Best Cash Management Accounts

Brokerage-grade cash accounts that out-pay, out-insure, and out-move regular banks.

Cash management accounts are what happens when brokerages and fintechs rebuild banking without branches: sweep networks multiply FDIC coverage far past $250k, yields track the money market instead of a rate committee, and the checking features ride along free. For anyone holding serious cash, these accounts have quietly made the standalone savings account look slow.

#1 · Best overall

Wealthfront Cash Account

9.5
Rating
APY

3.30% base (as of June 2026); up to 4.20% with new-client boost and direct deposit bump

Monthly Fee

$0

Minimum

$1

Up to $8 million of FDIC coverage through a 32-bank sweep, a 3.30% base rate that beats most household-name HYSAs, and free instant withdrawals 24/7 including weekends, the fastest cash access in the category. New clients get a 0.65% boost for three months and a permanent 0.25% bump with direct deposit. The rare account that is both the fast option and the high-rate option.

#2 · Best checking replacement

Fidelity Cash Management Account

9.3
Rating
APY

~2.7% on the FDIC sweep; or hold SPAXX money market (~3.3% 7-day yield, June 2026) as your core position

Monthly Fee

$0

Minimum

None

Choose SPAXX as your core and idle cash earns roughly 3.3% money-market yield until the second it leaves, with unlimited worldwide ATM reimbursement, full checking features, and an FDIC sweep option insured to $5 million. The 1% foreign debit purchase fee is the single wart on an otherwise complete account.

APY

0.45%

Monthly Fee

$0

Minimum

None

Every ATM operator fee on the planet rebated with no cap, plus zero foreign transaction fees on the debit card, from an institution with decades of track record. The 0.45% APY will not impress anyone, which is fine, because the linked Schwab brokerage is where idle cash should sit anyway.

#4 · Best for promotional boosts

Betterment Cash Reserve

8.0
Rating
APY

3.25% variable (as of June 2026); promotional boosts up to 4.00% for 3 months

Monthly Fee

$0

Minimum

$10

A 3.25% base with frequent boost offers, recently 0.75% extra for three months on up to $1 million, and automatic FDIC coverage to $4 million ($8 million joint) through the program-bank sweep. Goal buckets are well executed. Pick it if Betterment already runs your investments; pick Wealthfront if the cash account itself is the product.

#5 · Best for business cash

Brex Business Account

8.5
Rating
APY

Treasury money market yields ~4.01% (up to 4.36% at $20M+); checking and Vault pay nothing

Monthly Fee

$0 (Essentials)

Minimum

None (US-incorporated companies with an EIN only)

The same architecture applied to company money: Treasury yields around 4.01% with no minimum, a Vault sweeping roughly 24 banks for up to $6 million FDIC, and up to 240 checking sub-accounts, all at $0 on the Essentials tier. The headline yield is fund yield rather than FDIC interest, so size the Vault slice accordingly.

#6 · Best traditional alternative

Ally Bank Money Market Account

7.5
Rating
APY

3.10% (as of June 2026)

Monthly Fee

$0

Minimum

None

If sweep networks and fund yields feel like too many moving parts, Ally's money market pays the same 3.10% as its savings account but adds a debit card, free checks, and 43,000+ Allpoint ATMs. It is a single direct FDIC bank doing the simple version of what every account above does with machinery.

Bottom Line

Wealthfront is the strongest place to park cash in America right now: top-tier rate, effectively unlimited FDIC coverage for normal savers, and instant access that removes the classic savings-account liquidity tax. Fidelity wins if you want the account to also be your checking, and Schwab wins the moment you leave the country. The pattern across all of them is the same, which is that the $250k single-bank cap and the 1 to 3 day transfer wait are now solved problems.
