APY Formula

APY = (1 + APR / n)n − 1

Where APR is the annual percentage rate and n is the number of compounding periods per year. More frequent compounding generally results in a higher APY.

What is APY (Annual Percentage Yield)?

Annual Percentage Yield (APY) represents the actual annual return on an investment or savings account after accounting for compound interest. Unlike APR, APY reflects how frequently interest is compounded, making it a better measure for comparing savings and investment products.

💹 True Annual Return

APY includes the effect of compound interest, giving a more accurate picture of your yearly earnings than APR alone.

🏦 Compare Financial Products

Banks and investment providers often advertise APY because it reflects the effective annual return after compounding.

APY Formula

APY = (1 + APR ÷ n)n − 1

Where APR is the Annual Percentage Rate and n represents the number of compounding periods in one year.

Future Value Formula

FV = P × (1 + APR ÷ n)n × t

Higher Value Usually Lower Usually Higher

How Compound Interest Increases APY

The more frequently interest is compounded, the higher your effective annual yield becomes. Daily compounding generally produces a slightly higher APY than monthly or yearly compounding for the same APR.
