## Excel Tutorial: How to do percentage sum in excel

Percentage sum calculation in excel can be a useful tool for various financial and analytical purposes. In this tutorial, we will explore the formula needed for percentage sum calculation and provide examples of how to use the formula in different scenarios.

### Using the appropriate formula

When it comes to calculating percentage sum in excel, the formula you need to use is:

=SUM(number1:numberN)/total * 100

This formula calculates the percentage sum of a range of numbers in relation to a total value and converts it into a percentage.

### Explain the formula needed for percentage sum calculation

Let's break down the components of the formula:

• SUM: This function adds up all the numbers in a given range.
• number1:numberN: This represents the range of numbers for which you want to calculate the percentage sum.
• total: This is the total value to which the percentage sum will be calculated.
• * 100: This part of the formula converts the result into a percentage.

### Provide examples of how to use the formula in different scenarios

Let's consider a practical example to understand how to use the formula for percentage sum calculation. Suppose you have a sales dataset with individual sales figures and you want to calculate the percentage contribution of each salesperson to the total sales.

You can use the formula as follows:

=SUM(B2:B6)/B10 * 100

Where B2:B6 represents the range of individual sales figures and B10 is the total sales value.

Another scenario where the percentage sum calculation is useful is when you want to determine the percentage growth of a series of values over time. For example, if you have monthly revenue figures and you want to calculate the percentage increase from one month to the next, the formula can be used in a similar manner.

By understanding and applying the formula for percentage sum calculation in excel, you can efficiently analyze and interpret data for various business and analytical purposes.

## Formatting the results

When working with percentages in Excel, it’s important to not only calculate the values accurately but also to present them in a clear and visually appealing manner. This not only makes it easier to understand the data but also adds a professional touch to your work.
