Betterment Cash Reserve is not a traditional savings account — it's a money market fund that holds cash
Betterment Cash Reserve is a money market fund, not a bank savings account. It holds your money in short-term, low-risk investments like Treasury bills and commercial paper rather than keeping it in a deposit account at a bank. The distinction matters because it changes how your money is protected, what interest rate you earn, and how quickly you can move funds.
You access Cash Reserve through Betterment's investment platform. When you deposit money, Betterment invests it in the fund rather than holding it in a bank account. The fund pays a yield (similar to interest) that changes based on market conditions and the underlying investments. Because it's a fund, not a bank deposit, your money is not covered by FDIC insurance — it's covered by different protections tied to the securities it holds.
Many people use Cash Reserve the same way they use a savings account: as a place to park money they don't need right now but want to access without locking it up. The main trade-off is that the yield can fluctuate, whereas a traditional savings account offers a fixed rate for a set term.
Key Takeaways
- Cash Reserve invests your money in money market securities rather than holding it as a bank deposit, so FDIC insurance does not apply.
- The yield on Cash Reserve changes based on market conditions and the fund's underlying holdings, unlike a fixed-rate savings account.
- You can withdraw money from Cash Reserve without penalty, though transfers to a bank account typically take one to two business days.
- Cash Reserve is best for money you want to keep liquid and earning a competitive return, not for funds you need to access instantly.
- If you need FDIC-insured protection or a may provide fixed rate, a traditional bank savings account or certificate of deposit is a better fit.
How Cash Reserve invests your money
When you deposit money into Betterment Cash Reserve, the fund buys short-term debt securities on your behalf. These include U.S. Treasury bills (which mature in less than one year), commercial paper (short-term loans to corporations), and other money market instruments. The fund manager continuously buys and sells these securities to maintain the fund's strategy and respond to changing interest rates.
The yield you earn comes from the interest paid by these securities. Because Treasury bills and high-quality commercial paper are considered very safe, the yield is typically lower than you might earn from a riskier investment — but higher than you would get from a traditional savings account at many banks. The exact yield changes daily as the fund's holdings change and as market interest rates move.
You do not choose which securities the fund buys. That's the job of Betterment's fund managers. Your role is to decide whether the fund's overall strategy (short-term, low-risk securities) matches what you need for that portion of your money.
FDIC insurance and how your money is protected
Cash Reserve is not FDIC-insured because it is not a bank deposit. FDIC insurance only covers money held in deposit accounts at banks and credit unions. Since Cash Reserve is a money market fund, your protection comes from the nature of the securities it holds, not from federal deposit insurance.
Money market funds are regulated by the Securities and Exchange Commission (SEC) and must follow strict rules about what they can invest in. These rules require the fund to hold only high-quality, short-term securities — which means the risk of loss is very low, though not zero. If a company whose commercial paper the fund holds defaults, the fund's value could decline slightly.
If you need the certainty of FDIC insurance, a bank savings account or money market account at a bank (which is FDIC-insured up to $250,000) is the right choice. If you're comfortable with the lower but real risk of a money market fund in exchange for potentially higher yields, Cash Reserve works as a liquid holding place for cash.
Withdrawal speed and how to move money out
You can withdraw money from Cash Reserve without penalty at any time. There is no lock-up period and no early withdrawal fee. However, the speed depends on where you're moving the money.
If you're transferring to another account within Betterment, the money typically moves within one business day. If you're transferring to a bank account outside Betterment, the process usually takes one to two business days, depending on your bank and the time of day you request the transfer. Transfers requested after 4 p.m. Eastern Time may not process until the next business day.
This is slower than withdrawing from a traditional savings account at your bank, where you might see funds instantly or within hours. If you need money within hours, a savings account at your primary bank is more practical than Cash Reserve.
Comparing Cash Reserve to a traditional savings account
The key differences between Cash Reserve and a bank savings account come down to protection, rate stability, and access speed. A bank savings account gives you FDIC insurance up to $250,000, instant or same-day access to your money, and either a fixed rate or a rate that changes only when the bank decides to change it. Cash Reserve offers no FDIC insurance, takes one to two business days to withdraw to an external bank, and a yield that changes daily based on market conditions.
Neither option charges a withdrawal penalty. The choice depends on what matters most to you: if you prioritize may provide protection and instant access, a bank savings account wins. If you want to earn a higher yield on money you can afford to wait one to two business days to access, Cash Reserve may be worth considering.

When Cash Reserve makes sense for your money
Cash Reserve works well if you have money you don't need immediately but want to earn a return while keeping it accessible. Common uses include holding a portion of an emergency fund, parking money between investments, or keeping cash you plan to spend within the next few months but want to earn yield on in the meantime.
Cash Reserve is less suitable if you need instant access to your money, if you require FDIC insurance for peace of mind, or if you want a may provide fixed rate. It's also not the right tool if you're trying to build a long-term emergency fund — for that, a traditional savings account at a bank offers the certainty of FDIC protection and instant access.
Some people use both: a bank savings account for their core emergency fund (FDIC-insured, instantly accessible) and Betterment Cash Reserve for additional cash they want to keep liquid and earning yield. This approach gives you the safety of FDIC insurance where it matters most and the higher yield of a money market fund on the rest.
Fees and what it costs to hold Cash Reserve
Betterment does not charge a separate fee to hold money in Cash Reserve. However, Betterment charges an overall management fee on your account, which varies depending on your account type and balance. If you use Betterment's automated investment service, you pay a management fee (typically 0.25% per year for accounts under $100,000). If you use Betterment's self-directed brokerage, there is no management fee.
The yield you earn on Cash Reserve is the fund's gross yield minus the fund's operating expenses. These expenses are typically very low for money market funds — often less than 0.10% per year — but they do reduce the amount you take home. When comparing Cash Reserve to a bank savings account, factor in both Betterment's account fee (if applicable) and the fund's operating expenses against the bank's rate.
Frequently Asked Questions
Can I use Cash Reserve as my emergency fund?
You can use it as part of an emergency fund, but not as your only one. Because it lacks FDIC insurance and takes one to two business days to withdraw, a traditional bank savings account is safer for your core emergency money. You could keep three months of expenses in a bank savings account and additional reserves in Cash Reserve if you want higher yield on the extra amount.
What happens if Betterment goes out of business?
The money in Cash Reserve is held in the fund itself, not in Betterment's corporate accounts, so it would not be affected by Betterment's financial status. However, the fund itself could decline in value if the securities it holds lose value. This is why money market funds are considered very low-risk but not risk-free.
Is the yield on Cash Reserve may provide?
No. The yield changes based on the securities the fund holds and current market interest rates. You'll see the current yield displayed in your Betterment account, but it can go up or down. If you need a may provide rate, a certificate of deposit (CD) or fixed-rate savings account at a bank is the right choice.
Can I set up automatic deposits to Cash Reserve?
Yes. Betterment allows you to set up recurring transfers from your linked bank account to Cash Reserve, similar to automatic deposits to a savings account. This can help you build your cash reserves on a regular schedule.
How does Cash Reserve compare to a high-yield savings account?
Both offer yields higher than traditional savings accounts, but high-yield savings accounts are FDIC-insured and offer instant access, while Cash Reserve is not FDIC-insured and takes one to two business days to withdraw. High-yield savings accounts are typically safer for emergency funds; Cash Reserve is better for money you want to keep liquid and earning yield but don't need instantly.
