A money market account is a hybrid savings product that combines features of a checking account and a savings account
A money market account (MMA) lets you earn interest on your balance while keeping your money accessible. Unlike a regular savings account, it typically comes with a debit card or checkbook so you can withdraw funds without visiting a branch. The trade-off is that the interest rate fluctuates based on market conditions, and most banks limit how many withdrawals you can make each month.
The account sits between a traditional savings account and a money market fund. You get FDIC insurance protection (up to $250,000 per depositor at most banks), which you would not have with a mutual fund. The interest rate moves with the broader economy rather than staying fixed, so what you earn changes over time.
Key Takeaways
- Money market accounts earn variable interest rates that change based on market conditions and your bank's decisions, not a fixed rate locked in at opening.
- Most banks limit you to six withdrawals per month (or per statement cycle), and some charge fees if you exceed that limit.
- You get FDIC insurance coverage up to $250,000, which protects your balance if the bank fails.
- The interest rate is usually higher than a regular savings account but lower than a CD, making it useful for money you need to access but want to earn something on.
How the interest rate works on an MMA
The rate your bank pays you changes whenever the bank decides to change it. Banks typically raise rates when the Federal Reserve raises its benchmark rate, and lower them when the Fed cuts rates. You will not see your rate locked in for a term the way you would with a certificate of deposit (CD).
The rate also depends on your balance. Many banks offer tiered rates, meaning you earn a higher percentage if you keep a larger amount in the account. A bank might pay 0.50% on balances under $10,000 and 1.25% on balances of $100,000 or more. Check your bank's rate sheet to see whether your balance qualifies for a higher tier.
Because rates change frequently, an MMA that pays well today may not pay well in six months. This makes it less predictable than a CD but more flexible if you think rates might rise and you want to benefit without being locked in.
Withdrawal limits and how they affect you
Federal rules allow banks to limit you to six withdrawals per month from a money market account. This includes transfers to another account, checks you write, and debit card withdrawals. In-person withdrawals at a branch or ATM usually do not count toward the limit.
If you exceed the limit, your bank may charge a fee (typically $10 to $25 per excess withdrawal) or close the account. Some banks waive the limit during certain periods or for customers who maintain a high balance, so check your account agreement. If you need to make frequent withdrawals, a regular savings account or checking account may suit you better.
The limit exists because money market accounts are designed to hold money you access occasionally, not money you move around constantly. If you are using it as a checking account, you will run into the restriction quickly.
Comparing MMAs to savings accounts and CDs
| Feature | Money Market Account | Savings Account | Certificate of Deposit (CD) |
|---|---|---|---|
| Interest rate | Variable, changes with market | Variable, usually lower than MMA | Fixed for the term |
| Access to funds | Debit card or checks, limited withdrawals | Limited withdrawals, no debit card | Locked until maturity; early withdrawal penalty |
| Monthly withdrawal limit | Usually 6 per month | Usually 6 per month | No limit (but penalty if you withdraw early) |
| FDIC insurance | Yes, up to $250,000 | Yes, up to $250,000 | Yes, up to $250,000 |
| Best for | Money you need occasional access to and want to earn interest on | Emergency funds or money you rarely touch | Money you will not need for a set period |
A savings account is simpler but usually pays less interest. A CD pays more interest but locks your money away and charges you if you need it early. An MMA splits the difference: better rates than savings, but you can still access your money without a penalty.
Minimum balance requirements and fees
Most banks require a minimum opening balance to start an MMA, often between $1,000 and $25,000. Some banks waive the minimum if you set up automatic deposits or maintain a linked checking account. Check the specific bank's requirements before you open an account.
Beyond the withdrawal limit fee, MMAs may charge a monthly maintenance fee (typically $5 to $15) if your balance falls below the minimum. Some banks waive this fee if you maintain direct deposit or keep a certain balance. A few online banks offer no-fee MMAs with no minimum balance, though their rates may vary.
Read the fee schedule carefully. A high interest rate means little if fees eat into your earnings, especially on smaller balances.
When an MMA makes sense for your savings goals
An MMA works well if you have money you want to earn interest on but might need within the next year or two. Examples include a down payment fund you are building, a buffer for a job transition, or money set aside for a planned purchase. The interest rate is usually better than a savings account, and you can access the funds without penalty.
An MMA is less useful if you need to make frequent transfers (you will hit the withdrawal limit), if you have a very small balance (fees will outpace interest), or if you are saving for a specific date more than a few years away (a CD would lock in a better rate). It is also not the right place for money you might need in an emergency within the next few weeks, because the rate may not be high enough to justify the withdrawal restrictions.
Frequently Asked Questions
Can I use a money market account like a checking account?
You can write checks and use a debit card on most MMAs, but you are limited to six withdrawals per month. If you need to make more than six transactions, you will face fees or account closure. For frequent spending, use a checking account instead.
What happens if I withdraw more than the allowed limit?
Your bank will charge a fee for each excess withdrawal, usually $10 to $25. If you repeatedly exceed the limit, the bank may close the account or convert it to a different type of account. Check your account agreement for your bank's specific policy.
Is my money safe in a money market account?
Yes. MMAs are FDIC-insured up to $250,000 per depositor per bank. This means if the bank fails, the government guarantees your balance. The insurance does not cover losses from market downturns, but your principal is protected.
Will my interest rate stay the same?
No. Money market account rates change based on market conditions and your bank's decisions. You might earn 1.50% one month and 1.25% the next. This is different from a CD, where the rate is locked in for the entire term.
How much money should I keep in a money market account?
That depends on your goals and the minimum balance requirement. If you are saving for something specific in the next one to three years, an amount between $5,000 and $50,000 is typical. Smaller amounts may not earn enough to offset fees; larger amounts might be better placed in a CD if you do not need access.
