A membership share savings account is a savings product offered by credit unions, not banks

When you open a savings account at a credit union, you are not just depositing money — you are buying a share of the credit union itself. That account is called a membership share savings account, and it works differently from a bank savings account in one important way: your money is insured by the National Credit Union Administration (NCUA), a federal agency, rather than by the Federal Deposit Insurance Corporation (FDIC) that insures bank accounts.

The account functions like a regular savings account in most respects. You deposit money, earn interest, and withdraw when you need to. The difference is structural: credit unions are member-owned cooperatives, so when you open the account, you become a part-owner. Your savings account is technically a share of that ownership, which is why it has the word "share" in its name.

You do not need to understand the ownership structure to use the account. What matters is that NCUA insurance covers up to $250,000 per account category at each credit union, the same limit as FDIC coverage at banks. If the credit union fails, your money is protected.

Key Takeaways

  • A membership share savings account at a credit union makes you a part-owner of that credit union, unlike a bank savings account where you are a customer.
  • NCUA insurance protects your money up to $250,000 per account category, the same protection level as FDIC insurance at banks.
  • Interest rates and fees vary by credit union, so comparing accounts across different credit unions can help you find better terms than your bank offers.
  • You must meet membership requirements to open an account, which usually means living in a certain area, working for a specific employer, or belonging to an organization — requirements vary widely.

How membership requirements work

Credit unions are not open to everyone the way banks are. Each credit union has a field of membership that defines who can join. This might be people who live in a specific county, work for a particular employer, belong to a union or professional organization, or attend a certain school or church. Some credit unions have broad fields of membership; others are very narrow.

Before you can open a membership share savings account, you have to meet the credit union's membership requirements. If you do not meet them, you cannot open an account there, even if you have money to deposit. Some credit unions let you join if you have a family member who already belongs, or if you donate to a related nonprofit organization.

Once you meet the membership requirement and open the account, you remain a member as long as the account stays open. You do not have to do anything special to maintain membership — simply keeping the account active is enough.

Interest rates and minimum balances

Credit unions typically offer higher interest rates on savings accounts than banks do, though this varies depending on the credit union and the current economic environment. Some credit unions offer tiered rates, meaning the interest rate increases as your balance grows. Others offer a flat rate regardless of balance.

Minimum balance requirements also vary. Some credit unions require you to keep a minimum amount in the account at all times — often $25 to $100 — while others have no minimum. If your balance falls below the minimum, you may lose the interest rate or be charged a monthly fee. Check the credit union's account terms before opening to understand what they require.

Because credit unions are member-owned and nonprofit, they often return profits to members through higher rates or lower fees rather than paying shareholders. This is one reason credit union savings accounts sometimes offer better terms than bank accounts, though you should compare specific offers rather than assuming one is always better.

NCUA insurance and account protection

Your membership share savings account is insured by the NCUA up to $250,000. This means if the credit union fails, the NCUA will reimburse you for your balance up to that limit. The $250,000 limit applies per account category at each credit union, so if you have both a savings account and a money market account at the same credit union, each is insured separately up to $250,000.

If you have accounts at multiple credit unions, each account is insured separately. For example, if you have $200,000 at Credit Union A and $200,000 at Credit Union B, both amounts are fully protected because they are at different institutions.

Joint accounts — accounts held in the names of two or more people — are insured separately from individual accounts. A joint membership share savings account is insured up to $250,000 for the account itself, and each owner's individual account at the same credit union is insured up to another $250,000.

Differences from a regular bank savings account

The main practical differences between a membership share savings account and a bank savings account are membership requirements, insurance provider, and sometimes interest rates. You cannot open a credit union account without meeting the field of membership; you can open a bank account with almost no restrictions. Your credit union account is insured by NCUA; a bank account is insured by FDIC. Credit unions sometimes offer better rates, but not always.

Both types of accounts work the same way from a user perspective: you deposit money, earn interest, and withdraw when you need to. Both offer debit cards, online banking, and mobile apps. Both allow you to set up automatic transfers. The ownership structure is different, but the day-to-day experience is similar.

One practical difference: credit unions are often smaller than banks, so they may have fewer branches and ATMs. However, many credit unions participate in shared branching networks and ATM networks that let you access your account at other credit unions' locations. Ask your credit union whether it participates in these networks if branch access matters to you.

How to find a credit union you can join

The CO-OP Network and Alliant Credit Union's shared branching network are two large networks that let you search for credit unions by location or membership category. The Credit Union Locator tool on the NCUA website also lets you search by zip code or employer.

Start by checking whether your employer offers a credit union, whether you live in an area served by a community credit union, or whether you belong to any organization — union, professional association, alumni group, religious organization — that sponsors a credit union. Many people are surprised to find they already meet the membership requirements for at least one credit union.

Once you find a credit union you can join, compare their membership share savings account terms: interest rate, minimum balance, monthly fees, and whether they participate in shared branching or ATM networks. Some credit unions offer higher rates but charge monthly fees; others offer lower rates but have no fees. Calculate which is better for your expected balance.

Frequently Asked Questions

Do I have to buy a share to open a membership share savings account?

No. The account itself is your share. Some credit unions charge a one-time membership fee (usually $5 to $25) when you open your first account, but this is separate from the account. You do not purchase shares separately or pay ongoing share fees.

What happens to my membership if I close the account?

Your membership ends when you close your last account at the credit union. Some credit unions allow you to maintain membership with a very small balance ($1 to $5) if you want to keep the membership active without using the account, but this varies. Ask your credit union about their policy if you think you might want to rejoin later.

Can I have multiple membership share savings accounts at the same credit union?

Yes. You can open more than one savings account at the same credit union if you want to organize your money into separate accounts — for example, one for emergency savings and one for a specific goal. Each account is insured separately up to $250,000.

Is a membership share savings account safer than a bank savings account?

Both are equally safe in terms of insurance protection. NCUA insurance and FDIC insurance both protect up to $250,000 per account category. The difference is the insurer, not the level of protection. Choose based on membership requirements, interest rates, and convenience rather than safety.

Can I use a membership share savings account like a checking account?

No. A membership share savings account is designed for saving, not frequent spending. Federal regulations limit you to six withdrawals per month (though this rule is not always enforced). If you need frequent access to your money, open a credit union checking account in addition to your savings account.
