The Cost of Permanently Eradicating Poverty

There is no single agreed-upon price tag for permanently eradicating poverty, because "poverty" is defined and measured in different ways, and permanent eradication would require sustained investment over decades, not a one-time payment. However, economists and international organizations have produced some useful estimates.

1. The most commonly cited figure: ~$175–$200 billion per year

The World Bank and the United Nations have estimated that around $175–200 billion per year would be enough to bring everyone in the world above the extreme poverty line (defined as living on less than $2.15 per day in 2017 purchasing power parity). This would cover:

Direct cash transfers, food assistance, basic healthcare, basic education, and housing and sanitation improvements.

This is a rough estimate for extreme poverty only — not relative poverty, not lack of opportunity, and not long-term structural poverty in middle- and high-income countries.

2. U.S. domestic poverty: trillions over decades

If you mean poverty in the United States alone (using the U.S. poverty line, which is much higher than the global extreme poverty line), the cost would be much larger. For example:

The U.S. already spends about $1–1.5 trillion per year on welfare programs (Medicaid, SNAP, housing assistance, EITC, etc.).

Some estimates suggest that simply giving every American below the poverty line enough cash to close the poverty gap would cost an additional $200–300 billion per year.

But "permanent" eradication in a rich country would require addressing housing costs, healthcare, child care, education, and wages — likely requiring structural changes costing trillions over decades.

3. Broader global poverty (including moderate poverty)

If you use a higher global poverty line (e.g., $6.85/day, which is more appropriate for middle-income countries), the cost rises dramatically. One estimate from the Brookings Institution and others puts the global poverty gap at around $1–3 trillion per year when using higher standards.

4. Why "permanent" is so hard to price

The biggest challenge is that poverty is not a fixed stock that can be eliminated with a single payment. It is generated by ongoing systems:

Economic shocks (pandemics, recessions, climate change), conflict and displacement, inequality and labor market changes, lack of access to education and healthcare, and discrimination and political exclusion.

So “permanent eradication” would require not just cash transfers but sustained investment in institutions, infrastructure, governance, and climate adaptation — effectively a transformation of the global economy.

Bottom line

For extreme global poverty only: roughly $200 billion/year — less than 0.3% of global GDP, or about 3% of annual global military spending.

For a more comprehensive definition of poverty worldwide: likely $1–3 trillion per year.

For permanent eradication (structural, global, including rich countries): tens of trillions over a generation, plus major changes in governance and economic systems.

The lower-end numbers are often cited to show that ending extreme poverty is technically affordable — but the political and institutional will is the real limiting factor.
