Marcus by Goldman Sachs — Full Review
What Marcus Gets Right
Rate competitiveness: Marcus has historically offered rates at or near the top of the HYSA market. Goldman Sachs uses Marcus as a retail funding source, giving it strong incentive to keep rates competitive.
No-penalty CD: Marcus offers a no-penalty CD that lets you withdraw your full balance (including interest) at any time after 7 days — a genuinely useful product that most banks don't offer. The rate is typically close to the HYSA rate with a small premium for commitment.
Simplicity: The product is clean. No upsell, no checking, no debt products. If you want a simple, high-rate savings account from a recognizable brand, Marcus delivers.
Brand trust: Goldman Sachs has a 155-year history. Marcus customers have access to a systemically important, well-capitalized institution — a meaningful differentiator vs. some smaller online banks.
Where Marcus Falls Short
No checking account. You can't do everyday banking at Marcus. You'll need a separate checking account at another bank, which means managing multiple relationships and dealing with transfer delays.
Slow transfers. The most consistent complaint about Marcus is transfer speed. Outbound transfers can take 3-5 business days in some cases — problematic if you need emergency access to your savings.
Limited product set. No auto loans, no investing, no money market, no debit card. Marcus is intentionally narrow.
Limited customer service hours. Phone support isn't 24/7 — compared to Ally's always-on support, this is a meaningful gap.
Ally Bank — Full Review
What Ally Gets Right
Full banking ecosystem. Checking (0.25% APY, no fees), savings (competitive APY), money market (4.40% APY with check-writing), CDs (broad term options), auto loans, and Ally Invest (brokerage). One login, one relationship, one monthly statement.
24/7 customer service. Ally's 24/7 phone and chat support is a genuine differentiator. Award-winning customer service track record going back to when it was GMAC Bank.
ATM access. Ally's checking account works at 43,000+ Allpoint ATMs fee-free, plus $10/month reimbursement for any other ATMs. No other online bank covers this as well.
Transfer speed. Ally's same-day transfers between Ally accounts and competitive ACH speeds make it practical for everyday use.
No-penalty CD and CD ladder tools. Ally makes CD laddering easy with their online tools — you can build a multi-rung ladder in minutes.
Where Ally Falls Short
APY sometimes trails Marcus. During some periods, Marcus has offered 10-20bps higher on savings. Check current rates — the gap fluctuates.
Interest checking is thin. Ally's checking account pays 0.25% APY on balances above $15,000 and 0.10% below — better than zero, but not a meaningful amount.
The Rate Gap Over Time
Both banks have been within 10-30bps of each other historically. Current rates:
- Marcus: Check current rate at marcus.com/savings
- Ally: Check current rate at ally.com/bank/online-savings-account
On a $50,000 balance, a 25bps APY difference is $125/year — real money, but for most people the product and service differences outweigh it.
Who Should Choose What
Marcus is better for:
- Savers who want the highest APY and nothing else
- People with a checking account they already love elsewhere
- Savers who don't need a debit card or ATM access on savings
Ally is better for:
- Anyone who wants one online bank for everything
- People who want checking + savings at the same institution
- Anyone who needs ATM access or faster transfers
- Savers who may need auto loans or a brokerage in the future
