The capital Greek letter Delta (∆) stands for difference or increment in Mathematics. In some cases, it would also help to use it in Excel: Instead of writing “Difference” or “Change”, you could simply insert the Delta sign. Here is how to do that in Windows and Mac!

## The fastest method for Windows: Professor Excel Tools

This is the fastest method: Go to the Professor Excel ribbon, click on the drop-down arrow of “Insert Symbol” and then on the delta sign ∆.

Just download and install the Excel-add-in Professor Excel Tools and see if it works for you.

## Insert Delta Sign (∆) in Windows

### Method 1 in Windows

The “traditional” way to insert the sign showing the difference in Windows is through the Insert Symbol window:

- On the Insert ribbon, click “Symbol” (the right-most button).
- In the Symbol window, select “Unicode (hex)” in the from field.
- Type 0394 into the “Character code” field. You should now see the Greek character selected above.
- Click on Insert to insert the symbol into the cell or chart.

### Method 2 in Windows

Probably not as beautiful, but it usually works: Alternatively, just copy and paste it from here.

## Insert Delta Sign (∆) in Mac

It’s almost the same in Mac OS as in Windows, but the window looks a bit different. Still, you have to go to the Insert ribbon and click on Symbol on the right-hand side:

- On the Insert ribbon, click on Symbol (on the right-hand side).
- In the Character Viewer, go to Mathematical Symbols.
- Insert the ∆ by double-clicking on it.

## Add the Greek Letter Delta to a chart

You want to show the delta sign ∆ on a chart? It works the same way as described above. The only difference: Insert a text field first.

In order to do this, select your chart. Then go to the Insert ribbon. On the right-hand side, click on the button “Text Box” and draw it onto the chart. Now, you can simply copy & paste or insert ∆ there.
