This is part 5 of the Option Payoff Excel Tutorial , which will demonstrate how to draw an option strategy payoff diagram in Excel.

One decision we need to make is the range of underlying prices that our diagram will cover. We will make the underlying price range easy to change by setting up two cells for user input — chart start in cell I5 and chart increment in cell I6, as the screenshot below shows. The formula in cell B13 is:. This will enable us to copy the formula from cell B13 to the cells below it.

Each subsequent row will show underlying price higher than the previous one, with the increment set in cell I6. Copy cell B13 to 48 following rows — cells B14 to B Then test your formulas by changing the chart settings in cells I5-I6 and make sure column B is showing the underlying prices that you expect.

For example, this is chart start set to 10 and increment set to 2. Now we have X-axis ready and can calculate the payoff at each point. Of course, the formulas in all rows will be the same — we will create them in the first row row 12 and then copy them to the other rows. We can use the formulas which we already have in rows 8 and 9, but will have to make a few adjustments. Now we can copy the formula that we have created in cell C12 to all other cells in the CF61 range.

Now we can just create a standard line chart with values range GG61 and labels range BB It will show the payoff diagram for our strategy. We can control the underlying price range effectively zoom in or out by changing the chart settings in cells I5-I6.

We can also display payoff diagrams for individual legs — in such case the chart series value range will be CC61, DD61 etc. There is of course plenty of room for improvement in terms of layout and visual design — you can change the colors or locations of different parts to adjust the spreadsheet to your preferences, you can make the chart bigger and more prominent etc.

In next two parts of the tutorial, we will look at the calculation of maximum profit, maximum loss and risk-reward ratio.

Drawing Option Payoff Diagrams in Excel. Underlying Price Range One decision we need to make is the range of underlying prices that our diagram will cover. The formula in cell B13 is: Notice the dollar sign absolute reference before the B, but no dollar sign relative reference before the When we copy the formula to other cells, this will make the formulas in the other columns C, D, E still point to column B, but each row will use its own underlying price input.

For similar reasons, we must adjust the references to cells C3, C4, C5 and place dollar signs this time before the row number, but not before the column letter.

It is just like the end of the formula in cell C9, but this time without the ABS, because we also need the direction. Make sure you get the dollar signs right. Next Steps There is of course plenty of room for improvement in terms of layout and visual design — you can change the colors or locations of different parts to adjust the spreadsheet to your preferences, you can make the chart bigger and more prominent etc.
