Is Mensa Worth It? Honest Pros, Cons and Costs (US, UK, CA)
Is Mensa worth it? It's worth it if you want a social club of curious people, local meetups and events, and you'll actually show up. It's not worth it if you mainly want a line on your CV or proof you're smart: most employers and universities won't care. Mensa is legit (not a scam), the only entry rule is scoring in the top 2% on an approved test, and costs are an annual fee plus a testing fee that varies by country.
Before you pay for a supervised test, it helps to know how your reasoning actually stacks up. IQ Tester shows your score band and reasoning strengths in 20 untimed questions: Find my weak spots.

What Mensa membership actually gives you
Mensa is a nonprofit high-IQ society founded in England in 1946. Today it runs as Mensa International with national groups, including American Mensa, British Mensa and Mensa Canada.
What members typically get (details vary by country):
- Local meetups: game nights, dinners, talks, pub quizzes.
- Special interest groups (SIGs): online and in-person groups around hobbies, from sci-fi to chess to languages.
- Gatherings: regional and national events with talks and socials.
- A members' magazine and online community.
- Some member discounts, depending on the national group.
What you don't get: a job, a scholarship by default, or any official say that you're "gifted." Mensa's own framing is that it's a social society.
Is Mensa legit or a scam?
Mensa is legit. It's a long-running nonprofit with published entry rules. What is sometimes scammy: random "free Mensa IQ test" sites that aren't connected to Mensa and charge you for a certificate. Official entry only comes through a national Mensa's supervised test or an approved prior test score.
Costs and entry rules in the US, UK and Canada
How much IQ do you need to join Mensa?
You need to score at or above the 98th percentile, meaning the top 2%, on an approved intelligence test. On many common IQ scales with a standard deviation of 15, that works out to roughly 130 or a bit higher. The exact number depends on the test, which is why Mensa talks about percentiles, not one magic IQ.
How much does it cost to join Mensa?
There are usually two costs:
- Testing fee: for sitting a supervised Mensa admission test (or a smaller fee to submit an approved prior score).
- Annual membership dues: paid every year you stay a member.
Fees change and differ between countries, so check the current price on the official site before you book. Don't trust a price you saw in a years-old Reddit thread.
Country by country
| American Mensa (US) | British Mensa (UK) | Mensa Canada | |
|---|---|---|---|
| Entry rule | Top 2% on an approved test | Top 2% on an approved test | Top 2% on an approved test |
| Ways in | Supervised test or approved prior score | Supervised test or approved prior score | Supervised test or approved prior score |
| Costs | Test fee + annual dues | Test fee + annual fee | Test fee + annual fee |
| Where to check | us.mensa.org | mensa.org.uk | mensacanada.org |
So yes, Mensa is in the UK and yes, Mensa is in Canada, each with its own sessions and fees.
Can teens join?
Usually yes, but the route depends on your age and country.
- In the US, American Mensa's own supervised test has historically been for ages 14 and up. Younger kids typically qualify by submitting a score from an approved test taken with a school or private psychologist.
- In the UK, British Mensa has run supervised sessions for children from around age 10 and a half, with separate options for younger children.
- In Canada, check Mensa Canada's current rules for young applicants.
Rules can change, so treat this as a starting point, not the final word.
What teens actually get: some national groups run youth programs, competitions or family events. But a lot of Mensa's social life is aimed at adults, so ask your local group what's on for under-18s before you pay.
The downsides nobody mentions
The honest cons, straight from the kind of stuff people post on "is Mensa worth it Reddit" threads:
- It depends on your local group. Big city? Probably lively. Small town? Maybe three people and a board game.
- It won't impress most employers. Some recruiters see it as neutral; a few see it as a flex. Put your projects on your CV instead.
- Membership isn't free, forever. Annual dues add up.
- The label can backfire. If being "smart" is your whole identity, a high-IQ card can make that worse. (See our post on former gifted kid syndrome.)
- IQ isn't everything. Plenty of brilliant people have average EQ; social skills still matter. More in high IQ low EQ.
- The test is one day of your life. Bad sleep, nerves or a noisy room can knock your score.
Try a reasoning test first
Here's a cheap way to decide if the Mensa test is worth it: get a rough read of your reasoning first, see where you're strong and where you're shaky, and practice the shaky bits before booking.
Guessing where you'd land is the hard part. You can't tell from vibes whether pattern questions or number series will trip you up on test day. IQ Tester runs 20 untimed questions across number series, verbal analogy, logic and pattern, weights hard questions more, and shows which categories are your strengths. It's for entertainment, not an official Mensa score, but it tells you what to practice. Find my weak spots
