How to Insert the Delta Symbol Δ in Excel in a Cell

30+ Advanced Excel Tips for 2026

No spam. Only Excel Stuff. God Promise. 😊

Go to Insert → Symbol, set Subset to Greek and Coptic, select Δ and click Insert. For a formula, use =UNICHAR(916). It returns Δ in any font and needs Excel 2013 or later.

For the triangle arrows used in variance reports, change the code: =UNICHAR(9650) gives ▲ and =UNICHAR(9660) gives ▼. Use 9651 and 9661 for the outlined △ and ▽.

To show Δ beside a number and keep it a number, press Ctrl + 1, choose Custom and enter 0.0%" Δ". For a change column, [Color10]"▲ "0.0%;[Red]"▼ "0.0%;0.0% shows a green ▲ on increases and a red ▼ on decreases. The value still works in sums and charts.

The older tricks are typing D and switching the font to Symbol, or =CHAR(114) in Wingdings 3. Both depend on the font, so the symbol turns back into a letter when the font changes or the cell is copied into another file. UNICHAR doesn’t have that problem.

Anything that adds Δ to the value itself turns the number into text that won’t total or sort as a number. That includes =B2&" "&UNICHAR(916), pasting, AutoCorrect and a macro. Use the custom format whenever the cell still needs to calculate. If UNICHAR returns #NAME?, you’re on Excel 2010 or earlier, so use Insert → Symbol instead.

Change the Font to Symbol to Get Delta

I found this to be the quickest way to add a delta symbol, and it’s pretty simple. All you have to do is:

  1. First of all, enter “D” in the cell (Capital Letter) where you want to insert the symbol.
    enter delta symbol in excel using font style
  2. After that, change the font style to “Symbol” from the Home Tab > Font > Font Name.
    enter delta symbol in excel by changing font style

This will instantly convert that “D” symbol into a delta. But one thing you need to take care of is that this will change the font style for the entire text in the cell.

Simply Insert Delta Symbol from Symbols Option

This is a simple way to insert any symbol you want to add in a cell. All you need to do is open the symbol dialog box, search for the symbol, and insert it. Here’s how to do it in steps.

  • First of all, select the cell where you want to add the symbol.
  • Then go to Insert Tab ➜ Symbols ➜ Symbol.
    go to insert tab to insert delta symbol in excel
  • Now from insert symbol window, select “Greek and Coptic” and it will navigate you to the Greek symbols.
    select greek symbols to insert delta excel
  • From here, click on the Delta symbol and click on insert.

Once you click on Insert, it will add one symbol to the selected cell, which you can copy and add further to other cells.

  1. Pros: This method is simple and easy to use.
  2. Cons: It’s not dynamic, and you have to repeat it or copy and paste the symbol into other cells.

Use the UNICHAR Function to Get Delta Symbol in a Cell Using a Formula

The CHAR function can insert a specific character by providing a code. You can use it for the Delta symbol as well; here’s how.

  • In a cell where you need to insert the symbol, enter the formula =UNICHAR(916) in Excel’s formula bar.
  • Then change the font style of that cell to “Wingdings 3”.

The above two formulas add two different delta symbols; the first one inserts a white (outlined) symbol, and the second one adds a black (filled) symbol.

  1. Pros: As CHAR is a function, this formula gives you the option to choose between two different types of symbols.
  2. Cons: If you want to add the symbol by concatenating it with some other formula, it doesn’t work because you have changed the font style.

Use the AutoCorrect Option to Automatically Add a Delta Symbol

This is another useful way to add a delta symbol. In Excel, there is an option called Auto Correct which you can use to insert a symbol by typing a simple text. All you need to do is specify a text that you use to enter in a cell, and then whenever you use that text, Excel will convert that text into a symbol. Here are the steps.

  1. First of all, copy this delta symbol from here or you can also do it by inserting the symbol from the symbol options.
  2. After that, go to File Tab ➜ Options ➜ Proofing ➜ AutoCorrect ➜ Options.
    open auto correct option to insert a delta symbol
  3. Now in the AutoCorrect dialog box, in the “Replace with” input box enter “(dlt)” and in the “With” input box paste the delta symbol which you have copied.
    add text in auto correct option for delta symbol in excel
  4. In the end, click OK.

Now, whenever you type “(dlt)” in a cell, Excel will convert that text into a delta symbol. You can even use a different text from the text that we have used here.

  1. Pros: It makes it super easy to insert a symbol by entering text. Just enter the text, and Excel converts it into a symbol.
  2. Cons: Again, this isn’t dynamic, so if you need to add the symbol again, you have to enter the text again.

Apply Custom Formatting to Add a Delta Symbol with a Number or Percentage [My Favorite]

This one is the most awesome method and my favorite one. Let’s say you want to add a delta symbol with numbers in a cell then this is the best method. When we use a custom formatting, in that case, we just need to specify the format and Excel applies it to the cell without changing the values in the cell. Follow these simple steps for this:

  • First of all, select the cell where you want to apply custom formatting with a delta symbol.
  • Now, right-click and open the format option and go to the Custom category.
    open custom formatting for delta symbol format in excel
  • From here, in the format input bar enter the below format and click OK. General Δ
    add custom format in input bar with delta symbol excel
  • Once you apply this custom format it will show a delta sign with all the number in the cell.

In this method idea is simple, no matter which format you have just combined that format with a delta sign in the custom formatting category and you’ll get the symbol. Look at the below percentage format with a delta sign.

  • This is the best method of all the methods we have here because it doesn’t affect the values of the cell.
  • If you want to add a delta symbol to a cell for real then this method is not for you

VBA Code to Insert Delta Symbol into Multiple Cells

Macro code is a big-time time saver, and if a code can insert a delta symbol in a cell for you, then there is nothing like that. And  below we have this code:

Sub AddDeltaAsText()

    Dim cell As Range
    Dim workArea As Range
    Dim delta As String
    Dim shown As String

    'Stop if a shape or chart is selected instead of cells
    If TypeName(Selection) <> "Range" Then
        MsgBox "Select the cells first.", vbExclamation
        Exit Sub
    End If

    'Only loop through the used part of the selection
    Set workArea = Intersect(Selection, Selection.Parent.UsedRange)
    If workArea Is Nothing Then Exit Sub

    delta = ChrW(916)

    For Each cell In workArea.Cells
        shown = cell.Text   'the displayed value, so 25% stays 25%

        If IsEmpty(cell.Value) Then
            'skip blank cells
        ElseIf cell.HasFormula Then
            'skip formulas so they aren't overwritten
        ElseIf IsError(cell.Value) Then
            'skip error values
        ElseIf Right(shown, 1) = delta Then
            'skip cells that already have the symbol
        ElseIf Left(shown, 2) = "##" Then
            'skip cells too narrow to show their value
        Else
            cell.Value = shown & " " & delta
        End If
    Next cell

End Sub

To use this code, first enter it in the VB editor (open it from the Developer tab).

And then, select the cell and run the code. If a cell has a value, it adds the symbol after that value. If you have more than one cell, it loops through each cell and inserts the symbol.

  • VBA code can save you time, and you can use it with just a single click.
  • When it adds a symbol to a cell, and if that cell has a number or a percentage, it becomes a text string after that and can’t be used further in calculations.

Copy – Paste the Delta Symbol into the Cell

This is an unusual method but works if you need to insert a delta symbol in a cell for once. The idea is simply to copy the symbol from somewhere, or you can copy it here (Δ) as well, and then simply paste it into the cell.

  1. Hi,

    When we take formula =CHAR(112)/=CHAR(114) —-> then it is giving result as #VALUE! because excel wants to take formula =CHAR(112)/CHAR(114) instead of =CHAR(112)/=CHAR(114)

  2. Sir,
    Another method to add delta symbol can be a short cut and or assign it to the qat through a macro recording.

  4. Hi,
    If you right lower “r” and change theme Font to “Wingdings 3” you get the same effect.
