What Is a Money Market Account (MMA)?

Let me explain what a money market account, or MMA, really is. It's a type of bank account that earns interest and blends features from both savings and checking accounts. You can find them at credit unions and banks, and they often come with checks and a debit card, but expect limits on how many times you can withdraw money each month.

Traditionally, MMAs have offered higher annual percentage yields, or APYs, than standard savings accounts, though these days the top high-yield savings accounts can match or even surpass the rates of the best MMAs. What sets MMAs apart is the easier access to your funds compared to plain savings accounts.

Key Takeaways

To sum it up directly, money market accounts have elements of both savings and checking accounts. They might pay higher interest than regular savings and make transactions simpler with checks and debit cards. I recommend them for short-term financial goals, not long-term planning like retirement. Similar options include high-yield savings accounts and certificates of deposit.

How Money Market Accounts (MMAs) Work

With an MMA, you can make unlimited deposits each month, but withdrawals, especially convenient ones like overdraft transfers, phone transfers, or automatic ones, are typically limited to about six per month. Remember, how often the interest compounds—whether yearly, monthly, or daily—can make a big difference in your returns, particularly with a large balance. Banks vary on this; some compound daily, others monthly.

Since MMAs include check-writing and debit card options, you can pay people, make purchases, or use ATMs easily, but those count toward your monthly limits.

Pros and Cons of Money Market Accounts

Your cash in an MMA is accessible and insured by the FDIC or NCUA up to $250,000. Drawbacks include fees and variable rates. Let me break this down further.

On the pros side, MMAs often have higher APYs than standard savings. You get check-writing privileges for things like rent or donations, debit cards for convenience without transferring to checking, and that insurance protection up to $250,000 per depositor, or $500,000 for joint accounts.

For the cons, rates can fluctuate since they're variable, unlike fixed-rate CDs. Transaction limits still apply at many banks, even after federal rules eased in 2020. You might need to maintain a minimum balance, often around $2,500, and fees can hit if you drop below that or exceed withdrawals.

Money Market Accounts (MMAs) vs. Other Accounts

You have alternatives like savings accounts, checking accounts, CDs, and money market funds. Let me compare them directly.

Savings accounts average lower APYs at 0.41% compared to MMAs at 0.64%, but top MMAs can exceed 5%. High-yield savings are similar to MMAs but without checks or debit cards, sometimes with even higher rates.

Checking accounts allow unlimited transactions with checks and debit cards but low APYs around 0.07%. High-yield checking can match MMA rates but might require specific activity to avoid fees.

Rewards checking offer bonuses like cashback but come with rules to qualify. CDs lock your money for a fixed term with higher fixed rates, but early withdrawals incur penalties.

Money market mutual funds are investments, not deposit accounts, with higher returns but no federal insurance.

The Bottom Line

If you're looking for better returns than most savings accounts or a flexible option for short-term goals like vacations or emergency funds, an MMA fits well. It's more accessible than other savings vehicles. For long-term goals like retirement, though, you're better off with IRAs or 401(k)s that offer higher potential returns.
