High interest savings accounts: Traditional banks in the United States still pay extremely low interest on savings accounts—often close to zero. In contrast, online banks operate with lower overhead and pass those savings to customers in the form of high interest savings accounts, often paying 10–15× higher APYs than brick-and-mortar banks.
In 2026, rising interest rates and fierce fintech competition have made online banks one of the smartest places for Americans to park emergency funds, short-term savings, and even long-term cash reserves. But not all online banks are equal. Some offer higher APYs but lack features, while others combine strong interest rates with excellent mobile apps, zero fees, and FDIC insurance.
This guide breaks down the best online banks in the USA with high interest savings, explains how they work, compares top options, and helps you choose the right bank for your financial goals.
