Similarly, you can display negative percentages in parentheses by creating a custom format that resembles this one: 0.00%_) (0.00%). The portion that follows the semicolon represents the format that is applied to a negative value. When applied to cells, this format displays positive percentages in the default text color and negative percentages in red. The format should resemble the following: 0.00% -0.00%. If you want negative percentages to stand out-for example, you want them to appear in red-you can create a custom number format ( Format Cells dialog box, Number tab, Custom category). Cells that are formatted with the General format have no specific number format. To reset the number format of selected cells, click General in the Category list.

For example, typing 10 or 0.1 both result in 10.00%. Numbers equal to and larger than 1 are converted to percentages by default and numbers smaller than 1 are multiplied by 100 to convert them to percentages. To learn more about calculating percentages, see Examples of calculating percentages.įormatting empty cells If you apply the Percentage format to cells, and then type numbers into those cells, the behavior is different. If you then format 0.1 as a percentage, the number will be correctly displayed as 10%. For example, if a cell contains the formula =10/100, the result of that calculation is 0.1. Percentages are calculated by using the equation amount / total = percentage. To accurately display percentages, before you format the numbers as a percentage, make sure that they have been calculated as percentages, and that they are displayed in decimal format. For example, if a cell contains the number 10, Excel multiplies that number by 100, which means that you will see 1000.00% after you apply the Percentage format.
