How Much Does a Private Investigator Cost?

May 27, 2025

So you’re thinking about hiring a private investigator, huh? But you’re probably wondering if you’ll need to take out a second mortgage to afford one. Trust me, I’ve been there.

Back when my sister’s car kept disappearing from her driveway at night (turned out her ex had made a copy of her keys—yikes!), we had NO idea what hiring a PI would cost us. It felt like this big mystery that nobody talks about.

Look, I’m not a PI myself, but I’ve done the legwork to figure out how much does a private investigator cost these days. Let me save you the headache and break it down for you.

Key Takeaways About Private Investigator Costs

Most private investigators charge between $50-$200 per hour, with rates varying by location, experience, and specialization
Additional expenses like travel, equipment, and database searches can significantly impact total costs
Complex cases requiring extensive surveillance or specialized skills will cost more than simple investigations
Always get a detailed written agreement specifying all potential charges before proceeding
Budget for 10-30 hours minimum for most standard investigations
Consider the value of legally obtained, admissible evidence when evaluating costs
Thorough preparation and clear communication can help control investigation expenses
The truth, professionally documented, often proves worth the investment regardless of findings

Private Investigator Pricing Structures

OK so most PIs charge using a few different methods. Honestly, it can get confusing fast, but I’ll try to make it simple.

Hourly Rates

This is the most common way PIs bill their clients. They charge by the hour, and wow, the range is pretty crazy. It depends on:

Where you live (big city = bigger bills, usually)
How experienced they are (veterans charge more, obviously)
How complicated your case is
What kind of equipment they need to use
If there’s any risk involved for them

From what I’ve found, hourly rates typically go from around $50 on the super low end to about $200+ for the fancy, ex-FBI types in places like NYC or LA. If you need someone with specialized skills like computer forensics (the folks who can dig through deleted files and all that tech wizardry), expect to pay on the higher end. My buddy in Chicago paid $175 an hour for his corporate case, while my cousin in rural Ohio only paid $65 for a basic background investigation. Location matters—a lot.

Flat Fee Services

Some stuff can just be priced at a flat rate because the PI knows exactly how much work is involved:

Service	Typical Flat Fee Range
Background Check	$100 – $500
Person Locating	$300 – $800
Pre-employment Screening	$150 – $500
Vehicle Registration Search	$50 – $200
Asset Search	$200 – $600

Just a heads up though—always, ALWAYS ask exactly what’s included in these flat rates. When my friend Mark paid for a “comprehensive background check” for $350, he later found out it didn’t include employment verification, which was kinda the whole point. So yeah, get that spelled out beforehand!

Retainer-Based Agreements

For the bigger, longer investigations (think messy divorce cases or corporate stuff), most PIs work on a retainer basis. It’s basically:

You pay a chunk upfront—usually between $1,000 and $5,000
They track their hours and deduct from that amount
They send you updates on how much is left
When you’re getting low, they ask for another deposit

I’ve heard these work pretty well for ongoing situations where you’re not sure how long things will take. My neighbor went through this during her divorce case, and while the initial $3,000 retainer made her gulp, she said it was actually easier than getting surprised by big bills every week.

Average Costs by Investigation Type

Let’s get down to brass tacks. What’s this gonna cost you, really? It depends on what you need the PI for.

Infidelity Investigations

Let’s just put it out there—this is probably the most common reason people hire PIs. And yeah, it’s not cheap. You’re typically looking at anywhere from $1,500 to $5,000 total for these cases. Why so expensive? Well:

They often have to do surveillance at weird hours (when cheating usually happens)
Sometimes they need two investigators if your spouse drives all over town
There’s travel expenses when they follow people
They need cameras and sometimes other tech equipment
They have to document EVERYTHING carefully in case of divorce court

Most cheating investigations take between 10-30 hours of actual work. And sorry to say, but they’re usually done at night and on weekends—prime time for sketchy behavior, which means prime time rates from your PI. My coworker went through this whole mess last year. Her case ended up costing about $2,800 because her husband was meeting someone in the next town over, adding travel expenses. Not fun, but she said knowing the truth was worth every penny.

Missing Persons Investigations

When someone vanishes, it’s terrifying. And sometimes the police can only do so much, especially if the person is an adult who might have left voluntarily. These cases range HUGELY in price—from $1,000 to $10,000 or even more. It really depends on:

How old the case is (fresh trails are easier to follow)
How much info you already have about the person
How far they might have gone
If the PI has to travel to look for them
What databases they need to access (some cost money per search)

Finding someone who disappeared years ago and doesn’t want to be found? That’s gonna cost you way more than finding your 19-year-old who stormed out after an argument last week.

Background Investigations

Before you go into business with someone, hire a nanny, or even get serious in a relationship these days (sad but true), a background check can save you MASSIVE headaches down the road. These range from super basic ($200) to incredibly detailed ($2,000+). They can include:

Criminal history (the basics)
Financial status (bankruptcies, liens, judgments)
Employment history (are they lying about where they worked?)
Education verification (did they really graduate?)
Asset searches (what do they own?)
Social media deep dive (what are they REALLY like?)
Public records search (marriages, divorces, etc.)

Most PIs offer different levels of background checks. My sister got the most basic one done on a potential tenant for $175. I went for the mid-range ($450) before bringing on a business partner. Worth. Every. Penny.

Corporate Investigations

This gets into the big leagues. Businesses hire PIs for things like:

Catching employees stealing (more common than you’d think!)
Protecting intellectual property (someone leaking secrets to competitors)
Checking out companies before merging with them
Making sure workers comp claims are legit (sorry, but people do fake injuries)
Investigating internal fraud (embezzlement and all that fun stuff)

These get EXPENSIVE. Like, $2,000 to $25,000+ depending on what needs to be done. But for companies, it’s usually worth it when they’re facing potential losses in the hundreds of thousands.

Additional Costs and Expenses

Oh, you thought the hourly rate was all you’d pay? Sorry, but nope. There’s usually other stuff that gets tacked on.

Travel Expenses

If your PI needs to go beyond their normal area, expect to pay extra for:

Mileage (they usually charge about 50-75 cents per mile)
Plane tickets and hotels if they have to go far
Meals (yep, you’re buying their lunch)
Tolls and parking

This stuff adds up FAST. My friend’s PI had to drive from Phoenix to Tucson for three days of surveillance, and just the travel expenses alone were over $600. That was on top of the hourly rate!

Equipment and Technology Fees

Sometimes PIs need special equipment for your case, and—shocker—that costs extra:

GPS trackers: $50-$200 per day (and yes, there are legal ways to use these)
Hidden cameras: $100-$300 per day
Fancy surveillance gear: $200-$500 per day
Digital forensics tools: $200-$500 per hour (for recovering deleted texts, emails, etc.)
Database searches: $50-$200 per search

Always, ALWAYS ask upfront what equipment might be needed. Nothing worse than getting blindsided by an extra $500 charge because they had to use some special camera you didn’t know about.

Court Appearances and Expert Testimony

If your PI finds something that ends up going to court, their time gets A LOT more expensive:

Depositions: $500-$1,500 per day (they have to dress nice and everything)
Actual court appearances: $750-$2,000 per day
Getting ready for trial: $150-$250 per hour
Being an “expert witness”: $1,500-$5,000 per day

These fees are higher because your PI has to look professional, be prepared for questioning, and potentially face cross-examination. Trust me, you WANT them to be well-prepared if they’re testifying about evidence they found.

Factors That Influence Private Investigator Costs

Let’s talk about WHY there’s such a huge range in what PIs charge. Several things affect how much does a private investigator cost:

Geographic Location

This is probably the biggest factor. Check out these differences:

Region	Average Hourly Rate
Big Cities (NYC, LA, Chicago)	$125 – $250
Medium-sized Cities	$85 – $150
Small Towns & Rural Areas	$50 – $100
International Work	$150 – $500+ (yikes!)

Why such a difference? Cost of living, mostly. A PI in Manhattan has way higher office rent and expenses than one in a small town in Nebraska. When I was shopping around, the difference between Chicago PIs and those just 45 minutes outside the city was almost $70 per hour!

Experience and Reputation

Just like with lawyers or doctors, experience matters—and costs more:

Newbies (1-3 years): $50-$80 per hour
Mid-career PIs (4-10 years): $85-$150 per hour
Old-timers with serious experience (10+ years): $150-$250+ per hour
Former FBI, CIA, or high-level police: Often the most expensive

I know it’s tempting to go with the cheaper option, but from what I’ve seen, experienced PIs work WAY faster and more efficiently. My coworker hired a rookie and ended up paying more in the long run because the guy took forever to get results. Sometimes cheaper hourly rates actually cost more overall!

Case Complexity

Obviously, the more complicated your situation, the more it’ll cost. Complexity factors include:

How many people they need to watch
How many places they need to monitor
How hard it is to get the evidence you need
Any legal obstacles they’ll face trying to get information
Any risks the investigator might face (some neighborhoods aren’t exactly PI-friendly)
How quickly you need answers

A simple “is my employee really sick or are they at the beach” case is going to be way cheaper than “I need to find out who’s stealing company secrets and selling them to our competitor.”

How to Budget for Private Investigation Services

Look, nobody wants financial surprises, especially when you’re already dealing with whatever situation made you need a PI in the first place. Here’s how to avoid budget shocks:

Initial Consultation

Most decent PIs offer a free or low-cost initial consultation. Use this time to:

Explain your situation (all the details—they need the whole picture)
Ask how they’d approach your case
Get them to estimate costs
Understand their process
Ask ALL your questions (seriously, this is not the time to be shy)

I talked to three different PIs before picking one. The cheapest one actually seemed the least knowledgeable, and the most expensive one seemed to be padding the estimate with stuff I didn’t need. The middle one explained everything clearly and gave me confidence she knew what she was doing. Worth the extra calls!

Get Everything in Writing

I CANNOT stress this enough. Get a detailed contract that spells out:

Their hourly rates (and if they charge different rates for different activities)
A TOTAL estimated cost range (get both low and high end estimates)
When and how they’ll bill you
What counts as an “extra expense” and how they’ll handle those
What happens if you need to cancel
Confidentiality stuff (super important!)
Exactly what they’ll deliver to you (reports, photos, videos, etc.)

My buddy got burned because his PI’s “surveillance” didn’t include actually taking photos—that was an extra service! Everything was technically legal, but what good is surveillance with no proof? Get. It. In. Writing.

Set a Hard Budget Limit

Be upfront about what you can afford:

Tell them your absolute maximum budget
Ask them to notify you when you’re getting close to certain amounts
Be clear about which parts of the investigation matter most to you
Ask if there are cheaper alternatives for parts of the work

A good PI will work with your budget constraints. When I hired one last year, I told them my absolute max was $2,500. They called me when we hit $2,000 to discuss if we should continue or wrap things up with what we had. I appreciated not getting a surprise $3,500 bill!

Typical Price Ranges by Service Type

To help with your budgeting, here’s a breakdown of typical costs for specific investigative services:

Surveillance Services

Surveillance is often the most expensive investigative service due to its labor-intensive nature:

Surveillance Type	Typical Cost Range
Basic Surveillance (1 investigator)	$500 – $1,200 per day
Two-Person Surveillance Team	$900 – $2,000 per day
Technical Surveillance (with specialized equipment)	$1,000 – $2,500 per day
Long-term Surveillance (weekly rates)	$3,500 – $12,000 per week

Most surveillance operations require a minimum of 4-8 hours to be effective, with many investigators requiring a minimum booking.

Skip Tracing and Person Location

Finding someone who doesn’t want to be found requires specialized skills and resources:

Basic person location: $250 – $650
Skip tracing for debtors: $300 – $800
Locating estranged family members: $400 – $1,200
International person searches: $1,500 – $5,000+

Success rates for these services vary based on how thoroughly the subject has covered their tracks and how much information you can provide initially.

Legal Support Investigations

Investigations supporting legal proceedings have their own pricing structure:

Witness interviews: $200 – $600 each
Evidence gathering: $1,000 – $5,000
Accident reconstruction: $2,500 – $10,000
Jury research: $1,500 – $7,500
Asset investigations for litigation: $1,000 – $8,000

These specialized services often deliver substantial value by strengthening legal positions or identifying settlement opportunities.

Cost Comparison: DIY vs. Professional Investigation

Many people initially consider handling investigations themselves to save money. Here’s how the costs and benefits compare:

DIY Investigation Costs

Time investment: 20-100+ personal hours
Learning curve: Substantial
Equipment purchases: $500 – $2,000+
Database access: Limited or expensive
Legal risks: Significant

While DIY investigation has a lower financial cost, it comes with substantial risks including potential legal violations, wasted time, and missed evidence.

Professional Investigation Value

Professional investigators offer several advantages that often justify their costs:

Legal compliance expertise
Admissible evidence collection
Professional documentation
Specialized training and techniques
Access to proprietary databases
Objective third-party perspective
Confidentiality protections
Potential court testimony

When weighing costs, consider both the financial investment and the value of properly executed, legally sound investigation.

Questions to Ask About Costs Before Hiring

Before committing to any investigator, ask these important questions:

“What is your exact fee structure, including all potential charges?”
“How much retainer do you require, and is it refundable?”
“What additional expenses might arise during my case?”
“How will you document time spent and expenses incurred?”
“Can you provide a written estimate for my specific case?”
“What happens if costs exceed the estimate?”
“Are there ways to reduce costs while still achieving my goals?”
“Do you offer payment plans or accept credit cards?”

Reputable investigators will answer these questions clearly and transparently.

Red Flags: When to Question Private Investigator Costs

Be wary of these pricing red flags when hiring a PI:

Suspiciously Low Rates

If an investigator’s rates are dramatically lower than others in your area, question why. They might:

Lack proper licensing or insurance
Have limited experience or training
Use questionable or illegal methods
Provide substandard reports
Engage in bait-and-switch pricing tactics

Quality investigation work requires proper training, equipment, and resources, which are reflected in reasonable pricing.

Lack of Transparency

Be cautious if an investigator:

Refuses to provide a written contract
Is vague about potential costs
Won’t provide itemized billing
Demands large cash payments upfront
Cannot clearly explain their fee structure

Transparency in pricing is a hallmark of professional investigators.

Guarantees of Results

Be suspicious of any investigator who guarantees specific outcomes. Ethical investigators will:

Explain what they can reasonably accomplish
Discuss potential challenges and limitations
Present realistic timeframes and expectations
Avoid promising specific evidence or results

Investigation outcomes depend on many factors beyond the investigator’s control, and guarantees often indicate questionable ethics.

Finding Value in Private Investigation Services

While cost is important, value should be your primary consideration when hiring a PI:

Licensing and Credentials

Verify that any investigator you hire:

Holds current state licensing
Carries professional liability insurance
Has relevant certifications in their specialty
Maintains professional association memberships
Has appropriate background and training

These qualifications often correlate with higher rates but also better results and legal compliance.

Technology and Resources

Investigators with access to better tools often provide superior results:

Proprietary database access
Advanced surveillance equipment
Digital forensics capabilities
Secure evidence management systems
Professional networks and contacts

These resources represent significant investment on the investigator’s part, justifying somewhat higher rates.

Reputation and Reviews

Research potential investigators through:

Client testimonials (where confidentiality allows)
Professional references
Better Business Bureau ratings
Online reviews and reputation
Court testimony history

A strong reputation often commands premium rates but provides peace of mind and better outcomes.

Making the Most of Your Investigation Budget

To maximize the value of your investment in private investigation services:

Prepare Thoroughly

Help your investigator work efficiently by:

Organizing all relevant information before your meeting
Providing complete details of what you already know
Sharing photos, documents, and other evidence
Clarifying exactly what information you need
Being completely honest about the situation

Better preparation can significantly reduce investigative hours and costs.

Focus the Scope

Narrow your investigation to the most critical questions:

Identify your primary objectives
Prioritize which questions need answers first
Consider a phased approach to the investigation
Set clear parameters for the depth of investigation
Be specific about required evidence standards

Focused investigations are typically more cost-effective than open-ended searches.

Communicate Effectively

Maintain appropriate communication with your investigator:

Establish preferred communication methods and frequency
Respond promptly to requests for additional information
Ask for regular progress updates without micromanaging
Discuss any concerns about direction or costs promptly
Be receptive to professional advice about approach

Good communication prevents wasted effort and helps control costs.

Your Investment in Truth and Peace of Mind

When considering how much does a private investigator cost, remember that you’re not just paying for someone’s time—you’re investing in:

Professional expertise and trained observation
Legal and ethical information gathering
Documented, admissible evidence
Objective third-party assessment
Peace of mind through knowing the truth
Resolution of troubling questions
Protection of your personal or business interests

For many clients, the definitive answers provided by professional investigation prove invaluable, regardless of the findings.

What Comes After Hiring a PI

Once you’ve hired a private investigator and understand the costs involved, prepare for:

Regular updates and progress reports
Potential strategic adjustments as the case develops
Documented evidence collection
Comprehensive final reporting
Secure evidence handling and confidentiality
Potential testimony or affidavits if required
Professional recommendations based on findings

The investigator’s work product should justify the investment by providing clear, actionable information that helps you move forward with confidence.
