Expert review

Alliant Credit Union competes with many online banks. It offers competitive CD rates, no monthly fees and round-the-clock customer service. It only has two branch locations in Chicago, so it’s a better choice for those who are comfortable with Internet banking.

But you’ll need an Alliant membership and a $1,000 minimum deposit to qualify.

Benefits of Alliant Credit Union CDs

Alliant Credit Union CDs are NCUA-insured up to $250,000 and come with these benefits:
  • Flexible terms. Alliant offers CDs with one to five-year terms.
  • Attractive rates. Earn 0.55% to 0.8% APY depending on the term length.
  • 24/7 phone support. Customer service is available daily by phone.
  • No fees. You won’t pay a fee to maintain your account, which means you keep more money in your pocket.

What to watch out for

Alliant Credit Union CDs offer many attractive perks, but watch out for these potential drawbacks:
  • High minimum deposits. You’ll need at least $1,000 to open an account.
  • No short-term options. The shortest CD term Alliant offers is 12 months.
  • Limited branches. Alliant only has two branch locations in Chicago, so it’s not ideal if you want to bank in person.
  • Must be a member. You must have an active Alliant membership before you can open a CD.

If you want a CD with a minimum lower deposit, you’ll want to keep looking. As always, compare your options when choosing a CD.

How do I cash in a CD?

Once your CD matures, you have three options:

  1. Renew it for another term
  2. Roll it over to a different term
  3. Transfer it to another bank account

If you renew your CD, you have a 10-day grace period after maturity where you can add or withdraw money without penalty.

If you do nothing, your CD will either automatically renew or transfer to another account depending on which option you selected during the application process.

What other savings products does Alliant Credit Union offer?

Alliant Credit Union has three other savings account options:

  • High-Rate Savings account. Offers no monthly fee and 0.55% APY, but you must keep a $100 minimum balance to earn interest.
  • Supplemental Savings account. If you have multiple savings goals, you can open up to 19 additional accounts featuring all the same perks as the High-Rate Savings account.
  • Kids Savings account. Kids 12 and younger can open up this free account with a parent and earn 0.55% APY.

CDs ratings

★★★★★ — Excellent

★★★★★ — Good

★★★★★ — Average

★★★★★ — Subpar

★★★★★ — Poor

We rate CDs and share certificates on a scale ranging from one to five stars based on what matters most to you. We consider two factors equally when rating CDs: minimum deposits and annual percentage yields (APYs) relative to term length. If a bank requires a different minimum opening deposit depending on the chosen term, we rate the CD based on the average minimum deposit across all terms. And although some institutions offer CDs with terms ranging from one week to 20 years, we only consider term lengths the FDIC uses in its monthly updates on national rates.
