How To Open a Money Market Account in 4 Simple Steps

Blog Post Image

You open a money market based on comparing different rates online and traditional banks or credit unions and then choose an institution, apply online or in-person and fund your account. This process can happen within minutes or a few days depending on if you apply online or in-person. Here are the four steps to opening a money market account.


  • Opening deposits range widely. Expect $0 to $100 at many online banks, $25 or more at traditional banks and often $1,000 or more at credit unions.

  • Have your documents ready. You'll typically need a government-issued photo ID, your Social Security number or ITIN, a current address and an opening deposit.

  • Your money is protected up to $250,000. FDIC and NCUA insurance covers up to $250,000 per depositor, per ownership category, if the institution fails.

  • Check the withdrawal rules before you assume a limit. The federal six-per-month transfer cap was removed in 2020, but some institutions still set their own transaction limits and fees.

  • Online applications can fund the same day. Applying online is usually faster than in person, and you can often deposit your opening balance immediately.

It’s an easy process to open your money market account. Here's what to do:

Research banks and credit unions to find the money market account with a high annual percentage yield (APY), low fees and easy access. APY is the amount of money you will earn in one year on your deposit. By shopping around, you want to try to get the highest APY so your funds take advantage of compound growth. Compare minimum balances and maintenance fees so you understand what you need to keep in the account to avoid paying extra to maintain your money market account.

Pick a bank or credit union that is FDIC/NCUA-insured to protect your funds. FDIC and NCUA-insured means if the bank fails, the government protects the funds you deposited — up to $250,000 per depositor, per category and per ownership category. Select an institution that has a good reputation, great customer service and an easy-to-use app. Also, understand what's valuable to you, including in-person access or banking on the go.

Provide your name, Social Security number and address. You may also be asked to provide a driver's license. Apply in-person or online. Online applications are typically processed, and you can fund your account on the same day.

Deposit the minimum balance and set up automatic transfers. Review the account periodically so you don't dip below the minimum balance. Make sure you stay within your transaction limit, so you don't pay a fee.

No matter where you apply for a money market account, you'll need to have your documentation ready. Here's what you'll need.

To open your money market account, you’ll need specific information and items. Here's what they are:

  • Government-issued photo ID, e.g., driver's license, passport or state ID

  • Social Security number or Individual Taxpayer Identification Number (ITIN)

  • Current mailing address

  • Employment status and income details

  • Opening deposit to meet the account's minimum balance requirement

  • Existing bank account or debit card, if funding electronically

Requirements may vary across different financial institutions. Check those requirements before applying to save yourself some time.

The typical minimum amount you need to deposit in your money market ranges between $0 to a few thousand dollars. Minimum deposits for money market accounts depend on the financial institution. If you fail to meet the minimum balance at any time, you may be charged a fee.

If you want the lowest barrier to entry, an online bank is probably your best option. Minimum deposits vary considerably at traditional banks and credit unions.

Money market accounts and savings accounts both earn interest. However, some financial institutions may limit certain withdrawals, while savings accounts usually have unlimited access. Here's how they stack up in terms of APYs, minimum balances, monthly fees, check writing and debit card access.

  • You’re saving for a bigger goal like a down payment for a home or purchase of a car.

  • You already have a savings account and want to earn higher interest on an additional savings vehicle.

  • You're trying to build an emergency fund.

  • You want to avoid the risk of overdraft fees.

Financial institutions don't check your credit if you want to open a money market account. They typically review the ChexSystems to look at your bank history. Bad credit alone won’t be a bar to open your money market account.

There isn't a traditional withdrawal penalty for money market accounts. However, if you exceed the transaction limit you will be charged an excessive transaction fee.

With an online institution, you can open and fund your money market on the same day.

Money market account fees vary by the financial institution. Some may charge a fee for excessive transactions and account balances falling below the minimum balance.

You can have multiple money market accounts at several institutions including traditional banks, online banks and credit unions.


  • Money market account (MMA): A deposit account at a bank or credit union that usually pays higher interest than a standard savings account and may offer check-writing or a debit card.

  • Annual percentage yield (APY): The total interest you earn in a year, including compounding — the number to compare when shopping for an account.

  • FDIC insurance: Federal Deposit Insurance Corporation coverage that protects bank deposits up to $250,000 per depositor, per ownership category, if the bank fails.

  • NCUA insurance: The credit union equivalent of FDIC coverage, protecting deposits up to $250,000 per member, per ownership category.

  • Minimum opening deposit: The amount you must deposit to open the account, ranging from $0 at some online banks to $1,000 or more at some credit unions.

  • Minimum balance requirement: The balance you must keep to earn the stated APY or avoid a monthly maintenance fee.

  • Tiered interest rate: A structure where your APY changes based on your balance level.

  • ChexSystems: A reporting agency banks may check to review your past deposit-account history when you apply.
