Capital One CD Vs Ally CD: How They Work?

The Capital One 360 CD option stands out as a flexible choice for savers, as there is no minimum deposit requirement, making it accessible to individuals who are just starting to build their savings. Interest is calculated daily and compounded, with payments made monthly throughout the term of the CD.

However, if you need to withdraw money before the term is up, you will be charged an early withdrawal penalty. The penalty can range from three months of earned interest to six months of earned interest, depending on the terms of the agreement.

Besides the regular options, Ally Bank also offers a unique “Raise Your Rate” CD option that comes in either a two-year or four-year term.

While the starting rate for this CD is lower than the average rate on the High Yield CD, the benefit is that customers have the option to increase their rate once for the two-year term or twice for the four-year term if the Ally CD rate goes up during the term.

When It Comes to No Penalty CD - Ally Wins

Ally Bank also offers a no-penalty CD option, which boasts a higher current rate than the shorter-term Ally High Yield CDs and is considered one of the best no-penalty CD rates available.

One of the benefits of this CD is that customers are not locked into the maturity of the CD, which provides more flexibility for those who may need to access their funds before the end of the 11-month term.

Although there are no early withdrawal penalties, a withdrawal cannot be made until six days after the account is opened.

How We Compare CDs: Methodology

In our comprehensive certificate of deposit (CD) comparison, The Smart Investor team meticulously evaluated various CDs across four key categories to assist you in selecting the most suitable option for your savings goals.

  • CD Rates: We thoroughly examined the interest rates offered by each CD, considering their competitiveness in the market. Higher rates typically translate to greater returns on your investment over the CD's term. Additionally, we scrutinized any special promotional rates or conditions that might affect the overall value of the CD.
  • CD Features: This category focuses on the unique features and terms associated with each CD. We assessed factors such as minimum deposit requirements, early withdrawal penalties, and the availability of flexible terms. Additionally, we considered any additional perks like interest compounding frequency or options for automatic renewal.
  • Customer Experience: A positive customer experience is crucial in banking, and we evaluated each institution's performance in this regard. We looked into aspects such as the ease of opening a CD, the quality of customer service, and the availability of support channels. Reviews from reputable sources such as Trustpilot and JD Power rankings were also considered to gauge overall user satisfaction.
  • Bank Reputation: The reputation of the bank is a significant factor in the decision-making process. We examined the bank's financial stability, regulatory compliance, and public perception to assess its overall trustworthiness and reliability as a CD provider.
