A variance has several meanings in business. In an accounting sense, a variance is the difference between an actual amount and a pre-determined standard amount or the amount budgeted. In a statistical sense, a variance is a measure of the amount of spread in a distribution.
Most budget analysts calculate a variance by subtracting the budget figure from the actual spending figure. And, they normally report variance both as an amount and as a percentage of the budget figure. This is because both figures are helpful, later, for variance analysis.
