• APY is the actual rate of return that will be received in a year if interest is accrued.

  • Compound interest is periodically added to the total investment, increasing the balance. This means that each interest payment will be larger depending on the higher balance.
  • The more often the interest is compounded, the higher the APY will be.
  • APY has the same concept as the annual percentage rate (APR), but APR is used for loans.
  • APY for checking, savings or deposit certificates will vary by product and may be either a variable or a fixed rate.
