Many concepts in the study of financial management involve complex equations that require manipulating and testing with varying parameters in order to understand the relationships inherent in these equations. Such is the case with the concepts of Bond Duration and Convexity that are taught in such financial management courses as "Financial Futures, Options and Swaps" and "Analysis of Fixed Income Securities" among others. This paper, in comparison to time-consuming mathematical hand calculations, includes Excel-based methods for solving both Duration and Convexity problems in just minutes. In addition, these models are also helpful in classroom settings to explain the effect of interest rate changes on bond price.
