A CMA account is a single account that combines checking, savings, and investment features in one place

CMA stands for Cash Management Account. It's a hybrid account offered by brokerages and investment firms that lets you hold cash, earn interest on that cash, write checks, use a debit card, and invest in stocks or bonds—all from the same account. You don't need separate accounts at a bank for checking and a brokerage for investing; one CMA account does both jobs.

The account works by sweeping your uninvested cash into a money market fund or short-term securities that earn interest. When you need to spend money, you can write a check or swipe a debit card. When you want to invest, you move money from your cash position into stocks, bonds, or mutual funds without leaving the account. The interest rate on the cash portion varies by provider and market conditions—it is not fixed.

CMAs became popular in the 1980s when brokerages like Merrill Lynch created them to compete with banks. Today, most major brokerages offer some version of a CMA or call it by a similar name: Fidelity calls theirs a Cash Management Account, Charles Schwab calls it an Investor Checking account, and E*TRADE calls it a Cash Account. The structure and benefits are similar across providers, though fees and interest rates differ.

Key Takeaways

  • A CMA account combines a checking account, savings account, and investment account in one, so you can spend, save, and invest without moving money between institutions.
  • Cash you don't invest sits in a money market fund or similar vehicle and earns interest, though the rate changes with market conditions and varies by provider.
  • You can write checks and use a debit card to spend from your CMA account, just like a regular checking account.
  • CMA accounts are offered by brokerages and investment firms, not traditional banks, and typically require a minimum deposit to open.
  • FDIC insurance on a CMA account is limited to $250,000 per depositor per institution, the same as a bank account, but the structure of the account can affect how that protection works.

How money moves in and out of a CMA account

You deposit money into your CMA account the same way you would a checking account: direct deposit from your employer, transfers from another bank account, or checks you deposit. Once the money lands in your CMA account, it typically goes into the cash sweep—a money market fund or short-term bond fund that earns interest. You don't have to do anything; the sweep happens automatically.

When you spend money from your CMA account using a check or debit card, the brokerage pulls cash from your money market position to cover the transaction. If you want to invest, you move money from your cash sweep into stocks, bonds, or funds within the same account. If you need to move money out to another bank, you can request a transfer or write a check, and the brokerage will pull from your cash position to send it.

The key difference from a regular checking account is that your idle cash is working—earning interest in a money market fund—instead of sitting in a non-interest-bearing account. This is why CMAs appeal to people who keep larger cash balances; the interest adds up over time, even if the rate is modest.

Interest rates and fees on CMA accounts

The interest rate on the cash portion of your CMA account is not fixed. It moves with the Federal Reserve's benchmark rate and the rates offered by the money market funds your brokerage uses for the sweep. When the Fed raises rates, the rate on your cash sweep typically rises within weeks. When the Fed cuts rates, your rate falls. You can check your current rate on your brokerage's website or statement.

Different brokerages offer different rates on their cash sweeps, even when market conditions are the same. Fidelity, Schwab, and E*TRADE all publish their current rates publicly. Shop around if you hold a large cash balance; a difference of 0.5% on $100,000 means $500 per year. Some brokerages also offer tiered rates—higher rates if you maintain a larger balance.

Fees vary by provider. Some brokerages charge no monthly fee for a CMA account, while others charge $25 to $100 per year. Many waive the fee if you maintain a minimum balance or have a certain amount invested. Check your brokerage's fee schedule before opening an account. Some also charge for wire transfers, check printing, or expedited transfers, though many offer a certain number of these services free per month.

FDIC insurance and protection on CMA accounts

Your cash in a CMA account is covered by FDIC insurance up to $250,000 per depositor per institution. However, the way the insurance works depends on how your brokerage structures the account. Some brokerages sweep your cash into a money market fund that is not FDIC-insured but is backed by short-term government and corporate securities. Others sweep into a network of partner banks, where each bank holds a portion of your cash and FDIC insurance applies separately to each bank's portion—allowing you to have more than $250,000 protected.

Ask your brokerage directly how your cash sweep is structured and what insurance or protection applies. This matters if you hold more than $250,000 in cash. Fidelity, for example, uses a network of banks for its sweep, so balances above $250,000 can be protected. Schwab does the same. E*TRADE's sweep goes into a money market fund, which is not FDIC-insured but is backed by securities.

Your investments in stocks, bonds, and mutual funds within your CMA account are not FDIC-insured. They are protected by SIPC (Securities Investor Protection Corporation) up to $500,000 per account if your brokerage fails, but they are not protected against market losses. If you buy a stock and it drops 50%, SIPC does not restore your loss.

CMA accounts versus traditional checking and savings accounts

A traditional checking account at a bank typically earns no interest and offers FDIC insurance on balances up to $250,000. A traditional savings account earns interest but limits how many withdrawals you can make per month and does not let you invest or write checks. A CMA account lets you do all three—earn interest on cash, write unlimited checks, and invest—in one account.

The trade-off is that a CMA account is offered by a brokerage, not a bank, so the cash sweep may not be FDIC-insured (depending on the brokerage's structure). Also, if you need to access your money very quickly, a brokerage may take longer to process a withdrawal than a bank would, though most brokerages now offer next-day transfers or same-day transfers for a fee.

If you keep most of your money in investments and only need a small checking balance, a CMA account makes sense. If you keep a large emergency fund in cash and rarely invest, a high-yield savings account at a bank may be simpler and offer the same interest rate with the certainty of FDIC insurance. If you do both—invest regularly and keep a cash buffer—a CMA account consolidates everything and saves you from logging into two institutions.

Minimum deposits and account requirements

Most brokerages require a minimum deposit to open a CMA account, typically $1,000 to $25,000, though some have no minimum. Fidelity, Schwab, and E*TRADE all publish their current minimums on their websites. Some brokerages waive the minimum if you set up direct deposit or agree to keep a certain amount invested.

Once the account is open, there is usually no minimum balance requirement to keep it open, though some brokerages offer higher interest rates or waive fees if you maintain a balance above a certain threshold. Check your brokerage's terms before opening to understand what happens if your balance drops below the minimum.

You will need to provide personal information to open an account: your Social Security number, address, employment status, and investment experience. The brokerage will verify this information and may ask follow-up questions about your income or net worth. This process typically takes a few minutes online and is the same as opening any investment account.

Who should consider a CMA account

A CMA account works best for people who invest regularly and want to keep their cash and investments in one place. If you have $10,000 or more in cash you want to earn interest on while also buying stocks or funds, a CMA account simplifies your finances and puts your idle cash to work.

A CMA account also makes sense if you want to avoid the hassle of transferring money between a bank and a brokerage every time you want to invest or withdraw. With a CMA account, everything happens in one login.

A CMA account is less useful if you rarely invest, keep most of your money in cash, or need the absolute certainty of FDIC insurance on every dollar. In those cases, a high-yield savings account at a bank may be a better fit. It is also less useful if you need to access your money within hours; while most brokerages now offer fast transfers, a bank checking account is still faster for immediate access.

Frequently Asked Questions

Can I use a CMA account as my main checking account?

Yes. You can set up direct deposit, pay bills by check or debit card, and manage your everyday spending from a CMA account just like a regular checking account. The difference is that your idle cash earns interest instead of sitting unused. Many people use a CMA account as their primary account if they also invest.

What happens to my cash if the brokerage goes out of business?

If your brokerage fails, SIPC protects your investments up to $500,000 per account. Your cash is protected by FDIC insurance if it is held in partner banks (which many brokerages do), or by the securities backing the money market fund if that is how your brokerage structures the sweep. Ask your brokerage how your specific cash is protected before opening an account.

Can I earn more interest in a CMA account than in a savings account?

It depends on the brokerage and the current market. Some brokerages offer competitive rates on their cash sweeps that match or beat high-yield savings accounts. Others offer lower rates. Compare the current rates at your brokerage against rates at online banks before deciding. Rates change frequently, so check before you open.

Do I have to invest money in a CMA account, or can I just use it for checking and savings?

You do not have to invest. You can open a CMA account and use it purely as a checking and savings account, letting your cash earn interest in the money market sweep. However, if you never plan to invest, a regular high-yield savings account at a bank may be simpler and offer similar interest rates without the investment features.

Are there tax implications to holding a CMA account?

Interest earned on your cash sweep is taxable income and will be reported to you on a 1099-INT form at the end of the year. You report this interest on your tax return. Investments in stocks and funds within your CMA account follow normal tax rules: capital gains are taxable when you sell, and dividends are taxable in the year you receive them. Your brokerage will send you tax forms for all of these.
