Criminal justice professionals work to keep the public safe, which can make it a highly rewarding career. While working in the field can be emotionally fulfilling, criminal investigator salary information also shows that it can be a lucrative path for those interested in law enforcement.

Criminal investigators can focus on many different specialties, but they first need a foundation in understanding criminal justice and the role of law enforcement. A degree program such as App State Online’s Bachelor of Science in Criminal Justice (BSCJ) can help students develop that foundation. From there, they can start their work in the field and gain the experience they need to reach their desired role.

What Is a Criminal Investigator?

A criminal investigator works in law enforcement, often on a police force or for a government agency. These criminal justice professionals, also known as detectives, focus on solving crimes and catching criminals. Criminal investigators don’t typically perform arrests themselves, though they can make them. However, in many cases, their analysis, findings and reports on a particular case are what result in an arrest later.

Criminal investigators typically spend most of their time in the field, working on crime scenes, sourcing evidence, and interviewing witnesses and suspects. Their job is often physically demanding. They may also work in lab settings or in offices, particularly when communicating with others working a particular case, such as forensic science technicians analyzing physical evidence.

Criminal Investigator Job Description

A criminal investigator’s role and responsibilities may include the following:

Analyzing crime scenes and collecting evidence
Interviewing witnesses and potential suspects
Collecting and examining written reports
Writing and communicating detailed case reports
Preparing evidence for trials and testifying about the findings in court

Criminal Investigator Specializations

Criminal investigators often specialize in specific fields. Each specialization focuses on a particular aspect of crime, which can require unique duties in addition to the role’s core responsibilities.

Different specializations include:

Cybercrime: Crimes relating to computers, computer systems and computer networks
Homicide: Criminal activity pertaining to murder
Fraud: Crimes relating to private or government-related fraudulent schemes
Missing persons: Investigations relating to searching for people reported as missing
Narcotics: Criminal activity pertaining to illegal drugs

Criminal Investigator Salary

Criminal investigators play a crucial role in law enforcement, and the median criminal investigator salary reflects their importance.

According to the U.S. Bureau of Labor Statistics (BLS), the median annual salary for detectives and criminal investigators was $93,580 as of May 2024. The bureau reports that criminal investigators are among the highest paid in the law enforcement field. In comparison, the median annual salary for police officers was $76,290.

Many law enforcement agencies offer benefits, including the option for early retirement. At the federal level, for instance, criminal investigators may be eligible for retirement after 25 years of service or at age 50 with at least 20 years of service. Mandatory retirement ages also apply to criminal investigators and can vary at the federal, state and local levels.

Criminal Investigator Salary by Type

Salaries can also depend on specialization. Median annual salaries include:

Cybercrime investigator: Approximately $70,100 as of March 2026 (ZipRecruiter)

Other factors that can affect criminal investigator salaries include education, experience and location.

Criminal Investigator Job Outlook

The BLS projects that the number of positions available for police and detectives will grow by 3% between 2024 and 2034. This projection is on par with the average for all occupations.

How to Become a Criminal Investigator

Criminal investigators may train for specific specialties, but all criminal investigators need to meet the general education, experience and skill requirements.

Education

Working as a criminal investigator requires at least a high school diploma, but in most cases, particularly to specialize in a specific field or work for the federal government, a bachelor’s degree in criminal justice or a related major is required. Students planning to work on a police force will need to pass a law enforcement entrance exam and graduate from a police academy.

Professional Experience

In addition to obtaining the proper education and passing a background check and drug tests, aspiring criminal investigators typically need at least two years of experience in investigative or law enforcement work. Future criminal justice professionals may also consider obtaining certain certifications to help them stand out from their competition, such as the Certified Legal Investigator (CLI) designation from the National Association of Legal Investigators (NALI).

Necessary Skills

The skills required for a career as a criminal investigator include the following:

Attention to detail: Criminal investigators must be able to catch what others miss while collecting and reviewing evidence.
Analysis: Criminal investigators must be able to analyze evidence, crime scenes and testimonies and use critical thinking skills to solve sometimes complex cases.
Adaptability: Criminal investigators must be able to adapt to the situation and maintain their composure, as they see a variety of difficult circumstances that may be upsetting.
Confidentiality: Criminal investigators must be able to keep information confidential to avoid compromising cases.
Physical Strength: Criminal investigators may need physical strength and stamina to pursue and apprehend suspects.
Communication: Criminal investigators must have strong communication skills to relay their findings to different parties, including forensic scientists, district attorneys and other officers working on a case.
Surveillance: Criminal investigators must be able to blend into the background to monitor suspects during cases.

How Education Affects Your Salary as a Criminal Investigator

As with other professional career paths, education is correlated with a criminal investigator salary. Some organizations pay higher salaries to those with a bachelor’s degree than to those entering the field with just a high school diploma or an associate degree.

Part of this is due to increased job opportunities, as most criminal investigator positions require a bachelor’s degree in criminal justice or a related field. For particular specializations, such as cybercrime, hiring agencies may prefer candidates with a master’s degree.

A degree can also make it easier for investigators to advance to senior positions. These roles offer higher salaries due to their expanded responsibilities.

In addition to earning an undergraduate degree, investigators can benefit from studying a second language. Some departments offer salary premiums for bilingual employees.

Preparing for a Career as a Criminal Investigator

Criminal investigators play an integral role in keeping the public safe. Their investigations drive the capture of criminals and help people find justice. To become a criminal investigator and earn a criminal investigator’s salary, students need both experience in law enforcement and the right educational foundation.

The BSCJ program from App State Online prepares students for roles as criminal investigators by teaching the fundamental concepts of criminal justice, as well as helping them hone the skills needed to thrive, such as problem-solving and communication skills.
