## 2 Quick Ways to Make an Excel Spreadsheet to Calculate Percentage Automatically in Excel

Calculating percentage is a common mathematical operation that we use in our everyday life. Although we can do it manually, **Excel** makes it super easy to automate percentage calculation in large data sets. That also, in a very short time. This is what I want to show you today.

### 1. Use of Excel Formula to Make an Excel Spreadsheet Automatically Calculate Percentage

In the following **3** methods, we are going to use **excel** formulas and functions to automatically find out percentage values.

#### 1.1 Using Conventional Percentage Formula

The conventional formula is the simplest way to get our percentage value for a data set. Let us see how. We are using a data set that has the total number of Covid-affected patients and the number of deaths in **America**.

**Steps:**

- First, select cell
**C8**. - Next, double click on cell Type the following formula in that cell:

`=C5/C6`

** **

- Then hit
**Enter**. - As a result, we get the following decimal number in cell
**C8**. But it is a bit long. - So, we will format this value.

- For that, select cell
**C8**, and go to the**HomeÂ**tab. - Then, navigate to the
**Number**option there, and press the**%**button.

- Now, we have our value in a percentage format.
- In addition, you can change the number of
**decimal points**by clicking the increase/decrease decimal button just below the**%**.

#### 1.2 Apply Excel IFERROR Function

This method can be really helpful if you have a zero-valued cell. The conventional method might produce some errors in this case. So, we use **the IFERROR function** to avoid any errors. Here, we have an exam mark sheet for four students.

**Steps:**

- To begin with, we have
**2**cells with a value of**0**. - In addition, double click cell
**E5**and enter the following formula:

**=IFERROR(C5/D5,0)**

- Press
**Enter**. At this time, you should see the following result. - Also, at the lower right corner of the current cell, you see the
**Fill Handle**. - Now, Click and drag the Fill Handle to copy the
**IFERROR**function to the remaining cells.

- So, you have finally got your percentage values for all the cells.

#### 1.3 Calculation of Percent Increase or Decrease Automatically

In **Microsoft Excel**, we can calculate an increase or decrease in values very easily. Weâ€™ll be using yearly income change to understand this method.

**Steps:**

- Firstly, select cell
**E5**and type the following formula:

**=(D5-C5)/C5**

- Then, hit Enter. You should get the following result.
- Next, drag the
**Fill Handle**tool to copy this formula to other cells in the column.

- Finally, you get the value for all peopleâ€™s income change in percentage.
- It is important to note that the minus sign in cell
**E8**denotes a decrease in salary.

### 2. Auto Calculate Percentage of Contiguous Cells in Excel Using Absolute Reference

**The absolute reference** method comes in really handy when we want to calculate the percentage with respect to a certain cell. To illustrate this method we will use the following dataset. Letâ€™s jump right into it:

**Steps:**

- To start with, click on cell
**D5**and type this formula:

**=C5/$C$9**

- Also, you can use the
**F4**key to quickly enter the dollar sign for**C9**.

- Now, press the
**Enter**key and you get the following result. - Again, you can format the decimal places as you need.

- Like we did previously, drag the
**Fill Handle**to copy the formula for the remaining cells in the column. - Importantly, the second cell reference stays as
**C9**for all the cells below. - This is because we used the absolute reference using the
**$**. - Finally, we get the percentage of the obtained marks with respect to the total marks in cell
**C9**.

## Conclusion

I really hope that you clearly understood all of the methods to automatically calculate percentages in **Excel**. And not only that, but you should now be able to apply these methods in various cases, as needed. Donâ€™t forget to download the workbook we provided and practice with the given dataset. You should also practice using your own sets of data. To learn more quick and easy methods in **Excel**, follow our **ExcelDemy** website. If you have any queries, please let me know in the comments.
