A Vanguard Cash Plus account is a money market fund that holds your cash and pays you interest while you wait to invest it elsewhere
When you open a brokerage account at Vanguard, the money you deposit needs to go somewhere until you decide what to buy. A Cash Plus account is Vanguard's answer to that question. Instead of sitting in a regular savings account earning little or nothing, your cash goes into a money market fund — a type of investment that holds very safe, short-term debt. You earn interest on it, and you can move the money out whenever you want to buy stocks, bonds, or other investments.
The account is not a bank account. It is a fund managed by Vanguard that invests your cash in things like Treasury bills and short-term corporate debt. Because these investments are extremely low-risk, the interest rate is modest — but it is usually better than what a regular savings account offers. You can see the current rate on Vanguard's website, and it changes as market conditions change.

How your money moves in and out of Cash Plus
When you deposit money into your Vanguard brokerage account, it automatically goes into Cash Plus unless you tell Vanguard to put it somewhere else. You can move money out of Cash Plus into any other investment Vanguard offers — stocks, bonds, mutual funds — with a single transaction. The money settles in one to two business days, depending on what you are buying.
If you want to withdraw cash from your Vanguard account entirely, you can transfer it back to your bank account. That transfer also takes one to two business days. There is no fee for moving money in or out of Cash Plus, and no minimum amount you have to keep in it.
Why Vanguard uses Cash Plus instead of a regular savings account
Vanguard is a brokerage firm, not a bank. It does not offer traditional savings accounts. Cash Plus exists because investors need somewhere to park money between trades, and Vanguard needed a way to hold that cash while paying interest on it. By putting your money into a money market fund, Vanguard can offer you a rate that is usually competitive with or better than what you would get at a bank.
Money market funds are considered very safe because they invest only in short-term, high-quality debt. The interest rate is lower than you might earn from stocks or bonds over time, but the risk is also much lower. For money you plan to use soon or are still deciding where to invest, that trade-off makes sense.
What interest rate you earn and how it changes
Vanguard's Cash Plus fund pays interest based on what the Federal Reserve does with interest rates. When the Fed raises rates, money market funds earn more. When the Fed lowers rates, they earn less. The current rate is published on Vanguard's website and updates regularly.
The rate you see is the same for all investors in the fund — Vanguard does not offer different rates based on how much money you have or how long you keep it there. Your interest is calculated daily and added to your account monthly. You do not have to do anything to earn it; it happens automatically.
When Cash Plus makes sense for your money
Cash Plus works well if you are saving up to invest in something specific but have not decided what yet. It also makes sense if you are waiting for a good time to buy, or if you are holding money you might need in the next few months. Because there is no penalty for moving money out, you can leave it there as long as you want.
Cash Plus is less useful if you are trying to build an emergency fund. For that, a high-yield savings account at a bank might be better because it is insured by the FDIC and offers similar or better interest rates. Cash Plus is not FDIC-insured — it is protected by different rules that explore to investment funds. If you need money to be absolutely may provide and when ready available, a bank savings account is the safer choice.
How Cash Plus compares to other places to hold cash
A high-yield savings account at a bank usually offers a similar interest rate to Cash Plus, sometimes higher. The main difference is insurance: bank accounts are FDIC-insured up to $250,000, while money market funds are not. However, money market funds are considered extremely safe because of what they invest in, and Vanguard is a large, stable company.
A regular savings account at most banks pays much less interest than either Cash Plus or a high-yield account. Money market accounts at banks are different from money market funds — they are bank products with FDIC insurance, but they often have minimum balance requirements or limits on how often you can withdraw. Cash Plus has neither.
Fees and what you actually receive
Vanguard charges a small annual fee to manage the Cash Plus fund, but it is deducted automatically from the interest you earn. The fee is very small — less than 0.1 percent per year — so most of the interest you see is what you actually keep. Vanguard publishes the exact fee in the fund's prospectus, which you can find on their website.
There are no transaction fees for moving money into or out of Cash Plus, and no minimum balance requirement. You pay nothing to open the account or to close it.
Frequently Asked Questions
Is my money safe in Cash Plus?
Cash Plus is very safe because it invests in short-term government and corporate debt, but it is not FDIC-insured like a bank account. Money market funds are regulated by the SEC and have strict rules about what they can hold. Vanguard is a large, established company. If safety and insurance are your top concern, a bank savings account is the better choice.
Can I use Cash Plus as my emergency fund?
You can, but a high-yield savings account at a bank is usually better for emergency money because it offers FDIC insurance and similar interest rates. Cash Plus works fine if you are comfortable with the slightly different protection, but most people keep emergency funds at a bank for peace of mind.
What happens to my Cash Plus money if I do not touch it for years?
It stays there earning interest. There is no time limit on how long you can keep money in Cash Plus, and no penalty for leaving it untouched. The interest rate will change as market conditions change, but your money remains available whenever you need it.
How is Cash Plus different from a money market account at my bank?

Cash Plus usually has no minimum balance or withdrawal limits, while bank money market accounts often do. Interest rates are similar, but Cash Plus may be more flexible if you plan to move money frequently.
