.

      There’s any easy way to solve the bad thing: use rent taxes to finance the UBI. The increased rent would automatically generate increased revenue, which could be added to the UBI. Then you get the decrease in housing segregation without the decrease in net benefit to net beneficiaries

    Giving a ubi to children just exacerbates the problem of the least qualified people having children to receive benefits. Perhaps there are other things to spend the money on like public education, free college and training, to encourage people to have their lives sorted out before becoming parents. There has to be some opportunity cost or we will have an ever growing population of people who regard free handouts as the purpose of life.

    What abouy all the people who will try to immigrate into the country? A more modest first step that we can also encourage other nations to adopt is a private supplememtal social security IRA that can be withdrawn from when needed, and passed on after death. It would end the worst most desperate poverty. Also giving UBI to children is worse at breeding bastardd than AFDC, that money should go to schools, teachers, and healthcare.
