Most savings accounts earn compound interest at a rate quoted as APY (annual percentage yield), which means you earn interest on both your deposits and the interest that’s already been added.

Quick Scoop

A savings account usually earns interest in these ways:

  • The bank sets an interest rate/APY (for example, 0.01% for a basic account or over 4–5% for some high‑yield online accounts, depending on market conditions).
  • Interest is typically compounded daily or monthly, then paid to your account monthly. This lets your balance grow faster than simple interest, because you earn interest on previous interest.
  • Most “regular” savings accounts at big traditional banks pay very low rates, while high‑yield savings accounts, often at online banks, pay much higher rates on the same kind of safe, liquid savings.

In short, a savings account generally earns compound interest at an APY set by the bank, and choosing a high‑yield account can dramatically increase how much you earn over time.
