Fidelity Cash Management Account Review

The Fidelity Cash Management Account is a brokerage account set up to work like checking. It comes with a debit card, checks, bill pay, mobile deposit and worldwide ATM fee refunds, and it has no fees and no minimum.

It can also pay you close to a savings-account rate on your balance, but only if you make one choice correctly when you open it.

The one setting that matters

Every Fidelity CMA has a core position. That's where your uninvested cash sits, and it's the source of every debit card payment, check and transfer. You choose one of two options:

The default is the FDIC sweep. It pays roughly half as much as SPAXX. On $25,000 of cash, that difference is about $375 a year.

You can change the core position in your account settings at any time.

Which should you pick? For most people, SPAXX. Government money market funds are designed to hold at $1 a share and invest in very short-term Treasury and agency debt. Choose the FDIC sweep only if you need FDIC coverage specifically. One example is a balance above SIPC's $250,000 cash limit that you want held as insured bank deposits.

What you get

• Debit card with ATM fees reimbursed at any ATM worldwide
• Free checks, bill pay and mobile check deposit
• Routing and account numbers, so it can receive direct deposit
• Zelle
• No monthly fee, no minimum, no foreign transaction fee on the debit card
• Overdraft protection from a linked Fidelity account, with no fee

What you don't get

• No cash deposits. You can't deposit cash at a branch or ATM.
• No interest on the sweep option worth having. Choose SPAXX.
• No sign-up bonus.

Can it replace your checking account?

For many people, yes. It does everything a checking account does, with no fees, refunds every ATM fee and pays more than almost any bank checking account.

The main exception is cash. If you're paid in cash or deposit it regularly, keep a local bank account for that.

Using it for an emergency fund

It works well. Money in SPAXX is available immediately by debit card, check or Zelle, so there's none of the one-to-three-day ACH wait you get with an online savings account. See how fast you can get emergency cash.

If you want a higher rate or more FDIC coverage, compare it with the other options in best cash management accounts.

Verdict

The Fidelity CMA is one of the best no-fee checking alternatives available, provided you switch the core position to SPAXX. Left on the default sweep, it's an ordinary checking account paying a below-average rate.

FAQ

Is SPAXX safe? It's a government money market fund, one of the lowest-risk investments available. It isn't FDIC-insured, and its value could in theory fall below $1 a share, though that's very rare for government funds.

Is SPAXX interest taxed? Yes, as dividends, at ordinary income rates. A portion from US Treasury holdings may be exempt from state income tax.
