What Is a Coupon Rate?

A coupon rate is the nominal yield paid by a 澳洲幸运5官方开奖结果体彩网:fixed-income security, such as a bond. It is the annual coupon payments paid by the issuer relative to the bond's face or par value. A coupon refers to the annual interest rate paid on a bond, paid from the issue date until maturity.

Understanding Coupon Rates

The coupon rate, or coupon payment, is the 澳洲幸运5官方开奖结果体彩网:nominal yield the bond is stated to pay on its issue date. This yield changes as the 澳洲幸运5官方开奖结果体彩网:value of the bond changes, thus giving the bond's 澳洲幸运5官方开奖结果体彩网:yield to maturity (YTM).

The coupon rate is the interest rate paid on a bond by its issuer for the term of the security. The term "coupon" is derived from the historical use of actual coupons for periodic interest payment collections. Once set at the issuance date, a bond's coupon rate remains unchanged, and holders of the bond receive fixed interest payments at a predetermined time or frequency.

A bond issuer decides on the coupon rate based on prevalent market 澳洲幸运5官方开奖结果体彩网:interest rates, among other factors, aꦿt the time of the issuance. Market interest rates change over time, and as they move lower or higher than a bond's coupon rate, the value of the bond increases or decreases🍒, respectively.

Changing market interest rates affect bond values. Since a bond's coupon rate is fixed throughout the bond's lifetime, a bondholder is stuck with receiving comparably low interest payments if the market is offering a higher interest rate. An equally undesirable alternative is selling the bond for less than its face value. Thus, bonds with higher coupon rates provide a margin of safety against rising market interest rates.

Coupon Rate Formula

A bond's coupon rate can be calculated by taking the sum of the security's annual coupon payments and dividing them by the bond's par value, then multiply🃏ing by 100 in order to be represented as a percent. The formula for coupon rate can be represented as:

Coupon Rate = (Sum of annual coupon payments / Par value) x 100

For example, a bond issued with a 澳洲幸运5官方开奖结果体彩网:face value of $1,000 that pays a $25 coupon semiannually has a coupon rate of 5%. All else held equal, bonds with higher coupon rates are more desirable for investors than those with lower coupon rates. Excel software is also 澳洲幸运5官方开奖结果体彩网:helpful for quickly calculating the bond's coupon rate.

Coupon Rate vs. Yield

When investors buy a bond initially at face value and then hold the bond to maturity, the interest they earn on the bond is based on the coupon rate set at issuance. For investors acquiring the bond on the secondary market, depending on the prices they pay, the return they earn from the bond's interest payments may be higher or lower than the bond's coupon rate. This is the effective return called yield to maturity (YTM). Another way to express this is that the current 澳洲幸运5官方开奖结果体彩网:yield of a bond i▨s t💮he annual coupon payment divided by the current price of the bond.

For example, a bond with a par value of $100 but traded at $90 gives the buyer a yield to maturity higher than the coupon rate. Conversely, a bond with a par value of $100 but tr♔aded at $110 gives the buyer a yield to maturity lower than the coupon rate.

Example of Coupon Rates

Consider a scenario in which a bond has a par value of $100 and a coupon 🐼rate of 3%. This bond provides an annual interest payment t🐭otaling $3.

If an investor purchases that bond on the secondary market for $90, she willꦛ still receive the same $3 in interest payments over a year. The current yield is thus 3.33%. If a second investor purchases the same bond for $110, h🌸e will also receive the same $3 in annual interest payments. The current yield of the bond changes again because of the new price, becoming 2.73%.

Explain Like I'm Five

A coupon is an interest payment that a bondholder receives until the bond matures. The coupon rate represents those interest payments as a percentage: If a $200 bond has a coupon rat🔴e of 3%, then the bondholder expects to receive $6 every year until the bond matures.

A bond's coupon rate is fixed when the bond is issued, but the interest rates on other bonds fluctuate according to market conditions. This means that the resale value of a bond will change according to prevailing interest rates. If market rates are low, the resale value of a bond with a high coupon rate will be very high. If market rates are high, the resale value of a bond with a low coupon will be even lower.

The Bottom Line

The coupon rate refers to the interest rate paid on a bond by its issuer for the term of the security. Bond issuers set the coupon rate based on market interest rates at the time of issuance. A bond's coupon rate remains unchanged through maturity, and bondholders receive fixed interest payments at a predetermined frequency.

As market interest rates change over time, the resale value of the bond changes to reflect the relative attractiveness of the coupon rate. While the coupon rate stays constant, the bond's yield to maturity (YTM) varies depending on its market value and how many payments remain.
