Introduction to Percentage Decrease

While subtracting the second value from the first value, you will get the change between these two values. If the first value is less than the second value, you will get a negative value.

Decrease = First value - Second Value

Then divide this decreased value by the first value and multiply by 100, you will get the percentage decreased.

Minus Percentage = (Decrease / First value)*100%

2 Suitable Ways to Calculate Minus Percentage in Excel

Let’s assume a scenario where we have an Excel file that contains information about various types of input numbers. From our dataset, we will calculate the minus percentage by using the mathematical formula and VBA Macros also.  Here’s an overview of the dataset for our today’s task.

2. Run a VBA Code to Calculate Minus Percentage in Excel

Now I’ll show how to calculate minus percentage in Excel by using a simple VBA code. It’s very helpful for some particular moments and a time-saving way also. From our dataset, we will calculate minus percentage. Let’s follow the instructions below to calculate minus percentage!

Step 1:

  • First of all, open a Module, to do that, firstly, from your Developer tab, go to,

Developer → Visual Basic

Run a VBA Code to Calculate Minus Percentage in Excel

  • After clicking on the Visual Basic ribbon, a window named Microsoft Visual Basic for Applications – Percentage Decrease will instantly appear in front of you. From that window, we will insert a module for applying our VBA code. To do that, go to,

Insert → Module

Step 2:

  • Hence, the Percentage Decrease module pops up. In the Percentage Decrease module, write down the below VBA Code.
Sub Percentage_Decrease()
Worksheets("VBA").Range("D5").Value = "=(((B5-C5)/(B5))*100%)"
End Sub
