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 decreased 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.
Percentage Decreased = (Decrease / First value)*100%
2 Suitable Ways to Calculate Percentage Decrease 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 percentage decrease by using the mathematical formula and VBA Macros also. Here’s an overview of the dataset for our today’s task.
1. Use Mathematical Formula to Calculate Percentage Decrease in Excel
We can easily calculate the percentage decrease by using the mathematical formula in excel. This is a time-saving way also. From our dataset, we will calculate the percentage decrease. Let’s follow the instructions below to calculate the percentage decrease!
- First of all, select cell D5.
- Hence, write down the below mathematical formula in the selected cell. The mathematical formula is,
- Further, press ENTER on your keyboard and you will get -20 as the difference of the two values.
- After that, select cell E5 and type a new mathematical formula. The formula is,
- After typing the mathematical formula, again press ENTER on your keyboard. As a result, you will get -0.40 as the output of the mathematical formula.
- we will conver the fraction value into percentage. To do that, from your Home tab, go to,
Home → Number → Percentage
- Finally, you will get your desired output in cell E5 which has been given in the below screenshot.

Now I’ll show how to calculate percentage decrease 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 percentage decrease. Let’s follow the instructions below to calculate the percentage decrease!
- First of all, open a Module, to do that, firstly, from your Developer tab, go to,
Developer → Visual Basic
- 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
- 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
- Further, run the VBA To do that, go to,
Run → Run Sub/UserForm
- After running the code, go back to your worksheet, you will be able to calculate the percentage decreased which has been given in the below screenshot.
