Primary Shares is not a savings account—it's a share of ownership in a credit union
When you open an account at a credit union, you are required to buy at least one primary share. This share represents partial ownership in the credit union itself. The minimum cost is typically between $5 and $25, depending on the credit union. You own this share for as long as your account is open.
A savings account at that same credit union is separate. It is a deposit account where you store money and earn interest. The primary share is not where your money sits or grows. It is a membership requirement that sits in the background.
The confusion happens because credit unions sometimes bundle the primary share and a savings account together under one account number, or they may call the savings portion "share savings" to reflect the credit union structure. But they function differently and serve different purposes.
Key Takeaways
- A primary share is a required ownership stake in a credit union, not a place to deposit money or earn interest.
- You must buy at least one primary share to become a member, usually for $5 to $25 depending on the credit union.
- Your actual savings deposits go into a separate savings account, which earns interest and is where you withdraw money from.
- The primary share remains in your account as long as you are a member and cannot be withdrawn like savings can be.
- Credit unions may use the term "share savings" for their savings accounts to reflect the cooperative ownership structure, but this is still a deposit account, not the primary share itself.
Why credit unions require a primary share
Credit unions are member-owned cooperatives, not corporations. When you buy a primary share, you become a legal member and owner. This is how credit unions maintain their structure and governance. Members vote on policies, elect the board, and share in the credit union's profits through dividends or lower fees.
The primary share is the legal mechanism that makes this work. Without it, you would be a customer, not a member. The amount you pay is intentionally small—$5 to $25—because the goal is membership, not fundraising. The credit union is not trying to collect large sums this way.
How primary shares and savings accounts work together
When you join a credit union, you typically complete one process that sets up both your primary share and your savings account. The primary share is purchased first, using the minimum amount required. Any additional money you deposit goes into your savings account.
Your savings account earns interest at whatever rate the credit union offers. You can deposit and withdraw from savings freely. The primary share sits untouched. If you close your account, the credit union returns your primary share value to you, usually as a check or transfer.
Some credit unions allow you to buy additional shares beyond the primary share, which functions similarly—as an ownership stake rather than a savings vehicle. But the primary share is the one required for membership.
What happens to your primary share if you leave
If you close your account at the credit union, you can request that your primary share be returned to you. The credit union will refund the amount you paid—typically $5 to $25. This is not a withdrawal of earnings; it is a return of your membership stake.
If your account sits inactive for a long period, the credit union may close it and return your primary share automatically. The exact timeline varies by credit union and is stated in their account agreement. Some credit unions charge an inactivity fee, which would be deducted from your savings account, not your primary share.
Primary shares versus share certificates and money market accounts
Credit unions offer other products that use the word "share" but function differently. A share certificate is similar to a certificate of deposit (CD) at a bank—you deposit money for a fixed term and earn a set interest rate. A share money market account is like a money market account at a bank, with variable interest rates and limited withdrawals per month.
Neither of these is your primary share. Your primary share remains the required $5 to $25 membership stake. The share certificate and share money market account are optional savings products you can choose to open in addition to your primary share and regular savings account.
| Product | Purpose | Required? | Can You Withdraw? |
|---|---|---|---|
| Primary Share | Membership ownership stake | Yes | Only when closing account |
| Share Savings Account | Deposit and earn interest | Usually | Yes, anytime |
| Share Certificate | Fixed-term savings with set rate | No | After term ends (penalties if early) |
| Share Money Market Account | Variable-rate savings with limited access | No | Limited per month |
How to tell if your credit union account includes a primary share
Check your account statement or the account agreement you received when you opened the account. The primary share will be listed separately from your savings balance. It may appear as a line item showing the amount ($5, $10, $25, etc.) and labeled as "Primary Share," "Share," or "Membership Share."
If you are unsure, contact your credit union directly. They can confirm whether your account includes a primary share and what the amount is. You can also ask whether you have additional shares beyond the primary share, which some members purchase over time.
Frequently Asked Questions
Can I withdraw my primary share whenever I want?
No. Your primary share must remain in your account as long as you are a member. You can only withdraw it when you close your account entirely. If you need access to money, use your savings account instead.
Do I earn interest on my primary share?
Some credit unions pay a small dividend on primary shares, but most do not. Check your account agreement or ask your credit union. Any interest you earn will be on your savings account, not your primary share.
What if I want to leave the credit union but keep my savings?
You can transfer your savings to another account at a different bank or credit union. When you close your credit union account, your primary share will be returned to you. The two transactions are separate.
Is my primary share protected if the credit union fails?
Yes. The National Credit Union Administration (NCUA) insures deposits at federally chartered credit unions up to $250,000 per account category. Your primary share and your savings account are typically in the same category, so the combined total is insured up to $250,000.
Can I have a credit union account without a primary share?
No. A primary share is a requirement for membership at any credit union. You cannot open an account without purchasing one. However, the cost is minimal—usually $5 to $25—and you get it back if you close the account.
