Coupon Rate
The annual interest rate payable on a bond, expressed as a percentage of its face value. A bond with a face value of PKR 1,000 and a 10% coupon rate pays PKR 100 in interest per year.
01—What is Coupon Rate?
The definition — and what it means in practice.
Coupon rate is the annual interest rate a bond promises to pay, stated as a percentage of the bond’s face value (par value). It describes the size of the bond’s regular interest payments, not the return you will necessarily earn. For example, a bond with a face value of Rs 1,000 and a 10% coupon rate pays Rs 100 of coupon interest per year, usually in periodic instalments.
Coupon rate matters because it helps you estimate the cash income a bond can generate and compare different fixed-income securities on a like-for-like basis. However, the coupon rate is fixed at issuance, while the bond’s market price can change. If you buy above or below face value, your realised return (yield) will differ from the coupon rate. Taxes, reinvestment of coupons, and default risk also affect outcomes.
A 10% coupon on a Rs 1,000 bond means Rs 100 interest each year, even if you paid more or less than Rs 1,000 for it.
Annual Coupon Payment = Coupon Rate × Face Value
Coupon rate is a percentage per year; face value is the bond’s par amount (e.g., Rs 1,000).
- Coupon rate is stated on face value, not on the price you pay in the market.
- It determines the bond’s promised interest cash flows (subject to issuer paying).
- Coupon rate is different from current yield and yield to maturity.
- Buying at a premium or discount changes your effective return, not the coupon rate.
- Payment frequency can vary; the annual coupon is often split into periodic payments.
02—How coupon rate works on the PSX
The Pakistan-specific rules, conventions, and numbers.
For a Pakistan investor, coupon rate is most often encountered when comparing government securities such as Treasury Bills (T-Bills) and Pakistan Investment Bonds (PIBs), or corporate debt instruments like debentures and Sukuk. The coupon rate provides a quick way to understand the instrument’s stated periodic income based on its face value, before considering the price you pay and other costs.
PSX investors may also come across coupon rate in fixed-income or balanced products that hold bonds, where disclosures often describe holdings by coupon and maturity. In practice, you will still need to separate the stated coupon from the return you earn, because market pricing, transaction costs, and holding period influence realised yield. If you are comparing instruments, pair coupon rate with yield measures rather than treating it as a total-return figure.
03—Common misconceptions
Where investors most often get this wrong.
Coupon rate is the return I will earn if I buy the bond.
Coupon rate only sets interest on face value. Your return depends on the price paid, time to maturity, and whether coupons are reinvested.
A higher coupon rate always means a better bond.
Higher coupons can come with different maturities, credit risk, or pricing. A lower-coupon bond bought cheaply may still offer a competitive yield.
Coupon rate changes when interest rates change.
For fixed-rate bonds, the coupon rate is set at issuance. Market interest-rate changes usually affect the bond’s price and yield, not its coupon.

Frequently Asked Questions
Coupon rate is the bond’s stated annual interest percentage applied to its face value. A 10% coupon on a Rs 1,000 face value bond implies Rs 100 per year in coupon interest, typically paid in scheduled instalments.
No. Coupon rate is the stated interest based on face value. Yield measures the return based on the market price you pay (and, for yield to maturity, also includes the gain or loss versus face value at maturity).
Multiply the coupon rate by the bond’s face value. Example: 10% × Rs 1,000 = Rs 100 per year. If coupons are paid more frequently, that annual amount is split across the payment dates.
Yes. Bonds can trade at a premium or discount depending on market conditions and perceived risk. The coupon rate stays the same for a fixed-rate bond, but the yield changes because the purchase price changes.
Sukuk often describe periodic distributions that resemble coupon-like cash flows. The label and structure can differ, but investors still need to distinguish the stated periodic payout rate from the return earned at the purchase price.
