A share account and a savings account are not the same thing, though the names are sometimes used interchangeably

A share account is a membership account at a credit union. When you open one, you own a share of the credit union itself—you are part-owner of the institution. A savings account is a deposit account at a bank where you lend money to the bank and earn interest on it. The credit union holds your money in trust as a member; the bank holds your money as a debtor. This difference matters because it changes how your money is insured, what fees you pay, and what happens if the institution fails.

Credit unions often call their basic membership account a "share account" or "share savings account" to reflect that you own a piece of the credit union. Banks call theirs a savings account because you are depositing funds with them. Some credit unions use both terms—a share account for membership and a share savings account for interest-bearing deposits. The confusion is real, and it happens because credit unions and banks use different language for similar products.

Key Takeaways

  • A share account at a credit union makes you a member-owner of the institution, while a savings account at a bank makes you a creditor with a deposit.
  • Both are insured up to $250,000 by the NCUA (credit unions) or FDIC (banks), but the insurance is separate—you cannot combine the two to insure more money.
  • Credit unions typically charge lower fees and offer lower minimum balances than banks, but availability and online features vary widely.
  • Interest rates on share accounts and savings accounts fluctuate with the market and depend on the specific institution, not the account type itself.
  • If you want to join a credit union, you must meet membership requirements—you cannot straightforward open a share account like you can open a bank savings account.

How ownership and deposit insurance differ

When you open a share account at a credit union, you purchase at least one share of the credit union's stock. The minimum share price varies—often $5 to $25—but once you own that share, you are a member. You have voting rights in the credit union's elections and a claim on the institution's assets. If the credit union fails, your deposits are insured by the National Credit Union Administration (NCUA) up to $250,000 per account category.

A savings account at a bank is different. You are not buying ownership; you are depositing money that the bank uses to make loans. The bank pays you interest on your deposit. If the bank fails, your deposits are insured by the Federal Deposit Insurance Corporation (FDIC), also up to $250,000 per account category. The insurance covers you either way, but the legal relationship is different—you own part of a credit union; you are a creditor of a bank.

This matters if you have money at both institutions. NCUA and FDIC insurance do not combine. If you have $250,000 in a credit union share account and $250,000 in a bank savings account, both are fully insured. If you have $400,000 in a credit union, only $250,000 is covered by NCUA insurance. The remaining $100,000 is not insured at all.

Fees, minimums, and interest rates

Credit unions generally charge lower fees than banks. Many credit unions have no monthly maintenance fee on share accounts, while banks often charge $5 to $15 per month unless you maintain a minimum balance or set up direct deposit. Minimum opening balances at credit unions are typically $5 to $25; at banks, they range from $0 to $500 depending on the account type and institution.

Interest rates on both share accounts and savings accounts move with the market. The Federal Reserve sets the benchmark rate, and institutions adjust their rates in response. A credit union share account might pay 4.5% annual percentage yield (APY) at one credit union and 3.8% at another. The same variation exists at banks. The account type—share versus savings—does not determine the rate. The institution's strategy and competition in your area do.

Overdraft fees, ATM fees, and wire transfer fees vary by institution, not by account type. Some credit unions charge nothing for overdrafts; some banks charge $35. Some credit unions have nationwide ATM networks; others have limited access. Read the fee schedule and terms for the specific account at the specific institution you are considering.

Credit union membership requirements

You cannot open a share account at just any credit union. Credit unions have field of membership requirements—you must meet one to join. Common fields include working for a specific employer, living in a specific geographic area, belonging to a specific profession or organization, or having a family member who is already a member. Some credit unions have broad fields; others are narrow. A credit union for teachers will not let you join unless you work in education or are related to someone who does.

Banks have no membership requirement. You can walk into any bank branch and open a savings account if you have an ID and a Social Security number. This is a real advantage if you do not meet any credit union's field of membership or if you want to open an account quickly without checking may be able to access.

If you do meet a credit union's membership requirement, joining is straightforward. You complete a membership process, purchase at least one share, and the share account is open. The share purchase is not an investment—it is a one-time fee that stays in your account and earns interest like any other balance.

When to choose each type

Choose a credit union share account if you meet the membership requirement and want lower fees, a lower minimum balance, and a sense of ownership in the institution. Credit unions are member-owned cooperatives, so profits go back to members through better rates and lower fees rather than to shareholders. If you do not carry a balance and rarely use services beyond deposits and withdrawals, the fee difference can add up over time.

Choose a bank savings account if you do not meet any credit union's membership requirement, need access to many branches or ATMs, or want the widest range of online and mobile features. Large banks have more resources for technology and customer service. If you are moving frequently or need accounts in multiple states, a national bank may be more convenient than a credit union with limited branches.

You do not have to choose one or the other. Many people have both a credit union share account and a bank savings account. You might use the credit union for everyday banking and the bank for a second savings goal, or vice versa. Just remember that NCUA and FDIC insurance are separate—money at each institution is insured independently up to $250,000.

How to find out which one you have

Check your account opening documents or log into your online account. The institution's name will tell you: if it says "Credit Union" in the name, you have a share account (or share savings account). If it says "Bank," "Trust," or "Savings Bank," you have a savings account. Your monthly statement will also say whether you are a member of a credit union or a customer of a bank.

If you are unsure, call the institution's customer service line and ask. They will tell you when ready whether your account is a share account or a savings account and what that means for your insurance coverage and any membership rights you have.

Frequently Asked Questions

Can I move money between a share account and a savings account?

Yes. You can transfer money from a credit union share account to a bank savings account and vice versa using an external transfer, ACH transfer, or wire transfer. The accounts are at different institutions, so the transfer takes one to three business days. There is no limit on how often you transfer between them.

Do share accounts have the same withdrawal limits as savings accounts?

Historically, savings accounts had federal limits on withdrawals, but those rules changed in 2020. Now both share accounts and savings accounts allow unlimited withdrawals. Some institutions may still limit transfers out of savings accounts to six per month, but withdrawals at the branch or ATM are unlimited at both types of accounts.

If a credit union fails, do I lose my share?

No. Your share and any balance in your share account are insured by the NCUA up to $250,000 total. If the credit union fails, the NCUA takes over and either merges the credit union with another or pays out your insured balance. You will not lose money up to the insurance limit.

Can I earn interest on a share account?

Yes. Most credit unions pay interest on share accounts, though the rate varies by institution and market conditions. Some credit unions call interest-bearing accounts "share savings accounts" to distinguish them from non-interest-bearing share accounts, but both are membership accounts.

What happens to my share account if I close it?

When you close a share account, the credit union returns your share purchase (usually $5 to $25) along with any balance and accrued interest. You are no longer a member of the credit union unless you maintain another account there or the credit union has other membership categories.
