How much does a lie detector test cost? Our polygraph pricing is fixed upfront and settled in USDT — online examinations from $205, in-person from $250, with the exact figure depending on the country, the format and the number of people. Below is the full price list by country, plus what shapes the final quote.
In short: a professional lie detector test costs from $205 online and from $250 in person, rising to about $550 in the priciest markets; testing in an additional language adds around $95. Every price is confirmed before the test and paid in USDT, and the first consultation is free.
Prices are quoted in USD and settled in USDT. Local-currency equivalents (£, €, CA$ and others) are shown on each country's own page.
The in-person price depends mainly on the country. Below is the current list for the markets we cover; the online format is $205 everywhere, and an additional test language adds about $95 in any location.

Two identical-sounding cases can be quoted differently, because a polygraph fee is built from several factors. The main ones:

Get your exact price →The first question almost everyone asks is a simple one: how much does a lie detector test cost? The honest answer is that it depends — but on a small, transparent set of factors rather than anything hidden. The two biggest are the format and the country. A remote, online examination is a flat $205 anywhere in the world, while an in-person session ranges from around $250 in more affordable markets to roughly $550 in the priciest, reflecting local costs of a certified examiner and a private venue. Everything is quoted upfront and paid in USDT, and nothing is added to the invoice after the fact.
From there the figure moves with a few practical details. Running the test in a second language — most often English alongside Russian — adds about $95, because it takes extra preparation to word every question so it reads exactly as intended. Testing several people at once brings a group discount, and a full workforce screening is priced bespoke and booked ahead. If you need an examiner to travel to your office or site, that visit is quoted case by case; and a rushed, priority turnaround can be arranged for an agreed premium.
An online polygraph removes the venue and the travel, which is why it sits at a lower, flat rate. It suits many private matters and single-person cases well. An in-person examination costs more because it involves a certified examiner attending a private room with professional, multi-channel equipment — but for group screenings, workplace investigations and anything where the setting matters, it's usually the right choice. The preparation is identical either way: a free first consultation, a review of the case and a question set agreed with you before anything begins.
Every quote covers the online consultation, the design of the questions, the examinee's voluntary written consent, the examination on certified equipment, a verbal preliminary result on the day, and a full written report. A mutual NDA is available on request for corporate clients. What we never do is quote low and "settle up" afterwards — the price you agree is the price you pay.
We settle in USDT (a US-dollar stablecoin), which keeps pricing consistent across 40+ countries and is convenient for international and Russian-speaking clients. On each country's own page you'll also see an indicative local-currency figure — pounds, euros, Canadian dollars and so on — rounded up for guidance, so you can gauge the cost in the money you actually use.
Tell us the country, the format and how many people are involved, and we'll give you an exact price with no obligation — and it won't change on the invoice later. We work in English and Russian.
