Using the Program

The two bottom cells give the user more control over the calculations. If the riskless interest is not defined as continuous compounding, then you select yes to convert the interest rate into continuous compounding. Finally, the user can define how many points to use in estimating the integral of the normal probability distribution. The default value is 50, which is a good trade off between speed and accuracy.

The following arithmetic operations can be inserted into any of the cells

  • Addition is +
  • Subtraction is -
  • Multiplication is *
  • Division is /
  • For example, entering 1000-10*10 into the amount of the loan results in 900.
