What Is a Money Market Account?
A money market account (MMA) is a type of interest-bearing deposit account offered by banks and credit unions. It combines features of both savings and checking accounts — you earn competitive interest rates while also having limited check-writing and debit card access.
Money market accounts are FDIC-insured (or NCUA-insured at credit unions) up to $250,000, making them one of the safest places to park your cash.
Money Market Account vs. Savings Account
| Feature | Money Market Account | High-Yield Savings |
|---|---|---|
| Interest Rate | 4.00-5.00% APY | 4.00-5.25% APY |
| Check Writing | Yes (limited) | No |
| Debit Card | Often included | Rarely |
| Minimum Balance | $1,000-$25,000 typical | Often $0 |
| Monthly Fees | May apply if below minimum | Usually $0 |
| FDIC Insured | Yes, up to $250,000 | Yes, up to $250,000 |
| Transaction Limits | 6 per month (federal limit removed, but banks may still enforce) | Similar limits |
Money Market Account vs. Money Market Fund
Don't confuse money market accounts with money market funds — they're very different:
Money Market Account: A bank deposit product. FDIC-insured. Fixed or variable APY set by the bank.
Money Market Fund: A type of mutual fund that invests in short-term debt securities. NOT FDIC-insured. Returns fluctuate based on the underlying investments. Available through brokerages like Vanguard, Fidelity, and Schwab.
When a Money Market Account Makes Sense
You Need Check-Writing Access
If you want to earn high interest but occasionally need to write checks — for example, to pay quarterly estimated taxes or make large purchases — an MMA gives you that flexibility.
You're Parking a Large Sum Temporarily
Holding proceeds from a home sale, inheritance, or bonus? An MMA lets you earn competitive interest while maintaining easy access.
You Want Tiered Interest Rates
Many MMAs offer higher rates for larger balances. If you have $25,000+ to deposit, you may earn a premium rate that beats standard savings accounts.
You Want Debit Card Access
Some MMAs come with a debit card, giving you ATM access and the ability to make purchases directly from your high-yield account.
When a High-Yield Savings Account Is Better
You Have a Smaller Balance
If you can't meet the minimum balance requirements (often $1,000-$25,000), a high-yield savings account with no minimum is the better choice.
You Want the Highest Possible Rate
In 2026, the top high-yield savings accounts often edge out MMAs by 0.10-0.25% APY. If maximizing interest is your only goal, a HYSA may win.
You Don't Need Check Writing
If you're simply building an emergency fund or saving for a goal, the check-writing feature of an MMA is unnecessary.
