CDs vs. MMAs vs. Savings Accounts


When it comes to saving money, there are several options available to individuals looking to grow their wealth. Three popular choices are Certificates of Deposit (CDs), Money Market Accounts (MMAs), and traditional Savings Accounts. Each of these options has its own unique features and benefits, making it important for savers to understand the differences between them. In this article, we will explore the characteristics of CDs, MMAs, and Savings Accounts, and discuss the advantages and disadvantages of each.

Certificates of Deposit (CDs)

Certificates of Deposit, commonly referred to as CDs, are a type of time deposit offered by banks and credit unions. They are known for their fixed interest rates and predetermined maturity dates. Here are some key features of CDs:

  • Fixed interest rates: CDs offer a fixed interest rate for a specific term, which can range from a few months to several years. This means that the interest rate remains constant throughout the duration of the CD.
  • Maturity dates: CDs have a predetermined maturity date, which is the date when the CD reaches its full term. At this point, the saver can choose to withdraw the funds or roll them over into a new CD.
  • Penalties for early withdrawal: If a saver decides to withdraw funds from a CD before its maturity date, they may be subject to penalties, such as forfeiting a portion of the interest earned.

CDs are often considered a low-risk investment option, as they are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor. They are a popular choice for individuals who have a specific savings goal in mind and do not need immediate access to their funds.

Money Market Accounts (MMAs)

Money Market Accounts, or MMAs, are a type of savings account that typically offers higher interest rates compared to traditional savings accounts. Here are some key features of MMAs:

  • Higher interest rates: MMAs generally offer higher interest rates compared to regular savings accounts. This is because the funds deposited in MMAs are often used by banks to invest in short-term, low-risk securities.
  • Limited check-writing ability: Unlike traditional savings accounts, MMAs often come with limited check-writing abilities, allowing savers to access their funds more easily.
  • Minimum balance requirements: Many MMAs require a minimum balance to be maintained in order to avoid monthly fees. These requirements can vary depending on the financial institution.

MMAs are a good option for individuals who want to earn a higher interest rate on their savings while still maintaining some level of liquidity. They are suitable for savers who may need to access their funds more frequently or want the flexibility of writing checks.

Savings Accounts

Savings accounts are the most common and widely used type of deposit account offered by banks and credit unions. Here are some key features of savings accounts:

  • Low interest rates: Savings accounts typically offer lower interest rates compared to CDs and MMAs. However, they are still a safe and reliable way to save money.
  • Liquidity: Unlike CDs, savings accounts provide easy access to funds, allowing savers to withdraw money whenever needed without penalties.
  • No minimum balance requirements: While some savings accounts may have minimum balance requirements, many financial institutions offer accounts with no minimum balance requirements.

Savings accounts are a suitable option for individuals who want to save money while maintaining easy access to their funds. They are ideal for emergency funds or short-term savings goals.

Comparing CDs, MMAs, and Savings Accounts

Now that we have explored the features of CDs, MMAs, and savings accounts, let's compare them based on a few key factors:

Interest Rates

CDs generally offer higher interest rates compared to MMAs and savings accounts. The longer the term of the CD, the higher the interest rate tends to be. MMAs typically offer higher interest rates compared to savings accounts, but they may require a higher minimum balance to earn the higher rate.


Savings accounts provide the highest level of liquidity, as funds can be easily withdrawn without penalties. MMAs also offer a certain level of liquidity, although they may have limitations on the number of withdrawals or checks that can be written per month. CDs have the lowest level of liquidity, as withdrawing funds before the maturity date can result in penalties.

Risk and Safety

All three options, CDs, MMAs, and savings accounts, are considered safe investments. CDs and savings accounts are insured by the FDIC up to $250,000 per depositor, while MMAs are often insured by the National Credit Union Administration (NCUA) for credit union accounts. However, it's important to note that investments in MMAs may involve some level of risk, as the funds are often used for short-term investments.

Case Study: John's Saving Strategy

To better understand how CDs, MMAs, and savings accounts can be utilized in a saving strategy, let's consider the case of John, a 35-year-old individual with a stable income and a goal to save for a down payment on a house within the next five years.

John decides to allocate his savings into three different accounts:

  • A 5-year CD with a fixed interest rate of 2.5% to ensure a higher return on a portion of his savings.
  • An MMA with a higher interest rate of 1.75% to earn more on his emergency fund, which he may need to access occasionally.
  • A traditional savings account with a lower interest rate of 1% for his short-term savings goals and regular expenses.

By diversifying his savings across these three accounts, John can maximize his returns while maintaining liquidity and flexibility. The CD provides a higher return over a longer period, the MMA offers a competitive interest rate with limited check-writing abilities, and the savings account ensures easy access to funds for his short-term needs.


When it comes to choosing between CDs, MMAs, and savings accounts, there is no one-size-fits-all solution. Each option has its own advantages and disadvantages, and the best choice depends on an individual's financial goals and circumstances.

CDs are ideal for individuals with a specific savings goal in mind and who can afford to lock their funds away for a fixed period. MMAs offer higher interest rates and some level of liquidity, making them suitable for savers who want to earn more while maintaining access to their funds. Savings accounts provide easy access to funds and are suitable for short-term savings goals or emergency funds.

By understanding the features and differences between CDs, MMAs, and savings accounts, individuals can make informed decisions about how to best grow their wealth and achieve their financial goals.
