A money market account sits between a regular savings account and a certificate of deposit

A money market account (MMA) is a savings account that typically pays a higher interest rate than a standard savings account, but comes with a trade-off: you can only withdraw money a limited number of times per month. The bank uses the money you deposit to invest in short-term loans and securities, which is why they can afford to pay you more interest. In exchange, they ask you to leave the money there longer and touch it less often.

The name comes from the "money market" — the financial market where banks and large institutions lend money to each other for short periods. When you open an MMA, your bank is essentially letting you share in the returns from those short-term investments, while they keep the bulk of the profit.

If you have money you want to grow but don't need to access frequently, an MMA can earn you more than a regular savings account at the same bank. However, if you need to withdraw money often, the withdrawal limits can become frustrating and costly.

Key Takeaways

  • Money market accounts pay higher interest rates than regular savings accounts because banks invest your deposits in short-term loans and securities.
  • Most MMAs limit you to six withdrawals per month, and exceeding that limit usually costs a fee or closes the account.
  • You can write checks or use a debit card on some MMAs, but not all — check your bank's specific rules before opening.
  • The interest rate on an MMA changes with market conditions, so your earnings will go up and down over time.
  • An MMA makes sense if you have money set aside for a goal six months or more away and won't need to touch it frequently.

How the withdrawal limit works in practice

Most banks limit you to six withdrawals per month from an MMA. This includes transfers to another account, checks you write, and debit card transactions — essentially any way money leaves the account. The limit exists because the bank's business model depends on keeping your money invested.

If you exceed six withdrawals in a month, the bank will typically charge you a fee (usually $10 to $25 per excess withdrawal). Some banks will close the account if you repeatedly go over the limit. A few banks have removed the withdrawal limit entirely, but they usually pay lower interest rates in return — you lose the main advantage of having an MMA.

The six-withdrawal rule is a federal regulation that applies to most savings products, though banks can be stricter. Before opening an MMA, ask your bank exactly what counts as a withdrawal and what the penalty is for going over.

Interest rates and how they change

The interest rate on an MMA is variable, meaning it changes over time. Your bank sets the rate based on what the Federal Reserve is doing with interest rates nationally. When the Fed raises rates, banks raise the rates they pay on savings products. When the Fed lowers rates, banks lower what they pay you.

This is different from a certificate of deposit (CD), where your rate is locked in for a set period. With an MMA, you might earn 4.5% one month and 4.0% the next month, depending on market conditions. The bank will notify you before the rate changes, but you cannot lock in a higher rate if you want to keep the account flexible.

Because rates change, an MMA is best for money you plan to keep in the account for at least six months to a year. If rates drop sharply, you can always move your money to a CD or another bank's MMA, but you'll want enough time in the account to make the rate advantage worth it.

Access features: checks, debit cards, and transfers

Not all MMAs work the same way. Some banks let you write checks on your MMA, some give you a debit card, some offer both, and some offer neither. You need to know which features your bank provides before you open the account, because this affects how easily you can actually use the money.

If your bank offers check-writing, each check counts as one of your six monthly withdrawals. The same is true for debit card transactions. Some banks let you make unlimited transfers to a linked savings account at the same bank without counting against your withdrawal limit — this is worth asking about, because it gives you a workaround if you need cash quickly.

A few banks offer "sweep" features that automatically move money from your MMA to a linked checking account if you overdraft. This can be helpful if you're worried about accidentally overspending, but it also means money leaves your MMA without you actively choosing it.

Minimum balance requirements and monthly fees

Many banks require you to keep a minimum balance in an MMA to earn the advertised interest rate. This minimum might be $2,500, $10,000, or higher depending on the bank. If your balance drops below the minimum, the bank will either pay you a lower interest rate or charge you a monthly fee.

Some banks also charge a monthly maintenance fee even if you meet the minimum balance. This fee is usually $5 to $15 per month, though many banks waive it if you set up direct deposit or maintain a certain balance. Before opening an account, add up the monthly fee (if any) and compare it to the extra interest you'd earn versus a regular savings account. If the fee is high and the rate advantage is small, the MMA might not be worth it.

Banks also charge fees for exceeding your withdrawal limit, as mentioned earlier. Read the fee schedule carefully — some banks are more aggressive about charging than others.

When an MMA makes sense and when it doesn't

An MMA works well if you have money earmarked for a specific goal — a down payment on a house, a car purchase, a home repair — that you won't need for at least six months. You want the money to grow, but you're not touching it regularly. The higher interest rate will earn you more than a regular savings account, and the withdrawal limit won't bother you because you're not planning frequent withdrawals anyway.

An MMA does not work well if you need to withdraw money frequently, if you have less than $2,500 to deposit, or if you're saving for something less than six months away. In those cases, a regular savings account is simpler and won't penalize you for accessing your money. If you're saving for something more than a year away and won't need the money at all during that time, a CD might earn you more because the rate is locked in higher.

An MMA also doesn't make sense if you're trying to build an emergency fund that you might need to tap quickly. Emergency funds should be in a regular savings account where you can withdraw as much as you want, whenever you want, without fees or limits.

How to compare MMAs across banks

When you're looking at different banks' MMAs, write down four things for each one: the current interest rate, the minimum balance required, any monthly fees, and the withdrawal limit. Then calculate the annual earnings on the amount you plan to deposit, subtract any monthly fees, and compare the net result.

For example, if you're depositing $5,000 and Bank A offers 4.5% with no monthly fee and Bank B offers 4.75% with a $10 monthly fee, Bank A will earn you about $225 per year while Bank B will earn you about $227 per year (after subtracting the $120 annual fee). The difference is small, so other factors like customer service or whether you already bank there might matter more.

Also check whether the bank is FDIC-insured. This means your deposits are protected up to $250,000 if the bank fails. All legitimate banks are FDIC-insured, but it's worth confirming, especially with online banks you've never heard of.

Frequently Asked Questions

Can I withdraw all my money from an MMA whenever I want?

Yes, you can withdraw all your money at any time. The six-withdrawal limit applies to the number of transactions per month, not the total amount. If you want to close the account and take out everything, you can do that in one transaction without penalty. However, if you make more than six separate withdrawals in a month, you'll pay a fee for each one over the limit.

What happens if I go over the withdrawal limit?

Most banks charge a fee of $10 to $25 for each withdrawal over six per month. Some banks will close your account if you repeatedly exceed the limit. A few banks have removed the limit entirely but pay lower interest rates to compensate. Check your bank's specific policy before opening the account.

Is the interest rate may provide to stay the same?

No. The interest rate on an MMA is variable and changes based on what the Federal Reserve does with national interest rates. Your bank will notify you before the rate changes. If rates drop and you're unhappy with the new rate, you can move your money to a different bank or product, but you won't be able to lock in the old higher rate.

How is an MMA different from a CD?

A CD locks in a fixed interest rate for a set period (three months, one year, five years, etc.), while an MMA's rate changes with the market. A CD usually pays more if rates are stable, but an MMA gives you access to your money without a penalty. Choose a CD if you won't need the money for a specific period; choose an MMA if you want flexibility.

Do I need a lot of money to open an MMA?

It depends on the bank. Some banks require a minimum deposit of $2,500 or more to open an MMA, while others have no minimum. Online banks often have lower minimums than brick-and-mortar banks. If you have less than $2,500, a regular savings account will serve you better anyway because you won't meet the minimum balance requirement for the higher interest rate.
