High-yield savings accounts vs. CDs vs. money market funds

When it comes to managing your cash, having the right tools in your financial tool kit can make all the difference. High-yield savings accounts, certificates of deposit (CDs), and money market funds are 3 popular options for short-term savings, each of which offers unique benefits. Understanding the differences between these savings products can help you make informed decisions that align with your financial goals, whether you're looking for the highest potential return or the greatest liquidity.
What is a high-yield savings account?
A high-yield savings account works very much like your other bank or credit union accounts, but they typically offer a higher interest rate compared with a traditional savings account. This makes it a great option for those looking to potentially earn more interest on their cash while keeping it accessible.
High-yield savings accounts are eligible for Federal Deposit Insurance Corporation (FDIC) insurance, which makes them a safe place to keep your money. They also typically don't have withdrawal penalties, so you can access your money whenever you need it. Some high-yield savings accounts limit the number of transactions you can make in a given period, so it's a good idea to check the details with the offering bank or institution.
If you're looking for higher returns without locking in your money, a high-yield savings account could be a smart choice.
How high-yield savings accounts work
High-yield savings accounts typically offer features like next-day bank transfers, checkwriting, and compatibility with apps like Venmo and PayPal, making them convenient and highly accessible.
Another key benefit is the compound interest you'll generate on your savings. This means that the interest you earn is added to your principal, and you start earning interest on that interest. Over time, this can significantly boost your savings.
In addition to convenience and earning potential, high-yield savings accounts are also insured by the FDIC or National Credit Union Administration (NCUA) for up to $250,000 per depositor, per bank or credit union. This provides a high level of security, ensuring that your money is protected against institutional failures.
While high-yield savings accounts are a great option for some, it's also worth considering cash management accounts, such as Vanguard Cash Plus. Here's how they differ:
- Cash management accounts. These accounts often have a combination of features, including checkwriting and the ability to link to other investment accounts.
- Cash management accounts can provide competitive returns by investing your money in a mix of short-term, low-risk investments.
- High-yield savings accounts. These accounts focus primarily on keeping your money accessible and offering a higher interest rate than a traditional checking account.
Both options have their merits, and the best choice depends on your specific needs and financial goals. Cash management accounts are generally offered by brokerages like Vanguard Brokerage, and they often have higher interest rates than traditional bank savings accounts. If you value a comprehensive financial management solution, a cash management account might be the way to go. For example, you can keep your Vanguard Cash Plus Account linked to your Vanguard Brokerage Account, so you can view your short-term and long-term investments in one place.1
Pros and cons of high-yield savings accounts
What is a certificate of deposit?
A certificate of deposit (CD) is a type of savings account that holds your money for a fixed term ranging from a few months to several years. Long-term CDs generally offer higher fixed interest rates than short-term CDs. Once the term ends, you can withdraw your money plus the interest earned or roll it over into another CD.
CDs are a low-risk way to earn more on your savings, especially if you don't need immediate access to your money.
How CDs work
A CD has a specific maturity period, which is the length of time you agree to keep your money in the account. During this period, you’ll earn interest at a fixed rate. If you withdraw your funds before the maturity date, you'll typically pay an early withdrawal penalty. The penalty can vary, but it often amounts to a few months' worth of interest.
When it comes to penalties, there's a difference between CDs bought from banks and those bought from brokers like Vanguard Brokerage. Bank CDs usually have penalties for early withdrawal, while brokered CDs might offer more flexibility. For example, brokered CDs can sometimes be sold on the secondary market, though you might have to sell at a loss if interest rates have risen.
Always check the terms and conditions to understand the specific rules and penalties associated with your CDs.
Pros and cons of CDs
What is a money market fund?
A money market fund is a type of mutual fund that's designed to offer a low-risk, stable investment option for money you may need to access in the short term, such as emergency funds or savings for a short-term goal.
When comparing a money market fund with a savings account, keep in mind that money market funds generally offer higher interest rates but come with a bit more risk, as they aren't insured by the FDIC. Money market funds can potentially lose value, though this is very rare.
When held in a brokerage account, money market funds are covered by Securities Investor Protection Corporation (SIPC) insurance, which protects up to $500,000 in case the fund fails. Money market funds are also regulated by the Securities and Exchange Commission (SEC). The SEC requires money market funds to maintain certain levels of daily and weekly liquidity. The SEC has this requirement to help maintain fund stability and safety.
While money market accounts and money market funds sound similar and invest in similar assets, there are some important differences. Money market accounts are bank accounts, while money market funds are offered by investment firms. They also differ in terms of insurance coverage, fees, withdrawal restrictions, yields, minimums, and features.
How money market funds work
Money market funds are investment vehicles operated by financial institutions that pool money from many investors to purchase low-risk, short-term debt securities, such as Treasury bills, municipal debt, or corporate bonds.
