A common misconception is that money market accounts are the same as money market funds. While their names sound similar, the two work differently. Unlike money market accounts, which carry deposit insurance, money market funds are not deposit accounts or insured by the FDIC or NCUA.

Money market accounts often come with tiered interest rates. This means the highest rates may be reserved for account holders with larger balances, while smaller balances may earn less interest. For instance, a bank might offer 0.10% APY on balances up to $5,000, 0.50% APY on balances of $5,001 to $10,000, and so on. Rates on money market accounts are also variable, meaning they can adjust up or down over time at the bank’s discretion.

Currently, the national average rate for a money market account is 0.66%. However, this is just an average; many banks and credit unions offer rates as high as 3% APY or even more.

Money market accounts may be subject to certain fees and limitations. These include minimum balance fees, monthly maintenance fees, and others. Fees vary widely by financial institution, so be sure to compare fees when selecting an account and choose one that comes with low or no fees.

It’s also important to pay attention to withdrawal limits. While the Federal Reserve essentially in 2020, some banks still impose them. It’s common for banks to charge fees for exceeding six withdrawals within a month.

There are a few benefits and drawbacks to putting your savings in a money market account.

  • Higher interest rates compared to savings accounts: In most cases, money market accounts offer higher interest rates than traditional savings accounts. However, some high-yield savings accounts offer rates comparable to or higher than money market account rates, so it’s a good idea to consider both options.

  • Limited withdrawals: If you plan to use your money market account for everyday banking, this may not be the best fit. While the federal government no longer limits monthly withdrawals on money market and savings accounts at six per month, some banks and credit unions still have these limits in place and may charge you a fee for excessive withdrawals.

  • Lower potential returns compared to riskier investments: If you're looking for a place to put your money for long-term financial needs such as retirement, you'll have a better chance of reaching your savings goals with high-risk market investments.

  • Fees can diminish returns: If your money market account charges a monthly fee, it'll eat into your interest earnings.

As with any type of account, it’s essential to compare your options if you’re interested in a new money market account. Researching the following factors can help you find an account that best meets your needs:

  • Account features: While many money market accounts offer check-writing privileges and debit card access, comparing different account features is still important. For instance, does the bank limit how much you can withdraw or how often you can take money out in a month? Are you able to monitor your account balance via mobile app?

  • Fees: Some banks may charge you fees if your money market account balance drops below a specific amount. Other fees may apply as well. Keep in mind that if a money market account offers a high APY and high fees, it may not be the best choice. Calculate how fees may impact your balance in addition to interest before opening a new account.
