Definition of Coupon Rate
The Coupon Rate is the annual interest rate a bond issuer promises to pay its bondholders, expressed as a percentage of the bond’s face (par) value. It represents the fixed income earned by an investor for lending money to the issuer, usually paid semi-annually or annually.
For example, if a bond has a face value of ₹1,000 and a coupon rate of 6%, the investor will receive ₹60 per year until maturity.
Understanding Coupon Rate in Detail
In the world of bonds and fixed-income securities, the coupon rate is a crucial concept. It determines the cash flow an investor earns from holding a bond.
-
For the issuer (such as a government or corporation), the coupon rate represents the cost of borrowing money.
-
For investors, it reflects the return on investment (ROI) in the form of periodic interest payments.
Unlike the market interest rate (yield), the coupon rate is fixed at the time of issuance and does not change throughout the life of the bond. However, the bond’s market price may fluctuate, which affects its yield to maturity (YTM), not the coupon rate.

Difference Between Coupon Rate and Yield
-
Coupon Rate: Fixed annual interest rate based on face value.
-
Yield: Actual return an investor earns, based on the bond’s purchase price and coupon payments.
Relationship with Market Interest Rates
-
When market interest rates rise, bond prices fall, making older bonds with lower coupon rates less attractive.
-
When market rates fall, older bonds with higher coupon rates become more valuable.
Formula for Coupon Rate
Example Calculation
Suppose a corporate bond has:
-
Face Value = ₹10,000
-
Annual Coupon Payment = ₹800
Thus, the bond pays an 8% coupon rate annually.
Is Coupon Rate an Accounting Term?
The coupon rate itself is a financial and investment concept rather than a direct accounting term. However, interest payments arising from bonds do impact accounting records.

Key Features and Components of Coupon Rate
-
Fixed Nature: Remains constant for the life of the bond.

-
Payment Frequency: Typically semi-annual or annual.

Case Study Example
Government Securities in India
The Reserve Bank of India (RBI) issues government securities (G-Secs) with fixed coupon rates. For example:
-
A 10-year G-Sec with a coupon rate of 7% on ₹1,00,000 face value will pay ₹7,000 annually.
-
Even if market interest rates change, the coupon payment remains constant.
This gives investors stability and predictable returns.
Practical Example
A company issues bonds:
-
Face Value = ₹50,000
-
Coupon Rate = 9%
-
Investor holds 10 such bonds.
Annual income = 50,000 × 9% × 10 = ₹45,000
Common Mistakes and Misunderstandings
-
Confusing coupon rate with yield. Yield changes with market price, coupon does not.
-
Assuming coupon rate is based on market value instead of face value.
-
Overlooking inflation, which reduces the real return of fixed coupon bonds.
Real-Life Applications and Legal Implications
-
Corporate Financing: Companies use bonds with competitive coupon rates to raise debt capital.
-
Government Borrowing: Governments issue treasury bonds and G-Secs with fixed coupons.
-
Regulatory Compliance: Issuers must disclose coupon rates in bond prospectuses under SEBI/RBI guidelines in India.
-
Retirement Planning: Fixed coupon bonds are popular among retirees for predictable income.

Expert Tip from Learn with Manika
When analyzing bonds, never look at the coupon rate alone. Always compare it with current market yields, inflation, and issuer’s credit rating. This ensures you invest in bonds that provide not just fixed income but also real value growth.
