Worked example: $50,000 parked for 1 year
| Scenario | Capital One 360 (4.10% APY) | Marcus (4.40% APY) |
|---|---|---|
| Starting balance | $50,000 | $50,000 |
| 1-year interest (simple) | $2,050 | $2,200 |
| Ending balance | $52,050 | $52,200 |
| Difference | $150/yr — favor of Marcus | |
$150/year is real money — but read the caveat: both rates float. The bank paying more this month may pay less in 6 months. Online HYSAs typically stay within 20-40 bps of each other over time; the leader rotates.
Both banks: rate history reality check
In 2021, the top online HYSAs paid 0.40-0.55% APY. By late 2023 they were paying 4.50-5.30%. As the Fed cut rates from 5.50% to 4.50% in 2024-2025, top HYSAs fell 50-75 bps. Whatever Capital One 360 or Marcus pays today is not what you'll earn three years from now.
If you want a rate locked, that's not what these accounts do. Read the MYGA section below.
If you want better than either: a MYGA
Both HYSAs above are variable rate. They were paying 0.50% in 2021. They might be paying 2.00% in 2027. You don't lock the rate — you take whatever the bank chooses to credit each month.
If you have cash you genuinely don't need for 3+ years (emergency fund excluded), the closest fixed-rate equivalent is a multi-year guaranteed annuity (MYGA):
- 3-year MYGAs: ~5.40-5.65% locked (A-rated carriers)
- 5-year MYGAs: ~5.50-5.75% locked
- 7-year MYGAs: ~5.60-5.85% locked
- 10-year MYGAs: ~5.70-6.10% locked (mostly via secondary-market carriers)
Trade-offs vs. an HYSA:
- FDIC ($250K/bank) vs. state guaranty fund ($250K-$300K/carrier — varies by state)
- Withdraw anytime vs. 10% free withdrawal/year + surrender charges in years 1-N
- Taxable interest each year (1099-INT) vs. tax-deferred until withdrawal (1099-R)
- Variable rate (resets monthly) vs. fixed rate (locked for entire term)
MYGAs don't replace your emergency fund. They replace the excess cash sitting in an HYSA that you know you won't touch for 3-10 years.

Frequently Asked Questions
Is Capital One 360 or Marcus better for a 65-year-old retiree?
For pure HYSA use (emergency fund + short-term cash), the bank with the higher APY today wins on dollars and the bank with better ATM access wins on convenience. Capital One 360 pays 4.10% and Marcus pays 4.40%. If the retiree has $200K+ sitting in cash they won't touch for 3-5 years, neither HYSA is the right product — a MYGA at 5.50-5.75% locked is. HYSAs are right for cash you might need in 0-24 months.
Are Capital One 360 and Marcus both FDIC-insured?
Yes. Capital One 360 is FDIC-insured under cert #33954. Marcus is FDIC-insured under cert #33124. Both are covered up to $250,000 per depositor, per ownership category, per insured bank. If you hold a joint account, coverage doubles to $500,000 on that account.
Can I have accounts at both Capital One 360 and Marcus?
Yes. There's no rule limiting you to one HYSA. Many savers split deposits across 2-3 banks for FDIC coverage above $250K, or to chase the highest APY without closing accounts. Capital One 360 and Marcus are separate FDIC-insured institutions, so $250K at each = $500K of insured deposits.
How long do Capital One 360 and Marcus transfers take?
Capital One 360 ACH transfers settle in 1-3 business days. Marcus ACH transfers settle in 1-3 business days. Same-day wires are available at most banks for a fee ($15-30 outbound). Mobile check deposit usually clears next business day with a hold on amounts over $5K.
Which bank has the better mobile app — Capital One 360 or Marcus?
Capital One 360: 4.8/5 (iOS) / 4.7/5 (Android). Marcus: 4.7/5 (iOS) / 4.6/5 (Android). Both are well-rated. The differences come down to UX preferences (transfer screens, statement export, biometric login). Both support mobile check deposit, external account linking, and goal-based saving features.
Do Capital One 360 or Marcus charge any hidden fees?
Neither bank charges monthly maintenance fees or transaction fees on the standard savings account. Capital One 360: $0 monthly fee. Marcus: $0 monthly fee. Watch for outbound wire fees ($15-30), expedited check delivery fees, and overdraft fees if you link the savings to a checking account that overdrafts (rare on savings).
What's a better option than Capital One 360 or Marcus for $100K+ I won't touch for 5 years?
A multi-year guaranteed annuity (MYGA) at 5.50-5.75% locked for 5 years from an A-rated carrier. HYSAs are variable; MYGAs are fixed. On $100K over 5 years, the difference between a 5.65% locked MYGA and a 4.20% variable HYSA (with realistic rate-cut assumptions) is roughly $7,000-12,000. Trade-off: MYGAs have surrender charges in years 1-5 and only allow ~10% free withdrawals per year. Right for parked cash; wrong for an emergency fund.
Want a fixed rate locked for 3-10 years instead of a variable HYSA?

HYSA rates move every month with the Fed. If you want a rate locked for 3, 5, 7, or 10 years on cash you won't touch, a MYGA (multi-year guaranteed annuity) is the closest equivalent. Current top MYGA rates: 5.40-5.75% for 3-5 year terms, fixed. Tax-deferred. State guaranty fund backed.
