Favorable Variance

A favorable variance is a difference between an actual result and a budgeted or standard amount that makes profit higher than planned. For revenue, a variance is favorable when actual revenue is greater than budgeted revenue. For costs, it is favorable when actual costs are less than budgeted or standard costs. The opposite, a difference that reduces profit, is called an unfavorable or adverse variance.

Variances are the main tool of variance analysis, a branch of management accounting in which managers compare what happened with what was expected and look for the reasons behind the gaps. A favorable variance is usually labelled "F" in a variance report, while an unfavorable one is labelled "U" or "A." The broader concept is described in the entry on budget variance.

The basic calculation subtracts the budget from the actual figure:

Here $\text{Actual amount}$ is the recorded result for the period and $\text{Budgeted amount}$ is the figure in the budget or standard. The sign alone does not tell you whether the variance is favorable; you must also know whether the line is revenue or cost. A positive variance on a revenue line is favorable, while a positive variance on a cost line is unfavorable.

A bakery budgets monthly sales of $50,000 and ingredients costs of $18,000. Actual sales are $53,500 and ingredients cost $17,100.

• The sales variance is $53,500 minus $50,000, which is $3,500 favorable, because revenue exceeded the plan.
• The ingredients variance is $17,100 minus $18,000, which is negative $900, and that is $900 favorable because the bakery spent less than budgeted.
• Together these two lines improved profit by $4,400 compared with the budget.

In a standard costing system the cost variance can be split further. Suppose the standard for one cake is 0.5 kilograms of flour at $2.00 per kilogram, and the bakery makes 4,000 cakes using 1,900 kilograms bought at $2.10. The material quantity variance is (1,900 minus 2,000) times $2.00, which is $200 favorable, because less flour was used than the standard allowed. The material price variance is ($2.10 minus $2.00) times 1,900, which is $190 unfavorable. The net result is a $10 favorable variance, but the detail shows two quite different stories that a single number hides.

A favorable variance is not automatically a sign of good management. Some common explanations are less flattering:

• A favorable materials price variance may come from buying cheaper, lower-quality inputs that later cause scrap, returns or abnormal spoilage.
• A favorable maintenance or training variance may simply mean that necessary work was postponed, storing up larger costs for later.
• A favorable cost variance compared with a static budget may reflect lower sales volume rather than efficiency, since variable costs naturally fall when output falls.
• A favorable variance across the board may indicate budgetary slack, in which managers set easy targets so they can beat them.

To avoid the volume problem, analysts usually compare actual results with a flexible budget adjusted to the actual level of activity. Only then do cost variances show genuine changes in spending or efficiency.

Most companies set a threshold, such as 5 percent or a fixed dollar amount, above which any variance, favorable or not, must be explained. This approach, known as management by exception, keeps attention on the items that matter. Variance analysis also feeds into future budgets and pricing, and helps link spending to cost centers and managers who can control it. In external reporting, variances do not appear as separate lines: under absorption costing, standard cost variances are closed to cost of goods sold or allocated to inventory at the end of the period.
