How Much Does It Cost To House a Prison Inmate?

The United States has the highest incarceration rate in the world. As of 2020, there were around 1.8 million people in state and federal prisons and local jails across the country. Housing all of these inmates comes at a huge cost to taxpayers. This article will explore the factors that contribute to the high cost of housing inmates and provide estimates on how much states spend per inmate.

Key Stats on Incarceration Rates and Costs

  • The US incarceration rate is 655 per 100,000 residents, over 2.5 times higher than most other developed nations.
  • Federal prisons spend an average of $36,299 per inmate per year.
  • State prisons spend an average of $33,274 per inmate per year.
  • Some states like New York spend over $60,000 per inmate annually.
  • Estimates suggest federal and state prisons spend over $80 billion per year combined on incarceration.

With so many people behind bars, the costs add up quickly. Many factors account for these high per inmate costs, which we’ll explore next.

Why Is Housing Inmates So Expensive?

There are several key reasons why the cost per inmate is so high in the US prison system:

1. Staffing Costs

Correctional facilities require large numbers of staff including guards, counselors, healthcare professionals, administrators and more. Salaries and benefits for staff account for around 2/3 of per inmate costs. The inmate-to-staff ratios are much higher than in other countries.

2. Healthcare Costs

Inmates are entitled to healthcare under the law. With many inmates having chronic medical or mental health conditions, their treatment is expensive. Healthcare accounts for around 20% of per inmate costs.

3. Security Measures

Implementing security features like perimeter fencing, surveillance systems, cell locks and more imposes significant costs for construction and maintenance. Constant supervision is required.

4. Programming and Rehabilitation

Educational programs, job training, counseling/therapy and other rehabilitation efforts aim to reduce recidivism rates. But implementing quality programming comes at a price.

5. Facility Operations and Maintenance

General facility operations like food services, utilities, maintenance, inmate supplies and other basics also contribute to the high costs, even if minimized through cost-saving measures.

6. Legal Costs

Appeals, lawsuits and legal filings by inmates can drive up per inmate costs over time. States must budget for legal expenses.

With all of these costs combined, it’s clear why housing inmates in the US prison system comes at such a high price. The total budgets are enormous for federal and state correctional systems.

State Variations in Inmate Costs

While averages give a general idea of per inmate costs, there is significant variation between states based on factors like:

  • Staffing levels: States with higher staff-to-inmate ratios spend more per inmate.
  • Healthcare costs: The health profile of the inmate population impacts healthcare spending.
  • Programming availability: Rehabilitation and educational programming levels differ between states.
  • Facility size and density: Economies of scale can lower per inmate costs for larger facilities.
  • Private vs. public facilities: Some research suggests private prisons have lower per inmate costs.
  • Wages and unionization: Guard salary and benefit levels impact staffing costs.
  • State budget priorities: Correctional spending may be higher or lower priority for state legislatures.

To illustrate the state variations, here are some examples of different per inmate spending levels:

As shown, per inmate costs in the high-spending states can be nearly 3 times higher than the low-spending states. The factors listed above contribute to these major differences between states’ correctional system costs.

Initiatives to Lower Per Inmate Costs

With state correctional costs often exceeding 10% of total state budgets, there are efforts underway in many states to lower the per inmate costs without sacrificing public safety. Some initiatives include:

  • Staffing optimizations: Restructuring staffing plans and inmate-to-staff ratios while maintaining safety.
  • Healthcare partnerships: Partnering with university health systems or private providers for inmate healthcare.
  • Medication reduction: Reducing prescription medication costs through integrated treatment plans.
  • Sentence reforms: Adjusting sentencing guidelines for non-violent offenders and enhancing probation/diversion programs to lower inmate populations.
  • Education partnerships: Partnering with community colleges and technical schools for education programming at lower costs.
  • Facility modernization: Upgrading outdated prison facilities to be more efficient and cost-effective.
  • Privatization: Contracting private prison operators who can provide lower per inmate costs than public facilities.

Progress has been made to lower costs through these and other initiatives in a number of states. But more work is still needed to balance cost containment with humane treatment of inmates and successful rehabilitation efforts. The costs remain high relative to other nations.

Case Studies: Per Inmate Costs for Notorious Criminals

To illustrate the magnitude of prison system costs, let’s examine some real-world examples of spending on notorious criminals:

Charles Manson

  • Convicted of first-degree murder and conspiracy to commit murder among other crimes.
  • Sentenced to death, later commuted to life in prison after CA abolished death penalty.
  • Spent over 40 years incarcerated before dying in 2017 at age 83.
  • Estimated cost for housing Manson in CA prisons was over $2 million total.

Bernie Madoff

  • Convicted in 2009 of securities fraud, investment advisor fraud, wire fraud, mail fraud, perjury, making false filings.
  • Sentenced to 150 years in prison.
  • Housed in federal prison medical center in NC.
  • Estimated cost of incarceration was over $50,000 per year.
  • Died in prison in 2021 at age 82.

Joaquín “El Chapo” Guzmán

  • Convicted in 2019 on 10 charges related to running the Sinaloa drug cartel.
  • Sentenced to life in prison plus 30 years.
  • Housed in a supermax federal prison in Colorado.
  • Will likely cost over $2 million to house for life due to maximum security measures. Still alive at age 65.

As these examples illustrate, the total costs for housing infamous criminals for life can easily exceed $1 million per inmate. And these costs are borne by taxpayers. For inmates with chronic health conditions, the costs can be even higher over decades of incarceration.

Frequently Asked Questions

How much does it cost to house an inmate for a year?

On average, it costs around $36,000 per year to house an inmate in the federal prison system and $33,000 in the state prison systems. However, costs vary significantly by state, ranging from around $60,000 to $80,000 in high-cost states like New York and California down to around $25,000 to $30,000 in low-cost states like Louisiana and Alabama.

What are the main factors that influence the cost per inmate?

Staffing costs including wages, healthcare expenses, security measures, facility maintenance/operations, rehabilitation programming, and legal costs are the main factors that determine per inmate costs. Personnel costs alone account for around 2/3 of total per inmate spending.

Why does the US have such a high incarceration rate compared to other countries?

High incarceration rates in the US are attributed to lengthy prison sentences, mandatory minimum sentences for drug offenses, three-strikes laws, and other sentencing policies that lead to more imprisonment. The availability of prison beds and use of imprisonment over alternative sanctions also contribute to high incarceration.

Are private prisons lower cost than public prisons?

Research shows private prisons often have lower per-inmate housing costs than public facilities. Private prisons reduce costs by keeping staffing levels and salaries lower. However, some researchers argue this comes at the expense of inmate programs and healthcare quality. The cost savings of private prisons are still debated.

Could reducing inmate populations lower the overall cost burden?

Yes, since inmate housing accounts for the bulk of all costs, measures that reduce inmate populations could substantially lower overall costs. Policy reforms to relax sentencing rules, increase good behavior incentives, expand parole/probation and divert more people away from prison could all potentially reduce inmate populations and generate major cost savings. However, public safety risks from early release would need to be carefully managed.


With over 1.8 million people incarcerated, the United States spends about $80 billion annually on its prison system. High staffing levels, healthcare expenses, security, programming, facilities, and other costs contribute to an average per inmate price tag of around $34,000. State-level costs vary from $25,000 to $60,000-plus based on differing staff ratios, healthcare needs, private prisons, and state priorities.

While incarceration provides punishment and public safety benefits, the substantial taxpayer costs have spurred reforms aimed at reducing inmate populations through alternative sentencing and supervised release programs. With careful implementation, these reforms can potentially lower overall costs without compromising the justice system. But major reductions in per inmate costs are unlikely given all the fixed expenses needed to run secure, humane prison facilities and prepare inmates for life after release. Going forward, policymakers will continue seeking cost-effective ways to uphold public safety while avoiding excessive imprisonment.
