The annuity consisting of the semiannual interest payments will be discounted by the current market interest rate (the rate an investor desires). The lump sum at maturity is a single payment and that too will be discounted by the same market rate used to discount the interest payments. The resulting present value of the lump sum plus the present value of the interest annuity will be the present value and the market value of the bond. Yield to Maturity (YTM) – This can be described as the rate of return that the purchaser of a bond will get if the investor holds the bond till its maturity.
Also, this could be the prevailing interest rate to calculate the current market price of the bond. It is possible that 2 bonds having the same face value and the same yield to maturity nevertheless offer different interest payments.
The ratings vary from AAA (highest credit rating) to D (junk bonds) and based on the rating the yield to maturity varies. The higher rated bonds will offer a lower yield to maturity. Bonds which are traded a lot and will have a higher price than bonds that are rarely traded. Time for next payment is used for coupon payments which use the dirty pricing theory for bonds.
The companies or government entities that issue the bonds periodically make interest payments to investors; in Rebekah’s case, this will be once a year. The companies or government entities also agree to pay back investors the face value of the bond once it reaches maturity, like Rebekah promising to return Steve’s $1000 after three years. If the investor sold the bond, the return received by the previous owner is defined in terms of any coupon payments received less the capital loss associated with the interest rate rise. This is the explanation for why increasing interest rates lower the prices for existing bonds. The semiannual interest payments are considered an annuity, since the bond’s stated interest rate and the resulting interest payments do not change even though the market rates are changing each hour.
Bond valuation includes calculating the present value of a 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. But bonds can be sold and resold on secondary markets prior to the maturity date. If I pay $900 for a bond providing a fixed set of promised payments, then I’m going to get a higher return on my $900 investment than if I paid $1,100 for the same set of promised payments. Lower ask prices imply higher yields, and vice versa.
The current yield is simpler measure of the rate of return to a bond than the yield to maturity. Current yield is measured as the ratio of the bond’s annual coupon payment to the bond’s market price. Generally, if you are pricing a bond, it is because you are considering buying or selling it. In either case, there are certain terms of the bond that you will know.
Understanding Bond Valuation
The second buyer will get a higher yield than you because he or she paid less for the bond, but the buyer will still get its full par value when it matures. A bond is a security with a fixed cash flow per period, C, and a balloon payment, F, at the end of the bond’s life. The periodic $C cash flow is called a coupon, and the single $F payment is called the bond’s face value. The bond’s life is called the bond maturity, and the coupon payment is usually made every six months.
Bond pricing formula depends on factors such as a coupon, yield to maturity, par value and tenor. These factors are used to calculate the price of the bond in the primary market. In the secondary market, other factors come into play such as creditworthiness of issuing firm, liquidity and time for next coupon payments. Bond valuation is a technique for determining the theoretical fair value of a particular bond.
But investors don’t have to buy bonds directly from the issuer and hold them until maturity; instead, bonds can be bought from and sold to other investors on what’s called the secondary market. Similar to stock, bond prices can be higher or lower than the face value of the bond because of the current economic environment and the financial health of the issuer.
Clean bond prices are prices without accrued interest; dirty bond prices include accrued interest. Bond valuation, in effect, is calculating the present value of a bond’s expected future coupon payments.
- When a bond is first issued, it is generally sold at par, which is the face value of the bond.
- Sometimes when the demand is higher or lower than an issuer expected, the bonds might sell higher or lower than par.
The ratio of the total coupon payments per year (2C in this case) to the face value is called the coupon rate. We can use the formulas generated earlier to price different kinds of bonds, once we know the appropriate interest rate. (This method may not give the right answer if the bond is not actually priced close to par). Bonds issued by government or corporates are rated by rating agencies like S&P, Moody’s, etc. based on the creditworthiness of issuing firm.

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. 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 selling price or the market value of a bond is the present value of the future cash derived from the bond.
When a bond is first issued, it is generally sold at par, which is the face value of the bond. Most corporate bonds, for instance, have a face and par value of $1,000.
That’s because their coupon rates may not be the same. If you buy a new bond and plan to keep it to maturity, changing prices, market interest rates, and yields typically do not affect you, unless the bond is called.
Note that the bond price steadily increases each day until reaching a peak the day before an interest payment, then drops back to the flat price on the day of the payment. When you actually buy a bond on the secondary market, you would have to pay the former owner of the bond the accrued interest. If this were not so, you could make a fortune buying bonds right before they paid interest then selling them afterward. Because the interest accrues every day, the bond price increases accordingly until the interest payment date, when it drops to its flat price, then starts accruing interest again.
Sometimes when the demand is higher or lower than an issuer expected, the bonds might sell higher or lower than par. In the secondary market, bond prices are almost always different from par, because interest rates change continuously. When interest rates rise, bond prices decline, and vice versa. Bond prices will also include accrued interest, which is the interest earned between coupon payment dates.
It takes into account the price of a bond, par value, coupon rate, and time to maturity. When you buy a bond on the secondary market, you are probably going to pay a price above or below the par of the bond. This will affect your yield-to-maturity, a calculation based on the bond’s original purchase price, redemption value, time to maturity, coupon rate, and the time between interest payments. For example, if you buy a bond and then sell it after interest rates have risen, you will get a lower price for the bond than what you originally paid for it.
In other words, the semiannual interest payments and the payment of the face value of the bond at its maturity date will be discounted by the market interest rate. The resulting present value of those two amounts is the market value. The reality is that $1,000 in 30 years is not as valuable as $1,000 next year, nor is it as valuable as $1,000 in your hand right now. A bond is a loan an investor makes to a company or government for a set period of time and an agreed upon interest rate.
The dirty price of a bond is coupon payment plus accrued interest over the period. between payments Graph of the purchase price of a bond over 2 years, which is equal to the flat price + accrued interest. The accrued interest must be calculated according to the above formula.
The theoretical fair value of a bond is calculated by discounting the present value of its coupon payments by an appropriate discount rate. The discount rate used is the yield to maturity, which is the rate of return that an investor will get if s/he reinvested every coupon payment from the bond at a fixed interest rate until the bond matures.
