Full Definition of Variance

In standard costing and budgetary control, the variance is the difference between the standard or budgeted levels of cost (or income) of an activity and the actual costs incurred (or income achieved). If actual performance is better than standard then a favourable variable occurs, whilst conversely, if actual performance is worse, then there is adverse variance.

Adverse variances are usually subject to detailed analysis in order to pinpoint its exact cause(s).
