Mensa Test Cost: What You'll Pay to Test and Join in 2026
The Mensa test cost depends on where you take it. As of 2026, American Mensa lists $60 for a session run by a local group and $99 for private testing, while British Mensa charges £49 for its supervised test. Passing the test only earns you an invitation, and annual dues are a separate bill.
If you are wondering whether the whole thing is worth the money, it helps to see every line item before you book. This guide covers the test fee, the membership dues, what you pay if you need to retake it, and a few ways to keep the total down.
How Much Does the Mensa Test Cost?
Here are the fees published by the national organizations themselves, as checked in November 2026. Prices change, so treat the table as a snapshot and confirm on the official site before paying.
| Where | Option | Test fee | Source |
|---|---|---|---|
| United States | Local group session | $60 | American Mensa testing page |
| United States | Private testing at an approved facility | $99 | American Mensa testing page |
| United Kingdom | Supervised test, in person | £49 | British Mensa test page |
| United Kingdom | Supervised test, online | £49 | British Mensa test page |
Two things are worth noting. First, the cheapest route in the US is not the most convenient one: the $60 session runs on a schedule set by local volunteers, while the $99 option suits people who cannot make a group session. Second, older articles often quote outdated prices, so ignore any page that does not name a year or link to the official fee.
Other countries run their own national Mensa organizations with their own prices and currencies. This article only gives figures that were confirmed on the American and British sites, so check your own national group for a local number.
What the US Fees Cover
American Mensa offers two ways to take the admission test, and the price gap reflects how each one is run.
Local group testing: $60
A local group session is proctored by volunteers from your area. American Mensa calls it "the cost-effective way to qualify." You register for a date, show up, and sit the test with other candidates. The testing page also says promotional discounts will appear in your shopping cart at checkout, so check the cart before paying the full amount.
Private testing: $99
Private testing takes place at more than 400 approved testing facilities nationwide, and the exam is administered electronically. You pay more for flexibility, which helps if there is no local session near you or the dates never fit your schedule.
Time and retakes
The official page says the test takes one to two hours. It also says you may take a test or test battery once every eight weeks. The page lists no retake discount, so budget for paying the full fee again if you try a second time. Preparing before you book is the cheapest thing you can do. The related reading below explains the full process of joining, including how to book and what to expect on the day.
What the UK Fee Covers
British Mensa lists £49.00 for the Supervised IQ Test, and the online supervised version costs the same £49.00. The online test is taken from home, and the in-person test is held at test centres across the British Isles. Candidates must be over 10½ years old.
British Mensa says the in-person test gives you your IQ score, rather than a simple pass or fail. The qualifying threshold for membership is the top two percent, so the test fee buys you a result first and, if you reach the threshold, an invitation second.
If you are comparing countries, note that the US has a higher-priced private option while the UK has a single price. Exchange rates move, so convert at the day's rate rather than trusting a fixed comparison.

The Cost That Comes After the Test: Membership Dues
Passing is not the end of the spending. If you accept the invitation, you pay annual dues. American Mensa's dues page lists the following for the membership year running from April 1 to March 31:
| Membership type | Price |
|---|---|
| Primary family member, one year | $107 |
| Additional family member, one year | $72 |
| Three-year membership | $290 |
| Five-year membership | $475 |
Life membership is also offered, priced by age, from $155 for the oldest age band to $2,246 for ages 0 to 9. American Mensa states that it does not currently offer a discounted dues program.
New members do get one helpful break: joining members pay a prorated amount based on the month they join. The page shows annual dues falling from $107 in April to $35.67 in December, while January through March are charged at the full $107, with no proration. The timing of your application can therefore change your first-year bill noticeably.
For the UK, we did not find a dues figure on the official test page, so check the British Mensa site before you commit. Third-party pages quote differing amounts, and we have not repeated them here because none could be confirmed.
Adding It Up: A Realistic First-Year Budget
This table uses only the figures confirmed above, and the totals are simple arithmetic: test fee plus first-year dues for the US.
| Scenario | Test fee | First-year dues | Total |
|---|---|---|---|
| Local group test, join in April | $60 | $107 | $167 |
| Local group test, join in December | $60 | $35.67 | $95.67 |
| Private test, join in April | $99 | $107 | $206 |
| Private test, join in December | $99 | $35.67 | $134.67 |
In the US you must wait eight weeks between attempts. If you want a second try, plan for another $60 or $99. These totals leave out travel to a test site, which can matter if the nearest session is far away.
A cheaper starting point
If you simply want to know roughly where you stand before spending $60 or more, a practice test can answer that for free. The test on iq-test-official.site is not an official Mensa test and its result does not qualify you for membership, but it uses pattern-based questions in the same spirit, so it works as a low-risk warm-up. Treat the score as a rough indicator, not a prediction.
Ways to Keep the Total Down
- Choose the local group option in the US. At $60 it is $39 cheaper than private testing.
- Check the cart for promotions. American Mensa says promotional discounts appear at checkout.
- Think about timing. In the US, joining later in the membership year means paying prorated dues, as shown above.
- Prepare before you book. A second attempt means another fee, so a few weeks of practice can pay for itself.
- Look into prior evidence. The American Mensa testing page says that if you have taken all available tests without meeting the requirement, you can submit evidence of prior testing. Contact your national group for what they accept and whether any fee applies, since we could not confirm a price for that route.
Is Paying for Mensa Worth It?
That depends on what you want. If you are curious about your score, the test fee is the main cost, and the UK in-person test gives you the number itself. If you want the community, local events and special interest groups, the dues are the real price, and they recur every year. A three-year or five-year plan lowers the yearly rate in the US but asks for more money upfront.
