Service CU share-certificate rate sheet

The 1-year share certificate is the headline product, but here's the full term ladder so you can build a real CD ladder:

Term	APY
6-Month	4.30%
1-Year	4.50%
18-Month	4.30%
2-Year	4.25%
3-Year	4.25%
4-Year	4.15%
5-Year	4.10%

APYs as of 2026-06-27. Credit unions reprice less aggressively than online banks, but rates still change — confirm on the Service CU website before funding. Promotional certificates (often on non-standard terms like 11/13/19/25/49 months) may pay higher than the standard rate sheet — ask before opening.

Membership eligibility — who can join Service CU?

Open via American Consumer Council membership (free) — or NH/MA/VT residents and DoD-affiliated.

The workaround: American Consumer Council free membership.

Federally insured credit unions are legally required to limit membership to a defined "field of membership" — but many CUs structure their bylaws to make joining trivially easy via a small donation, a free non-profit membership, or a low-fee sponsor-organization sign-up. The donation/sponsor approach lets you become an Associate Member, which qualifies you for the same accounts and rates as direct-eligibility members. Once you've opened a small share savings account ($5-$50 typical), you can open share certificates online in minutes.

If you can't qualify for Service CU membership, the most accessible national CUs are Alliant (Foster Care to Success $5 donation), Bethpage ($5 savings account, no donation needed), and Connexus ($5 Connexus Association donation).

Pros and cons

How Service CU compares to other credit unions and banks

At the 1-year share-certificate term, here's how Service CU stacks up against directly competing CUs and the highest online banks:

Institution	1-Year APY
Service CU	4.50%
Alliant CU	4.60%
Bethpage FCU	4.50%
Connexus CU	4.55%

Credit unions often beat banks on share-certificate rates by 10-30 basis points at the same term — that's the structural advantage of being non-profit and member-owned. They return profits to members in the form of better rates, lower fees, and lower loan APRs rather than to shareholders. But not every CU does this well. Restricted-membership CUs sometimes coast on rate; open-eligibility CUs (Alliant, Bethpage, Connexus) compete harder because they have to attract members nationally.

When a MYGA beats this share certificate

A Multi-Year Guaranteed Annuity (MYGA) is the insurance-industry equivalent of a CD: a fixed rate locked for a fixed term, principal-protected, backed by the issuing carrier and your state's guaranty association. At the 5-year term, A-rated MYGAs are currently paying around 5.40% — versus Service CU's 4.10%.

Math at $250,000 over 5 years (simple annual compounding):

• Service CU 5-Year @ 4.10%: $305,628 ending balance
• 5-Year MYGA @ 5.40%: $325,194 ending balance
• Difference: $19,566 in favor of the MYGA

MYGAs also defer tax on interest until withdrawal — CDs and share certificates are taxed annually as ordinary income whether you touch the interest or not. For taxable retirement money you don't plan to withdraw for 5+ years, the MYGA almost always wins on math. The trade-off: MYGAs have a fixed surrender schedule (usually 5-10 years), while share certificates have shorter penalty periods. See CD vs MYGA Comparison for the full side-by-side.

NCUA vs FDIC — is the credit union really as safe?

Yes. The National Credit Union Administration (NCUA) insures federally chartered and most state-chartered credit unions up to $250,000 per depositor, per ownership category — the same coverage limit as FDIC. The two agencies use different funds (the National Credit Union Share Insurance Fund vs. the Deposit Insurance Fund), but both are backed by the full faith and credit of the U.S. government. In 50+ years of credit union history, no depositor has ever lost a penny of NCUA-insured funds.

What to verify before opening: confirm Service CU's NCUA-insured status at ncua.gov/research using NCUA charter #01416. If you have more than $250K with one CU, restructure into joint, IRA, or trust ownership categories to expand coverage — each category gets its own $250K limit.

Bottom line on Service CU

Service Credit Union is a legitimate NCUA-insured CU with a rate sheet that's competitive within the CU peer group. The 1-year rate is solid; the 5-year rate is meaningfully behind A-rated MYGAs. If you're a member by direct eligibility (or you've used a $5 workaround), the short-term certificates are a fine place for money you might need in 12-24 months. For 5+ year money, run the MYGA math first.

And remember: most CUs auto-renew at the rate posted on the renewal date — which is often well below the promotional rate you got at opening. Set a calendar reminder 30 days before maturity to compare current rates and decide whether to renew, withdraw, or move the money to a MYGA.

FAQ — Service CU share certificates

What APY does Service CU pay on a 1-year share certificate?

As of 2026-06-27, Service CU pays approximately 4.50% APY on its 1-year share certificate. Rates change frequently; confirm on the Service CU website before opening.

How do I join Service Credit Union?

Service CU opens membership nationally through the American Consumer Council (free to join). Once you're an ACC member, you qualify for Associate Membership at Service CU. NH/MA/VT residents and active/retired military have direct eligibility without ACC.

Is a share certificate at this credit union as safe as a bank CD?

Yes. Federally insured credit unions are insured by the NCUA (National Credit Union Administration) to $250,000 per depositor, per ownership category — the same coverage limit and federal backing as FDIC. The two agencies use different funds, but both are backed by the full faith and credit of the U.S. government.

What is the early withdrawal penalty (EWP) at Service CU?

For terms under 12 months: 90 days div.. For longer terms: 180 days div. (terms >12mo). If accrued dividends are insufficient, the penalty comes out of principal — so the timing of the withdrawal matters.

What is the minimum deposit for a Service CU share certificate?

$500. NCUA insurance covers up to $250,000 per depositor per CU; if you have more than that, split between institutions or use joint-account titling to expand coverage.

Does Service CU auto-renew certificates at maturity?

Yes — Service CU typically auto-renews at the current posted rate for the same term unless you give written instructions during the grace period (usually 7-10 days). Set a calendar reminder; the auto-renewed rate is often below promotional or jumbo-tier rates available at maturity.

Should I consider a MYGA instead of a credit-union CD?

At the 5-year term, A-rated MYGAs are currently paying around 5.40% versus Service CU's ~4.10%. That's a ~1.3% gap on a 5-year contract. MYGAs are tax-deferred (interest isn't taxed until withdrawal); CDs are taxed annually. The trade-offs: MYGAs have a surrender schedule (usually 5-10 years), while CDs let you exit with an interest-only penalty. For taxable retirement money you don't need to touch for 5+ years, the MYGA usually wins on math.
