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 0.65% 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.
