Coupon rate refers to the annual rate of interest earned by an investor for a bond held. As mentioned above, coupon rate is required to calculate the yield to maturity of a bond investment. When buying a new bond and planning to keep it until maturity, the shifting of prices, interest rates, and yields, will generally not affect you, except if the bond is called.
In the final part of our bond rate of return analysis exercise in Excel, the only remaining step is to convert our semi-annual YTM to an annual percentage rate, i.e. the annualized yield to maturity (YTM). In comparison, the current yield on a bond is the annual coupon income divided by the current price of the bond security. The yield to maturity is effectively a “guesstimate” of the average return over the bond’s remaining lifespan.

As such, yield to maturity can be a critical component of bond valuation. A single discount rate applies to all as-yet-unearned interest payments. Yield to Maturity is also known as a booking yield or redemption yield.
The yield to maturity of a bond depends upon the market’s current price of the bond. However, the yield-to-maturity formula proves to be a more effective yield of the bond based on compounding against the simple yield calculated with the help of the dividend yield formula. While the coupon rate of a bond is fixed, the par or face value may change. No matter what price the bond trades for, the interest payments will always be $20 per year.
Yield to Maturity Calculation Example (YTM)
The major alternative to coupon rate is what is known as a “zero-coupon bond.” In this case, the issuer does not make annual payments. At maturity, the bond holder redeems the bond for its entire par value. The note’s rate of return is the difference between its sale price and its price at maturity. The difference is that it uses the years until callable rather than the years until maturity, which shortens the time the bond is potentially held.
- This difference in yield is known as the risk premium (aka default premium), and how the risk premium varies across different bonds and different maturities is known as the risk structure of interest rates.
- They have no coupons, and they don’t pay interest at a periodic, fixed rate.
- Nonetheless, the yield of the zero coupon bond is the annualized return, which allows it to be compared to coupon bonds.
- Coupons are generally measured in terms of coupon rate, calculated by dividing it by the face value.
Because interest rates fluctuate and can change significantly over time, it is important to understand how these changes will impact bond values. Let’s say you are considering buying a bond, but you want to calculate the YTM to determine if it will meet your overall return requirements. Some facts you have on the bond are that it has a $1,000 face value and that it matures in 12 years. Assume that the current price of the bond is $675 and it pays coupons annually at 3.5%. Let’s say you own an older bond—one that was originally a 10-year bond when you bought it five years ago. When you sell it, your bond will be competing on the market with new bonds with a 5‑year maturity, since there are five years left until the bond matures.
Holding bonds vs. trading bonds
When a person buys a bond, the bond issuer promises to make periodic payments to the bondholder, based on the principal amount of the bond, at the coupon rate indicated in the issued certificate. The issuer makes periodic interest payments until maturity when the bondholder’s initial investment – the face value (or “par value”) of the bond – is returned to the bondholder. Any fixed income security sold or redeemed prior to maturity may be subject to a substantial gain or loss. Your ability to sell a CD on the secondary market is subject to market conditions. If your CD has a step rate, the interest rate may be higher or lower than prevailing market rates. If your CD has a call provision, which many step-rate CDs do, the decision to call the CD is at the issuer’s sole discretion.
High-yield bonds (“junk bonds”) are a type of corporate bond with low credit ratings. If the rating is low—”below investment grade”—the bond may have a high yield but it Yield to Maturity vs. Coupon Rate will also have a risk level more like a stock. On the other hand, if the bond’s rating is very high, you can be relatively certain you’ll receive the promised payments.
It knows it can earn an additional $1,000,000 per year from this investment for the next 10 years, the useful lifespan of the equipment, or it could choose to use that capital elsewhere and obtain a 10% return. Using a calculator, we see that the IRR of this investment would by approximately 15.1%, which is greater than the 10% required rate of return. The yield to worst is the term used to describe the lowest possible yield from purchasing a bond apart from the company defaulting. In some cases, CDs may be purchased on the secondary market at a price that reflects a premium to their principal value.
