American Mensa's dues structure

The Mensa membership year begins April 1 and ends March 31.

By accepting membership in American Mensa, members agree to abide by all the requirements of the Constitution of Mensa, the Bylaws of American Mensa, Ltd., and the resolutions adopted by the American Mensa Committee, as required by section III.C.1.a. of the Constitution of Mensa.

Additional Mensan family discounts

Memberships for additional Mensan family members are available for $53 per membership and may only be purchased in single-year increments. Additional family memberships do not include subscriptions to the Mensa Bulletin or to Local Group newsletters. Additional family members must live in the same household as a primary member and be members of the same Local Group.

Dues discounts and proration

American Mensa does not currently offer a discounted dues program, but joining members and members who’ve lapsed their memberships for more than one year will have their dues prorated, depending on when during the fiscal year they join. This proration also applies to three-year and five-year membership plans.
