How Much More Does Marcus Pay? A Real Dollar Example
The APY gap is small, but let’s put it in dollar terms across three common savings amounts.
| Balance | AmEx @ 3.10% | Marcus @ 3.50% | Annual Difference |
|---|---|---|---|
| $10,000 | $310 | $350 | $40 |
| $25,000 | $775 | $875 | $100 |
| $50,000 | $1,550 | $1,750 | $200 |
AmEx at about 3.10% per The Motley Fool (September 28, 2026); Marcus per Bankrate (October 15, 2026). At $50,000, Marcus paid about $200 more a year at these rates. Both accounts compound interest daily and credit it monthly, so your balance grows every day regardless of which you choose.
Bottom line on APY: The difference is real but modest at typical savings balances. At $50,000, Marcus pays about $150 more per year. If you’re opening a new account from scratch and rate is your primary criterion, Marcus’s higher rate makes it the natural pick.
CD Comparison: Marcus Has the Edge, But AmEx Competes on Terms
Both banks offer certificates of deposit, but their product lineups differ meaningfully.
Marcus CDs:
- Standard term CDs from 6 months to 6 years
- No-penalty CD (7-, 11- and 13-month terms) — withdraw the full balance starting 7 days after funding, no penalty
- Competitive APY across all terms
AmEx CDs:
- Terms up to five years (minimum and penalties not shown on its page)
- No no-penalty CD found on its page
See our American Express CD rates page for what the bank says about its CDs, and Marcus CD rates for Marcus’s dated rates.
If you want to lock in today’s rates but aren’t 100% sure you won’t need the money early, Marcus’s no-penalty CD is a genuinely useful option that AmEx can’t match. If you’re confident the funds are untouched until maturity, compare the rates each bank shows for your term.
Account Access, Transfers, and Daily Limits
Neither AmEx nor Marcus is a full-service bank — there’s no debit card, no ATM access, and no checking account at either institution. Both are savings-only platforms. To access your money you transfer to a linked external account, which typically arrives in 1–3 business days.
Transfer limits differ significantly:
- AmEx: Outbound transfers are capped at $35,000 per day
- Marcus: Outbound transfers are capped at $125,000 per day — substantially more flexible for large balances
For most savers with balances under $50,000, the AmEx limits are fine. But if you’re holding a large emergency fund or cash reserve and need to move a significant amount quickly, Marcus’s higher transfer ceiling is a real practical advantage.
