What a membership share savings account actually is
A membership share savings account is a savings account held at a credit union, not a bank. When you open one, you are buying a share of the credit union itself — that share is what gives you membership. The account holds your money and earns interest, but the "share" part means you own a small piece of the organization. Credit unions are owned by their members, not by shareholders or investors outside the organization.
The practical difference from a bank savings account is smaller than it sounds. You deposit money, it sits there earning interest, you can withdraw it. The main differences are that credit unions tend to offer lower fees, sometimes pay slightly higher interest rates, and have stricter rules about who can join — you usually have to meet a membership requirement like working for a specific employer, living in a certain area, or belonging to a particular group.
The word "share" is just the credit union's term for what a bank calls a deposit. It does not mean you own stock or that your account value fluctuates with market conditions. Your balance stays exactly what you put in, plus interest.
Key Takeaways
- Membership share savings accounts are held at credit unions, and opening one makes you a partial owner of that credit union.
- Your money earns interest just like a bank savings account, and the balance does not change based on market conditions.
- Credit unions require you to meet a membership criterion — usually employment, location, or group affiliation — before you can open an account.
- Deposits in membership share accounts are insured up to $250,000 by the National Credit Union Administration (NCUA), the same way bank deposits are insured by the FDIC.
How membership and ownership actually work
When you open a membership share savings account, the credit union issues you one share — usually worth $25 or $5, depending on the credit union. That share is the price of membership. You own it for as long as you are a member. If you close the account, the credit union refunds that share value to you, usually by check or direct deposit.
Because you own a share, you have voting rights on credit union decisions — you can vote on the board of directors and on major policy changes. In practice, most members never vote, but the right exists. You also have access to the credit union's services, which usually include savings accounts, checking accounts, loans, and sometimes credit cards or investment products.
The credit union uses the money you deposit to make loans to other members, and the interest from those loans funds the organization. Any profit left over after expenses is returned to members as dividends or reinvested in lower fees and better rates. This is why credit unions often have lower fees than banks — they are not trying to maximize profit for outside shareholders.
Interest rates and how they compare to banks
Membership share savings accounts earn interest, but the rate varies by credit union and changes over time. Some credit unions pay rates slightly higher than banks offer on comparable accounts; others pay roughly the same. The rate depends on the credit union's size, location, and how much money they have available to lend.
Interest is usually compounded daily or monthly, meaning you earn interest on your interest. The credit union will tell you the Annual Percentage Yield (APY) when you open the account — that is the rate you will actually earn after compounding is factored in. Rates change, so check with your specific credit union for current numbers rather than comparing to another institution's rate.
Some credit unions offer tiered rates, meaning you earn more interest if you keep a higher balance. Others offer the same rate regardless of balance. A few offer promotional rates for new members or new deposits, though these usually last only a few months.
Membership requirements and who can join
Credit unions are not open to everyone — you have to meet at least one membership criterion. The most common are: you work for a specific employer or industry, you live in a specific geographic area, you belong to a specific organization or group, or you are related to someone who already belongs. Some credit unions have multiple pathways to membership, so you might may have access to through your job, your zip code, or your alumni status.
To learn about you can join a specific credit union, visit their website or call and ask what membership requirements they have. They will tell you directly whether you meet one. If you do not meet any requirement at a credit union you want to use, you can usually find another one in your area with different requirements — most areas have multiple credit unions.
A few credit unions have very broad membership — for example, some allow anyone in a multi-state region to join, or anyone who works in a certain industry nationwide. If you cannot find a credit union that fits your situation, the CO-OP Network (a shared branching system) and Allpoint ATM network mean you can access many credit union branches and ATMs even if your own credit union is small or distant.
NCUA insurance and what happens if the credit union fails
Deposits in membership share savings accounts are insured by the National Credit Union Administration (NCUA), a federal agency that works the same way the FDIC does for banks. Your account is covered up to $250,000 per account type, per credit union. If the credit union fails, the NCUA steps in and makes sure you get your money back.
The NCUA insurance covers your membership share account separately from other account types at the same credit union. So if you have a membership share savings account and a checking account at the same credit union, each is insured up to $250,000. If you have multiple savings accounts at the same credit union, they are added together and the total is insured up to $250,000.
Credit union failures are rare, and when they do happen, members almost always recover their full balance. The NCUA maintains a fund specifically for this purpose, and it is well-capitalized. You do not need to do anything to set up this insurance — it is automatic the moment you open the account.
Fees and minimum balance requirements
Membership share savings accounts usually have lower fees than bank savings accounts, or no fees at all. Some credit unions charge a monthly maintenance fee (typically $2 to $5), but many waive it if you keep a minimum balance or set up direct deposit. A few charge nothing regardless.
Minimum balance requirements also vary. Some credit unions require you to keep $25 or $100 in the account at all times; others have no minimum. If you fall below the minimum, the credit union may charge a fee or close the account. Check your credit union's fee schedule when you open the account — it should be in writing or available on their website.
Withdrawal limits are rare on membership share savings accounts, though some credit unions restrict how many times per month you can withdraw without a fee. Federal rules used to limit savings account withdrawals to six per month, but that rule was suspended in 2020 and has not been reinstated. Most credit unions now allow unlimited withdrawals, but confirm this with your credit union before opening.
How to open a membership share savings account
To open an account, first confirm you meet the credit union's membership requirements. Then visit a branch in person, call, or go to their website — most credit unions now allow online applications. You will need a government-issued ID, proof of address (usually a recent utility bill or lease), and your Social Security number.
The credit union will run a background check through ChexSystems or Early Warning Services, which are banking history databases. This is not a credit check and does not affect your credit score. If you have been flagged for fraud or have unpaid fees at another bank, the credit union may decline you, but this is rare.
Once approved, you will fund the account with your initial deposit. The credit union will issue your membership share (usually $25 or $5) and your account will be active. You can start depositing money and earning interest when ready. Most credit unions provide a debit card and online banking access within a few days.
Frequently Asked Questions
Can I lose money in a membership share savings account?
No. Your balance is insured by the NCUA up to $250,000, and you earn interest on what you deposit — you do not lose money based on market conditions or credit union performance. The only way your balance goes down is if you withdraw money or if the credit union charges a fee that exceeds your interest earnings.
What happens to my membership share if I close the account?
The credit union refunds the value of your share, usually within a few days to a week. If you opened with a $25 share, you get $25 back. This is separate from your account balance — you get both your share refund and your deposit back.
Can I have multiple membership share accounts at the same credit union?
Most credit unions allow you to open multiple savings accounts, but you only buy one membership share. Additional accounts are just regular savings accounts linked to your existing membership. Each account is insured separately up to $250,000.
Do I have to vote or participate in credit union decisions?
No. Voting is a right you have as a member, but it is not required. Most members never vote. You can straightforward use your account and ignore the membership aspect entirely.
What is the difference between a membership share account and a regular savings account at a bank?
The main difference is ownership — you own a piece of the credit union, and credit unions are typically nonprofit. This usually means lower fees and sometimes higher interest rates. The practical experience of saving money is nearly identical: you deposit, earn interest, and withdraw as needed.
