APY Calculator
Calculate APY (Annual Percentage Yield) using interest rate and compounding frequency.
APY Calculator – Calculate Your Annual Percentage Yield Instantly
Understanding APY (Annual Percentage Yield) is essential when comparing savings accounts, CDs, investment accounts, or any financial product that earns compound interest. Our APY Calculator helps you quickly compute the real annual return based on your interest rate and compounding frequency. Whether you're choosing between bank accounts or comparing investment options, this tool gives you the clarity you need.
⭐ What Is APY?
APY stands for Annual Percentage Yield, which measures the real rate of return earned on your money in one year with compounding interest included.
Unlike a simple interest rate, APY tells you how much your money actually grows when interest compounds:
-
Daily
-
Monthly
-
Quarterly
-
Semi-annually
-
Annually
This makes APY the best metric for comparing savings products.
⭐ APY Formula
Our calculator uses the standard APY formula:
Where:
-
r = annual interest rate (decimal)
-
n = number of compounding periods per year
-
APY = effective annual rate of return
The result shows how much you actually earn.
⭐ Compounding Options in the Calculator
You can select multiple compounding frequencies:
✔ Annually (1)
✔ Semi-Annually (2)
✔ Quarterly (4)
✔ Monthly (12)
✔ Daily (365)
Daily compounding usually gives the highest APY because interest grows more frequently.
⭐ How the APY Calculator Works
You only need to enter:
✔ Annual Interest Rate (%)
Example: 5
✔ Compounding Frequency
Example: Monthly
The calculator instantly displays:
-

This makes it simple to compare different banking and investment options.
⭐ Why APY Matters
APY helps you make smart financial decisions. It tells you:
✔ The true earnings on your savings
✔ Which bank gives higher returns
✔ Which CD or fixed deposit is better
✔ How compounding frequency affects growth
✔ Whether promotional rates are worth it
APY is more accurate than APR for savings products because APR doesn’t include compounding.
⭐ Example APY Calculation
If your interest rate is 5% and compounding happens monthly:
So the APY is 5.12%—higher than the stated 5% due to compounding.
⭐ Where APY Is Commonly Used
APY is used to compare:
-
High-yield savings accounts
-
Fixed deposits (FDs)
-
Recurring deposits
-
Money market accounts
-
Certificates of Deposit (CDs)
-
Treasury-backed savings
-
Investment apps
-
Crypto APY interest accounts
Any account that compounds interest benefits from APY calculation.
