Now imagine that after your first year, you actually made money, earning $12,000. Calculating the percent variance between your actual revenue and budgeted revenue would give you –220%. You can try it on a calculator. 12,000 minus –10,000 divided by –10,000 equals –220%.
WebStep 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations. Step 3: Square each deviation to make it positive.
