Do Credit Unions Have CDs? Share Certificates, Rates, and Penalties

Yes, credit unions do have CDs, though they usually call them share certificates. The product is the same one you would get at a bank: a fixed deposit for a fixed term at a guaranteed rate. The main practical difference is price. As of the second quarter of 2025, the national average on a one-year certificate at a credit union was 3.05%, compared with 2.35% at commercial banks.¹

Why the Name Is Different

Federal regulations don’t let credit unions market their time-deposit products as “certificates of deposit.” A credit union account is an ownership share in a cooperative, not a bank deposit, so the official terms are “share certificate,” “certificate account,” or just “certificate.” Many credit unions still use “CD” informally on their websites because that’s what most people search for, but the account agreement itself will say share certificate.

The distinction shows up in one other place: what your earnings are called. A bank pays interest on a CD. A credit union pays dividends on a share certificate. The tax treatment is identical either way. The IRS treats credit union dividends as taxable interest, and you’ll receive a Form 1099-INT if you earn $10 or more in a year.²³

How the Rates Compare

Credit unions are nonprofit cooperatives owned by their members, while banks are for-profit companies with outside shareholders. That structural difference shows up on the rate sheet. Surplus revenue that a bank would send to shareholders goes back to credit union members through better savings rates and lower loan rates.

NCUA data from the second quarter of 2025 shows credit unions ahead of banks at every common term length on a $10,000 deposit:

3-month: 2.01% at credit unions vs. 1.56% at banks
6-month: 2.83% vs. 2.21%
1-year: 3.05% vs. 2.35%
2-year: 2.87% vs. 2.14%
3-year: 2.80% vs. 2.07%
5-year: 2.87% vs. 2.12%

Those are averages, so any single institution can land above or below the line. The pattern holds across terms though: credit unions paid roughly 0.45 to 0.75 percentage points more, with the widest spreads on mid-range terms between six months and two years.¹

How Share Certificates Work

You deposit a lump sum, choose a term, and lock in a rate that won’t change during the term regardless of what happens in the broader market. Terms typically run from three months to five years, with longer terms generally paying higher rates because you’re giving up access to the money for longer.

The rate is quoted as an annual percentage yield (APY), which already accounts for how often dividends compound. Most credit unions compound daily or monthly. Minimum deposits tend to be lower at credit unions than at banks. Many will open a certificate for $500 or $1,000, and some have no minimum at all.

Early Withdrawal Penalties

Taking money out before maturity triggers a penalty. Federal rules set only a floor: any withdrawal within the first six days must cost at least seven days’ simple interest.⁴ Beyond that, each credit union sets its own schedule. Common penalties range from 90 days of dividends on shorter certificates to six or twelve months of dividends on longer ones.

The penalty comes out of your earnings first. If you break a certificate before you’ve earned enough dividends to cover it, the rest comes out of your principal, and you walk away with less than you deposited. One partial offset: the IRS lets you deduct early withdrawal penalties on your federal return, and the deduction reduces adjusted gross income whether or not you itemize.

Variations Worth Knowing About

Standard fixed-rate certificates aren’t the only option. Credit unions often offer variations that add flexibility, usually in exchange for a slightly lower starting rate.

Bump-up certificates let you request a rate increase once during the term if the credit union raises its posted rates after you open the account. The bump isn’t automatic; you have to ask, and it only applies going forward. These usually carry two- or three-year terms.

No-penalty certificates let you withdraw the full balance and earned dividends after a short initial holding period, typically six days, without any penalty. Partial withdrawals generally aren’t allowed, and the starting rate is often lower than a comparable standard certificate.

Add-on certificates accept additional deposits throughout the term, with each new deposit earning the rate you locked in at opening. Not every credit union offers them.

Insurance Is the Same as at a Bank

Credit union share certificates are insured by the National Credit Union Share Insurance Fund, run by the NCUA. Coverage matches what the FDIC provides at banks: up to $250,000 per member, per institution, per ownership category, backed by the full faith and credit of the United States government.⁵ There’s no safety difference between opening a certificate at a credit union and opening a CD at a bank.

The $250,000 limit applies separately to each ownership category, so a single account, a joint account, and a retirement account at the same credit union each carry their own coverage.

You Have to Join First

The one real friction with credit union certificates is membership. Federal law limits each credit union to people who share a common bond, which falls into one of three categories.⁶ Occupational or associational bonds cover people who work for a specific employer or belong to a recognized group. Multiple common bond charters bundle several such groups. Community charters cover anyone who lives, works, worships, or attends school in a defined geographic area.⁷

Community charters are the broadest, and many credit unions have moved to them. If you live or work in the right zip code, you qualify. Immediate family of existing members can usually join too. The NCUA runs a credit union locator at mapping.ncua.gov where you can search by address.

Joining means opening a basic share savings account and keeping a small minimum balance, often between $5 and $25. That balance represents your ownership share in the cooperative.

Watch the Maturity Date

Most share certificates renew automatically at maturity into a new certificate of the same term length at whatever rate the credit union is paying that day. If you do nothing, the rollover happens. Federal rules require the credit union to notify you at least 30 days before maturity for any automatically renewing certificate with a term longer than one month. The credit union can instead send the notice at least 20 days before the end of a grace period, as long as that grace period is at least five days.⁸

The grace period is your window. During it, you can pull the money out penalty-free, move it to a different term, or let the renewal proceed. Miss it and you’re locked into the new term with a fresh set of early withdrawal penalties. Set a calendar reminder a few weeks before any certificate matures. The notice must include the new rate, or tell you the rate hasn’t been set and give you a number to call.⁸
