How Much Does a Polygraph Cost

When trust is on the line — in a relationship, in business or during an investigation — a polygraph examination becomes one of the most effective tools available. But before booking a session, everyone wants to know one thing: what is the polygraph cost? The price depends on dozens of factors, and understanding them means you avoid overpaying while still getting a quality result. In this article we take a close look at the cost of a polygraph examination in Ukraine, explain what drives the price, compare the classic and online formats, and show why StimulTest offers the best balance of price and quality.

Average polygraph prices in Ukraine in 2026

The polygraph services market in Ukraine took shape back in the 2010s, and prices have changed significantly over the past decade. Today the cost of a polygraph depends on the type of check, the region and the examiner's qualifications. The approximate price ranges look like this:

As you can see, the polygraph price varies significantly depending on the format. Online testing through StimulTest is on average 30–40% cheaper than the classic procedure with sensors, while delivering comparable accuracy of results.

What is included in the cost of a polygraph examination

To understand how much a polygraph costs, it is important to know exactly what you are paying for. A standard polygraph examination service usually includes several stages:

1. Preliminary consultation

Every examination is preceded by a conversation with the client. The examiner clarifies the purpose of the test, the circumstances of the case, and formulates the key questions. At some companies the consultation is free; others include it in the overall price. At TestStimul, the preliminary consultation is always part of the service cost.

2. Developing the questionnaire

This is one of the most important stages, and it directly affects the quality of the result. A professional examiner puts together an individual set of questions: control, relevant and neutral. The accuracy of the diagnosis depends on the quality of the questionnaire. Drafting the questions is a distinct piece of intellectual work that can take anywhere from 30 minutes to several hours for complex corporate cases.

3. Running the testing session

The polygraph examination itself lasts from 1.5 to 3 hours in the classic format. Online testing with StimulTest usually takes 40–90 minutes thanks to an optimized algorithm. The length of the session is one of the factors that shape the final price: the more complex the case, the longer the examination.

4. Processing the results and preparing the report

Once the testing is complete, the examiner analyzes the collected data and compiles a detailed report. The document contains conclusions for each question, a level of confidence and recommendations. This is not a simple "true/false" — it is a well-reasoned analytical document.

10 factors that affect the polygraph price

Understanding what the cost of a polygraph examination depends on will help you choose the best offer. Let's look at the key pricing factors.

1. Complexity of the check and number of questions

A simple check with 5–8 questions costs less than a comprehensive investigation with 15–20 questions. The more topics you need to cover, the more time the examiner spends preparing and running the test. For example, a marital fidelity check with 6 questions is a basic rate, whereas a corporate theft investigation with dozens of details is already a premium level.

2. Urgency

The standard lead time for booking a polygraph is 3–7 business days. If you need an urgent check within 24–48 hours, most examiners add a surcharge of 30–50% on top of the base price. The online format is more flexible in this respect: StimulTest for individuals lets you arrange testing much faster.

3. The examiner's qualifications and experience

A specialist with 15 years of experience and international certifications charges more than a recent course graduate. And this is justified: an experienced examiner formulates questions more precisely, reads reactions better and makes fewer mistakes. But a high price does not always guarantee quality — it is important to check reviews and reputation.

4. Geographic location

In Kyiv, polygraph prices are traditionally higher than in the regions. Examiners in the capital build office rent, transport costs and a higher level of competition into their prices. In regional centers prices are usually 20–30% lower. And with online testing, geography does not matter at all — you take the check from any city in Ukraine.

5. Format: office, on-site or online

A check in the examiner's office carries the standard price. A visit to the client (at home or at the company's office) usually increases the cost by 500–2,000 UAH depending on the distance. The online format through StimulTest is the most budget-friendly option, since there are no costs for premises, equipment or logistics.

6. Number of people being checked

When a group of people is being tested (for example, an entire company department), examiners usually offer a discount. A typical discount is 10–15% for checking 5–10 people and 15–25% for checking more than 10. StimulTest for business offers special corporate rates with even greater savings.

7. Type of questions: screening or a specific investigation

A screening check during hiring is a standardized set of questions (loyalty, bad habits, criminal history). A specific investigation (who stole money from the till, who leaked confidential information) requires an individual approach and costs more.

8. The need for repeat testing

Sometimes the results of the first session are ambiguous — for example, because the person was overly anxious. In that case a repeat check is recommended. Some companies include one repeat test in the price; others charge 50–70% of the base price for it.

9. Additional services

An extended written report, a consultation with a lawyer about using the results, a video recording of the session, the presence of a third party — all of this can affect the final price. StimulTest's standard package already includes a detailed report and a video recording of the session.

10. Confidentiality and case complexity

Cases that require heightened confidentiality (VIP clients, political matters, high-profile investigations) may carry a higher price because of additional security measures and restricted access to the results.

The hidden costs of a classic polygraph that no one mentions

When you see a price of "from 3,000 UAH" for a classic polygraph, that is only the tip of the iceberg. The real cost of a lie detector for the client includes a number of hidden expenses that examiners do not always warn you about.

Transport costs

A trip to the examiner's office is both time and money. If you are coming from the suburbs or another city, add the cost of fuel, public transport or a taxi. For corporate clients checking employees, this also means paying for the working time of a staff member who travels to the test instead of working.

Time spent traveling and waiting

The average trip to an examiner in Kyiv is 40–60 minutes one way. Add the waiting time, the procedure itself (1.5–3 hours) and the trip back. In total, that is 4 to 6 hours. For a business, this means losing half a working day of one employee, which in monetary terms can cost 500–1,500 UAH.

Time off or leave for the employee

If the check takes place during working hours, the employee needs to be given time off. This is an additional burden on the HR department and on the colleagues who cover for them. The online format lets you take the test at a convenient time without leaving your workplace.

Renting a room (for on-site checks)

If a company invites an examiner to its premises but does not have a suitable room (quiet, isolated), it needs to rent one. Renting a meeting room in a business center costs 300 to 800 UAH per hour.

Classic polygraph vs online StimulTest: a cost comparison

To clearly show the difference in costs, let's consider a typical scenario: a corporate check of 5 sales department employees in Kyiv.

As the comparison shows, the cost of a polygraph examination in the online format can be 2–3 times lower once you factor in all the associated expenses. And the quality of the result remains comparable — StimulTest technology provides multi-channel analysis of micro-expressions, voice and behavior.

Cost of a check for business: corporate rates

For companies that regularly check their staff, the polygraph price is a recurring line item. That is why the question of optimizing the budget is especially pressing.

Volume discounts

Most examiners and online services offer discounts on bundled checks. StimulTest for business offers a flexible system of corporate rates:

• 5–10 checks: 10–15% discount
• 11–25 checks: 15–20% discount
• 26+ checks: an individual rate with the maximum discount

Subscription service

Companies with a constant need for checks (security agencies, financial institutions, logistics companies) can sign a long-term contract. A subscription provides a fixed price per check and priority service.

Integration into HR processes

StimulTest offers integration of testing into corporate HR processes, which makes it possible to automate booking, collecting results and generating reports. This reduces administrative costs and simplifies the process for HR managers.

Cost of a check for individuals: typical scenarios

For private clients, the polygraph price also depends on the specific situation. Here are the most common requests and their approximate cost:

Marital fidelity check

The most popular request among private clients. A standard set of 6–10 questions, one session lasting 40–60 minutes in the online format. The cost at StimulTest is from 1,500 UAH. A classic polygraph will run 2,500–4,500 UAH.

Checking a nanny or household staff

A trust check on the person who looks after your child or works in your home. The questions cover honesty, bad habits and criminal history. The cost is similar to the basic personal check.

Family conflicts and disputed situations

A check in the context of dividing property, inheritance disputes or accusations. It may require an expanded questionnaire and a longer session. The cost is from 1,800 UAH in the online format.

Self-check (voluntary testing)

Some people take a polygraph voluntarily to prove their innocence or confirm certain facts. This is the simplest format of check, with the fewest questions and the lowest cost.

Checks for government agencies: pricing specifics

For government agencies, polygraph pricing follows somewhat different principles. Procurement of polygraph services usually goes through tender procedures with a fixed budget. Government clients place higher demands on certification, reporting and confidentiality, which affects the final cost.

StimulTest meets the requirements of government clients and offers special pricing plans for public-sector institutions, taking into account the specifics of procurement.

Why a cheap polygraph is not always worth it

In their search for an answer to the question of how much a lie detector costs, some clients focus exclusively on the lowest price. This can be a serious mistake.

The risks of a check that is too cheap

• An inexperienced examiner. Newcomers to the field often undercut prices, but the quality of their work can be significantly lower.
• A shortened protocol. To keep the price down, some examiners shorten the session and cut the number of questions, which reduces the reliability of the result.
• No detailed report. Instead of a well-reasoned analytical document, you may receive a single page with a "true/false" conclusion and no explanation.
• Outdated equipment. A cheap polygraph may run on equipment that is 10–15 years old, with lower measurement accuracy.
• No confidentiality guarantees. Without proper protection systems, your results can be compromised.

Why StimulTest costs less without sacrificing quality

A natural question: if the price of a polygraph examination at StimulTest is lower, doesn't that mean lower quality? The answer is no, and here is why:

No spending on physical equipment

A classic polygraph requires expensive equipment (from USD 3,000 to 15,000 per set) that has to be maintained and calibrated. StimulTest uses the client's webcam and microphone — equipment costs on the client's side are zero.

No spending on premises

An examiner needs a specially equipped room with good soundproofing. Renting such a room in Kyiv costs from 15,000 to 30,000 UAH a month. These costs are built into the price of every check. The online format requires no office — both you and the examiner work from your own location.

More efficient use of the specialist's time

In the classic format, the examiner spends time preparing the room, attaching sensors and calibrating the equipment. In the online format this time is reduced, which lets the specialist run more sessions in a day — and therefore lower the price of each one.

Scalable technology

The algorithms for analyzing micro-expressions and voice patterns that StimulTest uses work automatically. This lowers the cost of processing each test without any loss of analytical quality.

How to choose an examiner at a fair price: a checklist

To avoid overpaying and avoid getting a low-quality service, use this checklist:

1. Ask for the full turnkey price. Ask whether the consultation, question development and report are included. Are there any extra charges?
2. Verify qualifications. A certificate, membership in professional associations, at least 3 years of experience.
3. Ask about the methodology. Which type of test is used (CQT, GKT, multi-channel analysis)? How many analysis channels?
4. Find out about the report. What exactly do you get for your money? What does a typical report look like?
5. Compare 3–4 offers. Don't stop at the first option — compare prices, terms and reviews.
6. Consider the online option. If your situation does not require mandatory physical contact, an online check will save you time and money.

Regional differences in polygraph prices in Ukraine

The cost of an examiner's services varies by city and region. Here are the approximate ranges for the main cities:

As the table shows, the price of an online polygraph with StimulTest is the same across all of Ukraine — because geography does not affect the cost of a remote service. This is especially advantageous for residents of large cities, where a classic polygraph is the most expensive.

What affects the price most: the final ranking of factors

Frequently asked questions about the polygraph cost

Can you take a polygraph for free?

There is no such thing as a free polygraph examination — it is a professional service that requires a specialist's qualifications and time. However, some companies, StimulTest in particular, offer a free preliminary consultation during which you can clarify all the details and get an accurate cost estimate.

Why do prices differ so much between examiners?

The difference in prices comes from varying levels of qualification, the format, equipment quality, the scope of services included in the price, and geography. More expensive does not always mean better, and cheaper does not always mean worse. The main thing is to understand what you are paying for.

Are there discounts for pensioners, military personnel or students?

Some examiners and services offer social discounts. Ask about this when you get in touch. StimulTest considers each request individually.

Is money refunded if the result is ambiguous?

An ambiguous result is not an error but an objective situation that can arise. Money is usually not refunded, but a repeat check is offered at a reduced price. StimulTest has a transparent policy for such cases.

Conclusion: what a polygraph examination really costs

The answer to the question of how much a polygraph examination costs depends on many factors: the format, the complexity, the urgency, the region and the specialist's qualifications. A classic polygraph in 2026 runs from 2,500 to 10,000+ UAH per session — and, once you account for hidden costs, even more.

Online testing with StimulTest offers a modern alternative with prices from 1,500 UAH, which is 30–40% cheaper than the classic format. And you get the full package of services: a consultation, questionnaire development, the session itself and a detailed report — with no hidden surcharges, no transport costs and no lost working time.
