Quick take: Betterment Cash Reserve is a sweep-style HYSA paying ~4.00% variable APY with FDIC coverage up to ~$2 million via Betterment's partner-bank network. Like Wealthfront's Cash Account, it is NOT a CD — the rate is variable, no lockup. For rate certainty, a CD or MYGA is the right tool.
| Term | APY | Minimum |
|---|---|---|
| Betterment Cash Reserve (variable, sweep) | ~4.00% APY | $10 |
| Betterment Cash Reserve (with new-customer boost) | ~4.50% APY for 3 months | $10 |
| (Comparison) Marcus Online Savings | ~3.85% APY variable | $0 |
| (Comparison) Ally 11-Mo No-Penalty CD | ~4.20% APY locked | $0 |
| (Comparison) BMO Alto 1-year CD | ~4.75% APY locked | $0 |
| (Comparison) BrioDirect 1-year CD | ~4.85% APY locked | $500 |
| (Comparison) Top A-rated 5-year MYGA | ~5.65% APY locked (tax-deferred) | $25K+ typical |

Betterment LLC is an SEC-registered investment adviser, not a bank. Cash Reserve is a sweep program that distributes customer deposits across a network of partner banks (Green Dot Bank, Wells Fargo, and others over time). Each partner bank provides FDIC insurance up to $250,000 per depositor; the sweep aggregates coverage to roughly $2 million per Betterment account.
The APY is variable. Betterment runs periodic promotional rates (~4.50% APY for 3 months) for new customers. The standard rate (~4.00%) tracks the short end of the yield curve.
Betterment's value proposition for Cash Reserve overlaps Wealthfront's: a sweep-style HYSA for users already in the Betterment advisor platform. The $2M FDIC aggregate is lower than Wealthfront's ~$8M but still useful for households above the single-bank $250K cap.
For locked rate, Betterment Cash Reserve loses to even the Ally No-Penalty CD (4.20% locked) at the short end, and loses badly to standard 1-year CDs (BMO Alto 4.75%, BrioDirect 4.85%) at the medium end. The Cash Reserve is purely a liquid-cash product, not a yield-maximizer.
If this rate is on your shortlist, you should also be pricing:
| Competitor | Term | APY |

| Wealthfront Cash Account (similar product) | Sweep, $8M FDIC | ~4.00% APY |
| Marcus Online Savings | Variable HYSA | ~3.85% APY |
| Ally 11-Month No-Penalty CD | 11-month with flex | ~4.20% APY |
| BMO Alto 1-year CD | 1-year locked | ~4.75% APY |
| Top A-rated 5-year MYGA | 5-year locked, tax-deferred | ~5.65% APY |

For 5-year retirement money, a MYGA dramatically outperforms Cash Reserve. Compare $250,000 over 5 years:
Betterment Cash Reserve is a fine place to hold a 6-12 month emergency fund. For retirement money you won't touch for 5 years, the locked MYGA produces meaningfully more wealth and removes the rate-cut risk.

CDs are safe and simple. MYGAs are insurance-company versions of CDs, often paying 50-150 bps more for the same lockup. The math depends on your tax bracket and state guaranty fund coverage.

Betterment Cash Reserve is a competent sweep-style HYSA for users already in the Betterment ecosystem — not a substitute for a CD or MYGA when you want rate certainty. For liquid 6-12 month emergency cash, it's fine. For locked 1-year money, a standard CD (BMO Alto, BrioDirect) pays 75-85 bps more. For locked 5-year retirement money, a top-rated MYGA pays 165+ bps more.

This review reflects publicly available bank rate sheets and approximate APYs as of the date stated above. CD rates change frequently — sometimes weekly — and the rates above may be stale by the time you read this. Always confirm current rates and terms against the bank's current rate sheet and disclosure documents before opening an account. FDIC insurance covers $250,000 per depositor, per insured bank, per ownership category; deposits above that amount at a single bank are not insured. This article is general information for educational purposes; it is not personalized financial advice, a solicitation, or an offer of any specific product. Hans Goldstein is an independent licensed insurance producer (NPN 20602398) and is not a bank, deposit broker, or registered investment adviser. CDs are bank deposit products and are not sold by insurance producers; references to CDs are for comparison context only. MYGAs (multi-year guaranteed annuities) are insurance contracts, subject to surrender charges and state guaranty fund coverage rather than FDIC. Early withdrawal of a CD before the maturity date typically results in a penalty that may exceed interest earned. Always read the actual deposit account agreement and consult a licensed advisor before making material financial decisions.
