How Alliant Certificates (CDs) Work

The interest earned on Alliant Credit Union's certificates is compounded monthly. This means that the interest you earn in one month is added to the principal amount, and subsequent interest calculations are based on the increased balance. At the end of the certificate's term (maturity), you will receive the final interest payment along with the initial deposit.

In the event that you require access to your funds prior to the maturity of your certificate, please be aware that an early withdrawal penalty will be applied. The exact penalty associated with each term can be found in the table provided below.

Alliant Credit Union is federally insured by the National Credit Union Administration (NCUA). This means that your certificate account is protected up to $250,000 per depositor.

How We Rate Certificates of Deposits: Our Methodology

The Smart Investor team has thoroughly examined certificate of deposit (CD) offerings from various banks, considering multiple factors to provide a comprehensive evaluation. Here's how we rated them across four key categories:

  • CD Rates (50%): We meticulously analyzed the interest rates offered by each bank on their certificate of deposit (CD) products. Higher ratings were awarded to banks offering competitive rates that provide maximum returns for customers' investments. Factors such as the yield curve, current market conditions, and consistency of rates were considered to assess the attractiveness of each bank's CD rates.

  • CD Features (30%): This category evaluated the features associated with each bank's certificate of deposit offerings. Factors considered include the variety of terms available, early withdrawal penalties, minimum deposit requirements, and any additional features or benefits. Higher ratings were given to banks offering a diverse range of CD terms, reasonable early withdrawal fees, and flexible options to meet customers' investment needs.

  • Customer Experience (10%): A positive customer experience is paramount, even when investing in CDs. We assessed each bank's performance in this area, considering factors such as the ease of opening a CD account, the responsiveness of customer service, and overall user satisfaction. Higher ratings were assigned to banks with efficient account opening processes, helpful customer support, and a track record of satisfying customers.

  • Bank Reputation (10%): The reputation of a bank is a critical consideration when investing in CDs. We evaluated each bank's reputation based on factors such as financial stability, regulatory compliance, and public perception. Higher ratings were given to banks with a solid reputation for reliability and trustworthiness, ensuring customers' investments are safe and secure.

By considering these categories and assigning appropriate weights to each, our review aims to provide valuable insights to help individuals make informed decisions when investing in certificate of deposits.
