Hiring a Private Investigator: How Much Does It Cost?

If you’re considering hiring a private investigator (PI), one of the first questions that likely comes to mind is, "How much does it cost?" While the cost of hiring a PI can vary depending on the scope and complexity of the investigation, most professional private investigators charge anywhere between $100 and $300 per hour. Let's break down some of the factors that affect the cost and what you can expect when hiring a PI (also called a Private Detective).

Factors That Influence the Cost of Hiring a PI

Several factors can affect the overall cost of hiring a private investigator. Understanding these factors can help you estimate the potential cost and budget accordingly.

1. Type of Investigation

Different types of investigations require varying levels of expertise and time commitment. For example:

  • Background checks or simple investigations may require less time and resources, keeping costs on the lower end of the scale.
  • Surveillance, fraud investigations, or missing person cases often require more time and specialized tools, which can increase the hourly rate.

2. Location

The geographic location of the investigation can also affect the cost. For example, investigations in large cities or high-cost-of-living areas may be more expensive due to higher operational costs for the investigator. Additionally, if the investigation requires the PI to travel, you may be responsible for covering travel expenses, such as mileage, accommodations, or per diems.

3. Complexity of the Case

Simple background checks are straightforward, but cases involving financial fraud, cybercrime, or digital forensics demand advanced skills, tools, and additional time. These cases typically fall at the higher end of the hourly range.

4. Time Commitment

Investigations can range from a few hours to several weeks or even months. The longer a PI is actively working a case, the more the final cost will be. Always request an estimated timeframe up front.

5. Tools and Resources

Investigators frequently utilize advanced tools, proprietary databases, and technology to support their work. If your case requires the use of specialized tools, such as dark web monitoring, forensic imaging tools, or proprietary software, this may increase the cost of the investigation.

What Does the Fee Include?

When you hire a PI, their hourly fee typically includes:

  • Initial consultation: Discussing the details of your case, understanding your objectives, and creating a plan of action.
  • Research and analysis: This includes gathering information from databases, records, and open-source intelligence (OSINT) platforms.
  • Surveillance and fieldwork: If required, the PI will conduct physical surveillance, gather photographic or video evidence, and document their findings.
  • Final report: At the conclusion of the investigation, you will receive a detailed written report outlining the findings.

Additional Costs

In addition to the hourly rate, there may be some additional costs depending on the specifics of the investigation:

  • Mileage fees: If the PI needs to travel for your case, they may charge for mileage or transportation.
  • Database fees: Accessing specialized databases may come with additional charges.
  • Court appearances: If the investigator is required to testify in court, they may charge an additional fee for their time.

Is Hiring a PI Worth It?

Hiring a private investigator may seem like a significant investment, but it can provide invaluable information and peace of mind. Whether you’re looking for answers about a personal matter, conducting due diligence on a potential business partner, or gathering evidence for legal purposes, a professional PI can help you uncover the truth discreetly and thoroughly.

Final Thoughts

Hiring a Private Detective typically costs between $100 and $300 per hour, with the final cost depending on factors like the type and complexity of the case, location, and time commitment. It’s essential to have a clear conversation with your PI about fees and expectations upfront so you know what to expect.

Takeaway: The restaurant owner adopted these measures, which strengthened both day-to-day operations and overall security posture . The improvements reduced the risk of negative incidents, safeguarded the establishment’s reputation, and ensured compliance with relevant regulations. By addressing weaknesses before they escalated, the business not only protected its assets but also created a safer environment for employees and patrons alike.

Process: I performed a comprehensive physical security assessment tailored to corporate operations. This included a review of access control systems, visitor management procedures, surveillance coverage, and emergency protocols . I also evaluated employee awareness of security practices and compliance with company policies. Key weaknesses identified included: Gaps in surveillance coverage across parking and entry points Inconsistent enforcement of visitor sign-in procedures Outdated access control measures and lack of employee refresher training I recommended targeted solutions such as upgraded surveillance and access systems, improved visitor management protocols, and the rollout of updated employee training on workplace security.

Background: A family law attorney contacted me after their client’s ex-spouse stopped making court-ordered financial payments. The attorney believed the subject was hiding income and assets, but had limited information to work with. The client needed to locate the individual’s current residence and financial holdings to pursue recovery. Process: I conducted a detailed investigation using a combination of public records searches, social media analysis, and property research . Through footprinting and cross-referencing, I discovered that the subject had shifted assets into a business under an associate’s name. I also identified a previously unknown out-of-state property by comparing real estate filings with geo-tagged social media photos. This information was further supported by vehicle registration data and satellite imagery, which confirmed the subject’s new residence. Takeaway: The attorney used my findings to petition the court for updated financial disclosures and asset freezes. The evidence of hidden property and income streams strengthened their case, ensuring the client could move forward with legal remedies. My investigation not only located the subject but also uncovered concealed assets critical to the litigation strategy.

Background Checks – Protecting Children in Custody Cases Background: A client contacted me with concerns about her children’s safety during visitation with her ex-spouse. She suspected that his new partner might have a criminal background and wanted to ensure her children would not be exposed to risky or illegal behavior while in their father’s care. Process: To address these concerns, I conducted a thorough background investigation and digital footprinting on the new partner and her close associates. This included searches of criminal court records, public filings, deep web sources, and social media activity .

Takeaway: The investigation revealed that the new partner did, in fact, have a criminal record, and one of her immediate family members also had an extensive criminal history. Armed with this information, my client and her attorney successfully petitioned to update the custody agreement, ensuring the children would not be exposed to the new partner during visitation. This case highlights how professional background checks go beyond a simple online search —they provide actionable intelligence that can be used to protect families, strengthen legal cases, and support important personal decisions.

This information allowed my client to avoid entering into a potentially damaging business relationship. By investing in a thorough background investigation, the client protected both his finances and his company’s reputation.

The client needed a reliable investigation to identify and, if possible, locate potential heirs. Process: I performed an in-depth genealogical and investigative search using a combination of probate filings, property records, obituaries, public databases, and social media analysis . I also cross-referenced information through court archives and specialized investigative tools to verify relationships.
