What Is APY?
APY tells you what you actually earn on savings, while the stated rate tells you the base calculation. Always compare APY when shopping for savings accounts.
About This Calculator
APY (Annual Percentage Yield) is the yearly return on savings including the effect of compounding. It is always slightly higher than the stated interest rate because interest earns interest.
Real-world example: A savings account paying 4.88% interest compounded monthly has a 5.00% APY — the compounding boost shows up in the APY.
