Program: BSF By: David Billigmeier What this program does is determines the exact value of the yield rate on a bond given Face Value (F), Redemption value (C), Present Value (P), coupon rate (r) and number of years (n). HOW TO USE: Start the program and enter in all of the inputs (F,r,P,C, and n). The program will now tell you a very rough estimate of the yield rate (i) using a very well known formula called the Bond Salesman Formula (BSF). The next prompt will tell you to enter your next guess for i. You have 2 options here. You can either enter "e" (2nd->divide symbol) which will determine the exact value automatically, or you can keep entering guesses. With each enter of those guesses you will get a better estimate for i. Doing it this way is good on tests, because it will show you all the steps. Feel free to modify this program to better fit your needs, open it up and check it out. Feel free to contact me with any questions.
