Is the Vanguard Cash Plus Account worth it?

We source this rate from our data partner and The Vanguard Group, our verified data partners. It carries our ◆ Partner data label — we did not fetch it from the provider ourselves.
A cash management account is offered by a brokerage or fintech, not a bank. It sweeps your uninvested cash to partner banks that are FDIC members, which extends coverage well beyond the standard $250,000 per-bank limit. That makes it a handy place for cash you want to keep liquid next to your investments.
The honest caveats: the APY is partner-supplied and variable, and insurance comes through the program banks rather than the provider directly. Confirm the current rate and the program-bank list on the provider’s own site. This is not financial advice.
How does a high-yield savings account work?
A high-yield savings account holds cash and pays interest, quoted as an annual percentage yield (APY). The bank can change a variable APY at any time, and federal rules may limit certain withdrawals. Interest compounds — usually daily or monthly — and is taxable income in the year you earn it.
How much could you earn with the Vanguard Cash Plus Account?
At a 3.1% APY, a $10,000 balance in the Vanguard Cash Plus Account earns about $310 in interest over a year, before taxes. Double the balance and you roughly double the interest; your real return depends on how long the rate holds.

Common mistakes to avoid with a high-yield savings account
- Chasing a teaser rate without checking the ongoing APY or any balance tier needed to earn it.
- Leaving an emergency fund in a 0.01% big-bank account instead of a high-yield account.
- Assuming the APY is fixed — it is variable and can drop after you open.
- Overlooking transfer times: moving money to a linked bank can take one to three business days.
