Best Cash Management Accounts, Ranked by Coverage and Rate

A cash management account is a brokerage-held account that pays savings-like interest and often spreads your money across multiple partner banks for insurance that can exceed the standard $250,000 FDIC limit. Wealthfront currently pays the highest advertised rate at 4.20% APY with up to $8 million in coverage, per Forbes Advisor’s July 1, 2026 review. The right one depends on how much cash you’re protecting and whether you want checking features attached.

What Is a Cash Management Account, Exactly?

A cash management account, or CMA, is a hybrid product offered by brokerages rather than banks. Your deposit doesn’t sit in one FDIC-insured institution. It gets automatically swept across a network of partner banks, each covering up to $250,000 per depositor.

That sweep mechanic is the whole point. Spread $600,000 across four partner banks and every dollar is still FDIC-insured, without you opening four separate accounts yourself. A plain savings account can’t do that.

The complication is that a CMA isn’t a bank account at all. Legally, it’s a brokerage account holding either a money market mutual fund or a deposit-sweep arrangement. That distinction matters the moment something goes wrong with the brokerage itself, which we’ll get to.

The typical CMA holder isn’t chasing the single highest rate available anywhere. They’re usually someone who already keeps a brokerage account open for investing and would rather manage idle cash from that same login than open a separate savings account at a separate bank. A close second group is people with balances well above $250,000 who want the insurance math handled automatically instead of manually splitting funds across several banks themselves.

How the Sweep Actually Works

Here’s the mechanical path your deposit takes, in order:

You deposit cash → the brokerage’s sweep program allocates it across a list of partner banks → each partner bank insures up to $250,000 per depositor under its own FDIC charter → your combined balance stays insured as long as no single bank’s slice exceeds that limit → withdrawals pull back through the same brokerage layer, typically settling in one to three business days.

Every provider publishes its own “list of program banks.” Check it before you deposit a large balance — the advertised maximum coverage assumes the sweep actually spreads your money across enough separate banks, which only happens automatically once your balance is large enough to trigger the next tier.

Here’s what that looks like with real numbers. Say you deposit $2 million into a CMA with a four-bank sweep network. If the program splits it evenly, each bank holds $500,000, which is $250,000 over its own insurance cap. The provider only closes that gap once its network includes enough banks to spread you thin, in this case, at least eight. That’s why the “$8 million” headline number on some of these accounts describes the ceiling of a fully built-out network, not a guarantee that your specific balance today is spread that wide.

Five Terms Worth Knowing Before You Compare These

• Sweep program: the automated system that spreads your cash across partner banks for insurance purposes.
• Program bank: one of the partner banks in a sweep network, each with its own $250,000 FDIC cap.
• SIPC: Securities Investor Protection Corporation — protects against a brokerage losing your securities or cash, not against market losses. Caps at $500,000 per account, including $250,000 for cash.
• Money market sweep: an alternative to a bank sweep, where uninvested cash sits in a money market mutual fund instead — SIPC-protected, not FDIC-insured.
• Rate boost: a temporary promotional APY add-on for new customers that expires after a set window, usually 90 days.

The Best Cash Management Accounts Right Now

Forbes Advisor’s July 1, 2026 review, described as “last audited and verified” on that date, ranked these seven accounts at the top of the category.

*Includes a temporary new-client rate boost. See the mistakes section below for what each reverts to.

Each Provider, Broken Down

Wealthfront: the top rate, boosted

Wealthfront’s 4.20% APY includes a 0.65 percentage point boost for new clients over the first three months. The unboosted base rate runs lower. What doesn’t expire is the $8 million coverage ceiling and the $1 minimum, which makes this an easy account to open just to have available.

Betterment: aggressive promo, steeper reversion

Betterment’s 4.00% APY carries a 0.75 point promotional boost for three months before dropping to a variable 3.25%. That’s a bigger drop than Wealthfront’s. Worth it if you’re comfortable moving cash again in 90 days; less so if you want to set it and forget it.

MaxMyInterest: highest real rate, smallest brokerage

MaxMyInterest pays 3.41% APY with no promotional asterisk attached, the highest genuinely standing rate on this list. The trade-off is a 0.04% quarterly fee with a $20 minimum charge, and it isn’t a full brokerage, just a cash-optimization layer.

Vanguard Cash Plus: brand trust, smaller network

Vanguard’s 3.35% APY includes a 0.25 point boost through September 30, 2026. Coverage tops out at $1.25 million, smaller than several competitors, and there’s a $25 annual fee that’s waivable under certain conditions. Vanguard’s institutional reputation is the real draw here, not the number on the rate sheet.

Webull: built for traders who also want to park cash

Webull pays 3.35% APY with $5 million in coverage and no minimum. It comes bundled with commission-free stock, ETF, and options trading, and crypto access. If you don’t want any of that, it’s a lot of unused surface area attached to a savings account.

Public: clean and limited

Public pays 3.30% APY with $5 million in coverage and no fees. There’s no checking functionality at all, which keeps it simple but rules it out as a primary spending account. Public built its name on fractional stock and options trading, so the cash account reads more like a parking spot for money waiting to be invested than a destination in its own right.

Empower: strong coverage, thin feature set

Empower pays 3.00% APY, the lowest advertised rate here, with $5 million in coverage. There’s still no debit card as of this writing, and the account leans toward funneling you into Empower’s advisory services over time. If you’re already a client of Empower’s financial planning tools, the integration is convenient; if you’re shopping purely on rate, this is the one to skip.

How Sweep Rates Move With the Fed

None of these APYs are fixed. Sweep-network rates track the Federal Reserve’s target range the same way high-yield savings rates do, usually adjusting within one to two weeks of an FOMC decision rather than instantly.

The lag matters more here than at a typical bank. A provider running deposits through several partner banks has to update pricing across that whole network, and some banks in the sweep move faster than others. That’s part of why non-promotional rates like MaxMyInterest’s 3.41% sit close to each other across providers: they’re all chasing the same underlying benchmark, just through different plumbing.

Promotional rates behave differently. Wealthfront’s and Betterment’s boosted APYs are set by marketing budgets, not the Fed, which is why they expire on a fixed calendar date instead of floating with rate policy. Watch your account around both dates: the day your promo ends, and the days following any Fed meeting.

If the Fed holds rates steady for an extended stretch, expect these APYs to stay roughly where they are, aside from promo expirations running their course. If it cuts, the reverted long-run rates, Betterment’s 3.25% among them, will likely drift down first, since providers unwind promotional pricing faster than they adjust base sweep rates.

Which of These Is Actually Wrong for You?

Cash Management Account or Plain Savings Account?

Neither wins outright. It genuinely depends on your balance.

• Under $250,000 → a single FDIC-insured high-yield savings account covers you completely. A CMA adds complexity you don’t need yet.
• $250,000 to $1 million → a CMA’s multi-bank sweep starts earning its keep, since spreading that across separate savings accounts yourself means juggling three or four logins.
• Over $1 million → coverage ceiling matters more than APY. Wealthfront’s $8 million ceiling or Betterment’s $4–8 million range clear more room than Vanguard’s $1.25 million.
• You want checking, bill pay, and a debit card in one place → most CMAs handle this better than a pure savings account, which usually doesn’t.

Moving Your Cash Into a CMA Without a Coverage Gap

If you’re moving a meaningful balance out of a single bank, do it in this order so you’re never uninsured, even briefly:

1. Confirm the current program bank list before you transfer anything. Every provider publishes this, usually in a help-center article or account disclosure. Note how many banks are on it today, since that number changes.
2. Calculate your actual coverage at today’s network size, not the advertised ceiling. Divide your balance by the number of program banks currently active. If any bank’s slice would exceed $250,000, ask the provider how it handles the excess before you fund the account.
3. Leave your old account open until the new one shows a confirmed balance. Don’t close a fully insured account and wait for a transfer to land; keep both funded until you can see the money has arrived and been swept.
4. Transfer in stages if the balance is large. Moving $2 million in one transaction gives the sweep program less room to react than moving it in three or four pieces over a couple of weeks.
5. Recheck the program bank list every six to twelve months. Networks shrink when a partner bank exits and grow when a new one joins. The coverage math you did on day one won’t necessarily hold a year later.

None of this is complicated once you’ve done it, but skipping the order, closing the old account first or transferring the full balance in one shot, is exactly how people end up with a stretch of partially uninsured cash for no reason.

What $500,000 Looks Like, Insured Two Different Ways

A worked comparison makes the coverage math concrete. Half a million dollars, one lump sum, insured two different ways:

That’s the entire case for a CMA in one sentence: it automates what would otherwise take three to four separate bank relationships to insure the same lump sum. Below $250,000, that automation buys you nothing you couldn’t get from one good savings account.

The Mistakes That Quietly Cost You Here

What People With Real Money Actually Do

People managing balances above the standard FDIC limit tend to split cash two ways rather than one: a high-yield savings account for money they might need same-week, and a CMA for the larger cushion they’re less likely to touch. That split hedges against both a bank’s ACH delays and a brokerage’s sweep quirks at once.

They also re-check the program bank list annually, not just at signup. Sweep networks change providers over time, and a network that covered $8 million in 2026 could shrink or grow by 2027.

A smaller but growing group also ladders CDs alongside the CMA-and-savings split, especially once the Fed signals it may start cutting. Locking part of the balance in a CD hedges against sweep rates drifting lower, while the CMA portion stays liquid for whatever comes up first.

Key Takeaways

• Wealthfront currently advertises the highest CMA rate at 4.20% APY, though that includes a temporary new-client boost, per Forbes Advisor’s July 1, 2026 review.
• MaxMyInterest’s 3.41% APY is the highest non-promotional rate on this list.
• Standard FDIC coverage at one bank is $250,000 per depositor, per ownership category; CMA sweep networks can extend that to $1.25 million–$8 million depending on the provider.
• SIPC protection (used by some money-market sweep options) caps at $500,000 per account and covers missing assets, not market losses.
• Under $250,000, a plain high-yield savings account does the same job with less complexity.
• Every provider’s advertised coverage ceiling assumes your balance is large enough to actually spread across every partner bank in its network.

Frequently Asked Questions

What is a cash management account?

A cash management account is a brokerage-held account that combines savings-like interest with checking-like features, often sweeping deposits across multiple partner banks for expanded FDIC insurance beyond the standard $250,000 single-bank limit.

Is a cash management account better than a savings account?

It depends on your balance. Below $250,000, a high-yield savings account is simpler and equally well-insured. Above that, a CMA’s multi-bank sweep can insure a larger lump sum without you managing several separate bank accounts yourself.

How is my money protected in a cash management account?

Most CMAs use FDIC-insured deposit sweep programs, spreading your cash across partner banks at up to $250,000 each. Others use SIPC-protected money market funds instead, which cap at $500,000 per account and cover missing securities rather than bank failure.

Can I write checks from a cash management account?

Many can, though features vary widely by provider. Some, like Public in this comparison, offer no checking functionality at all, while others bundle a debit card, bill pay, and check-writing alongside the cash yield.

Do cash management accounts have monthly fees?

Most of the providers compared here charge no monthly fee. A few charge something else instead, like MaxMyInterest’s quarterly percentage fee or Vanguard’s waivable annual fee, so check the fee structure, not just the advertised rate.

What happens if my CMA provider fails?

If the brokerage itself fails, SIPC steps in for missing securities and cash up to $500,000 per account. If a specific partner bank in the sweep network fails, FDIC insurance covers your slice at that bank up to $250,000, and the rest of your sweep balance at other banks remains unaffected.

Cash management account vs. money market account: what’s the difference?

A money market account is a bank product, FDIC-insured directly, usually with a debit card and limited check-writing. A cash management account is a brokerage product that may use either a bank sweep or a money market mutual fund, with insurance handled differently depending on which structure it uses.

Can I lose money in a cash management account?

Your principal isn’t exposed to market swings the way it would be in a brokerage account holding stocks. The realistic risks are a rate drop after a promotional period ends, or, in the rare case of a brokerage failure, a temporary gap while SIPC or the sweep program sorts out your claim.

How do I open a cash management account?

You open it directly through the provider’s brokerage platform, the same way you’d open any brokerage account, then either transfer cash in or link an external bank account for an ACH deposit. Most providers activate the sweep automatically within a few business days of funding.
