# Coupon bond valuation formula By Roshan Waingankar Leave a Comment. Fixed Income Tutorials. The formula for bond pricing is basically the calculation of the present value of the probable future cash flows which comprises of the coupon payments and the par value which is the redemption amount on maturity. The rate of interest which is used to discount the future cash flows is known as the yield to maturity YTM. On the other, the bond valuation formula for deep discount bonds or zero coupon bonds can be computed simply by discounting the par value to present value which is mathematically represented as,.

Equation 1 defines the value of a bond that pays coupons on an annual basis and a principal at maturity.

The value of a bond paying a fixed coupon interest each year annual coupon payment and the principal at maturity, in turn, would be:. With the coupon payment fixed each period, the C term in Equation 1 can be factored out and the bond value can be expressed as:. Bonds, of course, differ in the frequency in which they pay coupons each year, and many bonds have maturities less than one year.

Also, when investors buy bonds they often do so at non-coupon dates. Equation 1, therefore, needs to be adjusted to take these practical factors into account. Many bonds pay coupon interest semiannually. When bonds make semiannual payments, 3 adjustments to Equation 1 are necessary: Note that the rule for valuing semiannual bonds is easily extended to valuing bonds paying interest even more frequently.

For example, to determine the value of a bond paying interest 4 times a year, we would quadruple the periods and quarter the annual coupon payment and discount rate. In general, if we let n be equal to the number of payments per year i. It is the rate with one annualized compounding. If the rate were expressed with monthly compounding, then we would earn 0. If we extend the compounding frequency to daily, then we would earn 0.

This rate that includes the reinvestment of interest or compounding is known as the effective rate. When the compounding becomes large, such as daily compounding, then we are approaching continuous compounding with the n term in the above equation becoming very large. For cases in which there is continuous compounding, the future value FV for an investment of A dollars M years from now is equal to:. After allowing for some slight rounding differences, this is the value obtained with daily compoundings.

It should be noted that most practitioners use interest rates with annual or semiannual compounding. Most of our examples, in turn, will follow that convention. However, continuous compounding is often used in mathematical derivations, and we will make some use of it when it is helpful. In general, the bond market is volatile, and fixed income securities carry interest rate risk.

As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities. Fixed income securities also carry inflation risk, liquidity risk, call risk and credit and default risks for both issuers and counterparties. Lower-quality fixed income securities involve greater risk of default or price changes due to potential changes in the credit quality of the issuer.

## Zero Coupon Bond Value

Bond valuation is the determination of the fair price of a bond. As with any security or capital investment, the theoretical fair value of a bond is the present value of the stream of cash flows it is expected to generate. Hence, the value of a bond is obtained by discounting the bond's expected cash flows to the present using an appropriate discount rate. In practice, this discount rate is often determined by reference to similar instruments, provided that such instruments exist. Various related yield-measures are then calculated for the given price. If the bond includes embedded options , the valuation is more difficult and combines option pricing with discounting.

We have provided a quick outline of what a student will need to know to understand bonds and the pricing or valuation of bonds which is the primary focus in the initial corporate finance program. More advanced finance courses will introduce students to advanced bond concepts including duration, managing bond portfolios, understanding and interpreting term structures, etc.

Bond valuation is a technique for determining the theoretical fair value of a particular bond. Bond valuation includes calculating the present value of the bond's future interest payments, also known as its cash flow, and the bond's value upon maturity, also known as its face value or par value. Because a bond's par value and interest payments are fixed, an investor uses bond valuation to determine what rate of return is required for a bond investment to be worthwhile. A bond is a debt instrument that provides a steady income stream to the investor in the form of coupon payments. At maturity date, the full face value of the bond is repaid to the bondholder. The characteristics of a regular bond include:.

Annual Market Rate is the current market rate. It is also referred to as discount rate or yield to maturity. If the market rate is greater than the coupon rate, the present value is less than the face value. If it is less than the coupon rate, the present value is greater than the face value. If the two rates are the same, the present value is the same is the face value.

### Bond valuation

You can use the bond price formula to determine the value of a bond. The issuer has to meet the interest and principal payments as they come due, or the bonds will go into default — something that can have devastating consequences for the issuer and, in the case of corporate bonds, its shareholders. When you calculate the price of a bond, you are determining the maximum price you would want to pay for the bond, based on how its coupon rate compares to the average rate most investors are currently receiving in the bond market. Due to default risk , investors may require a higher rate of return than the prevailing risk-free rate. In general, the greater the default risk on a given bond issue, the higher the required rate of return. This bond-pricing formula can be tedious to calculate because you have to add the present value of each future coupon payment. We can combine the bond price formula and the annuity model to arrive at the following formula, which requires us to also include the present value of the par value reached at maturity:. Our math shows that the bond is selling at a discount: The bond price is less than its par value because the required yield is greater than the coupon rate. In order to attract investors, the bond has to sell at a discount.

The bond price can be calculated using the present value approach. Bond valuation is the determination of the fair price of a bond. As with any security or capital investment, the theoretical fair value of a bond is the present value of the stream of cash flows it is expected to generate. In practice, this discount rate is often determined by reference to similar instruments, provided that such instruments exist. Bond Price: Bond price is the present value of coupon payments and face value paid at maturity.

## Bond Valuation: Formula, Steps & Examples

As a bond provides a contractual right to a series of future payments received at specified points of time, the price for a bond is simply the present discounted value of the future cash flows. The face value of a bond will be repaid at maturity. A coupon bond provides the face value at maturity in addition to a series of coupon payments often on a semi-annual basis until the maturity date. The coupon rate is contractually defined as a percentage of the face value. The yield to maturity is the internal rate of return an investor will earn by holding a bond to maturity and receiving its cash flows. The yield to maturity for a new investor differs from the coupon rate whenever the bond sells for a different price than its face value. Exhibit 1 provides a simple example to understand the pricing process for bonds. The next three columns provide the discounted value of these cash flows for different interest rates: This is an important point:
