Money market accounts combine features of both savings and checking
A money market account is neither purely a savings account nor purely a checking account. Instead, it sits between the two, giving you some of the earning power of savings with some of the access of checking. The key difference: you get a higher interest rate than a regular savings account, but you can write checks or make transfers only a limited number of times per month.
The account itself is held at a bank or credit union and is FDIC-insured (or NCUA-insured at credit unions) up to $250,000, just like a regular savings or checking account. Your money is safe and accessible—you are not locking it away or taking on investment risk.
Think of it this way: if a checking account is built for frequent transactions and a savings account is built for holding money, a money market account is built for holding money while still being able to access it quickly when you need to.
Key Takeaways
- Money market accounts pay higher interest rates than savings accounts but restrict how often you can withdraw or transfer money each month.
- You can write checks and make transfers from a money market account, but federal rules limit these transactions to six per month (though this rule is currently unenforced).
- The account is FDIC-insured and your money is not at risk, making it safer than investing in stocks or bonds.
- Money market accounts work best for money you want to earn interest on but might need within a few months, not money you need to access constantly.
How the transaction limits work in practice
Federal Regulation D historically capped withdrawals and transfers from money market accounts at six per month. This rule was suspended during the pandemic and has not been formally reinstated, so many banks no longer enforce it. However, some banks still do—and they can change their policy at any time.
The limit applies to transfers and withdrawals combined, not just one or the other. A transfer to another account counts. A check you write counts. An ATM withdrawal counts. A debit card transaction does not count (if the account comes with a debit card), because debit transactions are treated differently under the regulation.
If you exceed the limit at a bank that enforces it, the bank may charge a fee, close the account, or convert it to a checking account. This is why money market accounts are not suitable for everyday spending—they are meant for money you touch occasionally, not regularly.
Interest rates: why money market accounts pay more
Money market accounts typically pay 4% to 5% annual interest (rates change constantly based on the Federal Reserve's decisions). A regular savings account at the same bank might pay 0.01% to 0.5%. The difference exists because the bank can count on your money staying in the account longer, since you cannot access it as freely.
The tradeoff is explicit: you give up straightforward access, and the bank pays you for that. If you need to withdraw money frequently, you lose the benefit of the higher rate because you will hit the transaction limit and face fees or account closure.
Interest rates vary widely between banks. Online banks and credit unions often pay more than brick-and-mortar banks. Rates also shift with the broader economy—when the Federal Reserve raises rates, money market account rates rise too, usually within a month or two.
When a money market account makes sense
A money market account works well if you have money you want to keep safe and earning interest, but you know you might need it within the next few months to a year. Examples: a down payment fund you are building, an emergency fund you want to earn something on, or money set aside for a planned expense like a car repair or vacation.
It does not work well for money you spend from regularly—groceries, utilities, gas. That is what a checking account is for. It also does not work well for money you will not touch for years—that money might be better in a certificate of deposit (CD), which pays even more interest if you lock it away for a set term.
The account is also useful if you want to separate your spending money from your savings money psychologically. Keeping them in different accounts makes it harder to dip into savings on impulse.
How money market accounts differ from money market funds
Do not confuse a money market account (a bank product) with a money market fund (an investment product). They have similar names but work very differently.
A money market account is a bank account. Your money is FDIC-insured, you earn a fixed interest rate, and you can access it whenever you want (within transaction limits). A money market fund is a mutual fund that invests in short-term debt securities. It is not insured, its value can fluctuate, and it is riskier.
If you see "money market" in a brokerage or investment account, it is almost certainly a fund, not a bank account. If you see it at a bank, it is almost certainly an account. The names are confusing, but the products are fundamentally different.
Comparing money market accounts to savings and checking

| Debit card | Yes, unlimited use | Sometimes, unlimited use | Usually no |
| Checks | Yes, unlimited | Yes, but limited to ~6/month | Usually no |
| Transfers/withdrawals | Unlimited | Limited to ~6/month (varies by bank) | Limited to ~6/month (varies by bank) |
| FDIC insured | Yes, up to $250,000 | Yes, up to $250,000 | Yes, up to $250,000 |
| Best for | Daily spending | Money you need occasionally but want to earn interest on | Money you want to save but rarely touch |
Frequently Asked Questions
Can I use a money market account as my main checking account?
Technically yes, but it is not practical. If you write more than six checks or make more than six transfers per month, you will hit the limit and face fees or account closure. Most people use a checking account for daily spending and a money market account for savings they want to earn interest on.
What happens if I exceed the transaction limit?
It depends on the bank. Some charge a fee per excess transaction. Some convert the account to a checking account. Some close the account. Check your account agreement or call the bank to find out their specific policy, since enforcement varies widely.
Is my money safe in a money market account?
Yes. Money market accounts at banks are FDIC-insured up to $250,000, and accounts at credit unions are NCUA-insured up to $250,000. Your money is protected even if the institution fails. This is different from a money market fund, which is not insured.
Can I get a debit card for a money market account?
Some banks offer debit cards for money market accounts, and some do not. If your account comes with one, debit transactions do not count toward the monthly transfer limit—only withdrawals, transfers, and checks do. Ask your bank whether a debit card is available.
Should I move my emergency fund to a money market account?
If your emergency fund is currently in a checking account earning no interest, moving it to a money market account could earn you 4% or more per year with no additional risk. Just make sure the bank does not enforce the transaction limit strictly, or keep enough in checking for true emergencies and the rest in the money market account.
