(That leads to the observation that the unit of vol is 1/sqrt(time), normally a^(-1/2) [a=annum=year]). Black-Scholes Inputs. According to the Black-Scholes option pricing model (its Merton’s extension that accounts for dividends), there are six parameters which affect option prices: S 0 = underlying price ($$$ per share) X = strike price ($$$ per share) σ = volatility (% p.a.) r = continuously compounded risk-free interest rate (% p.a.)

In the Black-Scholes normal formula above, if you investigate the term $(F-K)N(d_1)$ in a spreadsheet, you’ll see that for small levels of volatility and maturity (try, for example, $\sigma=0.0025$, Maturity=1) it is actually quite close to $\max(0,F-K)$ – which is the intrinsic value of the call. The Black-Scholes formula helps investors and lenders to determine the best possible option for pricing. The Black Scholes Calculator uses the following formulas: C = SP e-dt N (d 1) - ST e-rt N (d 2) P = ST e-rt N (-d 2) - SP e-dt N (-d 1) d1 = ( ln (SP/ST) + (r - d + (σ2/2)) t ) / σ √t.
