Annual Percentage Yield (APY) provides a standardized way to compare the true return on savings accounts and investments by accounting for the effects of compounding interest. Unlike the nominal interest rate, which does not consider compounding frequency, APY shows you exactly how much interest you will earn in one year. This calculator helps you make apples-to-apples comparisons between savings accounts, CDs, and other financial products that advertise different nominal rates and compounding schedules. Understanding APY is crucial for making the most of your savings.
Result: 5.00% nominal rate compounded monthly: APY = (1 + 0.05/12)^12 - 1 = 0.05116 or 5.116%. The difference (5.116% - 5.00% = 0.116%) amounts to $11.60/year on a $10,000 deposit. Daily compounding at 5%: APY = 5.127%.
