Annual Percentage Yield (APY) Calculator
Calculate your savings account’s real rate of return with our APY calculator.
What is the Annual Percentage Yield (APY) Calculator & How does it work?
The Annual Percentage Yield (APY) is the effective annual rate of return taking into account the effect of compounding interest. It provides a more accurate picture of the interest earned than the nominal rate, especially for high-frequency compounding.
To calculate APY, you need to know the nominal interest rate and the number of times the interest is compounded per year. The formula for APY is:This formula accounts for the effect of compounding, showing how much more you earn in a year compared to simple interest.
To calculate APY, you need to know the nominal interest rate and the number of times the interest is compounded per year. The formula for APY is:
APY = (1 + frac{r}{n})^n – 1
r = nominal annual interest rate
n = number of compounding periods per year
n = number of compounding periods per year

Frequently Asked Questions
What is APY, and why is it important?
APY stands for Annual Percentage Yield. It shows the actual interest earned on an investment over a year, considering compounding. This gives a more accurate picture than the nominal rate.
How do I calculate APY if my interest compounds daily?
To calculate APY with daily compounding, use the formula: APY = (1 + r/365)^365 - 1, where r is your nominal annual interest rate.
Can you explain the difference between APR and APY?
APR stands for Annual Percentage Rate, which is the simple interest rate without considering compounding. APY includes the effect of compounding and thus represents the actual interest earned over a year.
How does increasing the number of compounding periods affect APY?
Increasing the number of compounding periods within a year will increase the APY, as more frequent compounding leads to higher overall returns.
What is the formula for calculating APY?
The formula for APY is: APY = (1 + r/n)^n - 1, where r is the nominal annual interest rate and n is the number of compounding periods per year.
How do I use this calculator to find my APY?
Enter your nominal interest rate and the number of times it compounds per year into the calculator. It will then compute your APY for you.
Is APY useful for all types of investments?
Yes, APY is particularly useful for savings accounts, certificates of deposit (CDs), and other interest-bearing investments where compounding occurs.
