Ally Bank vs Marcus by Goldman Sachs 2026: Which Online Bank Is Better?

If you’re deciding between Ally Bank and Marcus by Goldman Sachs, you’re comparing two of the best online banks in the country. Both skip the monthly fees and pay far more interest than traditional banks. But they serve different needs. This guide breaks down rates, features, and who each bank is actually best for in 2026.

Ally Bank vs Marcus: Quick Comparison

Savings Account: Marcus Pays More, But Ally Isn’t Far Behind

Marcus consistently posts one of the highest savings APYs among online banks. At 4.40%, it edges out Ally’s 4.20%. On a $20,000 balance, that difference is about $40 per year — real money, but not a dealbreaker for most people.

What matters more is what else you need. If you want a savings account only, Marcus wins on rate. If you want a full banking relationship — checking, savings, and CDs under one roof — Ally wins on convenience.

Checking Account: Ally Wins by Default

Marcus does not offer a checking account. Ally does, and it’s one of the better free checking accounts available. Ally’s checking comes with a Visa debit card, access to 43,000 Allpoint ATMs, and reimbursement of up to $10/month in out-of-network ATM fees.

If you want one bank to handle everything, Ally is the clear choice. You’ll want a separate checking account somewhere else if you go with Marcus.

CDs: Ally Has More Flexibility

Both banks offer competitive CD rates. Ally lets you choose No Penalty CDs, which let you withdraw early without a fee — a big advantage if rates keep moving. Marcus offers standard CDs with an early withdrawal penalty (90–270 days of interest depending on term).

Ally also offers a Raise Your Rate CD that lets you bump your rate once (2-year) or twice (4-year) if Ally raises its CD rates. Marcus doesn’t have an equivalent product.

Personal Loans: Marcus Is the Only Option

Marcus offers personal loans from $3,500 to $40,000 with no fees — no origination fee, no prepayment penalty, no late fee. Rates run 6.99% to 24.99% APR depending on your credit. Ally does not offer personal loans. If you want a loan from the same institution where you bank, Marcus is your only option between the two.

Who Should Choose Ally Bank?

• You want checking and savings in one place
• You need ATM access with your account
• You want CD flexibility (no-penalty or raise-your-rate options)
• You prefer a more full-featured banking experience

Who Should Choose Marcus by Goldman Sachs?

• You want the absolute highest savings rate and nothing else
• You already have a checking account elsewhere
• You might need a personal loan at a competitive rate
• You want simplicity — a savings account with no distractions

The Verdict

Marcus wins on savings rate. Ally wins on everything else. Most people are better off with Ally as their primary bank because it covers checking, savings, and CDs without needing a second institution. If you already have checking handled and just want to maximize savings interest, Marcus is a strong pick.

Either way, both banks beat traditional savings rates by a wide margin. Opening one of them is a better move than leaving money in a 0.01% account at a big bank.
