The United States spends over $81 billion yearly on mass incarceration, according to the Bureau of Justice Statistics (BJS). In 2017, the nonprofit Prison Policy Initiative estimated that the prisons’ total cost to federal and state governments and affected families is approximately $182 billion. 

Meanwhile, over 2 million Americans are incarcerated, according to the Public Broadcasting Service (PBS).

Please keep reading to discover the average costs of state prisoners, the average cost to house prisoners, how experts calculate average prison costs and factors like mass incarceration driving U.S. prison costs.     

How Much State Governments Spend on Every Prisoner per Year

State budgets fluctuate each fiscal year. However, annual prison costs consistently account for a significant part of the yearly budgets. 

These various costs are dependent on the number of inmates within each state. For example, Arizona has one of the nation’s highest incarceration rates. 

Meanwhile, states like Colorado and Michigan are within the mid-range of state rankings, while states like Hawaii have the lowest-ranking incarceration rates.    

Some states spend tens of millions of dollars while others spend several billions of dollars on every prisoner yearly.

For example, California’s 2021-2022 budget provided nearly $14 billion for corrections and rehabilitation. Rehabilitation expenses include rehabilitation programs for drug and alcohol abuse.  

Several groups track government spending to comprehend yearly incarceration costs. Such groups compile data regarding various elements, including facility costs, housing, and food. This process provides a clearer snapshot of states’ per-prisoner spending. 

The Vera Institute of Justice’s 2015 data shows the average yearly per-inmate cost of incarceration in state prison systems ranges from around $14,000 to $70,000 per year, depending on the state. 

However, the figures surge when statisticians apply the annual prison costs to average prison population rates. For example, in 2015, Alabama’s Department of Corrections had the lowest per-prisoner cost yet a prison population of over 31,500.  

Other states like New York and California frequently have high per-prisoner costs. In 2015, the average prison budget among all states was approximately $500 million. 

The Average Cost to House Prison Inmates

The average costs to house federal and state prisoners vary based on various factors, including the type of prison, location, and particular prison.

For example, California’s per-prisoner expense to taxpayers is approximately $106,000, according to the California government. 

Meanwhile, Alabama spent less than $15,000 per prisoner in 2015. 

Various expenses determine the per-prisoner cost, including the following:

  • Facility operating costs
  • Administration 
  • Law enforcement security 
  • Food and canteen
  • Clothing
  • Education
  • Pharmaceuticals 

Such costs vary from state to state. 

In addition, the type of national prison housing federal inmates affects the per-prison costs. Examples of federal prisons based on the level of security provided include minimum, low, medium, and high. 

Prisons with the nation’s maximum security are known as “supermax” prisons. 

The Bureau of Prisons (BOP) spends approximately $34,705 per prisoner per year. The BOP is a U.S. law enforcement agency under the U.S. Department of Justice (USDOJ). 

What Elements Affect Annual Prison Costs Calculations

When states report their annual prison costs, they often cite the average per-prisoner cost. Not all state prisoners cost the same amount to house. However, the overall average provides a clear picture of states’ average annual costs. 

The fundamental equation appears like this: 

total state spending on prisons ÷ average daily prison population = average per-prisoner cost 

Some prisoners cost the state more than others. For instance, particular prisoners may require more medical or mental health services. In other cases, a supermax prison houses the prisoners, so every prisoner is in a single cell. 

Hence, prisons also calculate the average cost of incarceration for prison facilities. For instance, supermax and death row prisoners cost the state more than the general inmate population.

Comprehending which elements comprise the annual prison costs can be complex. 

For example, most Americans are familiar with the various expenses to run a household. They include rent or mortgage and electric, water, and internet bills.  

However, prisons may have various “hidden” expenditures that many people typically would not consider. 

The U.S. BOP uses about 71% of its yearly funding on salaries and benefits of prison staffing. Meanwhile, it spends 9% on food and utilities. Other expenses include rehabilitation programs, such as substance abuse programs and education.

How Mass Incarceration and Mandatory Sentencing Strains Yearly Prison Budgets

Several factors impact state prison budgets, although a key element involves the number of people incarcerated. Federal, state, and local prisons (including community corrections) house approximately 2.3 million imprisoned individuals. Factors that affect this figure include:

Politicians have proposed legislation to reduce prison populations at mass-incarceration centers. 

The First Step Act (2018) allows incarcerated individuals to earn “good time” and leave prison through early release before the conclusion of their sentence.

Good time is an early-release process under determinate (limit-defined) sentencing regimes. The prison grants an automatic sentence reduction for each day prison authorities do not write them up for prison rule violations.

The legislation also reduced mandatory minimums for particular drug-related offenses and eliminated “stacking” sentences in specific instances.  

Stacking sentences allows the prisoner to serve concurrent sentences. The prison releases the inmate after they complete the longest term.

The policy applied the Fair Sentencing Act (2010) and enacted the Second Chance Reauthorization Act (2018). 

These measures have helped decrease prison populations. However, the First Step Act is not a permanent solution. 

The Mandatory Minimum Reform Act (MMRA) (2020) may help lower mandatory minimum sentences more significantly than the First Step Act. 

The Federal prison population has skyrocketed in the past three decades. In addition, yearly prison costs have ballooned since 1980. 

These rates include high recidivism rates. According to, over half of U.S. prisoners the judicial system grants reentry into society every year are incarcerated again within three years. 

U.S. Prison Spending: Employment Is the Primary Driver 

Some complications are involved in conducting state-by-state comparisons of per-inmate costs for these reasons:  

  • Per-prisoner costs tally spending yet do not measure spending’s effectiveness.
  • Increasing the number of prisoners in a prison can reduce the per-inmate costs.
  • Costs vary due to state-by-state age differences. 

The “lion’s share” of state prison expenditures includes personnel costs (salaries, benefits, and overtime). Such costs comprise about two-thirds of total prison spending in 2015. 

Various factors of personnel costs affect total expenditures. Common factors include states such as California and Connecticut, whose corrections employees have higher average salaries. Other U.S. states, such as New York and Massachusetts, have a higher officer-to-inmate ratio. 

Meanwhile, national prison spending is lower for elements like prison health care, which comprises health care providers, hospital care, and pharmaceuticals. One factor is the amount of health care service that the corrections department contracts out. 

States with more health care services that state employees provide spend less on private health services. However, personnel costs still comprise the bulk of prison budgets.

Meanwhile, recidivism comprises up to 10% of yearly prison costs. Recidivism is an individual’s relapse into criminal behavior. 

The quantity of correctional officers per inmate and their average salaries principally drive per-inmate costs. 

Another way to compare how much states spend on prisons is the cost per state resident. 

States with high per-inmate costs may not be “high-cost” states if their average incarceration rates are lower.   

What Exactly Is the Prison-Industrial Complex?

The Prison Industrial Complex (PIC) refers to the intersecting interests of government and industry. It attempts to solve political, economic, and social problems through surveillance, policing, and imprisonment. 

Some estimates report federal, state, and local prisons house over 2.3 million individuals. Meanwhile, approximately twice as many individuals are on probation or parole as incarcerated. 

The U.S. represents less than 5% of the world’s population yet comprises over one-fifth of the global prison population. 

Many experts attribute this mass incarceration to various factors in recent U.S. history, including the following: 

Convicted Drug Offenses

This factor resulting from the drug war has contributed the most to mass incarceration in corrections systems. U.S. President Nixon initiated the “war on drugs” in 1971. 

High Incarceration Rates of People of Color 

Nixon’s war on drugs in the 1970s demonstrated a case study of the trend. The criminal justice system has disproportionately incarcerated non-whites at drastically higher rates than whites. 

For example, state prisons incarcerate black men at significantly higher rates than white men on drug charges. 

Such race-based incarceration rates are not limited to drug crimes.   

The American Civil Liberties Union (ACLU) reported that the future incarceration rates of white boys (one in 17) are significantly lower than for black boys (one in three) and Latino boys (one in six).  

The disproportionate incarceration rates are also significantly higher among other groups, including poor people and disabled people.   

Furthermore, the PIC includes an increasing network of privatized immigration detention centers imprisoning undocumented immigrants. Such facilities house nearly three-quarters of undocumented people, according to the New York Times.  

Such companies can maximize shareholder returns by reducing food, medical, and maintenance costs. 

The ACLU also reported that since the 1970s, the incarcerated population has increased by 500% since 1970. 

Some exceptions include the first year following officials discovering the  COVID-19 pandemic. During that period, prison populations dipped from 2.1 million in 2019 to 1.8 million in late 2020.  

However, crime rates have not increased similarly since the 1970s. For instance, the murder rates have significantly decreased in large cities like Los Angeles and Washington D.C. since the 1990s.  

Additionally, some scholars argue that racism and profits have driven the objective to fill new prisons with human bodies.
