## Black-Scholes Parameters in Excel

I have decided to enter the strike, initial price and underlying price inputs in cells C4, C5, C6, respectively. The result will be shown in cell C8. While not necessary for a simple calculation like this one, it is a good idea to somehow graphically differentiate input and output cells, especially when you are building a more complex spreadsheet. It will make the sheet much easier to use and reduce the risk of you or someone else accidentally overwriting your formulas in the future.

It is best to do this consistently across all your spreadsheets. Personally, I always make the background of input cells where user is expected to enter values yellow and the output cells which typically contain formulas and should not be overwritten green — just my habit, you can of course use different colors, fonts, borders, or other formatting.

Now we have the cells ready and we can build the formula in cell C8, which will use the inputs in the other cells to calculate profit or loss. In general, call option value not profit or loss at expiration at a given underlying price is equal to the greater of:.

Now we need to implement this formula in Excel. It is very easy, because Excel has the MAX function, which takes a set of values separated with commas and returns the greatest of them. In our example, the formula in cell C8 will be:.

With the inputs in our example 45 and 49 , cell C8 should now be showing 4. You can test different values for the underlying price input and see how the formula works.

For any underlying price smaller than or equal to 45 it should return zero; for values greater than 45 it should return the difference between cells C6 and C4.

This is again very simple to do — we will just subtract cell C5 from the result in cell C8. The entire formula in C8 becomes:. Cell C8 should now be showing 1. You can again test different input values. For put options the logic and formula is almost the same, with just one little difference: The put option profit or loss formula in cell G8 is:. Now we have created simple payoff calculators for call and put options.

However, there are still some things we can improve or add to make our spreadsheet more useful. Furthermore, our calculator only shows profit or loss per share, while many people are actually more interested in total dollar profit or loss, especially when working with positions of multiple option contracts. Therefore, we should improve our calculations to also consider direction long or short , position size number of contracts and contract size number of shares represented by one option contract.

Learn more in the article on the SUM function. You can either copy the formula , or use the fill handle to copy the formula to adjacent cells. For example, when you copy the formula in cell B6 to C6, the formula in that cell automatically changes to update to cell references in column C. Cell references may change if they have relative references. For more information, see Copy and paste a formula to another cell or worksheet.
