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.

Discover it Cash Back $480-$720 (doubled) 5% categories + 1% doubled via Match

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.
