For example, to calculate 30% of 100, you would enter “30%*100” in the cell. Excel will then calculate the result and display it in the cell.

**Format Numbers as Percentages**

Formatting numbers as percentages in Excel is a simple process. Start by selecting the cell or range you want to format. Then, right-click and select “Format Cells.” In the “Format Cells” dialog box, click on the “Percentage” category and select the number of decimal places you want to display. Click “OK”, and Excel will automatically format the selected cells as percentages.

**Calculate the Percentage Increase or Decrease**

Microsoft Excel is a great tool to calculate the increase or decrease in percentage between two numbers. To calculate the percentage increase, subtract the original value from the new value, divide the result by original value, and multiply by 100. To calculate the percentage decrease, simply reverse the order of the values.

For example, if the original value was 100 and the new value is 120, the percentage increase would be calculated as follows: (120-100)/100*100=20%

**Use Conditional Formatting for Percentages**

Excel’s conditional formatting feature can highlight cells that contain specific values or meet certain criteria. To use conditional formatting for percentages, select the cell range you want to format, click on “Conditional Formatting” in the “Home” tab, and select “Highlight Cell Rules” and “Greater Than.” After that, Enter the percentage value you want to use and choose a formatting option, such as a different colour or bold text. Excel will then apply the formatting to any cells that meet the specified criteria.

**Calculate Percentages of the Total**

Excel can also be used to calculate the percentage of a total. To do this, first, calculate the total value by summing the values in the range. Then, divide each value by the total value and multiply with 100.

For example, if you have a range of values in cells A1 to A10 and the total values in cell B1, you can calculate the percentage of each value as follows: =A1/B1100, =A2/B1100, and so on.
