Percent variance is also known as percent change. The percent variance shows the percent increase or decrease from the original number. Percent variance is used in areas such as business, where an analyst will calculate the percent variance between income statement and balance sheet accounts. For example, an analyst may want to know the percent variance between a firm's revenues from last year to this year. To find percent variance, the analyst only needs the current period's numbers and the previous period's numbers.
