What is a credit union share / savings membership deposit?
A credit union share account (often called primary savings or membership share) is the small deposit that establishes your ownership stake in the cooperative. The published minimum — commonly $1, $5, or $25 on Joinable listings — is a membership requirement, not an annual fee.
Why it exists
Credit unions are cooperatives. Buying at least one share at par value makes you a member-owner with voting rights under the CU’s bylaws. Banks do not use this structure.
Amounts on Joinable
We cite share/join dollars only when the CU publishes them (examples: Amplify $5, Neighborhood $25, River City $5). If not published, we say so — we never invent.
Keep the minimum
Many CUs require the share minimum to remain on deposit for membership to stay open. Closing the share usually ends membership.
Share vs monthly fees vs association dues
- Share — ownership deposit.
- Monthly maintenance — product fee if published on a checking schedule.
- Association / foundation dues — separate published join cost (e.g. PECU $5 membership fee, A+ $10 foundation).
