One of the most common questions people ask before booking a lie detector test is: “How much does it cost?” The answer depends on several factors, including the type of test, the examiner’s qualifications, travel requirements, and what’s included in the service.
In this post, we break down what you can expect to pay for a polygraph test in South Africa, what those fees cover, and why going with the cheapest option could cost you more in the long run.
💰 Typical Price Range for Polygraph Tests
In South Africa, the average polygraph test typically costs between R750 and R1500 per person, depending on:
- The type of test (e.g. single-issue, pre-employment, multiple-issue)
- Whether the test is on-site or off-site
- The examiner’s experience and credentials
- Travel costs if the examiner is coming to your location
⚠️ Be cautious of anyone offering tests below R700. This usually signals inexperience, outdated equipment, or rushed procedures — all of which compromise reliability.
🧾 What’s Usually Included in the Price?
A professional polygraph test fee should include:
| Included in the Cost | Description |
| Pre-test Interview | Explains the test process and screens the subject for suitability |
| Customised Test Format | Designed specifically for your case or concern |
| Actual Polygraph Test | Conducted using modern, calibrated equipment |
| Video & Audio Recording | The full test session is documented for quality assurance |
| Written Report | Clear, easy-to-understand results are sent after the test |
| Confidentiality | Full protection of client and subject information |
Some examiners may offer optional add-ons like consultations, result reviews, or follow-up support, which could affect pricing slightly.
💼 Business vs. Private Rates
- Corporate or HR Polygraph Tests: These often involve multiple candidates and may be discounted based on volume or ongoing service agreements.
- Private Clients (Relationships, Theft, Disputes): Pricing tends to be standard unless travel or urgent scheduling is involved.
- Legal Cases: These require more detailed reporting and sometimes court-admissible documentation, which can raise the cost.
📍 Does Location Affect Cost?
Yes. If the examiner needs to travel to your site, especially in rural areas, they may charge:
- Travel fee (per kilometre or flat rate)
- Accommodation cost (for multi-day or distant travel)
- Logistical surcharge (for remote or high-risk areas)
This is often the case for clients on farms, at game lodges, or at factories outside major metro areas.
🧠 Why the Cheapest Option Isn’t Always Best
While it might be tempting to book the cheapest examiner you can find, consider the risks:
- Poor testing conditions due to rushed processes or fatigue
- Inconclusive or inaccurate results
- No video evidence or written reports
- No credentials, training, or adherence to ethical standards
In sensitive cases, a flawed polygraph test could make things worse, not better.
✅ Tips for Getting Fair Pricing
- Ask for a quote before booking.
Know exactly what’s included and if there are any extra fees. - Check for credentials.
Only work with examiners certified by SAPFED, SAPPA, or APA. - Compare value, not just price.
A properly conducted test includes consultation, video, custom testing, and professional reporting. - Avoid same-day “rush jobs.”
These often skip important pre-test procedures, leading to bad data and unreliable outcomes. - Ask about discounts for bulk testing (especially for companies).
Final Thoughts
Polygraph testing isn’t a commodity — it’s an investigative tool that requires professionalism, accuracy, and care. When booking a test in South Africa, expect to invest between R750 and R1500 per person for a full-service, ethical, and trustworthy process.
Pay for peace of mind — not just a price tag.
