Ally Bank
Best all-in-one bankingFounded in 2009 from GMAC, Ally is the most established online bank in this comparison. Rates from 4.00% APY on savings — tied with Discover, 10 bps below Marcus. Where it wins is everything else: checking account with a debit card, Zelle, the Savings Buckets feature (sub-accounts for specific goals within one savings account), and the largest ATM network of the three (98,000+ machines across Allpoint and MoneyPass networks).
- Rates up to 4.00% APY — competitive, no requirements
- Savings Buckets: organize money into named goals within one account (vacation, car, emergency fund)

The differentiator is the Cashback Debit checking account: 1% back on up to $3,000 in debit purchases per month ($360/year maximum), which is unusual in a world where most checking accounts pay zero. Best if you already have a Discover credit card and want everything on one network.
- Rates up to 4.00% APY on savings — tied with Ally, no requirements
- 1% cashback on debit purchases (checking, up to $3,000/month) — most accounts pay zero
- Strong ecosystem integration if you have a Discover credit card

How much more does Marcus earn vs Ally or Discover?

Annual interest estimates based on stated APYs, compounded daily. Actual interest will vary. Rates subject to change — verify with each bank before opening.
The verdict on the rate gap:On a $10,000 balance, Marcus earns roughly $10 more per year than Ally or Discover. That's small enough that the decision should be made on features, not rate alone — unless your balance is very large ($50K+) where the difference becomes more meaningful. If you need Zelle, savings buckets, or a cashback debit card, the rate gap doesn't justify picking Marcus.
