Bond yields refer to the different ways of expressing the value of a single bond. For any bond, the following yields can be calculated:Bond Yields

  • Nominal Yield (NY): Calculated based on the actual dollar amount of interest paid on the bond annually. For example, a $1,000 par value bond paying $90 of annual interest would have a nominal yield of 9%.
  • Current Yield (CY): Calculated based on the current market value of the bond. For example, a 9% bond currently trading at 95 has a current yield of 9.47%, calculated as 9 / 95.
  • Yield-to-maturity (YTM): YTM is the same as the internal rate of return. It reflects not only the coupon on the bond but also the difference between the purchase price and par value. For example, a 10-year 9% bond purchased at 95 would receive $90 of interest along with a $50 capital gain at maturity. The YTM of this bond would be 9.81%. The YTM cannot be calculated with a basic calculator, it can only be calculated with a spreadsheet or financial calculator.
  • Yield-to-maturity (YTC): YTC reflects the overall return on the bond if it is called away prior to maturity. For example, if a 10-year 9% bond were purchased at 95 and called away at par after 5 years, the YTC would be 10.33%. The YTC, like the YTM, must be calculated with a spreadsheet or financial calculator.

The four yields described here will always go either in ascending or descending order depending on if the bond is purchased at a discount (i.e. below par) or at a premium (i.e. above par). For a discount bond, the order will always be YTC > YTM > CY > NY. For a bond purchased at a premium, the order will always be NY > CY > YTM > YTC. Knowing these relationships is very important for FINRA qualification examinations.

Knopman Notes
Candidates should be familiar with the order of bond yields for a discount or premium bond.
Discount bond: YTC > YTM > CY > NY
Premium bond: NY > CY > YTM > YTC
