Effective Annual Yield (EAY) Calculator
Enter the face value, annual coupon payment, and compounding frequency to compute Coupon Rate and Effective Annual Yield.
Effective Annual Yield (EAY) Calculator
When evaluating investments, understanding the true annual return is crucial. Nominal interest rates or coupon rates often fail to capture the real value of returns due to compounding effects. That’s where the Effective Annual Yield (EAY) comes in. Our Effective Annual Yield Calculator helps investors, students, and financial professionals calculate the EAY and coupon rate quickly and accurately, based on face value, coupon payment, and compounding frequency.
🔎 What is Effective Annual Yield (EAY)?
Effective Annual Yield (EAY), also known as the Effective Annual Rate (EAR), represents the actual return on an investment after accounting for compounding within the year. It provides a clearer picture than the nominal or stated rate because it reflects how often interest is applied.
👉 Formula for EAY:EAY = (1 + (i ÷ n))^n – 1
Where:
• i = Nominal annual interest rate (or coupon rate)
• n = Number of compounding periods per year
🔎 What is the Coupon Rate?
The Coupon Rate is the fixed interest rate paid annually on a bond’s face value. While useful, it doesn’t reflect the actual return if compounding is more frequent than once a year. That’s why EAY is a more accurate indicator of performance.

📚 Examples of Effective Annual Yield with Different Compounding
Annual Compounding
Face Value: 12,000
Annual Coupon Payment: 400
Frequency: Annually (1/yr)
Coupon Rate = (400 ÷ 12,000) × 100 = 3.33%
EAY = (1 + 0.0333 ÷ 1)^1 – 1 = 3.39%
✅ Coupon Rate = 3.33% , Effective Annual Yield (EAY) = 3.39%Semi-Annual Compounding (2/yr)
Face Value: $8,000
Annual Coupon Payment: $400
Coupon Rate = (400 ÷ 8,000) × 100 = 5%
EAY = (1 + 0.05 ÷ 2)^2 – 1 = 5.06%
✅ Coupon Rate = 5% , Effective Annual Yield (EAY) = 5.06%Monthly Compounding (12/yr)
Face Value: $15,000
Annual Coupon Payment: $900
Coupon Rate = (900 ÷ 15,000) × 100 = 6%
EAY = (1 + 0.06 ÷ 12)^12 – 1 = 6.17%
✅ Coupon Rate = 6% , Effective Annual Yield (EAY) = 6.17%Daily Compounding (365/yr)
Face Value: $5,000
Annual Coupon Payment: $250
Coupon Rate = (250 ÷ 5,000) × 100 = 5%
EAY = (1 + 0.05 ÷ 365)^365 – 1 = 5.13%
✅ Coupon Rate = 5% , Effective Annual Yield (EAY) = 5.13%✨ Features of Our EAY Calculator
