A share certificate is the credit union equivalent of a bank’s certificate of deposit (CD). It’s a low-risk savings product where you deposit a set amount for a fixed term and earn a guaranteed interest rate, usually higher than what you’d get from a regular savings account.

Because share certificates are insured by the National Credit Union Administration (NCUA) up to $250,000, they offer a safe way to grow your money without market volatility. They work well for savers who can leave their funds untouched for the full term in exchange for higher yields.
If you’re looking for predictable returns, protection on your principal, and a simple way to earn more on your savings, a share certificate could be a smart addition to your financial plan.
Key Takeaways
- A share certificate is a credit union savings product similar to a bank CD, where members deposit a set amount for a fixed term and earn a guaranteed rate, often higher than standard savings accounts.
- They offer secure, NCUA-insured returns with the benefit of compound interest, but funds are locked in for the term and early withdrawals trigger penalties.
- Best suited for a low-risk portfolio, share certificates require credit union membership and can sometimes be used as collateral for loans.
What a Share Certificate Is and When to Use One
A share certificate is a fixed-term deposit offered by credit unions, similar to a bank certificate of deposit (CD). Members deposit a set amount for a predetermined term, and the credit union pays a fixed interest rate—often higher than regular savings accounts. These accounts are insured by the National Credit Union Administration (NCUA) up to $250,000, making them a secure way to earn predictable returns.
Share certificates work best when you can commit to leaving your money untouched for the full term. They’re a good fit for savers who want a guaranteed rate without the volatility of the stock market, and they can also be used as collateral for certain credit union loans.
How Share Certificates Work
Before opening a share certificate, it helps to understand how it functions within a credit union. Here’s a breakdown of the key elements:
- Initial investment: You deposit a set amount that meets the credit union’s minimum requirement. This amount is locked in for a term ranging from a few months to several years.
- Fixed interest rate: The rate stays the same for the entire term, providing predictable returns and protection from market fluctuations.
- Term lengths: Choose a term that fits your goals. Longer terms usually offer higher rates, though promotions may make shorter terms more competitive.
- Compound interest: Interest is reinvested, allowing your balance to grow faster over time through “interest on interest.”
- Maturity and renewal: At the end of the term, withdraw your funds with interest or roll them into a new certificate. Many credit unions offer automatic renewal.
- Early withdrawal: You can access your funds before maturity, but penalties will reduce your earnings and may affect your principal.
How to Get a Share Certificate
To open a share certificate, you must first join a credit union by meeting its membership criteria, such as living in a certain area, working for a specific employer, or paying a small membership fee. Once you’re a member, you’ll need:
- An initial deposit that meets the minimum balance requirement
- A chosen term length that fits your savings goals
- Standard identification for account setup
Compare rates, terms, and penalties before opening an account, and check whether your credit union offers competitive promotions.

Pros & Cons of Share Certificates
Like any savings product, share certificates have advantages and drawbacks. Knowing both can help you decide whether they fit your financial goals.
Pros
- Fixed interest rate: Often higher than savings or money market accounts, providing predictable growth.
- NCUA insurance: Protects deposits up to $250,000 per account holder, per account type.
- Higher annual percentage yield (APY): Can deliver steady earnings if you keep your money invested for the full term.
Cons
- Early withdrawal penalties: Can reduce or eliminate earned interest, and in some cases affect your principal.
- Low liquidity: Funds remain locked until maturity unless you pay a penalty for early access.
Share Certificates in Your Investment Portfolio
Share certificates work well as the stable portion of a diversified portfolio. Their low-risk, fixed-rate structure can offset the ups and downs of more volatile investments like stocks. They’re ideal for funds you don’t need immediate access to but still want to grow at a predictable rate.
Share Certificates vs. Other Savings Options
- Savings accounts: Offer more liquidity but generally pay lower interest than share certificates.
- Money market accounts: May earn slightly higher rates than savings accounts, but still usually trail share certificates.
- Stock certificates: Represent company ownership and carry higher risk, while share certificates are deposit accounts with guaranteed returns.
Share Certificates vs. Certificates of Deposit (CDs)
Share certificates and certificates of deposit (CDs) are nearly identical in how they work, but they’re offered by different types of institutions. Share certificates come from credit unions and require membership, while CDs are issued by banks and are available to any customer. Both pay a fixed interest rate for a set term, lock in your funds until maturity, and impose penalties for early withdrawals.
Feature | Share Certificate | Certificate of Deposit (CD) |
---|---|---|
Institution type | Offered by credit unions | Offered by banks |
Membership requirement | Must be a credit union member | No membership required |
Insurance coverage | Insured by NCUA up to $250,000 per account holder, per account type | Insured by FDIC up to $250,000 per depositor, per account type |
Interest rates | Often higher than CDs, especially at smaller or community credit unions | Can be competitive, but rates vary by bank |
Withdrawal rules | Funds locked until maturity; early withdrawals incur penalties | Same — locked until maturity; early withdrawals incur penalties |
Renewal options | Often offers automatic renewal at maturity | Often offers automatic renewal at maturity |
If you already belong to a credit union, a share certificate may offer better rates than a CD from a traditional bank. If you’re not eligible for credit union membership, a CD can provide a similar return and security.
Conclusion
For savers seeking safety, predictable earnings, and higher yields than a typical savings account, share certificates can be a strong choice. Match the term length and interest rate to your financial goals, and weigh the impact of early withdrawal penalties before committing.
Compare offers from multiple credit unions, as rates and terms can vary widely. If the numbers work for you, a share certificate can be a dependable way to grow your money while keeping it protected.
Frequently Asked Questions
Can you lose money on a share certificate?
No, as long as your credit union is federally insured. Share certificates are protected by the NCUA up to $250,000 per account holder, per account type, making them a very safe place to keep your money.
Can you add funds to a share certificate after the initial deposit?
In most cases, no. Once you open a share certificate, you cannot add more money until it matures. If you want to continue saving, you’ll need to open a new certificate or use another account type that allows ongoing deposits.
Are the interest rates for share certificates negotiable?
No. The interest rate is fixed when you open the certificate and cannot be changed. Rates are set by the credit union based on the term length, deposit amount, and overall market conditions.
Do share certificates automatically renew upon reaching maturity?
Often, yes. Many credit unions automatically roll your funds into a new certificate when the term ends, but this is not always the case. Check your credit union’s policy before maturity so you can decide whether to renew or withdraw.
Can you use a share certificate as collateral for a loan?
Yes. Many credit unions allow you to pledge your share certificate as collateral for a personal loan, auto loan, or other credit union financing, which can help you qualify for a lower interest rate.
