# How to Calculate Delta in Excel (2 Ideal Examples)

In this article, we will learn how to calculate delta in Excel. Delta indicates the difference between the 2 numbers. We can easily calculate delta in Excel. Also, there is DELTA function available in Excel. We will explain the use of the DELTA function in the last section. So, without any delay, let’s start the discussion.

## 2 Ideal Examples to Calculate Delta in Excel

Delta is used for calculating the difference. We will show you 2 examples of calculating Percentage Delta and Delta for Business Model. Let’s follow the steps to learn how to calculate delta in Excel.

### 1. Compute Percent Delta in Excel

To demonstrate the method we will use a dataset of a company’s sales information in 2021 and 2022. We want to know the change in sales between 2021 and 2022. We will use Percent Delta for showing the comparison of the sales of 2021 and 2022. Let’s see the steps to compute the percent delta in Excel.

STEPS:

• Firstly, select the cell where you want to put the result
• We will show our result in the %Delta column.
• Therefore, select the F5 cell and write the following formula:
`=(E5-D5)/D5` This formula mainly indicates (Sales in 2022-Sales in 2021)/ Sales in 2021.

• Secondly, press Enter and you can the result.
• After that, drag the formula from F5 to F9 cells with the help of AutoFill. • So, the values of Delta showing in the %Delta column.
• But, the result is not shown in the percentage format.
• Now, we will change the format of the cells of the column.
• So, select the cells from F5 to F9. • Now, go to the Home tab and click on the Number of the Number group from the ribbon. • As a result, a drop-down menu will open up, and select Percentage from there.
• So, the numbers will be converted into percentage format. • Finally, we have been able to calculate Percent Delta in Excel. ### 2. Calculate Delta for Business Model in Excel

To demonstrate the example, we will use a dataset of a company’s condition in the Stock Market. We have observed the company’s Option price and the Underlying stock on the 1st and 31st of October 2022. So, we will calculate the delta to show the comparison of stock market conditions between the 1st and 31st of October. According to the business model, Delta is the ratio of the difference between the Option Price and the Underlying Stock of the company. Let’s see the steps to calculate the delta in Excel.

STEPS:

• Firstly, select the C8 cell and write the following formula:
`=(C5-C4)/(C7-C6)` This formula mainly indicates (Final- Initial Option Value)/(Final-Initial Underlying Value).

• Now, press Enter.
• So, you can see the value of Delta in the C8 cell. ## How to Use DELTA Function in Excel

In this section, we will show the use of the DELTA function. To demonstrate the method, we will use a dataset containing age information from a group of children. A renowned theatre group is looking for a 7-year-old child. Using the DELTA function, they can easily solve the problem from this dataset. • Summary

This function compares 2 numbers. Then, it returns 1 if the numbers are equal and returns 0 if the numbers do not match.

• Syntax

The syntax of the DELTA function is given below:

`=DELTA(number1,[number2])`
• Arguments

Here, number1 is required and number2 is an optional argument. Put the 2 numbers you want to compare as number1 and number2 arguments.

Let’s see the steps to know how to use the DELTA function in Excel.

STEPS:

• First of all, select the E8 cell and write the following formula:
`=DELTA(C5,D5)` • Secondly, press Enter and you can the result.
• After that, drag the formula from E5 to F9 cells with the help of AutoFill. • Now, you can observe the result.
• Here,1 indicates the age of the child is 7.
• And 0 indicates the age of that child is not 7. ## Conclusion
