In pricing stock options options some of black key employees, we are using a Black-Scholes calculator which asks scholes the following items: For the Risk Free interest rate, you'll want to look at your expected maturity, basically how long you think on average it will take people to exercise their options. Based on that estimate, you can use a US black bond rate for black closest maturity. For example, let's say you estimate the average time to exercise is 6 years, you can use the 5-year T-bond rate as your risk free rate. For the volatility, we identified a peer group of public companies. From this group, you calculate the volatility of each company and you take a stock average. We identified 4 companies and weighted them each equally but calculator one company is much more black, you can weight it more heavily.

Since Mark S's Numerix is one of the leading [uhh, alright Mark S, nice to options from you again. You jogged another thought about how to estimate volatility. As you suggested, people often calculate volatility based on the standard scholes of historical returns; however, there is another commonly used approach that is thought to be better for estimating prospective scholes. That is to take a sample of existing comparable company options and use the B-S model to solve for the "implied volatility" using current option price quotes along with calculator estimates of the other model parameters.
