How to Price a Bond: An Introduction to Bond Valuation

how to calculate bond pricing

Similarly, when interest rates decrease, and the YTM decrease, the bond price will increase. This change is often measured in basis points, or hundredths of a percent. Therefore, the 30-year bond has increased 33 basis points over the past month, or 0.33%.

Bonds known as “agency bonds” are those that are issued or backed by a federal agency or a government-sponsored enterprise (GSE).

Collateralized Debt Obligation (CDOs)

Bonds are considered a lower-risk investment compared to stocks, making them a popular choice among investors seeking a stable income stream and the preservation of capital. However, the risk and return on bonds can vary widely, depending on the creditworthiness of the issuer and the bond’s duration. High-quality government bonds (such as U.S. Treasury bonds) are typically viewed as safe investments, while high-yield corporate bonds (also known as junk bonds) carry higher risk.

What Is the Relationship Between Bond Price and Bond Yield?

The offer document contains predefined quantities and share prices at the time of issuance. Additionally, the bondholder becomes a shareholder in the issuing corporation if these bonds are converted into stocks. Bond prices are typically stated as a percentage of their face value. In this example, the handle is 85, and we can tell that the bond is being sold at 85.87% of its face value.

Therefore, although you might’ve paid $1,000 for your bond when it was issued, the same bond may now be worth $980 or $1,020, depending on external factors like prevailing interest rates. If you buy a bond at issuance, the bond price is the face value of the bond, and the yield will match the coupon rate of the bond. That is, if you buy a bond that pays 1% interest for three years, that’s exactly what you’ll get. When the bond matures, its face value will be returned to you. Its value at any time in between is of no interest to you unless you want to sell it.

Callable Bonds Pricing

As in our yield to maturity calculator, this is a hard problem to do by hand. The trading price of a bond should reflect the summation of future cash flows. Let us first show how this is done in a spreadsheet program.

  1. When calculating the price or present value of a bond, it is often assumed that the bond trades or is issued on the coupon date.
  2. Investors value these bonds as straight bonds, and their market value is then calculated by adding the predicted discounted value of the equity to this price.
  3. It is normally calculated as the product of the coupon rate and the face value of the bond.
  4. Several different benchmark interest rates or securities are used to construct benchmark pricing curves.

As the payments get closer, a bondholder has to wait less time before receiving his next payment. This drives prices steadily higher before it drops again right after coupon payment. Understanding bond yields is key to understanding expected future economic activity and interest rates. That helps inform everything from stock selection to deciding when to refinance a mortgage.

Benchmark pricing curves are constructed using the yields of underlying securities with maturities from three months to 30 years. Several different benchmark interest rates or securities are used to construct benchmark pricing curves. Because there are gaps in the maturities of securities used to construct a curve, yields must be interpolated between the observable yields. Now, you’re ready to value the individual cash flows and final face value payment in order to value your bond as a whole. The choice of day-count convention affects the calculation of accrued interest and, therefore, the price of the bond when it is traded between coupon dates.

This can be important if you don’t want to actually own the bond for 30 years. If you want to hold the bond for five years, then you’d receive $30 annually for five years, and then receive that price of the bond at that time, which will depend on the current interest rates. This is why, while some long-term bonds (like government Treasury bonds) can be considered “risk-free” over their full lifetime, they will often vary a great deal in value on a year-to-year basis. A bond that pays a fixed coupon will see its price vary inversely with interest rates. This is because receiving a fixed interest rate, of say 5% is not very attractive if prevailing interest rates are 6%, and become even less desirable if rates can earn 7%. In order for that bond paying 5% to become equivalent to a new bond paying 7%, it must trade at a discounted price.
