How to open a money market account
Opening a money market account takes between 10 minutes and a few days, depending on whether you bank online or in person. You will need a government-issued ID, your Social Security number, and proof of your current address — usually a recent utility bill or bank statement. Most banks and credit unions let you start the process on their website or app, fund the account when ready with a transfer from another bank account you own, and begin earning interest within a day or two.
The actual steps are straightforward: choose where to open the account, gather your documents, complete the process (which asks for your name, address, employment, and income), fund it, and set your PIN or online password. Some institutions require a minimum deposit to open — this ranges from $0 to several thousand dollars depending on the bank — so check that before you start.
Key Takeaways
- You will need a government ID, Social Security number, and proof of address such as a utility bill or recent bank statement.
- Online applications usually take 10 to 15 minutes and let you fund the account the same day by transferring money from another bank account you own.
- Different banks have different minimum deposit requirements, ranging from zero dollars to several thousand, so compare before you choose.
- Once your account is open, you can usually make up to six withdrawals per month before the bank charges a fee or restricts your account.
- Money market accounts earn interest, but the rate changes monthly or quarterly, so your earnings will vary over time.
Choosing between online banks and local banks
Online banks typically have no minimum deposit requirement and higher interest rates, but you cannot walk into a branch or speak to someone in person. Local banks and credit unions usually require a minimum deposit of $500 to $2,500, offer lower interest rates, but give you a physical location and a person to talk to if something goes wrong.
If you are new to banking or uncomfortable with online-only accounts, a local bank or credit union is often the better choice even if the interest rate is lower. You can ask questions face-to-face, and if you need to deposit cash, you can do it at a branch. If you are comfortable managing money online and want the highest interest rate, an online bank usually wins.
What documents you need before you start
Have these four things ready before you open your process: a government-issued photo ID (driver's license, passport, or state ID card), your Social Security number, proof of your current address, and the routing and account number of another bank account you own (if you plan to fund the new account by transfer).
Proof of address can be a utility bill, lease, mortgage statement, or recent bank statement — anything dated within the last 60 days with your name and current address on it. If you do not have any of these, a credit card statement or insurance bill usually works. If you plan to deposit cash in person at a branch, you do not need proof of funds ahead of time, but you will still need the ID and Social Security number.
The online process process
Start on the bank's website or app and look for a button that says "Open an Account" or "get your free guide." The process will ask for your legal name, date of birth, address, phone number, email, and employment information. It will also ask your Social Security number — this is how the bank verifies your identity and checks for fraud. Do not be alarmed by this; every bank does it.
Next, you will choose how much to deposit to open the account. If the bank has a minimum, it will tell you the amount. You will then enter the routing and account number of the bank account you want to transfer from. The bank will pull a small amount of money (usually $0.01 to $1) from that account within one to two business days to confirm you own it. Once that transfer clears, your new money market account is officially open.
The entire process usually takes 10 to 15 minutes. Some banks will let you start using the account right away; others wait until the next business day. Check your email for confirmation and instructions on how to log in.
Opening an account in person at a branch
If you prefer to open your account face-to-face, visit a branch during business hours with your ID, Social Security number, and proof of address. Tell the employee you want to open a money market account. They will walk you through a short process on their computer or on paper, answer any questions you have, and process your initial deposit.
Bring a checkbook or debit card from another account if you want to fund the new account by transfer, or bring cash if you prefer. The employee will give you a temporary debit card or account number on the spot, and your account will be ready to use when ready or by the next business day. Ask for a receipt and written confirmation of your account number before you leave.
Funding your account after it opens
You have several ways to put money into your new money market account. The fastest is an electronic transfer from another bank account you own — this usually takes one to two business days. You can also deposit cash at a branch if the bank has physical locations, write a check to yourself and deposit it, or set up automatic transfers from your paycheck or another account.
Some banks offer a sign-up bonus if you deposit a certain amount within a set time frame — for example, $25 if you deposit $500 within 30 days. Read the account terms carefully to see if there is a bonus and what you have to do to get it. Remember that the interest rate on your money market account will change over time, so the amount you earn each month will not stay the same.
Understanding withdrawal limits and fees
Money market accounts come with a restriction: federal law allows you to make up to six withdrawals or transfers per month before the bank can charge you a fee or close the account. This includes transfers to other accounts, checks you write, and debit card withdrawals. Deposits do not count toward this limit.
If you need to withdraw money more than six times a month, a regular savings account or checking account is a better choice. Some banks waive the six-withdrawal limit during certain months or for certain account holders, so ask when you open your account. Also ask what the fee is if you exceed the limit — it is usually $10 to $25 per extra withdrawal.
Frequently Asked Questions
Can I open a money market account if I have bad credit?
Yes. Banks do not check your credit score when you open a money market account. They may check ChexSystems, a database of banking history, to see if you have unpaid overdrafts or fraud on record. If you have been denied a bank account before, ask the bank whether they use ChexSystems and what their policy is for applicants with a history of overdrafts.
What is the minimum deposit to open a money market account?
It varies by bank. Online banks often have no minimum, while traditional banks and credit unions typically require $500 to $2,500. Some banks waive the minimum for the first 30 days if you set up automatic deposits. Check the bank's website or call before you explore to confirm the minimum for the specific account you want.
How long does it take to open a money market account?
Online applications usually take 10 to 15 minutes, and your account is ready to use within one business day. In-person applications at a branch take 15 to 30 minutes, and your account is usually ready when ready. The longest part is usually waiting for a transfer from another bank to clear, which takes one to two business days.
Can I open a money market account if I do not have a Social Security number?
Most banks require a Social Security number or Individual Taxpayer Identification Number (ITIN). If you do not have either, some credit unions and community banks may open an account using a passport and other identification. Call ahead to ask whether they can work with you before you visit.
What happens if I do not meet the minimum deposit requirement?
The bank will not open the account. Some banks let you open the account with zero dollars and then deposit the minimum within a set time frame — usually 30 days. Others require the full minimum before they process your process. Check the bank's terms or call customer service to ask about their policy.
