A money market savings account is a hybrid account that combines features of checking and savings accounts, typically paying higher interest than a regular savings account in exchange for maintaining a minimum balance
Money market accounts sit between traditional savings and money market funds. Your bank holds the money, insures it under FDIC protection up to $250,000, and pays you interest based on current market rates. The catch: you usually need to keep a minimum balance (often $2,500 to $25,000, depending on the bank), and you get a limited number of withdrawals per month before fees kick in.
The interest rate changes with the market. When the Federal Reserve raises rates, your money market account rate typically rises within weeks. When rates fall, so does your payout. This is different from a fixed-rate CD, where your rate is locked in for the full term.
Key Takeaways
- Money market accounts pay interest that moves with market rates, usually higher than regular savings but lower than CDs or money market funds.
- You must maintain a minimum balance to avoid monthly fees, and that minimum varies by bank from $1,000 to $25,000.
- Most accounts limit you to six withdrawals per month; exceeding that triggers a fee or account closure at some banks.
- Your money is FDIC-insured up to $250,000, so your principal is protected even if the bank fails.
How the interest rate works
The rate on a money market account is not fixed. Banks set their rates based on what the Federal Reserve does and what competing banks are offering. When you open an account, you see the current rate—but that rate can change monthly, weekly, or even daily depending on the bank's policy.
You earn interest on your full balance every day, and it compounds (usually daily or monthly). If you keep $10,000 in an account paying 4.50% APY, you earn roughly $450 per year, paid out in small increments. The exact amount depends on how often the bank compounds interest and whether your balance stays steady.
Some banks offer tiered rates: a higher rate if you maintain $25,000, a lower rate if you keep $10,000. Read the fine print to see what rate applies to your balance level.
Minimum balance requirements and fees
Nearly every money market account requires you to keep a minimum balance. If your balance drops below that threshold, you pay a monthly fee—typically $10 to $25. Some banks waive the fee if you maintain the minimum for just one day of the month; others require it for the entire month.
The minimum itself varies widely. Online banks often require $2,500 to $10,000. Traditional banks may ask for $25,000 or more. A few banks have no minimum, but they usually pay lower rates to compensate.
Beyond the minimum, watch for withdrawal limits. Federal rules no longer cap withdrawals, but individual banks often limit you to six per month. Going over that limit costs $10 to $35 per excess withdrawal, or the bank may close your account.
When a money market account makes sense
A money market account works best if you have $5,000 to $50,000 sitting in savings and you want better interest than a regular savings account without locking the money away. You keep access to your funds (within the withdrawal limit) while earning a competitive rate.
It is less useful if you need to make frequent withdrawals—more than six per month—because fees add up fast. It is also not ideal if you have less than the minimum balance, since you will pay fees that eat into any interest you earn.
If you have a very large sum ($100,000+), a money market fund (not an account) may pay more, though it lacks FDIC insurance. If you want to lock in a rate for a specific time, a CD is more predictable.
Money market accounts versus other savings options
| Account Type | Interest Rate | Minimum Balance | Withdrawal Limits | FDIC Insured |
|---|---|---|---|---|
| Regular Savings Account | 0.01% to 0.50% APY | $0 to $500 | None | Yes, up to $250,000 |
| Money Market Account | 4.00% to 5.35% APY (varies by bank) | $1,000 to $25,000 | Usually 6 per month | Yes, up to $250,000 |
| Certificate of Deposit (CD) | 4.50% to 5.50% APY (locked in) | $500 to $2,500 | None until maturity | Yes, up to $250,000 |
| Money Market Fund | 5.00% to 5.40% APY | $1,000 to $3,000 | None | No—not FDIC insured |
A regular savings account is simpler if you have a small balance or make frequent withdrawals, but the interest is negligible. A CD locks your rate but freezes your money for a set term (3 months to 5 years). A money market fund pays similarly to a money market account but carries investment risk and no insurance.
How to open a money market account
Most banks and credit unions offer money market accounts online or in person. You will need a government ID, your Social Security number, and an initial deposit to meet the minimum. Some banks let you open with less and waive the minimum fee for the first month while you build up the balance.
Compare rates across banks before you choose. A difference of 0.50% APY sounds small, but on $25,000 it means $125 per year. Online banks typically pay more than brick-and-mortar banks because they have lower overhead. Credit unions sometimes offer competitive rates to members.
Once your account is open, you can deposit money by transfer, direct deposit, or check. You withdraw via debit card, check, or electronic transfer—but remember the monthly withdrawal limit.
What happens if you fall below the minimum
If your balance drops below the required minimum, the bank charges a monthly maintenance fee. This fee is deducted from your account, which can push you further below the minimum and trigger another fee the following month.
Some banks offer a grace period: if you dip below the minimum for a few days, no fee. Others charge immediately. A few will close your account if the balance stays low for several months.
If you know you will need to withdraw a large sum, move the money to a regular savings account first to avoid the fee. Or ask your bank if they offer a waiver for temporary dips.
Frequently Asked Questions
Can I use a debit card to withdraw from a money market account?
Most money market accounts come with a debit card, but using it counts toward your monthly withdrawal limit. Some banks count debit card purchases and ATM withdrawals separately; others count them together. Check your account agreement to see how your bank tracks this.
What if interest rates drop after I open my account?
Your rate will drop too, usually within a few weeks. Banks adjust rates based on market conditions, not on how long you have had the account. If rates fall significantly, you may want to move your money to a CD to lock in a higher rate before it drops further.
Is my money safe in a money market account?
Yes, up to $250,000 per account holder per bank. FDIC insurance protects your principal if the bank fails. The interest rate can change, but your deposits are may provide. If you have more than $250,000, open accounts at different banks to stay fully insured.
Can I transfer money between my money market account and checking account without hitting the withdrawal limit?
It depends on the bank. Some banks count transfers as withdrawals; others do not. Federal rules no longer restrict transfers, but individual banks set their own policies. Ask your bank directly before you open the account.
What is the difference between a money market account and a money market fund?
A money market account is a bank product insured by the FDIC. A money market fund is an investment product that is not insured but often pays slightly more. Money market funds carry a small risk of losing value; bank accounts do not. Choose an account if you want safety; choose a fund if you want maximum yield and can accept risk.
