Private Investigator Salary: What PIs Earn and What Drives the Difference

Written by David M. Harlan, Licensed Private Investigator, Last Updated: May 13, 2026

According to the Bureau of Labor Statistics, private investigators earned a median annual salary of $52,370 as of May 2024, with a mean of $61,680. The top 10% earned $98,770 or more. How much you actually make depends heavily on where you work, who you work for, and how you charge for your services, since a large share of PIs bill hourly or by the case rather than drawing a steady paycheck.

Hailing from backgrounds in law enforcement, the military, private security, and loss prevention, often with degrees in criminal justice, public safety, and even psychology, today’s private investigators are redefining outmoded depictions that were never very accurate to begin with.

Common Pay Structure and Compensation Models for PIs

This is a field where you’re not always dealing with a conventional pay structure like you might find in other professions. A significant portion of PIs work independently, running their agencies as sole proprietorships and charging clients directly. Others work as employees of PI firms, financial institutions, insurance companies, or retailers, drawing a regular paycheck like any salaried worker.

According to BLS data, about 10.8% of private investigators are self-employed, while the remaining 89.2% work as wage and salary employees. That split matters when interpreting any salary figure, because BLS surveys capture what employees report, not necessarily what independent operators bill.

For PIs who work independently or on contract, there are two main billing approaches:

• Flat Fee: Flat fees work best for straightforward, predictable assignments (e.g., background checks for an employer) where the scope of work is well-defined. A set price per job keeps billing simple for both parties.
• Hourly Fee: Hourly billing is standard for open-ended cases, including surveillance, missing persons, and fraud investigations. PIs who bill hourly typically charge more for evening and weekend work, and most require a retainer upfront to cover initial hours. Billable time includes active fieldwork, phone calls, research, document preparation, and travel.

Retainers function like a deposit against future hours. The PI draws down from the retainer as work is completed, and if the case runs longer than expected, the client tops it off. This arrangement protects both parties: the client commits to the engagement, and the investigator is compensated for their time before the case closes. If you’re thinking about the independent route, see our guide to establishing an independent PI agency.

2024 Salary Data: What PIs Are Earning Now

The Bureau of Labor Statistics conducts annual surveys of employed private investigators and reports compensation across percentiles. The May 2024 data shows a wide earnings range — from under $35,000 for those just starting to well over $100,000 for experienced investigators in high-demand markets.

National Salary Benchmarks

As of May 2024, the BLS reports the following national figures for private investigators:

The gap between the median ($52,370) and the mean ($61,680) tells a useful story: a smaller group of high earners at the top of the field pulls the average up significantly. For someone entering the profession, the median is the more realistic starting reference point. The 75th and 90th percentile figures represent what’s achievable with experience, specialization, and the right market.

For PIs who charge by the hour, the BLS median of $25.18/hr is a useful baseline. However, many experienced independent investigators charge considerably more, depending on the complexity of the work and local market conditions.

How PI Salaries Compare to Similar Careers

Private investigator salaries fall in the mid-range relative to comparable law enforcement and investigative careers. Police detectives and criminal investigators, roles that often serve as a pipeline into PI work, earn a significantly higher median salary, which reflects their government employer, union protections, and required credentials. At the same time, PIs who build independent practices and develop niche expertise can exceed those benchmarks.

Top-Paying States

State-level earnings vary substantially. These five states reported the highest mean annual wages for private investigators as of May 2024:

Maryland’s jump to the top of the list reflects the concentration of federal government contractors and intelligence-adjacent work in the DC metro corridor, where demand for investigators with security clearance experience drives compensation well above the national norm.

Factors that Can Influence What PIs Earn

Not all PIs charge the same rates, just as not all salaried investigators are paid the same. In this field, experience and formal investigative training carry real weight. Investigators with extensive law enforcement backgrounds and those with degrees in criminal justice consistently command higher pay, both as employees and as independent practitioners.

Experience

Private investigations are largely the domain of retired and former police officers, detectives, criminal investigators, and military personnel. Their deep understanding of the legal process and fieldwork makes PI work a natural fit, and that background translates directly into higher earning potential from day one.

Even without law enforcement experience, investigators can build their resumes working in a support role for a licensed PI, handling public records research for law offices, or working in loss prevention or insurance claims. In many states, investigative experience isn’t just a resume booster. It’s required for licensure. California, for example, requires at least three years of qualifying investigative experience before you can apply for a license.

As a practical income benchmark, the BLS 25th percentile annual wage nationally is approximately $45,580, a reasonable starting point for someone entering a salaried PI position without an extensive background. With five to ten years of experience and a specialty, you’re looking at the 75th percentile range of $75,310 or higher.

Education

An associate’s or bachelor’s degree in criminal justice, police science, or a related field does two things: it often substitutes for some experience in state licensing formulas, and it positions you more competitively for higher-paying employer-side roles. (See our full guide on how to become a private investigator for a step-by-step look at how education and experience work together in the licensing process.) In California, for example, an associate’s degree in criminal justice can substitute for half a year of required experience. In contrast, a bachelor’s degree in police science can substitute for a full year of study.

Private investigators with a law degree occupy a particularly strong position in terms of earning potential. The ability to gather evidence, prepare documentation, and understand admissibility from both investigative and legal angles is highly valued by law firms and corporate clients who pay premium rates for that combination.

Specialization

General PI services pay general PI rates. Investigators who develop deep expertise in specific areas can charge a significant premium, both because fewer investigators offer that expertise and because the clients who need it tend to have deeper pockets. Specializations that command higher fees include:

• Criminal investigation
• Terrorism and intelligence
• Computer forensics
• Marital investigation
• Nursing home abuse investigation
• Insurance investigation
• Pre-employment and employee investigations

Insurance and corporate investigations tend to be among the highest-paying specialties because the clients (insurance carriers, financial institutions, and large employers) have ongoing investigation needs and established vendor relationships. Getting into that pipeline early can be worth more over a career than almost any other move.

Who Employs PIs and How That Affects Pay

Where you work shapes your pay as much as what you do. According to 2024 BLS employment data, general merchandise retailers employ the largest share of private investigators, about 29.5% of the workforce, roughly 12,900 jobs. These are largely loss-prevention and asset-protection roles. The next-largest employers are investigation and security services firms (16%), credit intermediation companies (7.9%), and state and local governments (7.9%). Legal services firms account for another 2.8%.

Government and financial sector roles tend to pay more steadily. Positions in retail and security firms vary widely. Independent operators and those working in specialized investigation and security services firms tend to see the widest income range, from modest starting rates to well above the national mean for experienced investigators with strong client bases.

Professional Association Membership and Certification

Membership and certification in a professional association are reliable ways to set yourself apart, command higher fees, and stay current on legislative changes to the profession. At the national level, ASIS International is the leading name in security and private investigations, with more than 34,000 members worldwide.

PIs who earn the ASIS Professional Certified Investigator (PCI) credential have demonstrated an advanced level of training in evidence collection, case management, and the preparation of reports and testimony. To qualify for the PCI, you need at least five years of investigative experience, including at least two years in case management, plus a passing score on the certification exam. Holding that credential isn’t just a resume line; it signals to clients and employers that you’ve cleared a meaningful professional bar.

Job Outlook and Growth Projections

The BLS projects 6% employment growth for private investigators between 2024 and 2034, in line with the average for all occupations, with approximately 3,900 job openings per year. That figure includes both new positions and openings created by investigators retiring or changing careers.

Total national employment is projected to grow from 43,600 to 46,200 over that period. At the state level, several markets are growing considerably faster. The BLS projects the following states will see the highest PI employment growth between 2022 and 2032:

Washington state’s growth rate stands out: a 34% projected increase is more than five times the national average. Texas and Florida (projected +13.6%) combine large absolute job counts with strong growth rates, making them particularly active hiring markets for investigators entering the field.

Job listings provide a useful real-world supplement to BLS projections. Recent postings illustrate the range of hourly wages employers are advertising across different types of PI roles:

• Private Investigator, Delta Group, Philadelphia, PA: $20–$35/hour
• Pretrial Release Investigator, State of Maryland, Baltimore, MD: $19–$30/hour
• Private Investigator – Surveillance, Insight Service Group, Montpelier, VT: $20–$27/hour
• Special Agent, BNSF Railway, Seattle, WA: $43–$47/hour
• Special Investigations Manager, Health Care Service Corporation, Richardson, TX: $43–$77/hour

Private Investigator Salaries by State

The Bureau of Labor Statistics provides a breakdown of median annual wages and employment by state. The table below shows each state’s median annual wage, top-10% annuPercentile0th percentile, and approximate number of employed PIs as of May 2024. Note that South Dakota and the District of Columbia have suppressed data due to low sample sizes.

* Nevada’s 90th-percentile figure ($187,200) is a published BLS data point but represents a significant outlier relative to the state’s median wage of $47,550. It likely reflects a small number of highly compensated investigators skewing the distribution toward the upper end.

Frequently Asked Questions

Do private investigators make good money?

It depends on experience, location, and how you work. The national median is $52,370 per year, but the top 25% of earners make $75,310 or more, and the top 10% earn $98,770 or more. Independent investigators who develop specialized expertise and a strong client base, particularly in insurance, corporate, or government-adjacent work, can earn well above those benchmarks. Starting salaries for salaried entry-level PI positions are lower, typically in the $40,000–$50,000 range.

How do private investigators get paid?

PIs who work as employees of a firm, retailer, financial institution, or government agency receive a regular salary or hourly wage. Independent investigators typically charge either a flat fee for defined assignments (like a background check) or an hourly rate for open-ended cases, often requiring a retainer upfront. Hourly rates vary widely by market and specialty. The BLS reports a national median of $25.18/hr for the occupation, but experienced independent investigators in high-demand markets often charge significantly more.

What state pays private investigators the most?

Maryland has the highest mean annual wage for private investigators as of May 2024 at $84,950, followed by Oregon ($75,590), New York ($73,290), Washington ($72,710), and Illinois ($71,380). The DC metro area’s concentration of government contracting and intelligence-adjacent work drives Maryland’s figures above the national norm.

Is the job outlook for private investigators good?

The BLS projects 6% employment growth nationally between 2024 and 2034, on par with the average for all occupations. That translates to roughly 3,900 job openings per year. Several states are growing considerably faster. Washington state projects 34% growth and Texas projects 24.6% growth between 2022 and 2032. Insurance fraud investigations, corporate due diligence, and background screening for sensitive positions are driving demand.

Do private investigators need a license?

In most states, yes. Licensing requirements vary significantly. Some states require a background check, a surety bond, and several years of investigative experience. Others add exam requirements on top of that. A few states (like Idaho and Wyoming) have minimal or no licensing requirements. Check the state licensing requirements page for the exact requirements in the state where you plan to work.
