Gap = (top rate − Capital One rate) × balance. Simple interest, annualized.

Why the gap exists

Capital One is a large branch-network bank with significant overhead — physical locations, ATM fleets, and broad product lines. Online high-yield savings accounts have far lower costs and pass the savings directly to depositors as higher APY. The gap is driven by competition and infrastructure, not by any difference in risk. Both account types carry identical FDIC coverage up to $250,000.
