# Percentage Formula in Excel

## What is Percentage Formula in Excel

In Excel, you can use the following formula to calculate the percentage of a number:

= (Part / Whole) * 100

Here, “Part” represents the portion you want to find the percentage of, and “Whole” represents the total or the whole amount.

For example, if you have a total sales amount in cell A1 and you want to find out what percentage a particular sale in cell B1 is of the total, you can use the formula:

= (B1 / A1) * 100

After entering this formula, the cell containing the formula will display the percentage value.

If you want to format the result as a percentage, you can use the Percentage format on the Home tab in Excel, or you can multiply the result by 100 and add the percentage symbol (“%”) at the end:

= (B1 / A1) * 100 & “%”

Remember to replace A1 and B1 with the actual cell references that correspond to your data.

### Percentage formula in excel

In Excel, you can calculate a percentage using the following formula:

= (Part / Whole) * 100

Here’s a breakdown of the components:

Part: This represents the portion of the whole for which you want to find the percentage.

Whole: This represents the total or the whole amount.

For example, suppose you have a total sales amount in cell A1 and a particular sale amount in cell B1. To find out what percentage B1 is of the total A1, you can use the formula:

= (B1 / A1) * 100

After entering this formula, the cell containing the formula will display the percentage value. If you want to format the result as a percentage, you can use the Percentage format on the Home tab in Excel.

Alternatively, you can use the built-in percentage formatting directly in the formula like this:

= B1 / A1

Then, apply the percentage formatting to the cell by selecting the cell, right-clicking, choosing “Format Cells,” and selecting the “Percentage” category.

## How to use percentage Formula in Excel

Using the percentage formula in Excel is a straightforward process. Here’s a step-by-step guide:

Method 1: Manual Calculation

In your Excel spreadsheet, enter the values for the part and the whole in separate cells.

### Example:

A1: Total Sales (Whole)  |  B1: Individual Sale (Part)

A2: 1000                 |  B2: 250

Apply the Percentage Formula:

In an empty cell where you want the result, enter the percentage formula.

### Example:

C2: = (B2 / A2) * 100

This formula calculates the percentage of the individual sale (B2) in relation to the total sales (A2).

### Press Enter:

After typing the formula, press Enter. The cell will now display the calculated percentage.

Method 2: Using Cell References

Enter the values for the part and the whole in separate cells.

### Example:

A1: Total Sales (Whole)  |  B1: Individual Sale (Part)

A2: 1000                 |  B2: 250

Apply the Percentage Formula using Cell References:

In an empty cell where you want the result, use cell references in the formula.

### Example:

C2: = (B2 / A2) * 100

This formula still calculates the percentage of the individual sale (B2) in relation to the total sales (A2).

Press Enter:

After typing the formula, press Enter. The cell will now display the calculated percentage.

Formatting as Percentage:

If you want to display the result as a percentage, you can either:

Select the cell with the result, go to the “Home” tab, and use the “Percentage” button.

Format the cell by right-clicking, selecting “Format Cells,” choosing the “Number” tab, and selecting “Percentage.”

Remember to adjust the cell references in the formula based on your specific data locations in the spreadsheet.
