Checking Economics
$3,000 average balance, $2,000/month debit spending:
| Metric | Capital One 360 | Discover Cashback |
|---|---|---|
| Interest earned | $3.00/yr | $0 |
| Debit cashback | $0 | $240/yr |
| ATM fees | $0 | $0 |
| Monthly fees | $0 | $0 |
| Net benefit | $3/yr | $240/yr |
Winner: Discover — the 1% debit cashback is worth far more than Capital One’s 0.10% interest on checking balances. However, Discover lacks Zelle, which matters for peer payments.

|---|---|---|
| 3-month | 4.00% | 4.00% |
| 6-month | 4.20% | 4.20% |

Winner: Capital One — superior travel card ecosystem, airport lounge access, and universal international acceptance (Visa/Mastercard). Discover’s Cashback Match is excellent for the first year, and no cards have annual fees — but there are no transfer partners and limited international acceptance.
