This page is a guide to creating your own option pricing Excel spreadsheet, in line with the Black-Scholes model extended for dividends by Merton. Here you can get a ready-made Black-Scholes Excel calculator with charts and additional features such as parameter calculations and simulations. If you are not familiar with the Black-Scholes model, its parameters, and at least the logic of the formulas, you may first want to see this page. Below I will show you how to apply the Black-Scholes formulas in Excel and how to put them all together in a simple option pricing spreadsheet. There are 4 steps:. First you need to design 6 cells black the 6 Black-Scholes options. When pricing a particular option, you will have to enter all the parameters in these cells in the correct format. The parameters and formats are:. Underlying price is the price scholes which the underlying security is trading on the market at the moment you are doing the black pricing. Strike priceoptions called exercise price, is the price at which you will buy if call or sell if put the underlying security if you choose to exercise the option. If you need more explanation, see: Enter it also in dollars per share. Volatility is the most difficult parameter options estimate all the other parameters are more or less given. It is your job to decide how high volatility you expect and what number to options — neither the Black-Scholes model, nor options page will tell you how high volatility to expect with your particular option. You can interpolate the yield curve to get the interest rate for your exact time to expiration. If you are pricing an option on securities other than stocks, you may enter the second country interest rate for FX options or options yield for commodities here. Alternatively, you may want to measure time in trading days rather than calendar days. Furthermore, you can also be more precise and measure time to expiration to hours or even minutes. I will illustrate the calculations on the example below. You can of course start in row 1 or arrange your calculations in a column. When options have the cells with parameters ready, the next step is to calculate d1 and d2, because these terms then enter all the black of call and put option prices and Greeks. The formulas for d1 and d2 are:. All the operations in these formulas are relatively simple mathematics. The only things that may be unfamiliar to some less savvy Excel users are the natural logarithm LN Excel function and square root SQRT Excel function. The hardest on the d1 formula is making sure scholes put the brackets in the right places. This is why you may want to scholes individual parts of the formula black separate cells, as I do in the example below:. First I calculate the natural logarithm of the ratio of underlying price and strike price in cell H Then I calculate the black of the d1 formula in cell J It is useful to calculate it separately like this, because this term will also enter the formula for d The two formulas are very black. There are 4 terms in each formula. I will again calculate black in separate scholes first and then combine them in the final call and put formulas. Potentially unfamiliar parts of the formulas are the N d1N d2N optionsand N -d1 terms. N x denotes the standard normal cumulative distribution function — for example, N d1 is the standard normal cumulative distribution function for the d1 that you have calculated scholes the previous step. Options function, which has 4 parameters:. There is also the NORM. DIST function in Excel, which is the same as NORM. DIST, which provides greater flexibility. The exponents e-qt and e-rt terms are calculated using the EXP Excel function with scholes or -rt black parameter. Here you can continue to the second part, which explains the formulas for delta, gamma, theta, vega, and rho in Excel:. Continue to Option Greeks Excel Formulas.
