A cash management account, or CMA, is a hybrid account that combines the features of a checking and a savings account. The main difference: A CMA is not a bank account. It’s typically offered by brokerages, making it a solid companion to an investment account and a place to keep your uninvested cash, especially if you have a lot of it. CMAs can insure more cash than the standard amount banks and credit unions cover.
How does a CMA work?
With a CMA, you can make transactions, write checks, earn high-yield interest and sometimes use a credit line that’s attached to your investment securities.
Like with savings accounts, CMA rates are also variable and can change at any time.
But your money is insured differently with a CMA. Because brokerages and fintechs are not banks, they can’t offer federal insurance themselves. Instead, they sweep your money into third-party banks to get your Federal Deposit Insurance Corp. coverage.
The upside: They can sweep your funds into multiple banks, giving you multiple times the usual coverage: Of the five CMAs NerdWallet reviews, FDIC insurance limits range from $1.5 million to up to $8 million.
The downside: This insurance is what’s called pass-through FDIC insurance. It covers your money in the event the partner bank fails, not in the event your brokerage or fintech goes out of business.

Why choose a CMA?
Simplified account ownership. A CMA can streamline your finances by being your checking and savings at once. And since it’s offered by a brokerage, you can easily connect it to your investment accounts, too, all without having to transfer funds between different accounts.
Expert on the ground
High interest rates. Cash management accounts have annual percentage yields that are higher than what most brick-and-mortar banks offer, and they rival many online bank high-yield savings account APYs, too. For example, rates for the cash management accounts we review are similar to the rates offered by the best high-yield online savings accounts.
APYs for CMAs NerdWallet covers:
Betterment Checking and Cash Reserve Account: 4.25% APY with boost; base rate is 3.50% APY

More federal insurance. If you have a lot of cash on hand — more than $250,000 — and want it all insured, a CMA can meet your needs because it can sweep your funds into partner banks, giving you more coverage, with the caveat that it’s pass-through FDIC insurance and functions differently than standard FDIC insurance.
Should you swap your HYSA for a CMA?

Other accounts or investments may give you higher returns
If you have money you won’t need for a long time, you can consider investing it instead. You can get higher returns, though you take on the risk of losing money, too. Avoid investing money you’ll need in the next three to five years.
If you don’t want the gamble of the stock market but you do want high and guaranteed returns, consider opening a certificate of deposit. You can earn rates that are as high or higher than what you’ll find with the best CMAs. And unlike CMA rates, CD rates will be locked in for the duration of your CD.

Is a CMA right for you?
Consider a CMA if you:
Want one account for checking and savings.
Need quick access to your savings, even if you keep your checking elsewhere.
Want your money easily connected to your investing account.
Want to earn a good yield on all your money, not just savings.
Need insurance past the regular FDIC limits.
Like online banking.
A CMA may not be right for you if:
You want to keep your savings and checking funds more separated. Though you don’t have to use your CMA as both your checking and savings, you can. If you want your savings to be less accessible, this isn’t the right account for you.
You need in-person customer service. Like online banks, the brokerages that offer CMAs tend to have remote customer service like online chat or phone support.
