Polygraph Test Cost and Pricing Guidelines

The long answer: The price of a polygraph test varies based on several factors, like:

• Type of test (relationship, attorney-requested, family, pre-employment, and so on)
• Location and availability
• Issue complexity and time needed
• Number of people being tested
• Single test vs. contract work

That’s why I only provide quotes over the phone, not online.

But while those and some other factors might affect the pricing, my typical lie detector test price ranges between $900 and $1500+, with an average of $1250.
This cost reflects a real polygraph exam conducted with professional-grade equipment in a distraction-free location.

Every case is different, and I’ll walk you through what’s involved and what to expect.

How Much Does an Infidelity Polygraph Test Cost?

While infidelity seems specific enough, the polygraph test cost varies even across different infidelity cases. Often, the number lands close to $1,250, but that depends on what’s actually involved, which is why I go over it with you directly.

Factors That Affect Polygraph Exam Costs For Infidelity

1. Objective of the Test

Infidelity polygraph tests fall under what are called specific-issue exams. That means that I build the entire process around a narrow set of questions tied to one concern, such as:

• Has there been physical cheating during a specific time period?

• Was there ongoing communication of a romantic nature with a person other than your spouse?

• Did a specific act happen after a certain date?

Those details shape how the exam is set up and how long it takes, and that’s what ultimately drives the cost of the polygraph test.

2. Number of Examinees

In most cases, an infidelity exam involves one person being tested. That’s the most common scenario, and it is typically the most straightforward from a pricing standpoint.

With The Polygraph Examiner, the lie detector test price includes:

• A full pre-test interview
• A carefully structured question set
• Multiple chart collections
• Reiterative questions to ensure accuracy

I do not abbreviate anything about this process simply because the issue is “relationship-related.”

The cost of the polygraph exam changes if there is more than one examinee.

Of course, it’s not a matter of simply multiplying the price by the number of examinees, because each case and individual is treated separately for the sake of accuracy. Individual tests, couples’ tests, and retests are all treated differently.

That’s why you should call me for an accurate quote of the polygraph test cost for your case.

3. Distance to the Test Location

The average cost of cheating polygraph tests increases based on the distance I have to travel for the test.

I conduct tests in North Carolina, South Carolina, Georgia, and some parts of Virginia, which sometimes involve long drives.

During these drives, I travel with my own equipment, which is the same equipment as the FBI, Secret Service, and CIA. This is what allows me to achieve the most accurate results possible.

Finally, I have to look for a neutral site within the test location so that I can guarantee your privacy while protecting your information.

All these considerations contribute to the cost of the polygraph test. However, this polygraph test price gets you a result more accurate than the industry average.

Where I Test From and Why I Never Work in Homes

For ethical and accuracy reasons, I don’t offer in-home testing. I test in private, neutral environments like office suites and conference rooms to control distractions and guarantee the integrity of your results.

Photos, children, phones, and unexpected guests can all interfere with results. With me, your polygraph test cost accounts for the setting, equipment, and professionalism required to achieve results with very high accuracy.

What Kind of Tests Do I Offer?

Most exams are specific-issue tests, meaning one question or scenario is being examined. Common cases include:

• Infidelity and relationship testing
• Family lie detector test situations involving trust, accusations, or parenting
• Legal exams that are requested by attorneys
• Business-related investigations
• And more!

I never cut corners. This is why my polygraph test costs are the way they are. I use the most accurate techniques available and follow strict protocols established by the American Polygraph Association.

Payment and Policies

I use PayPal for all payments for several reasons:

• Security: PayPal requires accountability from its vendors, so even though the lie detector test price may seem high, you know you will receive the services you have purchased.
• Flexibility: You’ll have the flexibility to pay with any major credit card, debit card, or e-check.
• Privacy: Your credit information is only seen by PayPal, which guarantees your financial privacy.

Another aspect to consider about my polygraph test costs and policies is that I am highly mobile for client convenience. This helps me to be flexible and highly accessible and requires me to be efficient in fee collection and scheduling. I wouldn’t be able to keep fees reasonable if an examinee doesn’t show up after I’ve traveled hundreds of miles to their location.

Please note that for these reasons, full payment is required when you book your appointment, and payments are not refundable, so please only schedule if you’re certain you can attend.

I want to work with and for you. I always aim to provide the fairest price for my polygraph exam services, backed by decades of experience and education.

You are always welcome to call for a free consultation just to explore the polygraph test cost options. No obligation.

Polygraph Contracts and Group Testing

If you’re representing an agency or business and need multiple tests or ongoing service, I offer contract pricing. This includes:

• Government and law enforcement pre-employment exams
• Testing for convicted sex offenders (state or federal)
• Security companies and armored car firms

Please email your RFP or inquiry about the lie detector test price for contract or group testing services. Include your name and phone number for the fastest response.

Frequently Asked Questions

How much is a lie detector test for cheating?

The number people usually hear is $1,250, but it does not land there by default. Some callers have one clear issue they want addressed. Others are trying to sort through a longer story. How focused the concern is and how far back it goes both affect what the exam looks like.

Until I understand what you’re actually trying to solve, any lie detector test price figure would likely be misleading. That’s why I go over the situation first and explain what the exam would involve before talking about numbers.

What determines the infidelity polygraph test price?

The polygraph test cost is determined by how much preparation and testing time the case requires. A straightforward situation with a clear allegation is different from one where the story has changed multiple times or where several issues are being combined into one exam.

I do not charge based on emotion or urgency. I charge based on what it takes to run a proper exam that produces results you can rely on.

Why does the lie detector test for cheating cost vary from case to case?

No two relationship cases unfold the same way, and that affects the polygraph test cost. Some people come in with one specific question they want answered.

Others are dealing with months or years of uncertainty. The more complicated the background, the more care has to go into the interview and question design. That extra work changes the scope of the exam, and that is why polygraph exam costs can vary widely instead of staying flat.

How does location impact the lie detector test price?

Location matters because I do not test in homes. I use controlled, neutral environments, and I travel to serve clients across multiple states. Travel time, room availability, and scheduling all factor into the final polygraph test cost.

When people search for lie detector test prices for services near them, they are usually trying to compare convenience. I focus on making sure the setting supports accurate results, even if that means the logistics are more involved.

Do infidelity polygraph tests cost more than other exams?

In most cases, an infidelity test is priced similarly to other specific-issue exams. The difference is not the topic itself, but the preparation involved.

Relationship cases often require careful framing of timelines, behaviors, and boundaries so the questions stay clear and fair. When that takes additional time, it can affect the overall polygraph cost for an infidelity test, but there is no surcharge simply because the issue involves cheating.
