An investor is comparing two savings accounts. Account X offers an APR of 12% with monthly compounding. Account Y offers an APR of 12.5% with annual compounding.

Which account provides a higher effective return?

  1. Both are identical because the difference between 12% and 12.5% is offset by the 12 periods.
  2. Account X, because its EAR is 12.68%.
  3. Account X, because monthly compounding always doubles the nominal rate over time.
  4. Account Y, because 12.5% is numerically higher than 12%.
