Discover Bank and Capital One 360 are two of the longest-running online banking platforms — both backed by major financial companies with decades of experience. They offer similar products (savings, checking, CDs, money market) with no monthly fees, but each has a standout feature the other can’t match: Discover’s 1% cashback checking and Capital One’s in-person Café network. Here’s the full comparison.
TL;DR: Discover Bank wins with its unique cashback debit account (1% on debit purchases, up to $360/year), strong customer service, and competitive rates. Capital One 360 wins with cash deposit access (Cafés and ATMs), a larger fee-free ATM network, and its credit card ecosystem integration.

Savings rates are nearly identical. The difference is typically $0-$25/year on $25,000 — not enough to choose one over the other based on savings APY alone.

Cashback Debit: Discover’s Killer Feature
| Monthly Debit Spending | Cash Back (1%) | Annual Cash Back |
|---|---|---|
| $500 | $5 | $60 |
| $1,000 | $10 | $120 |
| $1,500 | $15 | $180 |
| $2,000 | $20 | $240 |
| $3,000 (max qualifying) | $30 | $360 |
No other major bank pays cash back on debit card purchases. If you use your debit card regularly, Discover’s cashback checking is worth $60-$360/year — significantly more than Capital One’s 0.10% interest on a typical checking balance.
Interest vs Cash Back: Which Is Worth More?
| Checking Balance | Capital One Interest (0.10%) | Discover Cash Back (assumes $2K/mo debit) | Winner |
|---|---|---|---|
| $1,000 | $1/year | $240/year | Discover |
| $5,000 | $5/year | $240/year | Discover |
| $10,000 | $10/year | $240/year | Discover |
| $50,000 | $50/year | $240/year | Discover |
Discover’s cash back wins over Capital One’s checking interest at any realistic balance. The cash back is dramatically more valuable.
CD Comparison
| Term | Discover CD APY | Capital One 360 CD APY | Higher |
|---|---|---|---|
| 3-month | 3.50% | 3.50% | Tie |
| 6-month | 3.75% | 3.75% | Tie |
| 12-month | 4.10% | 4.00% | Discover |
| 18-month | 4.00% | 3.90% | Discover |
| 2-year | 3.75% | 3.60% | Discover |
| 3-year | 3.50% | 3.50% | Tie |
| 5-year | 3.30% | 3.30% | Tie |
Discover has a slight edge on medium-term CDs (12-24 months). Both are competitive.
CD Minimums and Penalties
| Feature | Discover | Capital One |
|---|---|---|
| Minimum to open CD | $2,500 | $0 |
| Early withdrawal penalty (12-mo) | 6 months interest | 3 months interest |
| Early withdrawal penalty (5-year) | 18 months interest | 6 months interest |
| No-penalty CD option | ✗ | ✗ |
Capital One has lower CD minimums ($0 vs $2,500) and lower early withdrawal penalties. If you might need to break a CD early, Capital One’s terms are more forgiving.
Money Market Comparison
| Feature | Discover Money Market | Capital One 360 Money Market |
|---|---|---|
| APY | 3.90%-4.00% | 3.80%-3.90% |
| Check-writing | ✓ | ✓ |
| Debit card | ✓ | ✗ |
| Monthly fee | $0 | $0 |
| Minimum balance | $0 | $0 |
| Transaction limits | 6/month | 6/month |
Discover’s money market includes both checks and a debit card — more access points than Capital One’s money market.
ATM and Cash Access
| Feature | Discover | Capital One |
|---|---|---|
| Fee-free ATMs | 60,000+ | 70,000+ |
| ATM networks | Allpoint, MoneyPass, PULSE | Allpoint, Capital One |
| ATM fee reimbursement | ✗ | ✗ |
| Cash deposits | ✗ | ✓ |
| Daily ATM withdrawal limit | $510 | $1,000/day |
Capital One wins on ATM access — more ATMs, cash deposit capability, and higher daily withdrawal limits. Discover’s ATM network is still strong at 60,000+, but the inability to deposit cash is a limitation shared with many online banks.
Credit Card Ecosystem
Both are major credit card issuers, and their banking + card ecosystems integrate differently:
| Feature | Discover | Capital One |
|---|---|---|
| Top cash back card | Discover it (5% rotating categories) | SavorOne (3% dining/entertainment) |
| Travel card | ✗ | Venture (2x miles everywhere) |
| Flat-rate card | Discover it Chrome (2% gas/dining) | Quicksilver (1.5% everything) |
| Business cards | Limited | Spark, Ink line |
| Credit card ↔ bank integration | Seamless | Seamless |
| Combined rewards | ✗ | ✗ |
If credit cards are important to your financial setup, Capital One has the stronger and more diverse lineup. Discover’s cards are excellent for cash back but limited to a few options.
Customer Service
| Feature | Discover | Capital One |
|---|---|---|
| US-based service | ✓ (100% US-based) | Mixed (some outsourced) |
| Phone support | 24/7 | 24/7 |
