Estimates for ending homelessness in the US vary, with a commonly cited figure of $20 billion annually from the Department of Housing and Urban Development (HUD), though more recent analyses suggest higher or more targeted costs like $9.6 billion extra for Housing First programs to shelter all in 2022.

Key Estimates

• HUD's figure covers providing housing and support for the roughly 650,000 homeless individuals, compared to ongoing crisis costs of $35,578 per chronic homeless person yearly.

• A 2025 National Alliance to End Homelessness study estimates $8.2 billion more for rapid re-housing or supportive housing for sheltered adults, totaling at least $9.6 billion additional on top of $5.45 billion current spending.

• Broader voucher expansion for eligible low-income households could exceed $59 billion yearly, factoring in new affordable housing supply.

Challenges and Context

These costs assume models like permanent supportive housing at $12,800 per person annually, which could save money long-term by reducing emergency services. However, no consensus exists due to factors like mental health needs, housing shortages, and varying definitions of "ending" homelessness. Actual implementation would require sustained funding beyond one-time amounts.
