![]() ![]() If you don't understand why, see detailed explanation and examples in Call Option Payoff Diagram, Formula and Logic. underlying price minus strike price (if the option expires in the money).In general, call option value (not profit or loss) at expiration at a given underlying price is equal to the greater of: 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. 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. ![]() It is best to do this consistently across all your spreadsheets. It will make the sheet much easier to use and reduce the risk of you or someone else accidentally overwriting formulas in the future. 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 building a more complex spreadsheet. I have decided to enter the strike, initial price and underlying price inputs in cells C4, C5, C6, respectively. In an Excel spreadsheet, we first need to set up three cells where we will enter the inputs, and another cell which will show the output. The output is the profit or loss that we want to calculate. Underlying price for which we want to calculate the profit or loss = 49.Initial price for which we have bought the option = 2.35.In the above example you can identify several inputs that our payoff formula will take – they are the numbers we already know: What will my profit or loss be if the underlying ends up at $49 at expiration? Payoff Formula Inputs and Outputs I have bought a $45 strike call option for $2.35. Understanding Option Payoff Formulasīefore we start building the actual formulas in Excel, let's make sure we understand what an option payoff formula is: It is a function that calculates how much money we make or lose at a particular underlying price.įor example, it answers the following question: This is the basic building block that will allow us to calculate profit or loss for positions composed of multiple options, draw payoff diagrams in Excel, and calculate risk-reward ratios and break-even points. In this part we will learn how to calculate single option ( call or put) profit or loss for a given underlying price. This is the first part of the Option Payoff Excel Tutorial.
