- Vanguard, Fidelity, and Robinhood all have cash options, but they serve different users.
- Your emergency fund does not have to live at your brokerage just because your investments do.
- The best setup is often split: external high-yield savings for household safety, brokerage cash products for investing workflow.
If you invest at Vanguard, Fidelity, or Robinhood, you already face a cash decision even if you never made one. Dividends, sale proceeds, contributions, and uninvested balances all land somewhere. The question is whether that somewhere is intentional.
Quick comparison
| Platform | Cash angle | Best fit | Main caution |
|---|---|---|---|
| Vanguard | Cash Plus and money market funds | Long-term Vanguard households | Sweep versus fund distinction matters |
| Fidelity | Brokerage sweep and money market funds | Investors who want cash to earn by default | Money market funds are not FDIC insured |
| Robinhood | Gold cash sweep | Mobile investors who already value Gold | Subscription fee affects true yield |
| External bank | High-yield savings | Emergency cash | Another account to manage |
The perfect account depends on the job of the cash.
Vanguard users
Vanguard users should compare Cash Plus with Vanguard money market funds and external savings. Cash Plus can simplify cash management, while money market funds may fit investing-adjacent balances. For emergency funds, read Vanguard Cash Plus vs high-yield savings before consolidating everything.
Fidelity users
Fidelity often looks strong because idle cash may default into a competitive money market option. That is convenient, but the protection is not the same as FDIC-insured savings. A money market fund can be an excellent place for investment cash, while a direct savings account remains cleaner for household reserves.
Robinhood users
Robinhood Gold can be attractive if you already benefit from the membership. If you only want the cash APY, calculate the subscription fee first. The details are in Robinhood Gold cash sweep vs high-yield savings.
Decision rule
Keep the first layer of household safety in a direct insured account. Keep investing cash near the brokerage if the yield is competitive and the product structure is clear. Do not let default sweeps make the decision for you.
Current savings benchmark
This table is the baseline for external emergency cash. Brokerage cash options need to beat it on convenience, yield, or both.
When this recommendation changes
- Your cash will be invested soon: brokerage cash wins on workflow.
- The cash is your emergency fund: external high-yield savings wins.
- A paid subscription is required: subtract the fee before comparing.
- You hold cash above insured limits: consider multiple banks or a well-understood sweep program.
