We can also find the percentage from the value and a number. We have to just use the mathematical formula as Value divided by Number.

**Percentage = Value / Number**

For example, What is the percentage of 500 from 1000?

In the figure, we have Number as 1000, Value as 500 and we have to find out the Percentage.

**Step 1**: Select the Cell B3

**Step 2**: Write the formula as = B2/B1

**Step 3**: Press the Enter key.

**Step 4**: Result may come in Decimal if the cell is not converted to a percentage. We have to convert the cell to Percentage.

**Step 5**: Select the cell B3

**Step 6**: Under **Home** tab >> under **Number** Group >> Click on **%** button to convert the numerical value of cell into percent value.

- Result is now converted to percentage value.

**Formula of Percentage in Excel – Example # 3**

We can find the percentage of each number from the total value of the data sets. We have to just use the mathematical formula as Each Number of the Data Set divided by Sum of the total Data Set.

**Percentage of Each Number = Each Number of the Data Set / Sum of the total Data Set**

For Example, We need to find out the percentage of the Basic pay of each employee of the company.

Let us consider the example of Basic pay of the employees’ table.

**Step 1**: Select the cell A13 and Write Total Basic Pay.

**Step 2**: Select cell B13.

**Step 3**: Write the summation formula as **= Sum (B3:B12)** or **=SUM(B3,B4,B5,B6,B7,B8,B9,B10,B11,B12,)**

**Step 4**: Press Enter

**Step 5**: Result of the total basic Pay will appear.

**Step 6**: Select the cell C2 and Write Percentage.

**Step 7**: Select the cell C3

**Step 8**: Write down the formula as **=B3/$B$13**. Fix the cell B13 using **$** sign or by pressing **F4** after selecting the cell B13.

**Step 9**: Result may come in Decimal if the cell is not converted to a percentage. We have to convert the cell to Percentage.

**Step 10**: Under **Home** tab >> under **Number** Group >> Click on **%** button to convert the numerical value of cell into percent value.

**Step 11**: Select the cell C3

**Step 12**: Either copy the cell C3 and paste in the range C4: C12 or drag down the formula from C3 to C12 cell to copy the formula in all the cells with the required Percentage format.

#### Formula of Percentage in Excel – Example # 4

We can also find an increase or decrease in change in percentage between the two values. We have to just use the mathematical formula as the difference between the Numbers divided by the first number.

**Change in percentage = (2 ^{nd} Number – 1^{st} Number) * 1^{st} Number**

For example, We need to find the profit percentage on the cost price.

**Step 1**: Select the cell F2 and write the formula as **= (E2-D2)/D2**

**Step 2**: Press the Enter key.

**Step 3**: Under **Home** tab >> under **Number** Group >> Click on **%** button to convert the numerical value of cell into percent value.
