About APY
The Annual Percentage Yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest. Unlike simple interest, APY considers how often the interest is applied to the balance, which can increase the total amount earned.

Key Differences
- APR (Annual Percentage Rate): The nominal annual rate without compounding
- APY (Annual Percentage Yield): The effective annual rate with compounding
- EAR (Effective Annual Rate): Another term for APY, showing the actual annual return
Why APY Matters
APY gives you a more accurate picture of what you'll actually earn on savings accounts, CDs, or other interest-bearing accounts. The more frequently interest is compounded, the higher the APY will be compared to the nominal APR.
When comparing accounts, always look at the APY rather than just the APR to understand which account will give you the best return on your money.
