What is a Money Market Account?
A money market account (MMA) is a savings-style bank account that typically earns more interest than a standard savings account while offering FDIC insurance and some access to funds through checks or a debit card.
A money market account (MMA) is a deposit account offered by banks and credit unions that typically earns a higher interest rate than a standard savings account. It's insured by the FDIC (at banks) or NCUA (at credit unions) up to $250,000, making it one of the safest places to park cash — while still earning a meaningful return.
MMAs often come with limited check-writing privileges or a debit card, giving you more flexibility than a typical savings account. However, they often require higher minimum balances and may cap the number of monthly withdrawals.
Money Market Account vs. Savings Account
| Money Market Account | High-Yield Savings Account | |
|---|---|---|
| Interest rate | Generally competitive | Often comparable or higher at online banks |
| Check-writing | Sometimes available | Usually not |
| Debit card | Sometimes available | Rarely |
| Minimum balance | Often $1,000–$10,000 | Often $0 at online banks |
| FDIC insured | Yes | Yes |
| Withdrawal limits | Federal limit removed (but bank limits may apply) | Same |
Note: Prior to 2020, federal Regulation D capped savings and money market accounts at 6 withdrawals per month. That cap was officially eliminated, but many banks still enforce their own limits.
Money Market Account vs. Money Market Fund
This is a common source of confusion:
| Money Market Account | Money Market Fund | |
|---|---|---|
| Offered by | Banks and credit unions | Investment companies (Vanguard, Fidelity, etc.) |
| FDIC insured | Yes | No |
| Risk level | Very low (insured) | Very low (but not zero) |
| Typical yield | Variable, set by bank | Tied to short-term rates |
| Where it lives | Your bank | Your brokerage account |
A money market fund is a mutual fund that invests in short-term, low-risk debt instruments. It's not FDIC insured, but it has historically been extremely safe. During the 2008 financial crisis, one money market fund "broke the buck" (fell below $1.00 per share) — a rare event that rattled markets.
When a Money Market Account Makes Sense
MMAs are best suited for:
- Emergency fund storage — FDIC-insured, accessible, and earning a reasonable rate while your cash sits available
- Short-term savings goals — Money you'll need in 1–3 years that shouldn't be invested in the market
- Parking large cash amounts — If you have a significant sum to hold temporarily (waiting to invest, before a home purchase, etc.), an MMA keeps it safe and earning interest
For long-term money — retirement savings, money you won't need for 5+ years — keeping cash in an MMA is usually a poor choice because the returns won't keep pace with inflation over time. That money is better deployed in a diversified investment portfolio.
What to Look For in a Money Market Account
- APY (Annual Percentage Yield) — The higher, the better. Online banks consistently offer higher rates than traditional brick-and-mortar banks.
- Minimum balance — Some accounts require $5,000–$10,000 to earn the top rate or to avoid monthly fees
- Monthly fees — Watch for fees that can offset interest earnings on smaller balances
- Access — If you might need quick access to the money, check whether the account comes with a debit card or check-writing privileges
High-yield savings accounts at online banks often offer rates comparable to or exceeding money market accounts with fewer restrictions, so it's worth comparing both options before deciding where to keep your cash reserves.
