**Formatting Cells**

Formatting cells in Excel is an essential step when working with percentage calculations. By formatting cells as percentages, users can display the results in a format that is easy to read and understand. Here are some tips on how to format cells for percentage calculations in Excel:

- To format cells as percentages, select the cells you want to format, right-click, and select “Format Cells.” Alternatively, you can click on the “Home” tab, select “Number” from the “Number” group, and then select “Percentage.”
- In ‘Format Cells’ dialogue box, under the “Number” tab, select “Percentage” from the Category list.
- By default, Excel formats percentages with two decimal places. However, if you want to display more or fewer decimal places, you can change the number of places shown. To do this, click on the “Number” tab, select “Custom” from the Category list, and then enter the desired number of decimal places in the “Type” box.
- Select the cells to apply the formatting to a range of cells, and then press “Ctrl + 1” to open the “Format Cells” dialogue box.
- Following these steps, users can format cells as percentages to display their calculations’ results correctly. This makes it easier to interpret and understand the data, and it also helps to present the data in a professional and organised manner.

**Basic Percentage Calculations**

Performing basic percentage calculations in Excel is essential when working with numerical data. Here are some tips on how to perform basic percentage calculations in Excel:

**Calculating the Percentage of a Number Using the Percentage Operator (%):**

To calculate the percentage of a number, multiply the number by the percentage you want to calculate and add the percentage operator (%). For example, to calculate 20% of 100, enter “=100*20%” in a cell. Excel will display the result as 20.00.

**Calculating a Percentage Increase or Decrease Between Two Values:**

To calculate increase or decrease in percentage between two values, subtract the old value from the new value, divide the result by the old value, and then multiply the result by 100 to get the percentage. For example, if the old value is 100 and the new value is 150, the percentage increase would be [(150-100)/100] x 100 = 50%.

Alternatively, you can use the following formula to calculate the percentage increase or decrease: (New value – Old value) / Old value x 100%. For example, to calculate the percentage increase from 100 to 150, enter “=(150-100)/100*100%” in a cell. Excel will display the result as 50.00%.

Using these simple formulas, users can efficiently perform basic percentage calculations in Excel, such as discounts, markups, commissions, and taxes. It is an important skill for those who work with numerical data and wants to make data-driven decisions.

**Advanced Percentage Calculations**

Excel provides several advanced functions for performing complex percentage calculations. Here are some tips on how to perform advanced percentage calculations in Excel:

**Calculating the Percentage of the Total Using the Sum Function and Absolute Cell References:**

To calculate the percentage of a value in a range of cells, divide the value by the total sum of the range of cells and multiply by 100. Use absolute cell references to ensure the formula works correctly when copied to other cells.

For example, to calculate the percentage of sales for a particular product, enter “=B2/$B$10*100%” in cell C2, where B2 is the product’s value, and B10 is the total sales. Next, paste the formula to other cells in the column.

**Calculating a Percentage Distribution Using the Countif and Sum Functions: **

To calculate the percentage distribution of a value in a range of cells, use the COUNTIF function to count the number of cells that meet a specific condition and the SUM function to calculate the total sum of the range of cells.

For example, to calculate the percentage distribution of students who scored above 80 on a test, enter “=COUNTIF(B2:B10,”>80″)/SUM(B2:B10)*100%” in cell C2, where B2:B10 is the range of cells that contain the scores. Next, paste the formula to other cells in the column.

These advanced functions allow users to perform complex percentage calculations and gain deeper insights into their data. These calculations can help users analyse trends, identify patterns, and make data-driven decisions. It is an important skill for anyone who wants to Excel in data analysis and management.

**Tips and Tricks**

Excel provides several shortcuts and formulas to help users speed up percentage calculations. Here are some of the tips and tricks to improve efficiency when working with percentages in Excel:

**Using Shortcuts:**

- To enter a percentage value, type the number followed by the percentage symbol (%).
- To convert a decimal value to a percentage, multiply by 100 and add the percentage symbol (%).
- Use the Increase Decimal or Decrease Decimal buttons on the Home tab to change the number of decimal places displayed quickly.
- Using formulas:
- To calculate the percentage of a value, use the formula “=value*percentage%”.
- To calculate the percentage increase or decrease between two values, use the formula “=(new value-old value)/old value*100%”.
- To calculate the percentage of the total, use the formula “=value/sum(range)*100%”.
- Common errors to avoid:
- Using the wrong formula when calculating percentage changes, such as subtracting the old value from the new value instead of the other way around.
- Not using absolute cell references when copying formulas can result in incorrect results.
- Forgetting to format cells as percentages can do reading and interpreting data difficult.
