To display text based on another cell, you have to use the conditional function IF.
=IF(A2<51,"Bottom 50%","Top 50%")

The function displays the value in the first argument (“Bottom 50%”) if the condition is met, otherwise it displays the text “Top 50%”.
It becomes more complicated when there more conditions. Let’s say that we need more conditions:
- Bottom 25%
- Bottom 50%
- Top 50%
- Top 25%
Now our function will look like this.
=IF(A2<26,"Bottom 25%",IF(A2<51,"Bottom 50%",IF(A2>75,"Top 25%","Top 50%")))
As you can see, it becomes really complicated even for such a low number of conditions.

Instead of using this way to create a formula for more conditions, you can create a function in VBA that will display the desired text.
Add text based on a cell value in VBA
To do this we are going to use a function with the Select … Case statement. The function will take one parameter, which is a reference to a cell.
Create a new module and enter the following formula.
Function CheckValue(cell As Range)
Select Case cell
Case 1
CheckValue = "Bottom 1%"
Case 2 To 10
CheckValue = "Bottom 10%"
Case 11 To 25
CheckValue = "Bottom 25%"
Case 26 To 50
CheckValue = "Bottom 50%"
Case 51 To 75
CheckValue = "Top 50%"
Case 76 To 90
CheckValue = "Top 25%"
Case 90 To 99
CheckValue = "Top 10%"
Case 99 To 100
CheckValue = "Top 1%"
Case Else:
CheckValue = "Not in range"
End Select
End Function
Type =CheckValue(A2) into cell B2 and autofill for the rest of the cells in the column.
This is a great way to write such functions because it’s more readable and can be easily modified.
