The median annual salary for crime scene investigators is $67,440, according to the U.S. Bureau of Labor Statistics (May 2024), which classifies CSIs under the forensic science technician occupational category. Entry-level positions start around $45,560, while senior CSIs and federal forensic specialists earn $95,000 to $110,710 or more.
But that headline figure tells only part of the story. A CSI’s salary depends heavily on one factor most career guides overlook: whether you enter the field as a civilian technician or as a sworn law enforcement officer. Those two paths lead to meaningfully different pay scales, advancement ceilings, and total compensation packages – and understanding the distinction before you choose your career path is one of the most valuable things this guide can do for you.

Civilian CSI vs. Sworn Officer CSI: A Critical Salary Distinction
This is the most important salary factor most CSI career guides fail to address clearly. Crime scene investigation is performed by two distinct types of professionals, and they are paid on entirely different scales:
Civilian forensic science technicians are non-sworn employees hired directly into crime lab or field CSI roles based on their scientific education and technical skills. They do not go through a police academy and do not carry a badge or firearm. The BLS median salary for this category is $67,440.
Sworn officer CSIs are police officers or detectives who have been assigned to or promoted into crime scene investigation roles. They have completed a police academy, hold a law enforcement certification, and earn pay on the police officer or detective scale – which has a national median of $77,270 for officers and $93,580 for detectives and criminal investigators.
At most large metropolitan departments, sworn officer CSIs earn substantially more than their civilian counterparts doing similar work, because their base pay is anchored to the law enforcement pay scale rather than the forensic technician scale. They also have access to law enforcement pension benefits, which are significantly more generous than standard public employee retirement plans.
The tradeoff: the civilian path typically has a lower barrier to entry – a bachelor’s degree in forensic science, biology, or chemistry is usually sufficient – while the sworn path requires completing a police academy and accumulating patrol experience before specializing in CSI work.
For a full breakdown of both pathways, see our Crime Scene Investigator Career Guide.
CSI Salary by Experience Level
Entry-Level CSI (Years 0–3)
New civilian CSIs typically earn between $45,560 and $55,000 in base salary, reflecting the BLS 10th to 25th percentile range for forensic science technicians. Federal agencies and large metropolitan departments generally offer higher starting salaries than smaller local departments. CSIs with bachelor’s degrees in forensic science or chemistry tend to enter at the higher end of this range, while those with criminal justice degrees and less laboratory background may start lower.
Mid-Career CSI (Years 3–8)
With three to eight years of field and laboratory experience, CSIs move into the $55,000 to $75,000 salary range. At this stage, specialization begins to drive compensation – CSIs who develop expertise in digital forensics, DNA analysis, or fingerprint examination earn more than generalists. Many mid-career CSIs also pursue professional certification through the International Association for Identification (IAI), which strengthens both their position within the agency and their competitiveness for higher-paying roles.
Senior CSI (Years 8–15)
Senior CSIs with deep expertise and strong case records earn $75,000 to $95,000, approaching the BLS 75th percentile of $88,710. At this level, CSIs are typically working complex cases independently, serving as expert witnesses in court, and mentoring junior technicians. Federal lab positions — particularly at the FBI Laboratory Division – become accessible to candidates with this level of experience and are among the highest-paying CSI roles available.
Lead CSI / Crime Lab Supervisor
CSIs who move into supervisory or laboratory leadership roles earn $88,710 to $110,710 or above, placing them in the BLS 75th to 90th percentile. At major agencies and state crime labs, lab directors and senior forensic scientists can earn above $120,000. These positions typically require advanced degrees or extensive certifications in addition to years of field experience.
CSI Salary by State
Geographic location significantly affects CSI compensation, with high-cost states and those with large metropolitan crime labs consistently paying the most:
| State | Median Annual Salary (Est.) |
|---|---|
| California | $90,000 – $110,000+ |
| Washington | $80,000 – $98,000 |
| New York | $80,470 – $101,000+ |
| Massachusetts | $75,210 – $105,000 |
| Nevada | $73,700 – $127,000 |
| New Jersey | $72,000 – $95,000 |
| Illinois | $68,000 – $88,000 |
| Texas | $58,000 – $78,000 |
| Florida | $52,000 – $72,000 |
| Mississippi | $40,000 – $55,000 |
Figures based on BLS OEWS May 2024 state data for forensic science technicians. Ranges reflect entry to senior levels. Sworn officer CSIs at these locations earn on the law enforcement pay scale and will typically earn higher figures than those shown.
Salary by Specialization
Within crime scene investigation, specialization is one of the clearest paths to higher earnings. Emerging forensic disciplines – particularly those involving technology – command a premium as departments compete for qualified personnel:
| Specialization | Estimated Salary Range | Notes |
|---|---|---|
| Digital / Cyber Forensics | $80,000 – $120,000+ | Fastest-growing specialty; strong federal demand |
| DNA Analysis | $72,000 – $105,000 | High demand at state and federal crime labs |
| Bloodstain Pattern Analysis | $70,000 – $100,000 | Specialized certification required (IAI) |
| Fingerprint / Latent Print Examiner | $65,000 – $95,000 | Consistent demand; court expert witness role |
| Firearms / Ballistics Examiner | $65,000 – $95,000 | Strong federal law enforcement demand |
| Toxicology | $68,000 – $98,000 | Often lab-based; requires chemistry background |
| General Crime Scene Technician | $45,560 – $75,000 | Entry point for most civilian CSIs |
Factors That Affect CSI Pay
Civilian vs. sworn pathway. As outlined above, this is the single largest salary determinant for most CSIs. Sworn officer CSIs at major departments earn substantially more than civilian technicians performing comparable work.
Agency type. Federal agencies – FBI Laboratory Division, DEA, ATF, Department of Defense forensic labs – pay on the GS pay scale and consistently offer higher salaries than state and local agencies, particularly for mid-career and senior specialists. The FBI Laboratory in Quantico is among the highest-paying forensic science employers in the country.
Education level. A bachelor’s degree in forensic science, biology, or chemistry is the standard entry requirement. Advanced degrees – a master’s in forensic science or a related discipline – qualify candidates for senior laboratory roles and federal positions at higher starting grades, directly increasing starting salary by $8,000 to $15,000.
Professional certification. Certifications from the International Association for Identification – including Certified Crime Scene Investigator (CCSI), Certified Latent Print Examiner (CLPE), and Certified Crime Scene Analyst (CCSA) – are widely recognized and often required for promotion to senior roles. Certified specialists consistently earn more than uncertified peers at the same experience level.
Overtime and on-call pay. Crime scenes don’t follow a schedule. CSIs at field-based agencies frequently earn significant overtime, particularly during major investigations. Shift differentials for evening and overnight work also add meaningfully to total annual earnings at many agencies.
Benefits and Total Compensation
CSI compensation includes a benefits package that varies significantly based on whether the role is civilian or sworn:
Civilian CSI benefits typically include standard public employee provisions: health insurance with employer contribution, a defined-benefit or defined-contribution pension, paid time off, and continuing education support. At local government agencies, the employer typically covers 70 to 85 percent of health insurance premiums.
Sworn officer CSI benefits include the enhanced law enforcement retirement provisions described in our Detective Salary Guide – earlier retirement eligibility, higher pension multipliers, and comprehensive coverage that adds substantial value beyond base salary. The actuarial value of a law enforcement pension over a retirement lifetime routinely exceeds $500,000 to $1,000,000.
Federal CSI positions at agencies like the FBI add the full federal benefits package: Federal Employees Health Benefits (FEHB), Thrift Savings Plan with employer matching, Federal Employees’ Group Life Insurance, and generous paid leave provisions.
Job Outlook
Employment of forensic science technicians is projected to grow 13 percent from 2024 to 2034 – much faster than the average for all occupations, and more than four times the growth rate for patrol officers and detectives. The BLS projects approximately 2,900 openings annually over the decade.
This growth is driven by several converging factors: expanding use of forensic evidence in criminal prosecutions, rapid advances in DNA technology and digital forensics, and the increasing capacity of crime labs at the state and federal level. Departments that previously sent evidence to regional labs are building in-house CSI capacity, creating new civilian positions across the country.
The fastest growth is concentrated in digital forensics and cybercrime investigation – a specialization where qualified candidates are genuinely scarce and compensation reflects that scarcity. CSIs with both field forensic skills and digital evidence expertise are among the most sought-after professionals in the law enforcement labor market.

Frequently Asked Questions
How much do CSIs make starting out?
Entry-level civilian CSIs typically earn between $45,560 and $55,000 annually, based on BLS May 2024 data. Federal agencies and large metropolitan departments generally offer higher starting salaries, while smaller local agencies may start at the lower end of that range. Candidates with forensic science degrees and laboratory experience tend to earn more at entry than those with general criminal justice backgrounds.
Do CSIs make more than police officers?
Generally, no – at least on the civilian pathway. The BLS median for forensic science technicians ($67,440) is below the median for patrol officers ($77,270). However, sworn officer CSIs who hold detective rank earn closer to the detective median of $93,580, which exceeds patrol officer pay. The civilian vs. sworn distinction is the key variable here.
What state pays CSIs the most?
California consistently leads in CSI compensation, with forensic science technicians earning $90,000 to $110,000 or more at the median. Washington, New York, Massachusetts, and Nevada also rank among the highest-paying states. Cost of living significantly offsets these figures – a CSI earning $75,000 in a lower-cost state may have comparable or better purchasing power than one earning $95,000 in California.
How much do federal CSIs make?
Federal forensic specialists at the FBI, DEA, ATF, and Department of Defense labs earn on the GS pay scale. Entry-level federal positions typically start at GS-7 ($49,000 to $55,000) and advance to GS-11 through GS-13 ($67,000 to $108,000) with experience. Senior lab scientists and supervisors at GS-14 and GS-15 earn $113,000 to $142,000 before locality adjustments.
Is becoming a CSI worth it financially?
For candidates drawn to forensic science, the career offers solid middle-class compensation with excellent job security, meaningful work, and one of the strongest growth outlooks in law enforcement. The 13% projected growth rate through 2034 signals sustained demand and consistent hiring. Financially, the highest returns come from the sworn officer pathway or federal agency positions – both of which combine stronger base pay with superior benefits packages.
