How this works

High-yield savings accounts are ordinary FDIC-insured savings accounts, usually at online banks with no branch costs to cover. The money is just as safe and just as accessible as at a national bank — the difference is the rate. APYs move with the federal funds rate, so today's number won't hold forever, but the gap between high-yield and big-bank rates has stayed wide for years. Interest earned is taxable as ordinary income.
